Abstract

The invention relates to an ultra-thin PE (polyethylene) film for a packaging bag. The ultra-thin PE film comprises components in parts by mass as follows: 20-40 parts of EVA (ethylene vinyl acetate) FL0014, 10-30 parts of MLLDPE (metallocene linear low-density polyethylene) 1018 FA, 30-40 parts of linear HDPE (linear high-density polyethylene) 2045Q, 20-35 parts of HDPE LD100AC, 0.5-1.0 part of a slipping agent and 0.2-0.8 parts of an antioxidant. The ultra-thin PE film has the advantages that linear grains in a production process of the film are eliminated, the film has better heat sealing property and ageing resistance, the tensile strength is higher than the national standard by 20%, and the shelf life of the film is prolonged by 6-8 months than the conventional products.

Description

The ultrathin PE film of a kind of packing bag
Technical field
The invention belongs to plastics film technical field, what relate to is the ultrathin PE film of a kind of packing bag.
Background technology
Packing bag is a kind of multi-layer compound structure, along with the difference of packing bag application, the difference of volume, multilayered structure also can change thereupon, plastic film is the one deck in multi-layer compound structure, simultaneously, plastic film also can be used alone, be widely used in packaging field, at present, widely, be mainly used in the interior adventitia of food pack, the production technique of plastic film mainly includes in the application of thin plastic film: raw material is weighed, the metering of various raw material is stirred, feed intake, melt extrude, shaping film and cooling, draw, cut and batch.But in the production of thin plastic film, also there is a lot of problem, affect the shaping of product and quality, 1, thin plastic film processing difficulties, melt fracture is serious, and the linear line of generation is difficult to eliminate, and 2, because film temperature is high, therefore towing mechanism must install the normal production of cooling roller ability additional, and 3, the film clarity produced is poor, the problems referred to above not only need the improvement of production technique, the more important thing is choosing and proportioning of raw material.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and propose the ultrathin PE film of a kind of packing bag.
The present invention solves its technical problem and takes following technical scheme to realize:
The ultrathin PE film of a kind of packing bag, comprises by the following component of massfraction than formation:
And, in above-mentioned component, include 0.2 part-0.8 part, the oxidation inhibitor added by massfraction further.
And described slipping agent is the one in amine hydroxybenzene class slipping agent or erucicamide class slipping agent.
And the concrete model of slipping agent is: ESQ-4; The concrete model of oxidation inhibitor is: 501.
Advantage of the present invention and positively effect are:
1, this invention removes the linear line produced in process of producing product;
2, proportioning raw materials of the present invention makes towing mechanism aborning not need cooling roller to produce;
3, the ultrathin PE film that proportioning raw materials of the present invention is produced has better ageing resistance, and the quality guaranteed period of film extends 6-8 month than current product;
4, the ultrathin PE film that the present invention produces has better heat sealability, and tensile strength is higher than GB 20%, and fall down test is better than current product.
Embodiment
Be further described the invention process below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
The ultrathin PE film of a kind of packing bag, comprises by the following component of massfraction than formation:
Wherein, slipping agent is amine hydroxybenzene, the one in erucicamide; Concrete model is: ESQ-4;
In specific embodiment of the invention, be added with the oxidation inhibitor of 0.2 part-0.8 part in said components further, the concrete model of oxidation inhibitor may be selected to be: 501:
By above-mentioned by massfraction than the component formed according to technological process: raw material is weighed, the metering of various raw material is stirred, feed intake, melt extrude, shaping film and cooling, draw, cut and batch, and can produce ultrathin PE film.
Example one
The ultrathin PE film of a kind of packing bag, comprises by the following component of massfraction than formation:
By above-mentioned by massfraction than the component formed according to technological process: raw material is weighed, the metering of various raw material is stirred, feed intake, melt extrude, shaping film and cooling, draw, cut and batch, ultrathin PE film can be produced, our experiments show that, this ultrathin PE film only has when 80% of current plastic film thickness at thickness still can keep identical physical and chemical index, there is the better transparency simultaneously, there is no linear line.
Example two
The ultrathin PE film of a kind of packing bag, comprises by the following component of massfraction than formation:
By above-mentioned by massfraction than the component formed according to technological process: raw material is weighed, the metering of various raw material is stirred, feed intake, melt extrude, shaping film and cooling, draw, cut and batch, and can produce ultrathin PE film.Our experiments show that, this ultrathin PE film only has when 80% of current plastic film thickness at thickness can keep identical physical and chemical index equally, has the better transparency simultaneously, does not have linear line.
Example three
The ultrathin PE film of a kind of packing bag, comprises by the following component of massfraction than formation:
By above-mentioned by massfraction than the component formed according to technological process: raw material is weighed, the metering of various raw material is stirred, feed intake, melt extrude, shaping film and cooling, draw, cut and batch, and can produce ultrathin PE film.Our experiments show that, this ultrathin PE film only has when 80% of current plastic film thickness at thickness can keep identical physical and chemical index equally, there is the better transparency simultaneously, there is no linear line, meet fall down test, tensile strength is higher than GB 20%, and the quality guaranteed period of film extends 6-8 month than current product.
