In recent years, food safety incidents caused by food plastic packaging quality problems occur from time to time. In order to ensure food safety, it is necessary to put forward higher quality requirements for food plastic packaging products to prevent food from secondary pollution.
Plastic packaging used for food must have proper barrier property, such as high oxygen resistance and oil resistance for fat food, high moisture resistance for dry food, high resistance to odor for aromatic food, and oxygen, carbon dioxide and water vapor permeability for fruit and vegetable fresh food.
At the same time, food plastic packaging should have good mechanical properties, mainly including the tensile strength, tear resistance, impact resistance, etc.; it should have good chemical stability, and should not have any chemical reaction with the inner food to ensure food safety. In addition, plastic food packaging should have high temperature resistance, suitable for high temperature disinfection and low temperature storage of food.
At present, in many food packaging materials, plastic products and composite packaging materials play an important role. However, due to the defects of plastic materials, such as environmental pollution, its temperature resistance and barrier properties are not as good as metal and glass containers.
Therefore, the rapid development of food industry has put forward new issues to the chemical industry, especially the plastic products industry. This is to improve the properties of existing plastics, develop new varieties, improve their strength and barrier properties, and reduce the amount (thick wall); at the same time, it should be easy to reuse, classify and recycle, so as to protect the environment.
According to Professor Lei Jingxin, an authoritative expert in the field of polymer materials, at present, more than 90% of PVC soft products in China still use traditional phthalate plasticizers. If the current situation of PVC plastic products is not completely changed, the "plasticizer event" of liquor will appear, and even beer, drinks, moon cakes and various food seasonings, such as soy sauce, vinegar, medical infusion set and blood transfusion bag, are toxic The occurrence of plasticizer exceeding the standard is not accidental, but inevitable.
It is precisely because of the abuse of o-benzene plasticizer that we can hardly find "clean and non-toxic" plastic products in our lives, which is not alarmist.
Professor Lei Jingxin said that in fact, it is not difficult to produce non-toxic PVC plastic products. The non-toxic PVC plastic products can be prepared by adding non-toxic environmental plasticizer, calcium zinc stabilizer and other non-toxic processing aids.
Food industry is a sunrise industry in the 21st century, but with the continuous improvement of people's life quality and increasing attention to health consumption, there will be higher requirements for the quality and safety of food. Accordingly, the field of food packaging materials will also usher in huge development space and development potential.
