Antibacterial, deodorizing polyester biodegradable food rolling bag as well as preparation and application of rolling bag

Abstract

The invention discloses an antibacterial, deodorizing polyester biodegradable food rolling bag. The packaging for cooked food and fresh meat is prepared by carrying out chain extension and modification on copolyester prepared from an aromatic dicarboxylic acid as well as an aliphatic dicarboxylic acid and a dibastic alcohol, has the advantages of antibacterial and deodorizing effects, excellent performance, high molecular weight, high degree of branching, high crystallinity and low content of impurities and is non-toxic and can be biodegradable after the packaging is abandoned.

Description

technical field [0001] The invention relates to a polymer, in particular to an antibacterial and odor-removing polyester biodegradable food roll bag and its preparation and application. Background technique [0002] Due to the implementation of the "Plastic Restriction Order", the use of plastic shopping bags has dropped significantly due to the start of charges, while the use of plastic roll bags provided free of charge in supermarkets has begun to increase. Some customers use roll bags to pack cooked food and fresh meat, but experts say that the roll bags used in supermarkets generally do not have any markings or QS marks.

At present, many roll bags are directly used to hold food, but there is no word "for food", so it is difficult to know whether the material and production requirements can me...

AI Technical Summary

Problems solved by technology

At present, many roll bags are directly used to hold food, but there is no word "for food", so it is difficult to know whether the material and production requirements can meet the requirements for food, and whether it is safe

Therefore, the roll bag cannot be completely equivalent to the food bag

In addition, the abuse of tear-off bags by some consumers is contrary to the environmental protection concept advocated by the state, which will cause new waste of resources and pollution.
