Abstract
The invention relates to a high-barrier retort pouch. The high-barrier retort pouch comprises a pouch body, wherein an opening sealing strip is arranged at an opening of the pouch body; the pouch body consists of a silicon coating layer, a polyester film layer, a first adhesive layer, a polyamide film layer, a second adhesive layer and a polyethylene film layer; the polyester film layer is integrally bonded with the polyamide film layer through the first adhesive layer; the polyethylene film layer is bonded on the polyamide film layer through the second adhesive layer; the silicon coating layer is arranged on the polyester film layer. The high-barrier retort pouch has a good barrier property, and the polyester is resistant to high temperature, so that bag breakage and layering phenomena after high-temperature steaming are avoided.
Description
Technical field
The present invention relates to a kind of packaging bag, especially a kind of high-barrier retort pouch.
Background technology
In packaging industry, the barrier property of aluminium foil is fine, generally wants the composite that barrier property is good all can use aluminium foil, and that broken bag phenomenon occurs aluminum foil compound bag after thermophilic digestion is frequent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of have have good barrier property, high temperature resistant, the high-barrier retort pouch that can solve the broken bag lamination after thermophilic digestion.
According to technical scheme provided by the invention, described high-barrier retort pouch, comprise bag, opening part at bag is provided with sealing strip, described bag consists of silicon coating, laminated polyester film, the first adhesive phase, polyamide film layer, the second adhesive phase and film layer, laminated polyester film and polyamide film layer, by the first adhesive phase bonding one, are bonded with film layer by the second adhesive phase on polyamide film layer, are provided with silicon coating on laminated polyester film.
The thickness of described laminated polyester film is 10 ~ 15 um.
The thickness of described polyamide film layer is 10 ~ 20um.
The thickness of described film layer is 60 ~ 90um.
The present invention has good barrier property, and polyester is high temperature resistant again, thereby has solved the broken bag lamination after thermophilic digestion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of bag in the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This high-barrier retort pouch, comprise bag 1, opening part at bag 1 is provided with sealing strip 2, described bag 1 consists of with film layer 8 silicon coating 3, laminated polyester film 4, the first adhesive phase 5, polyamide film layer 6, the second adhesive phase 7, laminated polyester film 4 passes through the first adhesive phase 5 bonding one with polyamide film layer 6, on polyamide film layer 6, by the second adhesive phase 7, be bonded with film layer 8, on laminated polyester film 4, be provided with silicon coating 3.
The thickness of described laminated polyester film 4 is 10 ~ 15 um.
The thickness of described polyamide film layer 6 is 10 ~ 20um.
The thickness of described film layer 8 is 60 ~ 90um.
The present invention adopts the laminated polyester film 4 of silicon coating 3 greatly to increase barrier property, and the first adhesive phase 5 and the second adhesive phase 7 adopt thermophilic digestion glue 2781, and the dimensions of bag 1 is: 220mm * 350mm.
