Problems solved by technology

[0004] ① When end customers use POF shrink film, in order to improve packaging efficiency, they adopt higher-speed packaging equipment. After the speed is increased, the traditional POF film will shrink incompletely, and the packaged items will be loose and not fit
[0005] ② Some heavier and larger items may be damaged or torn during packaging
[0006] ③Because the packaging equipment runs too fast, the seal will not be firm, damaged and cracked

Embodiment Construction

[0039] Such as figure 1 As shown, a method of using resin POE in POF polyolefin shrink film, including raw material ratio and process flow:

[0040] The application technology of a new resin POE in POF polyolefin shrink film, its raw material ratio includes the raw material ratio of the upper and lower surface layers, the raw material ratio of the middle layer and the ratio of processing aids. The raw material ratio of the upper and lower surface layers is POE10%, ternary random copolymer polypropylene 25%, the raw material ratio of the middle layer is eight carbon linear low density polyethylene 45%, ultra low density polyethylene 18%, processing aid 2 %.

[0041] A kind of method that resin POE is applied in POF polyolefin shrinkage film, its technological process is:

[0042] 1. Select raw materials

[0043] Select POE, ternary random copolymer, eight-carbon linear low-density polyethylene, ultra-low-density polyethylene and processing aids, the mass percentage of which ...

Abstract

The purpose of the present invention is to overcome the defects of traditional POF film products, improve the performance of traditional POF film products, and provide a method for applying resin POE in POF polyolefin shrink film that can improve the performance of traditional POF film products, including raw material ratio and process flow. The ratio of raw materials includes the ratio of raw materials for the upper and lower surface layers, the ratio of raw materials for the middle layer and the ratio of processing aids. The raw material ratio of the upper and lower surface layers is POE10%, ternary random copolymer polypropylene 25%, the raw material ratio of the middle layer is eight carbon linear low density polyethylene 45%, ultra low density polyethylene 18%, processing aid 2 %. The process flow is: selection of raw materials, plasticizing extrusion, film tube shaping, bidirectional stretching, film bubble inflation, heat setting treatment, product cooling, and winding.

Description

Technical field: [0001] The invention relates to a method for applying resin POE to POF polyolefin shrink film, and belongs to the technical field of plastic heat shrinkable film flexible packaging. Background technique: [0002] 1. POF environment-friendly polyolefin shrink film is a new type of plastic packaging material developed in Italy in the 1990s. It has the international advanced level. It is processed by special processes such as mold head molding and film bubble inflation. The product is natural, non-toxic and environmentally friendly, and meets US FDA and USDA standards. It will not release toxic gases during heat sealing, waste can be recycled, and has high transparency. High shrinkage rate, good heat sealing performance, suitable for automatic packaging machines, it is an updated product of traditional PVC shrink film. [0003] 2. With the development of the times and the development of industrialization, some deficiencies and defects of traditional POF polyol...
