The growing urban lifestyle of consumers in Thailand has been driving demand for packaged convenience food. New trends in packaging technologies e.g. smart packaging, active technology, RFID., etc. can be used as a business tool for a competitive advantage in the food industry to comply with consumer lifestyles.
This paper aims to identify and validate the decision factors for selecting new trends of food packaging technology to support the food packaging industry in Thailand in producer firms’ viewpoints. Firstly, the author reviewed the literature to find out general factors in selecting any technologies to set guideline for design questions in questionnaires about decision factors in selecting food packaging. Secondly, the questionnaires were distributed to 40 representatives of food packaging firms in Thailand to find out their decision factors concerned. By the facts that the development of new trends of packaging in Thailand is mostly driven by only large firms. Hence, thirdly, the author performed in-depth interviews with executives in 8 leading and top largest food firms in Thailand to confirm that advanced packaging technology whether has opportunities of growth in the food industry in Thailand or not.
Respondents from food packaging firms in Thailand expressed their interests in four areas in selecting new technology of packaging, including (1) the technology aspect, (2) marketing and business competition aspect, (3) financial and economical aspect, and (4) strategy, society and environment aspect.
A lack of raw materials and local technology still make the cost prohibitive to boom the advanced packing.

Both market competition in recent business and marketing strategies of firms to increasing customer satisfaction and maximum gains of their firms have effects on the development of new products. In the food industry, the packaging is the core component having strategical and tactical uses in marketing functions. Advanced packaging is a key component to reach a competitive edge of any companies [1Coles R. Food Packaging Technology 2003.]. Presently, innovation of packaging technologies including materials and processes has led to the development of a large number of convenience foods in the market [2Bindu J, Ravishankar CN, Gopal TKS. Packaging of retort-processed seafood, meat and poultry 2012; 333-62. [http://dx.doi.org/10.1533/9780857095718.3.331] ]. Using advanced packaging to add values to instant food is a strategy to enhance the interests of consumers, together with maintaining the quality of products. With current trends of environmental protection, new regulations are enacted. It leads to breakthroughs in technology and efforts to improve technologies in commercial use with reasonable expenses [3Vanderroost M, Ragaert P, Devlieghere F, Meulenaer BD. Intelligent food packaging: The next generation. Trends Food Sci Technol 2014; 39: 47-62. [http://dx.doi.org/10.1016/j.tifs.2014.06.009] ]
Smart food packaging is important to the food industry and instant food. Currently, firms in developed countries have improved various packaging technologies to fit with the applications to comply with the lifestyles of consumers and meet with the new standard of environmental friendliness regulations. In Thailand, the food packaging industry has to develop packaging technology to be competitive in terms of innovative technology and suitable applications to support both domestics and export sales. Entrepreneurs need to be alert to continuous development the capabilities of manufacturing, availability of technology and collaboration in research between the public sector (research institutes and universities) and the private sector (food manufacturing firms and packaging manufacturing firms). However, the applications of smart technology food packaging are related to major investment and a high degree of uncertainty whether it will be a success in the market or not. Therefore, the decision to select any advanced technologies is important and needs to identify a lot of factors affecting selection. Those factors cover with technology aspect, marketing and business competition aspect, financial and economic aspect, and strategies, society and the environmental aspect.
