Abstract
The utility model relates to a multi-layer co-extrusion high-temperature cooking film. The utility model is characterized in that the cooking film is a seven-layer co-extrusion thin film, that is, the cooking film comprises a first nylon layer (1), a first bonding layer (2), a polyvinyl layer (3), a second bonding layer (4), a second nylon layer (5), a third bonding layer (6) and a medium density metallocene polyvinyl layer (7), which are sequentially arranged from the top down. The cooking film has the advantages of good stiffness, good barrier property, high-temperature cooking resistance, no peculiar smell, prolonged content product quality guaranteeing period, and guaranteed practicability safety.
Description
Technical field
The utility model relates to a kind of multi-layer co-extruded Tropical cooking film, belongs to the packaging material for food technical field.
Background technology
Retort pouch is the composite plastic film bag that can carry out heat treated, and how the used composite plastic film of existing retort pouch is composited with trilaminate material, and the membrane structure of representative retort pouch is: outer is polyester film, makes to strengthen usefulness; The middle level is an aluminium foil, does against sunshine, damp proof and anti-gas-leak usefulness; Internal layer is polyolefin film (as a polypropylene screen), makes heat seal and contact food and uses.Its defective is, behind the thermophilic digestion, and delamination easily, bubble between each layer, content product is perishable; In addition, during owing to MULTILAYER COMPOSITE, adopt glue more, contain toluene in the glue, influence food security, and easily produce peculiar smell.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of multi-layer co-extruded Tropical cooking film of digestion resistant is provided.
The purpose of this utility model is achieved in that a kind of multi-layer co-extruded Tropical cooking film, described boiling film is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: first nylon layer, first adhesive layer, polyethylene layer, second adhesive layer, second nylon layer, the 3rd adhesive layer and middle density metallocene PE layer.
The beneficial effect of the multi-layer co-extruded Tropical cooking film of the utility model is:
The utility model is made of the stack of seven tunics, by having complementary functions between the different plastic layers, improves its combination property;
First nylon layer and second nylon layer strengthen mechanical property, improve very property, and gases such as oxygen are had certain barrier, are barrier layer;
Polyethylene layer, raising is endured property, is prevented to curl, and can be used for high-speed packaging, and has moisture barrier property;
In density metallocene PE layer, heat sealable, anti-boiling, can anti-121 ℃ of high-temperature sterilizations;
First adhesive layer, second adhesive layer and the 3rd 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 multi-layer co-extruded Tropical cooking film of the utility model, very good, the good barrier property of property, digestion resistant and free from extraneous odour prolong the content product shelf-life, guarantee practical safety.

Among the figure:
The specific embodiment
Referring to Fig. 1, a kind of multi-layer co-extruded Tropical cooking film that the utility model relates to, described boiling film is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: first nylon (PA) layer, 1, first adhesive layer 2, polyethylene (PE) layer 3, second adhesive layer 4, second nylon (PA) layer the 5, the 3rd adhesive layer 6 and middle density metallocene PE (MDPE) layer 7.
First adhesive layer 2, second adhesive layer 4 and the 3rd adhesive layer 6 all adopt the TIE of Dupont.
