Abstract

The invention belongs to the technical field of bio-based degradation, and particularly relates to an oxidative biodegradable microwave sterilization vacuum film. The oxidative biodegradable microwavesterilization vacuum film comprises a surface layer, a middle layer and an inner layer. The surface layer comprises a surface resin layer and a surface additive layer, the surface resin layer is modified polyvinyl alcohol (SHQ-MVA) resin, and the surface additive layer is an oxygen-containing polyolefin controlled degradation (HYZJ) additive. The middle layer comprises a middle resin layer and amiddle additive layer, the middle additive layer is located on the lower side of the middle resin layer, the middle resin layer is modified polybutylene succinate (SHQ-MBS) resin, and the middle additive layer is an oxidative biological controlled degradation (YHZJ) additive. The inner layer comprises an inner resin layer and an inner additive layer, the inner additive layer is located on the lower side of the inner resin layer, the inner resin layer is modified polycaprolactone (SHQ-MCL) resin, and the inner additive layer is a quintuple controlled degradation (WCZJ) additive.

Description

technical field [0001] The invention belongs to the technical field of bio-based degradation, and in particular relates to an oxidative biodegradable microwave sterilization vacuum film. Background technique [0002] With the rapid development of the economy, people's damage to the environment is becoming more and more serious, especially non-degradable plastics, which are not easy to be degraded by soil microorganisms after being randomly thrown away by people, remain in the soil for a long time, causing serious pollution to the ecological environment . Disposable tableware, disposable plastic products and agricultural mulch are difficult to recycle, and the traditional treatment methods are mainly incineration and landfill. Incineration will produce a large amount of harmful gas, which pollutes the environment; burial means that the polymers in it cannot be decomposed by microorganisms in a short time, which also pollutes the environment. The residual plastic film exists...
