Abstract

The invention discloses an environment-friendly plastic for a flexible packaging material. The environment-friendly plastic comprises the following raw materials in parts by weight: 100-120 parts of a base material, 1-1.5 parts of 4, 4-bis-(t-butylperoxy) butyl pentanoate, 0.4-0.8 part of dibutyltin dilaurate, 2-2.8 parts of 1, 1-bis-(t-butylperoxy) cyclohexane, 50-60 parts of a filling material, 4-8 parts of epoxidized soybean oil, 1.5-2.5 parts of calcium stearate, 1.6-1.8 parts of zinc stearate, 5-7 parts of hydroxyl silicone oil, 0.5-1.5 parts of an antioxidant, 1-2 parts of an ultraviolet absorber, 1-2 parts of a dispersing agent and 0.5-1.3 parts of a light stabilizer. The environment-friendly plastic uses environment-friendly biodegradable polylactic resin; through the optimization of a mixture ratio of raw materials, the strength, the toughness and the heat resistance of the environment-friendly plastic are improved; the production cost is reduced; the environment-friendly plastic can replace general plastic and can protect the environment better.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an environment-friendly plastic for soft packaging materials. Background technique [0002] With the continuous development of science and technology, resources and energy are increasingly tense, and environmental problems will become more prominent. Although plastic flexible packaging materials are developing rapidly at present, they are also facing severe challenges. In the future, plastic bag products will not only meet the increasing technical requirements for packaging quality and efficiency of different products, but also require them to be developed with resource-saving and energy-saving technologies. The starting point is to realize the development of high performance, multi-function, environmental protection and broaden the application field of the plastic bag industry. At present, my country's environmentally friendly plastic products have weak toughness and poor heat...