2. LITERATURE REVIEW
There are at least two factors driving new technology in the food industry such as Research and Development (R&D) activities, and market orientation [4Grunert KG, Harmsen H, Meulenberg M, Kuiper E, Ottowitz T, Declerck F, et al. A framework for analyzing innovation in the food sector.Product and process innovation in the food sector 1997.]. Packaging R&D is considered as the key factor driving technological change in the food industry, which is closely linked with innovational industrial stings, and technological change is a necessary condition for innovation in the firms [5John EE. Policy implications of the innovation process in the U.S. Food sector. Res Policy 1983; 12: 239-67. [http://dx.doi.org/10.1016/0048-7333(83)90018-5] , 6Huiban JP, Bouhsina Z. Innovation and quality of labour factor: An empirical investigation in the French food industry. Small Bus Econ 1998; 10: 389-400. [http://dx.doi.org/10.1023/A:1007967415716] ]. Technological change can be achieved through investment in the technological and scientific capabilities of the workforce [7Leiponen A. Competencies, innovation and profitability of Firms. Econ Innov New Technol 2000; 9(1): 1-24. [http://dx.doi.org/10.1080/10438590000000001] ]. Product technology capabilities are needed for successful innovation. Market orientation may be defined as the detection and fulfilment of needs and wants of potential customers using the skills, resources and competencies of the company [8Grunert KG, Baadsgaard A, Harting-Lasen H. Madsen TK Market Orientation in food and agriculture 1996. [http://dx.doi.org/10.1007/978-1-4613-1301-4] ].
Future trend in the food packaging technology includes of several technologies, for example, high barrier materials, nanotechnology, and improving of convenience features of packaging related to production, distribution, sales, marketing, consumption, waste disposal, food safety, environmental friendliness and smart packaging [9Han JH. Emerging technology in food packaging: Overview 2005., 10Han JH. A review of food packaging technologies and innovations 2014; 4-11. [http://dx.doi.org/10.1016/B978-0-12-394601-0.00001-1] ]. Advanced food packaging technologies are based on the packaging that has various functions in protection, convenience, communication and containment [11Yam KL, Lee DS. Emerging Food Packaging Technology 2012. [http://dx.doi.org/10.1533/9780857095664] ]. Moreover, trends in food packaging also cover about the sustainability of packaging, taste and healthiness to food, consciousness and demand from consumers’ side, and conveniences in usage [12Ragaert P. Food packaging: technology and possibilities 2012. Available from: http://ebookbrowsee.net /fo/food-packaging-technology-pdf#.Uy7q4fmSxBx].
Active packaging is the incorporation of specific substances into packaging systems to maintain or extend the food properties or provide information of packaging environment and food status to the processor, retailer, consumer [13Kerry JP, O’Grady MN, Hogan SA. Past, current and potential utilisation of active and intelligent packaging systems for meat and muscle-based products: A review. Meat Sci 2006; 74(1): 113-30. [http://dx.doi.org/10.1016/j.meatsci.2006.04.024] [PMID: 220 62721] ]. The primary active technologies mostly enhance the shelf life of the products, although active packaging may perform other functions as well. There are many applications of active packaging such as absorbers and emitters of gas and volatile substances, antimicrobials, and antioxidants [14Brody AL, Trupinsky ER, Kline LR. Active packaging for food application Technomic Publishing Company 2001; 218., 15Janjarasskul T, Suppakul P. Active and intelligent packaging: The indication of quality and safety, Critical reviews in food science and nutrition 2016; 1-24. Published online: 19 Sep 2016].
Absorbers and emitters of gas and volatile substances are one kind of active solution. It aims to control packaging headspace composition during storage. These devices can be divided into two main categories: scavengers or absorbers and emitters. The term scavenger is usually applied to fast-acting substances, able to intercept gaseous or volatile compounds and react chemically with them. The term absorber can be used when the reaction between the gas and the active substance is based on the physical mechanism of absorption during which molecules enter some bulk phase usually made from a solid material. Examples of compounds with absorption function are activated carbon and other molecular sieves. Oxygen, carbon dioxide and ethylene are gases that differently affect the shelf life of some food and, for this reason, a large number of active solutions exist based on their ability in removing or releasing these gases [16Limbo S, Khaneghah AM. Active packaging of foods and its combination with electron beam processing 2015; 196-217. [http://dx.doi.org/10.1533/9781782421085.2.195] ].
