Problems solved by technology

[0003] However, the film used on PE mattresses currently on the market has poor viscosity due to its own material limitations, and the adhesion between the films squeezed together when the mattress is rolled is not enough, which greatly increases the The volume of the mattress after rolling, and most of the films have poor explosion-proof performance, and they are easy to break when rolling, and during transportation, due to logistics and other reasons, the mattress will be dragged around, and the film Poor wear resistance, easy to damage the mattress

Abstract

The invention discloses a rolling and packing film applied to a PE mattress and a preparation method. The raw material components of the rolling and packing film applied to the PE mattress are as follows: 280-320 parts of high density polyethylene, 290-310 parts of low density polyethylene, 90-110 parts of metallocene, 140-160 parts of linear materials and 40-60 parts of viscous agent in parts byweight, wherein the density range of the high density polyethylene is 0.93-0.94 g / cm3, and the density range of the low density polyethylene is 0.92-0.93 g / cm3; and therefore, the rolling and packingfilm manufactured by using the formula has the advantages of high adhesiveness, excellent explosion-proof performance and excellent wear-resisting property.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a rolling film applied to a PE mattress and a preparation method for preparing the rolling film. Background technique [0002] With the improvement of people's living standards, various products have appeared in the field of mattresses. Among them, in order to solve the problem of inconvenient transportation caused by the excessive size of mattresses, people have invented the use of related equipment to compress mattresses in rolls. In order to solve the above problems, during the compression process, a layer of film is usually put on the surface of the mattress to protect the mattress. Among them, the film is the most widely used on PE mattresses. [0003] However, the film used on PE mattresses currently on the market has poor viscosity due to its own material limitations, and the adhesion between the films squeezed together when the mattress is rolled is not enough, which gre...
