Problems solved by technology

The food plastic packaging containers provided by the prior art often use polypropylene as the raw material in the formula. Polypropylene is refined from petroleum. If the content of polypropylene is too high, it will increase the import of petroleum, waste energy and increase production costs. , if the polypropylene content is too low, the final product will have high quality and high brittleness, which does not meet the requirements of light weight disposable tableware

Abstract

The invention provides a formula of a polypropylene composite material. The polypropylene composite material comprises, by mass, 65-70% of food-grade talcum powder, 26 to 31% of polypropylene and 4% of polyethylene glycol. The polypropylene composite material has advantages of light weight and high temperature resistance of a polypropylene material. Through the food-grade talcum powder, hardness, degradability and flexibility of a food package container prepared according to the formula are improved. In burning of the polypropylene composite material, poison gas dioxins are avoided and recovery utilization is realized so that environmental protection is realized.

Description

technical field [0001] The invention relates to the technical field of raw materials for environment-friendly food plastic packaging containers, in particular to a formula of a polypropylene composite material. Background technique [0002] With the continuous improvement of people's living standards, especially the frequent occurrence of food safety accidents, consumers' requirements for food packaging containers are not only limited to their convenience and speed, but also to the quality and safety performance requirements of packaging containers and materials. More stringent, especially with the release of the national plastic ban order, it has reminded people to pay more attention to the safety and environmental protection of food packaging containers. The food plastic packaging containers provided by the prior art often use polypropylene as the raw material in the formula. Polypropylene is refined from petroleum. If the content of polypropylene is too high, it will incr...