Antimicrobial active packaging has significantly increased during recent few years as an alternative method for controlling microbial contamination of food based on incorporating antimicrobial substances with inherent antimicrobial properties in or coated onto the packaging material to reduce or inhibit microbial growth [17Dainelli D, Gontard N, Spyropoulos D, Beuken EZ, Tobback P. Active and Intelligent food packaging: Legal aspects and safety concerns. Trends Food Sci Technol 2008; 19: S103-12. [http://dx.doi.org/10.1016/j.tifs.2008.09.011] , 18Campos-requena VH, Rivas BL, Perez MA, Pereira ED, Garrido-miranda KA, Peraira ED. Polymer/ Clay nanocomposite films as active packaging material: Modeling of antimicrobial release. Eur Polym J 2015; 71: 461-75. [http://dx.doi.org/10.1016/j.eurpolymj.2015.08.018] ]. There is a difference between the antimicrobial solution formulated to preserve and extend shelf life and, those able to target specific pathogenic species. The antimicrobial activity may exist in the packaging material, in direct contact with the food surface, or in the package headspace, depending on the volatility of the substance. Incorporation methods and transferring/ releasing techniques are critical in designing an effective antimicrobial packaging system [16Limbo S, Khaneghah AM. Active packaging of foods and its combination with electron beam processing 2015; 196-217. [http://dx.doi.org/10.1533/9781782421085.2.195] ].
Oxidation of lipids in the food causes a reduction in shelf life due to changes in taste and odor, tissue disruption, and reduction of food functionality and nutritional quality. Food oxidation can be avoided by using oxygen holders or antioxidant substances in the packages. This type of packaging is designed to slow down or prevent the oxidation reaction that influences food quality [19Eker B, Icoz A. Smart, active and Sustainable food packaging 2017; 2nd International Conference on Quality of Life; June 2017; Center for quality, Faculty of Engineering University of Kragujevac 2017; pp. 293-301.]. Active packaging represents an innovative strategy to incorporate antioxidants in a polymer to prevent oxidative processes and extend the shelf life of the food product. Antioxidant agents can be applied into the packaging system in different forms such as sachets, and labels, coating or immobilization on the packaging material surface, incorporated into the polymer matrix, multilayer films, etc. [20Realini CE, Marcos B. Active and intelligent packaging systems for a modern society. Meat Sci 2014; 98(3): 404-19. [http://dx.doi.org/10.1016/j.meatsci.2014.06.031] [PMID: 2503 4453] ].
Intelligent packaging systems have components that sense the environment and process the information and then allow the action to protect the product by conducting communication functions [21Yam KL, Takhistov PT, Intelligent packaging JM. Concepts and applications. J Food Sci 2005; 70.]. An intelligent packaging system is capable of detecting, sensing, recording, tracking, or communicating information about the quality and/or the state of the product during the whole food chain. The package will provide information to the processor, retailer and/or consumer regarding the status of the food, not only about the product itself, but will also be able to inform about the history of products in terms of storage conditions, headspace composition, microbial growth, etc. [19Eker B, Icoz A. Smart, active and Sustainable food packaging 2017; 2nd International Conference on Quality of Life; June 2017; Center for quality, Faculty of Engineering University of Kragujevac 2017; pp. 293-301., 20Realini CE, Marcos B. Active and intelligent packaging systems for a modern society. Meat Sci 2014; 98(3): 404-19. [http://dx.doi.org/10.1016/j.meatsci.2014.06.031] [PMID: 2503 4453] ]. summarized intelligent packaging technology as follows:
Sensors: Sensors which are applied in food packaging display the freshness of the food, microbial spoilage in products (if any), oxidative rancidity, and changes depending on temperatures. When sensors are integrated with the food packaging, good chemicals, pathogens and toxins can be determined. Some examples of this are gas sensor packaging, biosensor packaging, etc.
Indicators: For the period when food is in the package, various indicators for features such as temperature, microbial disruption, packaging integrity, physical shock, and originality are functioning. While some of the indicators get in reaction with the food, some of them can provide information without getting into any reactions.
