Full-biodegradable vest bag producing process

Abstract

The invention discloses a full- biodegradable vest bag producing process. The process includes the following steps of firstly, adding PBAT, PLA, thermoplastic resin, a chain extender, radix paeoniae alba, the root bark of the peony tree and filler into a high-speed mixer to be stirred and mixed to obtain a mixture; secondly, adding the mixture into a screw extruder to be extruded and mixed, and conducting cooling and granulating after extruding; thirdly, conducting blow molding on obtained granules through a blowing machine to form a composite thin film; fourthly, winding and collecting the composite thin film formed in the third step; fifthly, cutting the composite thin film collected in the fourth step through a roll-up bag machine to prepare roll-up vest bags. The toughness and antibacterial effects are enhanced, the bags can be degraded only after several months, and white pollution is effectively prevented.

Description

technical field [0001] The invention relates to a production process of a vest bag, in particular to a production process of a fully biodegradable vest bag. Background technique [0002] With the improvement of people's living standards, the concept of garbage bagging has gradually entered people's lives in recent years. The vest bag is a kind of garbage bag, shaped like a vest. At present, most of the vest bags used in the market are made of polyethylene or polyvinyl chloride raw materials. Due to the huge amount of such vest bags used and non-degradable, serious resource waste and environmental pollution have been caused. However, non-degradable vest bags will take hundreds of years to rot and seriously pollute the soil if they are buried in the ground. If incinerated, they will generate harmful smoke and toxic gases, polluting the environment for a long time, and have poor toughness and antibacterial effect. Contents of the invention [0003] The technical problem to ...

Problems solved by technology

At present, most of the vest bags used in the market are made of polyethylene or polyvinyl chloride raw materials. Due to the huge amount of this vest bag and its non-degradability, it has caused serious waste of resources and environmental pollution.

However, it takes hundreds of years for non-degradable vest bags to rot and seriously pollute the soil if buried in the ground. If incinerated, it will generate harmful smoke and toxic gases, pollute the environment for a long time, and have poor toughness and antibacterial effect
