The seamless vegetarian noodles laser transfer membrane of water-based
Technical field
The utility model relates to a kind of structure of transfer membrane, and this kind transfer membrane is mainly used in packing boxes such as preparation cigarette, drinks, cosmetics, food, medicine and uses paper.
Background technology
The characteristics of transfer membrane are that hot strength is high, and Heat stability is good, percent thermal shrinkage are low, and surfacing is bright and clean, fissility good, can repeatedly use repeatedly.It mainly is used as vacuum aluminum-coated carrier, place vacuum aluminum-coated machine to aluminize the PET film exactly after, gluing and paper are compound, then the PET film are peeled off, the aluminium molecular layer is just transferred on the paperboard surface through adhesive action, forms the so-called paperboard of aluminizing.People are in order to pursue the beautiful effect of packing outer surface; Often increase its reflecting effect through improving surface smoothness; Make the packing box surface more and more brighter, but this kind change also only limit to the adjustment of color and brightness, does not have the gradual change chromatic effect; Form is more stiff, can not satisfy the packaging industry individual demand.And there is seam in this kind film between version and the version in coating procedure, follow-up making needs in the follow-up use to locate, and wastes bigger.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and need not to locate, smooth surface, has the seamless vegetarian noodles laser transfer membrane of water-based of color changeable effect, can satisfy the packaging industry individual demand, and this kind basement membrane is recyclable, and the feature of environmental protection is good.
The purpose of the utility model is achieved in that the seamless vegetarian noodles laser transfer membrane of a kind of water-based, and it comprises from bottom to top PET basement membrane, water paint layer and aluminium coated, and said water paint layer is seamless full coat layer, and its upper surface is provided with the radium-shine layer of vegetarian noodles.
Said PET basement membrane is three-layer co-extruded PET film, and its thickness is 15-20 μ m;
Said water paint adopts benzene emulsion/aqueous polyurethane coating, and said aluminium coated is a vacuum aluminium coated layer.
Said aluminum layer thickness is the 400-500 dust.
The beneficial effect of the seamless vegetarian noodles laser transfer membrane of the utility model water-based is:
The seamless vegetarian noodles laser transfer membrane of the utility model water-based, the water paint layer adopts seamless full coat layer, does not have seam between version and the version in the coating procedure, need not locate in the follow-up use, the convenient use, and practice thrift cost.The water paint layer feature of environmental protection is good, can not pollute environment, adopts benzene emulsion/aqueous polyurethane coating, can improve the surface tension of PET film, improves the adaptability (can use water-based ink) of printing, and can strengthen the adhesion of aluminium coated and PET basement membrane.The radium-shine layer on surface under the effect of light, can produce the gradual change chromatic effect with after aluminium coated combines, and can satisfy the packaging industry individual demand.
Adopt three-layer co-extruded PET film as basement membrane, its deflection is good, and dimensionally stable is suitable for secondary operations such as printing, paper bag, and it also has good heat-resisting, cold resistance and good chemical proofing and oil resistivity, cracky not, recyclable utilization.
