The utility model relates to a kind of packaging material, particularly relates to a kind of package compound film of media-resistant, belongs to packing technique field.
Background technology
Package compound film obtains applying more and more widely with its material lightweight, easy to use, cost performance advantages of higher, but requires that higher special dimension is still based on hard packing, as metal can, vial, modified plastics bottle etc. at media-resistant.Main cause is, these special application fields, such as missible oil class agricultural chemicals, and the Elements in Organic Solvents contained by its content is more complicated, corrosivity is comparatively strong, requires higher to the media-resistant of packaging material.
Media-resistant flexible packing material conventional at present, primary structure has: polyester/aluminum foil/cast polypropylene (PET/Al/CPP write a Chinese character in simplified form in letter), polyester/aluminum foil/polyamide/cast polypropylene (PET/Al/PA/CPP write a Chinese character in simplified form in letter), and the many coextrusion polypropylene composite film containing polyamide (PA write a Chinese character in simplified form in letter) or ethylene/vinyl alcohol copolymer (EVOH write a Chinese character in simplified form in letter).But they respectively have pluses and minuses in performance, if PET/Al/CPP is in packaging heat-sealing, accumulating or use link, the easy impaired cracking of aluminium foil, thus affect the barrier property of its reality; PET/Al/PA/CPP is many due to number of layers, and need point three compounds, packing cost is higher; Many coextrusion polypropylene composite film containing PA or EVOH, its barrier property is limited, not at a class compared with the composite membrane containing aluminium foil, and PA and the EVOH all easily moisture absorption.In addition, above-mentioned composite membrane adopts dry skill of returning to work to make usually, and the polyurethane adhesive of its internal layer is often subject to the impact (as swelling) of pack content organic solvent, causes packaging bag to corrode layering and even leaks, there is potential safety hazard.
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.