Leakage Indicators is the system showing the existence or lack of certain gases and provides information about package integrity and leakages. Leakage indicators change color as a result of chemical and enzymatic reactions. Indicators can be in the form of tablets, labels, and printing and they can also be formulated by coating the polymer film.
Freshness indicators give direct immediate product quality information resulting from microbial growth or chemical changes within a food product. Microbiological quality may be determined visually through the reaction between microbial growth metabolites and integrated indicators within the package. Freshness detectors are used for determining carbohydrate diacetyl, amine, ammonia, and ethanol, all of which are in the packaging. They are systems that work for determining the metabolites and the change has concentrations as a result of the violation of required conditions in the storage of food and due to the microbial disruption [19Eker B, Icoz A. Smart, active and Sustainable food packaging 2017; 2nd International Conference on Quality of Life; June 2017; Center for quality, Faculty of Engineering University of Kragujevac 2017; pp. 293-301., 22Riva M, Piergiovanni L, Schiraldi A. Performance of Time Temperature indicators in the study of temperature exposure of packaged fresh foods. Packag Technol Sci 2001; 14: 1-9. [http://dx.doi.org/10.1002/pts.521] ]. Freshness indicators can also be used to provide an estimate about the remaining shelf life of perishable products.
Time-Temperature Indicators (TTI) is a device to imitate the change relating to a food product being subject to the same temperature, as within a specific quality parameter. Time-Temperature indicators show the temperature applied during distribution with color variations with respect to mechanical, chemical, electro chemical, enzymatic, or microbial changes. Time-Temperature indicators are labels that are prepared for providing continuity of food safety and quality and for monitoring the temperature changes in the distribution and storage process [19Eker B, Icoz A. Smart, active and Sustainable food packaging 2017; 2nd International Conference on Quality of Life; June 2017; Center for quality, Faculty of Engineering University of Kragujevac 2017; pp. 293-301.].
There are other intelligent packaging technologies that do not fall into either the sensor or indicator classification. Radio Frequency Identification System (RFID) is grouped under the term automatic identification, together with barcodes, QR-codes, magnetic inks, etc. [3Vanderroost M, Ragaert P, Devlieghere F, Meulenaer BD. Intelligent food packaging: The next generation. Trends Food Sci Technol 2014; 39: 47-62. [http://dx.doi.org/10.1016/j.tifs.2014.06.009] ]. RFID is a system that allows identification with radio waves while providing opportunities for remote monitoring of the product. The final benefits of RFID in food packaging are speeding up the stock turnover and improving monitoring. By establishing the RFID system at the markets, information can be automatically reached with respect to the number of products remaining on the shelf, quantity of stock in the warehouse, products themselves, the shelf lives of items near expiry, and whether products are preserved under correct temperatures or not [21Yam KL, Takhistov PT, Intelligent packaging JM. Concepts and applications. J Food Sci 2005; 70.].
Another consideration is environmentally friendly packaging. An important strategic issue facing the food industry is the political and public pressure over the environment, particularly in relation to concerns over the amount of packaging and packaging waste. Environmental policy on packaging should focus on resource efficiency and not just waste and recycling [1Coles R. Food Packaging Technology 2003.].
Since it is the psychological process in decision making. Consumer decision is another factor to be considered about. Socio-demographic factors such as income, racial profile, presence of children; education level and age have significant effects on the demand for functional enhancements [23Gulseven O, Wohlgenant M. Demand for functional and nutritional enhancements in specialty milk products. Appetite 2014; 81: 284-94. [http://dx.doi.org/10.1016/j.appet.2014.06.105] [PMID: 2499 7409] ]. Moreover, the packaging, price and brand image are the primary characteristics that affect consumers’ decision especially in some kinds of products like milk [24Gulseven O. Estimating factors for the demand of organic milk in Turkey. Br Food J 2018; 120(9) [http://dx.doi.org/10.1108/BFJ-12-2017-0712] , 25Wasana K, Manuspiya H, Chaisuekul C, Ploykitikoon P. Selection Criteria for Food Packaging innovation in Thailand. Int J Mecha Pro Eng 2015; 3(9): 61-5.].
