Abstract
The invention discloses a method for manufacturing a high-barrier composite membrane. The method for manufacturing the high-barrier composite membrane comprises the following steps: compounding a printing layer with a high-barrier layer by using a first adhesive layer to obtain a composite membrane, and then compounding the composite membrane with a heat sealing layer by using a second adhesive layer, wherein the high-barrier layer is a vinylidene chloride-acrylate copolymer biaxially-oriented membrane; the printing layer is a biaxially-oriented polyethylene terephthalate film or a biaxially-oriented polyamide membrane; the heat sealing layer is a polyethylene membrane or a polypropylene membrane. A product obtained by the method is excellent in water vapor barrier property and oxygen barrier property, and capable of effectively protecting contents and blocking transmission of water vapor and oxygen; the product obtained by the method is stable in barrier property, so that the barrier property of the composite membrane is not changed basically, and the stable barrier property is retained; the product obtained by the method has resistance to mechanical fatigue, so that an organic layer is capable of effectively tolerating influence of drawing, rubbing, twisting and impacting in processes of compounding, processing, packaging, storing, transporting and using the membrane; the high barrier property is retained.
Description
Technical field
The present invention relates to package compound film manufacturing method, be specifically related to a kind of high-barrier composite membrane manufacture method.
Background technology
The barrier of packaging material is most important for the protection of content.The one, the barrier of steam, for the food that is rich in moisture, if the water vapo(u)r transmission of packaging material is too high, means that moisture dissipation speed is too fast, and food is easy to produce dehydration, loses mouthfeel; The 2nd, the barrier of oxygen, particularly, for the higher food of some fat contents, under oxygen effect, grease is easily oxidized, and product quality degradation even endangers food security.
The plastic flexible package of high barrier has obtained application comparatively widely at present.Common material has: aluminium foil, metallized film, silica vapor-deposited film, ethene-polyvinyl alcohol copolymer film etc.Also there is advantage and shortcoming separately in above-mentioned material.Aluminium foil and metallized film have very high barrier, can be opaque, and can not be for microwave food packaging.Silica vapor-deposited film price is too expensive, and has mechanical fatigue problem, and in compound, packing, storage and transport process, barrier can decline because of the damage of inorganic barrier layer.Ethene-polyvinyl alcohol copolymer film can significantly decline along with humidity increases its barrier, and its barrier for steam is poor.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of high-barrier composite membrane manufacture method is provided.
High-barrier composite membrane manufacture method, comprises and printed layers and high-obstruction is carried out compound with the first adhesive layer, resulting composite membrane carries out compound with hot sealing layer with the second adhesive layer again.
Described high-obstruction is vinylidene chloride-acrylate copolymer biaxial stretching film.
Described printed layers is biaxial tension PETG film or two-way stretching polyamide film.
Described hot sealing layer is polyethylene film or polypropylene screen.
Beneficial effect after the invention process:
1. high steam barrier and oxygen-barrier property, effectively protects content, blocks seeing through of steam and oxygen;
2. barrier is steady, and under higher humidity and temperature condition, the barrier of composite membrane does not change substantially, sees the barrier that can remain stable;
3. resistance to mechanical fatigue, in Film laminated processing, packing, accumulating, use procedure, the impact that its organic layer can effectively tolerate stretching, friction, kink, impact, keeps higher barrier.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-barrier composite membrane of obtaining of the present invention;
In figure, printed layers 1, high-obstruction 2, hot sealing layer 3, adhesive layer 4.1, adhesive layer 4.2.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
embodiment 1
First printed layers 1 and high-obstruction 2 use the first adhesive layers 4.1 are carried out compoundly, resulting composite membrane carries out compound with hot sealing layer 3 use the second adhesive layers 4.2 again.High-obstruction 2 is vinylidene chloride-acrylate copolymer biaxial stretching films; Printed layers 1 is biaxial tension PETG film; Hot sealing layer 3 is polyethylene film.
First printed layers 1 and high-obstruction 2 use the first adhesive layers 4.1 are carried out compoundly, resulting composite membrane carries out compound with hot sealing layer 3 use the second adhesive layers 4.2 again.High-obstruction 2 is vinylidene chloride-acrylate copolymer biaxial stretching films; Printed layers 1 is two-way stretching polyamide film; Hot sealing layer 3 is salivation polypropylene screen.
Claims (4)
