Abstract

The invention especially relates to a bio-based high-barrier multilayer co-extruded blown film, belonging to the field of bio-based degradation technology. The bio-based high-barrier multilayer co-extruded blown film comprises a surface layer, a middle layer and an inner layer, wherein the surface layer comprises a surface resin layer and a surface additive layer; the surface resin layer is sextuple controllable degradation (LCSZ) resin, and the surface additive layer is an environmentally controllable degradation (HJZJ) additive; the middle layer comprises a middle resin layer and a middle additive layer; the middle additive layer is located below the middle resin layer, the middle resin layer is modified polypropylene carbonate (SHQ-MPC) resin, and the middle additive layer is an oxidizing bio-based controllable degradation (YSZJ) additive; the inner layer includes an inner resin layer and an inner additive layer; and the inner additive layer is located below the inner resin layer, the inner resin layer is modified bio-based polyolefin bonding (SHQ-MTIE) resin, and the inner additive layer is a water-retaining controllable degradation (BSZJ) additive.

Description

Technical field [0001] The invention belongs to the technical field of bio-based degradation, and particularly relates to a bio-based high barrier multi-layer co-extruded bio-based blown film. Background technique [0002] With the rapid economic development, people are increasingly destroying the environment, especially non-degradable plastics, which are not easily degraded by soil microorganisms after they are randomly thrown away by people, and they 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 traditional treatment methods are mainly incineration and burying. Incineration will produce a large amount of harmful gases and pollute the environment; while buried, the polymer in it cannot be decomposed by microorganisms in a short time, which also pollutes the environment. The discarded plastic film exists in the soil, hindering ...
