Abstract

The invention discloses a high-temperature resistance food preserving film. The film is prepared from the following raw materials in parts by weight: 52-74 parts of phenolic resin, 15-28 parts of sisal hemp leaves, 15-28 parts of crape myrtle petals, 13-26 parts of Pulullan, 3-6 parts of flame retardant and 2-5 parts of an emulsifier. The food preserving film can be used for effectively inhibitingbacterium growth and prolonging the food storage time, has ultralow heat shrinkage rate and relatively high tensile strength, is safe and reliable to use, and has a wide market prospect.

Description

technical field [0001] The invention relates to the scope of food preservation, in particular to a high temperature resistant food preservation film and a preparation method thereof. Background technique [0002] Cling film is a kind of plastic packaging product, which is usually made of ethylene as the masterbatch through polymerization reaction. Cling film can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC ; The third is polyvinylidene chloride, referred to as PVDC. Microwave food heating, refrigerator food preservation, fresh and cooked food packaging and other occasions are widely used in family life, supermarkets, hotels and restaurants, and food packaging in industrial production. [0003] The performance of traditional plastic wraps in terms of high temperature resistance is mostly unsatisfactory, and the reliability and safety of use are low. At the same time, the antibacterial eff...
