Abstract
The utility model relates to a multilayer co-extrusion packaging bag and belongs to the technical field of a food packaging material. The multilayer co-extrusion packaging bag is characterized in that the packaging bag is formed in a mode that seven layers of co-extrusion thin films are subjected to heat seal; and the seven layers of co-extrusion thin films respectively are a first nylon layer (1), a first bonding layer (2), a first PE (polyurethane) layer (3), a second bonding layer (4), a second nylon layer (5), a third bonding layer (6) and a second PE layer (7) from the surface layer to the inner layer sequentially. The multilayer co-extrusion packaging bag disclosed by the utility model has good barrier property; contents in the multilayer co-extrusion packaging bag are difficult to go bad; and the storage period of food can be prolonged.
Description
Technical field
The utility model relates to a kind of multi-layer co-extruded packaging bag.Belong to the packaging material for food technical field.
Background technology
At present, the packing film of food need have blocking water, hinder high obstructing performance such as oxygen, to prolong the storage life of food.Conventional single thin film, its performance ratio is more single, barrier is poor, can not satisfy operating needs, as crossing the requirement of the container for long-term storage will reach food, 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, and a kind of multi-layer co-extruded packaging bag is provided, the storage life that its good barrier property, content be not perishable, can prolong food.
The purpose of this utility model is achieved in that a kind of multi-layer co-extruded packaging bag, described packaging bag is formed by the heat seal of seven-layer co-extrusion film, and described seven-layer co-extrusion film is followed successively by by top layer to nexine: first nylon layer, first bonding coat, a PE layer, second bonding coat, second nylon layer, the 3rd bonding coat and the 2nd PE layer.
The beneficial effect of the multi-layer co-extruded packaging bag of the utility model is:
The utility model adopts seven-layer co-extrusion film thermal synthesis bag, by having complementary functions between the different plastic layer of coextruded film, improves its barrier property.
First nylon layer, it is strong to improve surface printing ability, high temperature resistant flatiron, stretch-proof ability, improves barrier property simultaneously;
The one PE layer, raising are endured property, are prevented to curl, have moisture barrier property;
Second nylon layer strengthens mechanical property, improves the stretch-proof ability, and gases such as oxygen are had certain barrier, is 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 bag, the storage life that its good barrier property, content be not perishable, can prolong food.
Description of drawings
The single face section structure scheme drawing of a kind of multi-layer co-extruded packaging bag that Fig. 1 relates to for the utility model.
Among the figure:
The specific embodiment
Referring to Fig. 1, a kind of multi-layer co-extruded packaging bag that the utility model relates to, described packaging bag is formed by the heat seal of seven-layer co-extrusion film, and described seven-layer co-extrusion film is followed successively by by top layer to nexine: first nylon (PA) layer, 1, first bonding coat 2, a PE layer 3, second bonding coat 4, second nylon (PA) layer the 5, the 3rd bonding coat 6 and the 2nd PE layer 7.
Described first bonding coat 2, second bonding coat 4 and the 3rd bonding coat 6 all adopt the TIE of Dupont.