According to technology availability, the trend of food packaging technology can be summarized as shown in Fig. (1).
The growing urban lifestyle of consumers in Thailand has been driving demand for packaged convenience food items. Convenience stores are gaining importance for Thais amid the urbanization of the country and are looking at the growing demand for convenience in the south-east Asian country. At present, Thailand has recognized the importance of the development of food packaging in terms of creative packaging. The National Innovation Agency of Thailand, in 2010 and again in 2013, expressed concern with three components: functionality, emotional consideration and materials. This includes packaging that is designed by applying any one of these components to emphasize on the usability such as active packaging, intelligent packaging and biodegradable packaging made from bioplastics [26Peelman N, Ragaert P, Meulenaer BD, Adons D, Peeters R, Cardon L, et al. Application of bioplastics for food packaging. Trends Food Sci Technol 2013; 32: 128-41. [http://dx.doi.org/10.1016/j.tifs.2013.06.003] , 27Rhim JW, Park HM, Ha CS. Bio-nanocomposites for food packaging applications. Prog Polym Sci 2013; 38: 1629-52. [http://dx.doi.org/10.1016/j.progpolymsci.2013.05.008] ]. The pathway of food packaging technology in Thailand is shown in Fig. (2).
2.1. Research Objectives
Hence, this paper aims to identify and validate the factors in selecting smart food packaging technology of food packaging firms from their viewpoints and their decision insights.
Firstly, the author reviewed the literature to find out general factors in selecting any technologies to set guideline for design questions in questionnaires about decision factors in selecting food packaging. Questionnaires are designed by using five points Likert scales to ranking the degrees of importance of those factors in respondents’ opinions.
Secondly, by purposive sampling technique, sample groups are 40 leading firms who participated in a seminar of the National Food Institute of Thailand in 2015. Questionnaires were distributed to them to find out their concerned decision factors. Collected data were analyzed by using average points of each factor.

Fig. (2) Pathway of Food Packaging Technology.
By the facts that the development of smart packaging in Thailand is mostly driven by only large firms. Hence, thirdly, the author performed in-depth interviews with executives in 8 leading and top largest food firms in Thailand to confirm that advanced packaging technology whether has opportunities of growth in the food industry in Thailand or not. All of them were considered innovators or leading food firms in the food industry, government agencies, and universities in Thailand. The interview questions were open-ended questions focused on the strengths, weaknesses, opportunities, and threats of using new packaging technology. Interview duration was once for around 60-90 minutes. After that, the author summarized the main ideas of the answers received. The results of interviews were analyzed by using a SWOT analysis for assessing the situation of business operation on new technology.
Factors for selecting the novel food packaging
The factors for selecting the new food packaging are summarized in Table 1.
Table 1 Factors of selecting smart food packaging.
Results from questionnaires surveyed with 40 firms in the food industry in Thailand revealed that the firms considered factors in four areas including technology aspect, marketing and business competition aspect, financial and economic aspect. The overall average scores of 19 sub-factors in four main areas that influence the selecting of the packaging technology were between 3.20 - 4.60 points from 5 point scale.
The most concerned factors by firms are “Effect on ex-isting market share” factor with the highest score of 4.8 points.
The second most concerned factors by firms are “Human health Impact”, “Environmental Impact” and “Advancement” factors with equal score of 4.4 points.
The third most concerned factors by firms are “Regulatory Impact”, “Image / Reputation”, “Financial status”, “Potential return on investment” and “New market potential” factors with equal score of 4.2 points.
Considered by aspects, the results are described as follows:
From technology aspect: the most important factor is “advancement” of technology with 4.4 points, followed by “Reliability” and “Feasibility” factors with equal scores of 4.0 points. The less important factors are “Technology risk” and “Raw material availability” factors with 3.2 and 3.0 points, respectively, as depicted in Fig. (3).
