Container and Packaging Material Market
Major manufacturers in the food and beverage industry and the food industry have successively publicly pledged to reduce and de-plasticize corporate policies. Biodegradable resins, bioplastics, and other related materials companies are also becoming more active.
In this context, the Japanese city survey agency-Fuji Chimera Research Institute (Fuji Chimera Research Institute) surveyed the domestic container and packaging material market, and proposed the direction of the use of materials and the direction of product environmental problems. Analyze insights. Markets that have attracted attention include shopping plastic bags, straws, microwave-compatible plastic packaging bags, plastic packaging bags (non-food use), and polystyrene paper (PSP) food containers.
To achieve the purpose of reducing waste, Japan has continued to promote the reduction of plastic bags for shopping from the past policies such as the implementation of the self-prepared environmental bag campaign, the gift of shopping points without using plastic bags, to the charging system for plastic bags. In recent years, as marine plastic pollution has gradually developed into a global concern, the promotion of plastic reduction and plastic restriction policies has become a global trend. Japan will also implement a plastic bag charging system across the country from April 2020. Major supermarkets and retail stores The provision of free plastic bags will be banned, and it is expected that the demand for shopping plastic bags in the most used convenience stores will be halved.
The materials used in shopping plastic bags are mostly low-priced and strong high-density polyethylene (HDPE), but in recent years, the increase is that bio-polyethylene (PE) made from plants is added to HDPE Bio-PE mixed products in the. Overall, the market size of plastic bags for shopping in Japan will shrink year by year. Fuji Chimera Research Institute also estimates that the market size will be about 79.4 billion yen in 2023, which is a decrease of 28.1% compared to 2018.
Plastic pollution threatens marine life and other issues are becoming more and more serious, and all walks of life are beginning to pay attention to the environmental catastrophe caused by plastic waste. Regarding straws, Japan has rapidly suspended the use of straws or switched to alternative material straws since 2018, mainly in the food industry and hotels. Recently, convenience store operators have begun to gradually reduce the use of disposable plastic straws. It is expected that the market size of straws will show a slight decrease in the future. Compared with 2018, it will be reduced by approximately 3.0% by 2023 to 9.7 billion yen.
The material used in the straws is mainly polypropylene (PP), which has been gradually converted to paper or biodegradable resins such as polylactic acid (PLA), polylactic acid (PLA) and polybutylene succinate (PBS). Overseas, due to the expansion of plastic restriction and plastic reduction measures such as the sales and use restrictions of straws, the demand for containers such as cups without straws has also increased.
The packaging material corresponding to the microwave oven is automatically ventilated plastic packaging material that can be directly microwaved without opening or perforating. Because it can be heated without moving it to other utensils, Japan's demand for microwave packaging materials is increasing under the social background of aging and increasing single population. Although the demand for microwave packaging materials for side dishes and non-staple food in supermarkets is flat, it still maintains a high level of demand. It is expected that the demand for microwave packaging materials for staple food products will be the center in the future, and the market scale will continue to expand until 2023. It is expected to grow 2.2 times compared with 2018, reaching 18.1 billion yen.
Plastic packaging bags are surveyed with non-food plastic packaging bags that can be supplemented, such as detergents, shampoos, and shower gels. Due to the purpose of reducing the use of plastic and reducing costs, related products have gradually transitioned from plastic bottles and cans to plastic packaging bags. Among them, the demand for large-capacity plastic packaging bags that can be replenished multiple times and contain diversion ports will continue to increase, showing a steady growth trend. It is estimated that 2023 will grow 2.1 times compared with 2018. However, plastic packaging bags that do not contain diversion ports and have a relatively small volume will gradually switch to packaging with diversion ports, so the market size will shrink.
Bioplastics are entering a period of growth
The problem of microplastics pollution has attracted global attention. In addition to the increasingly active development of recycling technologies, many domestic chemical companies are also accelerating the development of biodegradable plastics, and the substitution effect of bioplastics in the market has also begun to spread. , Related development and applications will also usher in a period of growth.
Sekisui Chemical Products Industry has developed a biodegradable polymer microparticle "Techpolymer EF Series". It is a resin made from biomass materials, including water-degradable "EF-A Grade" and soil-degradable "EF-B" "Grade" two products. "Techpolymer EF-A Grade" is highly biodegradable. In the biodegradability evaluation test, the biodegradation rate of EF-A Grade in water for 50 days is over 80%, which is more than 20% of cellulose (Cellulose). Come higher. The decomposability of "Techpolymer EF-B Grade" in the soil greatly exceeds that of polylactic acid (PLA), and the biodegradability can reach close to 100% in 12 months.
The Green Science Alliance confirms that polylactic acid (PLA) compounded with cellulose nanofibers (CNF) can accelerate biodegradability. Therefore, while improving the mechanical strength, it can also promote biodegradability even if sufficient composting conditions are not reached. Degradability. The PLA/CNF composite materials developed by the Green Science Alliance have also obtained the "BiomassPla" and "GreenPla" marks issued by the Japan Bioplastics Association (JBPA). The Green Science Alliance also plans to promote the compositeization of other biodegradable plastics, such as polybutylene succinate (PBS), in addition to PLA, and make color masterbatches according to demand.
"Eneryts" developed by TOYO Styrene is a composite resin material of polystyrene and PLA. The weight ratio of PLA is about 30%. In addition to enhancing the strength of the product through additives, it also has excellent oil and chemical resistance and can be used. In the microwave. At present, "Eneryts" has obtained the bioplastic certification of the Japan Bioplastics Association, and has been registered in the Positive List of the Polyene Hygiene Association.
The plant-derived biodegradable resin PHBH developed by Kaneka has now obtained food contact certification from the U.S. Food and Drug Administration (FDA), has also been reviewed in the European Union and can be used in the European Union. Regarding Japan’s certification application as a food-contactable material, Japan Hygienic Olefin And Styrene Plastics Association (JHOSPA) has entered the final stage of the "front-listing" certification process. It is expected that food packaging will begin in Japan in 2019. Application of purpose.
To start the market supply of PHBH as soon as possible, Kaneka has also launched a joint development of PHBH food containers and packaging with 7&I Holdings, a large Japanese retail and distribution business holding company, and has launched a trial introduction in its convenience store 7-11. Food products that use 100% PHBH are also circulating in Japan for the first time. To expand its use, Kaneka plans to apply PHBH to fibers and non-woven fabrics by 2025, and replace PET resin as raw materials for PET bottles.
UNITIKA modified its self-developed bioplastic "TERRAMAC" and developed a resin for straws that has both flexibility and durability. The newly developed bio-resin is "TP-540" which has excellent processability and durability equal to that of existing plastic straws. The raw material is PLA made from plants. Under specific environments such as high temperature and high humidity, about 1 The moon will decompose into carbon dioxide and water. Since TERRAMAC has added soft ingredients and inorganic fillers, it has the appropriate flexibility and strength required for straw manufacturing. UNITIKA has also adjusted the unique sweetness of TERRAMAC, so it will not affect the flavor of food when used as a straw.
In the performance test, the durability of TP-540 to water and the rigidity when piercing beverage packaging are better than paper straws, and its performance is equivalent to ordinary plastic straws. In terms of price, under the condition of mass production, overseas examples have shown that the price of a general-purpose plastic straw is 0.5 cents, that of biodegradable plastics is 1 cent, and that of paper is 1.5 cents. Straws made of bio-plastics have an advantage in price.
