Thermoplastic multiple degradable materials and its products producing process

Abstract

A degradable multi-element thermoplastic material used for preparing the expendable food containers contains starch, resin, plant oil, biodegradant, photodegradation promoter, ultraviolet absorbent and saponified transition metal. Said expandable food container is prepared from said components through proportional mixing, heating, extruding out shaping, cooling and punching. Its advantages are easy degradation, and no leakage and pollution.

Description

technical field [0001] The invention relates to a material and a process for manufacturing food packaging containers. Background technique [0002] The extensive use of plastic products has greatly facilitated people's lives, and the ensuing negative impact cannot be ignored. Plastic products such as plastic film, shopping bags, disposable foam lunch boxes, and noodle bowls can be seen everywhere in rivers, lakes, cities and villages. Because of their non-degradability, shocking "white pollution" is caused, which poses a serious threat to the living environment of human beings. Local governments have issued regulations restricting the use of single-use cutlery, and over time, cutlery made of this material will be banned entirely. Disposable tableware has the advantages of convenience and hygiene, adapts to modern fast-paced life, and is also necessary for life. It is forbidden to use it to cause inconvenience to people's work and life. Therefore, t...
