Abstract
The utility model relates to a high-barrier multi-layer co-extrusion packaging film, which belongs to the technical field of food packaging materials and is characterized by comprising nine layers of co-extrusion films. The nine layers of co-extrusion films are sequentially a first nylon layer (1), a first adhesion layer (2), a first polyethylene layer (3), a second adhesion layer (4), a second nylon layer (5), an ethylene-co-vinyl alcohol (EVOH) layer (6), a third nylon layer (7), a third adhesion layer (8) and a second PE layer (9) from top to bottom. The high-barrier multi-layer co-extrusion packaging film has good barrier property, can prolong storage life of meat products and the contents in the packaging film are not easy to go bad.
Description
Technical field
The utility model relates to the multi-layer co-extruded packaging film of a kind of high-barrier.Be mainly used in the packing of meat products.Belong to the packaging material for food technical field.
Background technology
At present, the packing film of meat products need have oil resistance, block water, hinder high obstructing performance such as oxygen, to prolong the storage life of meat product.Conventional single thin film, its performance ratio is more single, barrier is poor, can not satisfy operating needs, as crossing the packing requirements to reach meat products, need adopt methods such as the compound or solvent of dry types is compound to realize through a plurality of single thin films, operation is many, cause the fringe cost height successively, the pollution to film and environment simultaneously is big, and sanitation performance is bad.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of high-barrier multi-layer co-extruded packaging film, the storage life that its good barrier property, content be not perishable, can prolong meat products.
The purpose of this utility model is achieved in that the multi-layer co-extruded packaging film of a kind of high-barrier, described packaging film is nine layers of coextruded film, and it is followed successively by from top to bottom: first nylon layer, first bonding coat, a PE layer, second bonding coat, second nylon layer, evoh layer, the 3rd nylon layer, the 3rd bonding coat and the 2nd PE layer.
The beneficial effect of the multi-layer co-extruded packaging film of the utility model high-barrier is:
The utility model was made of nine stacked adding, and by having complementary functions between the different plastic layers, improved its barrier property.
First nylon layer, it is strong to improve surface printing ability, high temperature resistant flatiron, stretch-proof ability;
The one PE layer, raising are endured property, are prevented to curl, have moisture barrier property;
Second nylon layer and the 3rd 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 2nd PE layer, moisture barrier property is good, is easy to heat-sealing;
First bonding coat, second bonding coat and the 3rd bonding coat 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 packaging film, the storage life that its good barrier property, content be not perishable, can prolong meat products.
Description of drawings
The section structure scheme drawing of the multi-layer co-extruded packaging film of a kind of high-barrier that Fig. 1 relates to for the utility model.
Among the figure:
First nylon layer 1, first bonding coat 2, a PE layer 3, second bonding coat 4, second nylon layer 5, evoh layer 6, the 3rd nylon layer 7, the 3rd bonding coat 8, the 2nd PE layer 9.
The specific embodiment
Referring to Fig. 1, the multi-layer co-extruded packaging film of a kind of high-barrier that the utility model relates to, described packaging film is nine layers of coextruded film, and it is followed successively by from top to bottom: first nylon (PA) layer, 1, first bonding coat 2, a PE layer 3, second bonding coat 4, second nylon (PA) layer 5, EVOH(ethylene/vinyl alcohol copolymer) layer the 6, the 3rd nylon (PA) layer the 7, the 3rd bonding coat 8 and the 2nd PE layer 9.
Claims (1)
1. multi-layer co-extruded packaging film of high-barrier, it is characterized in that: described packaging film is nine layers of coextruded film, and it is followed successively by from top to bottom: first nylon layer (1), first bonding coat (2), a PE layer (3), second bonding coat (4), second nylon layer (5), evoh layer (6), the 3rd nylon layer (7), the 3rd bonding coat (8) and the 2nd PE layer (9).
