Description
Technical field
It the utility model is related to plastic film material field, and in particular to a kind of tear-proof film.
Background technology
With the adjustment of expanding economy, Chinese all trades and professions constantly rise the market demand of plastic film.China's modeling
Material film industry is in a booming stage, it is reported that, the demand of Chinese Plastics film is every year by with more than 9%
Speed increases.And as various new materials, new equipment and new process constantly emerge in large numbers, will promote China plastic film towards
Diversification of varieties, customizations and possess multi-functional composite membrane direction and develop, can be used for packing, isolate, vacuum forming etc.
Field, so, existing film tearing toughness are poor, are difficult to play good effect in specific field.
Utility model content
（One）Technical problems to be solved
Problem to be solved in the utility model is to provide a kind of tear-proof film, improves tearing strength, improves product quality.
（Two）Technical solution
To solve the technical problem, the utility model provides a kind of tear-proof film, it is characterised in that the film bag
At least four-layer structure is included, PE film layers, nylon film layer, PP film layers and PE film layers is followed successively by from top to bottom, is set on the film
There are aperture, the elongated either triangle of the aperture or circle.
Further, EPDM film layers, the EPDM film layers, PE film layers, nylon film layer, PP films are additionally provided with the PE film layers
Bonding connection is carried out by glue-line between layer and PE film layers.
Further, the glue-line is modified binder resin for HDPE binder resins or EVA.
Further, the thickness of the PE film layers is 0.01 ~ 0.015mm, the thickness of the nylon film layer for 0.01 ~
0.014mm, the thickness of the PP film layers is 0.012 ~ 0.015mm, and the thickness of the EPDM film layers is 0.015 ~ 0.019mm.
（Three）Beneficial effect
A kind of tear-proof film provided by the utility model, has sandwich construction, suitable for the isolation film of assisted demoulding,
It is provided with through hole on isolation film, through hole makes in vacuum forming resin have a more preferable trafficability performance, and the design of through-hole structure,
Its trafficability performance and gas permeability are further increased, release cloth is easily torn not damaged, can also make product surface
It is more smooth, the quality of product is effectively improved, by the PE layers of setting, PP layers, nylon and EPDM layers, to ensure isolation film
Tear resistance, stripping result is improved while product quality is improved.
Brief description of the drawings
