Embodiment Construction

[0024] An oxidative biodegradable food storage film, comprising a surface layer 1, a middle layer 2, and an inner layer 3;

[0025] The surface layer 1 includes a surface layer resin layer 4 and a surface layer additive layer 5. The surface layer additive layer 5 is located below the surface layer resin layer 4. The surface layer resin layer 4 is an oxygen-containing polyolefin controllable degradation (HYSZ) resin, and the surface layer additive layer 5 is PVA bio-based Controlled degradation (PVZJ) additive;

[0026] Middle layer 2 comprises middle layer resin layer 6, middle layer additive layer 7, middle layer additive layer 7 is positioned at the below of middle layer resin layer 6, middle layer resin layer 6 is modified polylactic acid (SHQ-MLA) resin, middle layer additive layer 7 is PBAT biological base can Degradation control (PBZJ) additive;

[0027] The inner layer 3 includes an inner layer resin layer 8 and an inner layer additive layer 9, the inner layer additive...

Description

technical field [0001] The invention belongs to the technical field of bio-based degradation, and in particular relates to an oxidative biodegradable food storage 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 in the soil, whic...
