Abstract

The invention discloses a degradable double-layer plastic express bag and a preparation method thereof. The express bag comprises an outer layer bag body and an inner layer bag body, wherein, in mass percentage, the outer layer bag body comprises the following components: 10-30% of LDPE, 50-80% of LLPDE and 10-30% of white master batches, and the inner bag body comprises the following components: 10-30% of LDPE, 50-80% of LLPDE, 1-5% of black master batches, 1-5% of an anti-block agent, and 2-4% of EPI. In the express bag, the EPI is a completely biodegradable plastic additive, and has a characteristic of oxidizing plastics so as to achieve the function of degrading the plastics and solve the white pollution problem caused by the plastics.

Description

technical field [0001] The invention relates to the field of express bag preparation, in particular to a degradable double-layer plastic express bag and a preparation method thereof. Background technique [0002] Plastic is sometimes widely used in various fields because of its light weight and low price. As a rapidly developing industry, the logistics express transportation industry, its plastic express bags make people's work and life more convenient, so it is even more important favored. However, the extensive use of plastics has caused increasingly serious "white pollution" to the environment, which has become a worldwide public hazard. [0003] In response to this kind of pollution, the proposed degradable plastic is undoubtedly one of the necessary ways to achieve environmental sustainable development. Contents of the invention [0004] The problem to be solved by the present invention is to provide a degradable double-layer plastic express bag with low preparation...
