Problems solved by technology

[0003] For the multi-layer co-extruded packaging film, it has a multi-layer structure composed of polyethylene, polypropylene, nylon, adhesive resin and other materials. In order to make the packaging film have high transparency, first of all, each material of the packaging film must be It has good transparency, otherwise the transparency of the packaging film composed of multiple layers will be greatly reduced

Abstract

The invention provides an adhesive resin for a high-transparency packaging film. The adhesive resin comprises the following components in parts by weight: 20-60 parts of low-density polyethylene, 10-40 parts of modified low-density polyethylene, 10-30 parts of a polyethylene elastomer, 1-10 parts of a nucleating agent and 0.1-3 parts of a stabilizer. The invention also provides a preparation method of the adhesive resin for the high-transparency packaging film. The adhesive resin for the high-transparency packaging film, which is prepared by mixing the low-density polyethylene, the modified low-density polyethylene, the polyethylene elastomer, the nucleating agent and the stabilizer according to specified parts by weight and then carrying out processing, has high transparency, can be applied to production of the high-transparency packaging film, overcomes problems in the transparency of the packaging films and improves the use performance of the packaging film.

Description

technical field [0001] The invention relates to the field of adhesive resins, in particular to an adhesive resin for highly transparent packaging films and a preparation method thereof. Background technique [0002] As a consumer product that is closely related to people's lives, packaging film is ubiquitous in our lives and has become an indispensable material in the field of consumer products today. One of the most important advantages of the packaging film is its transparency, which is not only suitable for packaging products of various shapes, but also can observe the product itself through the packaging film, which not only increases the attractiveness of the product appearance, but also makes the product appearance beautiful and clean. beautiful. [0003] For the multi-layer co-extruded packaging film, it has a multi-layer structure composed of polyethylene, polypropylene, nylon, adhesive resin and other materials. In order to make the packaging film have high transpa...
