Major enterprises at home and abroad have made corresponding measures

Recently, Graham Partners (New Town Plaza, Pennsylvania), a private investment company for industrial technology and advanced manufacturing companies, announced the investment of a thermoformed plastic packaging supplier, Simple Parker LLC, to strengthen the company as a top-sized mid-range thermoforming machine. success. Graham said his investment value is a strong future market for thermoformed plastic packaging. At the same time, Tianjin Petrochemical's olefins department successfully launched a high-strength thermoformed polypropylene special material PPR-EM01, which was sent to downstream customers to enter the sample stage. This product fills the blank of similar products in China.

High-stiffness thermoformed blister polypropylene packaging film is used in food packaging, pharmaceutical packaging and other fields, and the market demand is huge. At present, domestic thermoforming special materials mainly rely on imports. A few domestic processing enterprises use two or three kinds of polypropylene resins to mix and produce according to a certain proportion, but the processing is difficult and the quality fluctuates greatly.

Current thermoplastic packaging application status

At present, low-end plastic packaging does not use "high-barrier plastics". When heating or placing hot foods, toxic substances are decomposed, and plasticizer is one of them. Plasticizers are large-scale industrial products, which are widely used in various fields of the national economy, including plastic bags, cling film, plastic cooking oil drums and other products that people often use, which contain a large amount of plasticizer. Plasticizer is a kind of polymer material auxiliaries, and it is also a phthalate ester in environmental estrogen. There are many kinds of phthalates. The most common variety is DEHP (trade name DOP). The role of plasticizer is similar to artificial hormones, which will promote female precocious puberty and harm male reproductive ability. Long-term high intake will lead to liver cancer; because young children are in the endocrine system of reproductive system development, it will bring great potential harm to children. Therefore, the state continues to increase management efforts in maintaining the safety of food plastic packaging. Recently, the 14 departments of the State Council Food Safety Office jointly issued documents requiring catering enterprises not to use plastic products containing plasticizers to store grease and oils. This initiative indirectly promotes the rapid development of the “high barrier plastic” packaging industry.

According to the report, food packaging not only protects food, but also uses it as a tool to promote sales. This transformation has greatly increased the market size of high barrier bags. In developing countries, changes in public lifestyles and increased incomes have contributed to market growth. Technological advances in product design, prevention of moisture loss, and freshness of the product are major factors contributing to the high demand for high barrier bags.

Nowadays, while pursuing high-quality life, people are more inclined to choose products that are beneficial to the environment and health. Thermoformed “high barrier plastics” will become a new benchmark for the development of packaging companies.
