Abstract

The invention relates to a polyethylene packaging compounding additive that could improve the physical capability of polyethylene. The constituents are 10-30% silicide, 20-40%stearamide, 5-25% antioxidant, 10-22% antistatic agent, and 10-22% zinc stearate. The invention could keep the diaphaneity of polyethylene and could make the film has the function of sliding and high efficiency anti oxygen and antistatic.

Description

technical field [0001] The invention relates to the field of polyethylene, in particular to additives for improving some physical properties of polyethylene films. Background technique [0002] The use of polyethylene packaging film has been on the market for a long time, and it has a wide range of applications. This is because it is convenient to use, low in cost, and highly optional in processing. Therefore, it is the preferred material for various commodity manufacturers. The manufacturing process of the polyethylene packaging film is to extrude the polyethylene rubber particles under the condition of heating when they pass through the pressure roller. In general, after extrusion, the inner wall of the rubber tube is tightly adhered to each other. After being continuously extruded by atmospheric pressure, the two layers of film will be bonded, making it difficult to open the film. In order to solve this problem, some manufacturers began to find some additives added to pol...