From marketing and business competition aspect: the most important factor is “Effect on existing market share” of technology with 4.8 points, followed by “New market potential” with 4.2 points, “Business risk” factors with 4.0 points. The least score of “Timing to market” is 3.2 points, as depicted in Fig. (3).
From financial and economic aspect: the most important factor is “Potential return on investment” and “Financial status” with an equal score of 4.2 points. It is followed by “Initial Investment” factors and “Price of product” with equal score of 4.0 points. The least important factor is “Payback period” with 3.8 points, as depicted in Fig. (3).
In strategy, social and environment aspect: the most important factor is “Environmental Impact” of technology and “Human heath Impact” with equal score of 4.4 points. It is followed by “Image / Reputation” factors and “Regulatory Impact” with equal score of 4.2 points. The least important factor is “Patentability” with 3.4 points, as depicted in Fig. (4).

Table 2 SWOT Analysis of interview results about the selection of new packaging technology.
Results from the interview from executives in 8 leading large food firms in Thailand are summarized in Table 2.
The findings of the current study supported that the most important factor is “effect on the existing market share”. It implied that whenever smart packaging is applied in Thailand, the firms are still concerned with the existing market, so it should not adversely impact the existing market.
Human health impact factor and environmental impact factor are the next concerned factors which mean that in the food industry in Thailand, the attributes about health and environment are interesting issues for the customers. Then the producers have to be concerned about them in high priority.
The factors about marketing and business are quite important. While the technology and raw materials seemed to be less concerned. It may imply that the technology for food packing in Thailand are prompted to implement in the industry whenever the marketing opportunities permit. Also, the raw material for food packaging seems to be adequate or not to trouble in consumption.
The result of this research can support entrepreneurs who want to develop packaging in their own organizations by the decision factors and support the overview information of smart food packaging to adjust the strategy in their organizations.
The psychological behavior of the decision in the selection of smart packaging in the producers’ viewpoint or manufacturing firms is that they are vigilant in select new technology. Most of the large firms may use wait and see strategy to see whenever market demands or consumers’ demands reach out the large volume of market shares. They do not take the risk to be the first mover in selecting new food packaging technology until the situation is good enough.
For the decision factors, the participants rated the four main aspects including the technology aspect, marketing and business competition aspect, financial and economic aspect, and strategy, society and environment aspect with different scores. The highest score of the sub-factors is “effect on the existing market share”. Human health impact factor, environmental impact factor and advancement of packing technology factor are concerned to be second important factors. Image / reputation factor, financial status factor, potential return on investment factor and new market potential factors are the next concerns to be important. The next concerns to be important are the price of product factor, initial investment factor, feasibility factor and reliability factors. The concerns to be less important are payback period factor, patentability factor, time to market factor, technology risk and raw material availability factor.
From the interview with the firms, even though the food and packaging firms in Thailand are aware to develop new advanced packaging, however, the high cost of developing smart packaging is the obstacle to be transferred to implementation in the industry. The participants from government, universities, and the industry believe that the development approach for smart food packaging technology will be importing the technology and know-how from abroad into the country by only the leading big firms’.
The results of this research indicate some similar and some different factors compared to the past researches. In similar way, this research revealed the important factors about human health impact and environmental impact that near to the result of factors that influence public acceptance of innovative technologies and products in the food area that mentioned that the important factors were perceived benefit and perceived naturalness are important factors for the acceptance of new food technologies. In a different way, this research revealed that in a specific country (Thailand), firms perceived the existing market to be more important factors.
Since results of decision factors in this survey are independent of each other in the viewpoints of respondents. Thus, for future research, it should focus on the study of multi-factors e.g. the Analytical Network Process (ANP) tool, etc., to link the relationship of each factor. Furthermore, it may find out the weight of each factor.
