Abstract

The invention relates to the cold drawing sleeving film. The cold drawing sleeving film comprises a core layer. The core layer is covered by a first surface layer. The first surface layer is covered with a second surface layer. By mass, the first surface layer and the second surface layer are independently selected from at least two of the following compositions of, by weight, 80 parts to 98 partsof metallocene ethylene and hexene copolymer, 30 parts to 60 parts of metallocene polyethylene, 30 parts to 60 parts of propylene-based elastomer, 5 parts to 10 parts of low-density polyethylene, 1 part to 2 parts of an opening agent, 1 part to 5 parts of cellulose, 2 part to 5 parts of titanium dioxide, and 1 part to 3 parts of silicone oil. By mass, the core layer comprises the following compositions of, by weight, 30 parts to 60 parts of propylene-based elastomer, 0 part to 60 parts of metallocene polyethylene, 10 parts to 40 parts of low-density polyethylene, 10 parts to 50 parts of high-density ethylene and vinyl acetate copolymer, 1 part to 5 parts of cellulose, 2 parts to 5 parts of titanium dioxide, and 2 parts to 4 parts of silicone oil. The propylene-based elastomer is composedof isotactic polypropylene and atactic polyethylene. The cold drawing sleeving film prepared with the compound is good in stretchability, resilience and puncture resistance.

Description

technical field [0001] The invention relates to a cold stretch hood, in particular to a composition for a cold stretch hood and the cold stretch hood. Background technique [0002] Stretch hood film is mainly suitable for the transportation of light and bulky goods. It plays the role of binding and fixing during transportation. It is convenient, simple and cost-saving, and can replace stretch film. Stretch hood film is also known as stretch cover or cold shrink film. The tube-shaped elastic plastic Zun heat-sealed at the top is stretched horizontally and horizontally at room temperature, and the upper part of the package is vertically covered and the elasticity is released at the bottom of the tray, so that it tightly wraps the product. [0003] CN103434152A discloses a cold-stretch film and its production method, CN110204824A discloses a polyolefin cold-stretch sleeve film and a preparation method thereof, and CN101439607A discloses a high-strength cold-shrink stretch slee...
