Abstract
The utility model relates to an easily-torn film with a high insulation property, which is characterized in that the easily-torn film comprises seven layers of coextrusion films which are sequentially a polyethylene layer (1), a first bonding layer (2), a first nylon layer (3), an ethylene vinyl alcohol (EVOH) layer (4), a second nylon layer (5), a second bonding layer (6) and a polybutylene layer (7) from top to bottom. The easily-torn film with a high insulation property has good insulation property, can better protect contents from deterioration and can be easily torn off.
Description
Technical field
The utility model relates to a kind of high-barrier and easily takes off film, is mainly used in food, drug bottle packaging container seal package.
Background technology
At present, food, drug bottle packaging container seal the In Aluminium Foil Packings that adopt more, and it will adopt the mode of adhesive bonding to seal with the bowl body, is difficult for opening, and needs to use handle, backguy, draw ring etc.; Adhesive easily enters in food, the medicine, and it is rotten that it is taken place, and influences its security performance.When container is a plastic bowl, and when needing deepfreeze, the aluminium foil shrinkage factor is big, and easily making influences the obstruction seals performance by a bowl body deformability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of good barrier property, content high-barrier not perishable, that open easily easily to take off film.
The purpose of this utility model is achieved in that a kind of high-barrier easily takes off film, the described film of easily taking off is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: polyethylene layer, first adhesive layer, first nylon layer, evoh layer, second nylon layer, second adhesive layer and polybutene layer.
The beneficial effect that the utility model high-barrier is easily taken off film is:
The utility model was made of seven stacked adding, and by having complementary functions between the different plastic layers, improved its combination property;
Polyethylene layer, raising is endured property, is prevented to curl, and can be used for high-speed packaging, has moisture barrier property, and the surface is easy to printing;
First nylon layer and second nylon layer strengthen mechanical property, improve the stretch-proof ability, and gases such as oxygen are had certain barrier, are secondary barrier layer;
Evoh layer has stronger barrier to gases such as oxygen, is main barrier layer;
The polybutene layer is suitable for low-temperature heat-sealing, and is easy to open;
First adhesive layer and second adhesive layer can well be bonded together the bad material of adjacent two kinds of compatibilities, are difficult for delamination, are easy to co-extrusion modling.
In sum, the utility model high-barrier is easily taken off film, and good barrier property, content be not perishable, open easily.
Description of drawings
A kind of high-barrier that Fig. 1 relates to for the utility model is easily taken off the section structure schematic diagram of film.
Among the figure:
Polyethylene layer 1, first adhesive layer 2, first nylon layer 3, evoh layer 4, second nylon layer 5, second adhesive layer 6, polybutene layer 7.
The specific embodiment
Referring to Fig. 1, a kind of high-barrier that the utility model relates to is easily taken off film, the described film of easily taking off is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: polyethylene (PE) layer 1, first adhesive layer 2, first nylon (PA) layer 3, evoh layer 4, second nylon (PA) layer, 5, second adhesive layer 6, polybutene (PB) layer 7.
First adhesive layer 2 and second adhesive layer 6 adopt the TIE of du pont company.
Claims (1)
1. a high-barrier is easily taken off film, it is characterized in that: the described film of easily taking off is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: polyethylene layer (1), first adhesive layer (2), first nylon layer (3), evoh layer (4), second nylon layer (5), second adhesive layer (6) and polybutene layer (7).
