Problems solved by technology

However, while starch improves the degradability of plastics, on the one hand, it will cause a decrease in its physical and mechanical properties, making it difficult to process. On the other hand, it is also too hydrophilic, which is not compatible with most general-purpose resins. Poor, resulting in a significant decline in the mechanical properties of the film, poor water resistance, thus hindering the wide application of starch plastics in the process of industrialization
PVC resin is a widely used high molecular polymer, its performance is between plastic and rubber, it contains a large number of polar hydroxyl

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a starch-PVC resin blended fully degradable bone sticking bag and a preparation method thereof. Background technique [0002] In recent years, due to the increasingly serious "white pollution" caused by waste plastics that are difficult to degrade, it has attracted widespread attention from all over the world. Countries around the world have successively issued relevant laws and regulations restricting or prohibiting the use of non-degradable plastic packaging. On the other hand, because petroleum, the raw material for making traditional plastics, is a non-renewable resource, it will be exhausted with the massive use of human beings. Therefore, it is imminent to develop environmentally friendly plastics that use renewable resources as raw materials and are degradable. [0003] The use of biodegradable starch materials to prepare degradable packaging films has become a resea...
