Problems solved by technology

At present, the food plastic packaging containers in the domestic market mostly use polypropylene as raw material in the formula. Polypropylene is refined through 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 modified environment-friendly high molecular environment-friendly sheet which is prepared from the following components in percentage by mass: 50-55% of grade leveltalc powder, 30-35% of polypropylene resin, 12-15% of high density polyethylene and 2% of a dyeing agent. The formula not only can ensure high-temperature resistance, but also ensure the portability,flexibility and degradability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a formula for a modified environmentally friendly polymer environmental protection sheet. 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 "one order and three documents", the disposable foam plastic tableware will withdraw from the stage of history as soon as possible, which reminds people to pay more attention to the safety and environmental protection of food packaging containers. The quality of environmentally friendly tableware is determined by two factors: formula and process. At present, the food pl...
