Utility model content
It is high that the technical problems to be solved in the utility model is to provide a kind of barrier, the permeating corrosion of the organic solvent of resistance to content, moderate cost, the package compound film of use safety.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of package compound film of media-resistant, it is characterized in that: be composited by printed layers, the first adhesive layer, high barrier aluminum-plating thin layer, the second adhesive layer, hot sealing layer successively from outside to inside.
Preferably, described printed layers is biaxial tension pet film, and thickness is 8 ~ 12um.
Preferably, described first adhesive layer is cohesive macromolecule resin, thickness 8 ~ 20um.
Preferably, described high barrier aluminum-plating thin layer is biaxial tension PETG metallized film, and aluminum layer thickness is 400 ~ 1000 Ethylmercurichlorendimides, and gross thickness is 8 ~ 12um.
Preferably, described second adhesive layer is modified high-molecular binding resin, and thickness is 8 ~ 20um.
Preferably, described hot sealing layer is improved polyalkene film, and thickness is 20 ~ 100um.
The package compound film that the utility model provides, high barrier aluminum-plating film is adopted to substitute traditional aluminium foil, overcome the shortcoming of the easily damaged cracking of aluminium foil, the barrier property of its barrier property and aluminium foil relatively, is significantly better than the many coextrusion polypropylene composite film containing PA or EVOH simultaneously; Second adhesive layer directly selects modified high-molecular binding resin, and do not use the adhesive for polyurethane being vulnerable to the impact of organic solvent swelling, medium-resistance is good, fundamentally avoids the risk of corrosion layering; In production technology, adopt extrusion composite technology, two curtain coating compounding machine of extruding once can complete compound, and production efficiency is high, and the process-cycle is short, moderate cost.
Accompanying drawing explanation
The package compound film schematic diagram of the media-resistant that Fig. 1 provides for the utility model.
Detailed description of the invention
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The package compound film schematic diagram of the media-resistant that Fig. 1 provides for the utility model, the package compound film of described media-resistant comprises from outside to inside successively: printed layers 1, the first adhesive layer 2, high barrier aluminum-plating thin layer 3, second adhesive layer 4, hot sealing layer 5.
Printed layers 1 is biaxial tension pet film (PET write a Chinese character in simplified form in letter), and thickness is 8 ~ 12um.Preferred substrates thickness 12umPET, this material has the processing characteristicies such as excellent printing adaptability and stretch-proof, can be obtained the printed layers of required picture and text by the mode of inner print.
First adhesive layer 2 is cohesive macromolecule resin, thickness 8 ~ 20um.Preferred employing is two extrudes curtain coating compounding machine, and obtain the first adhesive layer by the casting head of the first extruder, thickness is 12um.
High barrier aluminum-plating thin layer 3 is biaxial tension PETG metallized film (VMPET write a Chinese character in simplified form in letter), and aluminum layer thickness is 400 ~ 1000 Ethylmercurichlorendimides, and gross thickness is 8 ~ 12um.Preferred employing 12umVMPET, thickness of aluminizing is 600 Ethylmercurichlorendimides, and employing is two extrudes curtain coating compounding machine, and its face of aluminizing is bonded together with printed layers 1 by the first tack coat 2.
Second adhesive layer 4 is modified high-molecular binding resin, and thickness is 8 ~ 20um.Firm particle (Bynel write a Chinese character in simplified form in letter) is visitd by preferred Du Pont, and employing is two extrudes curtain coating compounding machine, obtains the second adhesive layer, thickness 12um by the casting head of the second extruder.
