The rise of human civilization, followed by a faster way of life, especially reflected in the changes in diet, portable food has become the first choice in people's fast-paced life. With the continuous innovation of technology and the rise of new retail industry, the field of plastic packaging will again usher in a blowout, and major enterprises at home and abroad have made countermeasures in the field of packaging.

High stiffness thermoplastic polypropylene packaging film is widely used in food packaging, drug packaging and other fields. At present, the domestic hot forming special materials mainly rely on imports, and a few domestic processing enterprises use two or three kinds of polypropylene resin mixed production according to a certain proportion, but the processing is difficult and the quality fluctuates greatly.

Current application status of thermoplastic packaging

At present, "high barrier plastic" is not used in low-end plastic packaging. When heating or placing hot food, toxic substances will be decomposed, and plasticizer is one of them. Plasticizers (plasticizers) are bulk industrial products, which are widely used in various fields of the national economy, including household goods such as preservative film, plastic bags, plastic edible oil barrels and so on.

Plasticizer is a kind of polymer auxiliary, and it is also a kind of phthalate esters in environmental estrogens. There are many kinds of plasticizers, and DEHP (commercial name DOP) is the most common one. The function of plasticizer is similar to that of artificial hormone, which can harm male reproductive ability and promote female precocious puberty; Because children are in the development period of endocrine system and reproductive system, the potential harm to children will be greater.

Therefore, the state in maintaining the safety of food plastic packaging continues to increase management efforts. Recently, the food safety office of the State Council and other 14 departments jointly issued a document requiring catering enterprises not to use plastic products containing plasticizers to store oils and fats. This measure indirectly promotes the rapid development of "high barrier plastic" packaging industry.

According to the global market insight report (GMI), in addition to protecting food from deterioration, food packaging manufacturers also use it as a sales promotion tool. This change has greatly increased the market scale of high barrier bags. In developing countries, the change of public life style and the increase of disposable income promote the market growth. The technological progress in product design, the prevention of water loss and the preservation of product freshness are the main factors contributing to the high demand of high barrier bags.

While pursuing high quality life, people are more willing to choose products that are beneficial to environment and health. Thermoforming "high barrier plastics" will become a guide for the development of packaging companies.
