Low-gram-weight and high-performance PE (Poly Ethylene) embossing film and manufacturing technology thereof

Abstract

A low-gram-weight and high-performance PE embossing film is characterized in that the embossing film comprises three layers of films formed through co-extrusion; the surface of the embossing film is subjected to corona treatment; the components and the weight percentage of the three film layers are as follows: a first layer comprises the components in percentage by weight as follows: 85%-95% of m LLDPE (linear low density polyethylene) and 5%-15% of color masterbatch; a second layer comprises the components in percentage by weight as follows: 85%-95% of HDPE (high-density polyethylene) and 5%-15% of color masterbatch; and a third layer comprises the components in percentage by weight as follows: 83%-93% of LDPE (low-density polyethylene), 5%-15% of color masterbatch and 1%-2% of a slipping agent. According to the low-gram-weight and high-performance PE embossing film, the material of the slipping agent in a certain proportion is added to the formula and subjected to co-mixing with the LDPE, the friction coefficient of the film surface is reduced, the adhesion problem among films is eliminated, and the texture is more smooth; good co-mixing and plasticizing effects of the materials are guaranteed by the aid of a three-layer co-extrusion casting technology, and the problems that the co-mixing effect of a conventional single-layer co-extrusion technology is poor, and the plasticizing is not good are solved; and the die head gap is controlled through the system and the flow of a molten plastic fluid is controlled through a metering pump, so that the film casting stable linear extrusion is realized.

Description

technical field [0001] The invention relates to a PE embossed film and a production process thereof, in particular to a low-weight high-performance PE embossed film and a production process thereof. Background technique [0002] PE embossed film can prevent the penetration of liquid, has the function of anti-permeation and anti-pollution, soft and comfortable, and has a high-grade paper effect in appearance, so it is widely used in women's sanitary napkins, sanitary pads, baby diapers, adult incontinence Production of leak-proof layers for supplies, disposable medical and industrial protective supplies such as surgical gowns and shoe covers. [0003] According to statistics, in 2011, the output of adult paper diapers in my country was about 937 million pieces, the export volume was about 237 million pieces, and the consumption volume was about 631 million pieces; the total market size of sanitary napkins and sanitary pads was about 26.28 billion yuan, an increase of 7.9% ove...

AI Technical Summary

Problems solved by technology

[0005] At present, domestic manufacturers have produced low-weight PE embossed films. However, the low-weight PE embossed films produced by domestic manufacturers generally suffer from weight loss and physical properties of the products. Unfavorable phenomena such as "bones and tendons" are prone to occur after winding

High-performance low-weight PE embossed film still mainly relies on imports, so to a certain extent, it increases the manufacturing cost of high-quality disposable sanitary products, disposable medical protective products and industrial protective products
