The high light silver of water-based transfer membrane structure
Technical field
The utility model relates to a kind of structure of transfer membrane, relates in particular to the structure of the high light silver of a kind of water-based transfer membrane, is mainly used in packing boxes such as preparation cigarette, drinks, cosmetics, food, medicine and uses paper.
Background technology
Along with the raising of living standards of the people, also increasingly high to the requirement of the packing of product.The packing of product is no longer leted others have a look at the coarse old appearance of making so that pattern is simple, remoulds oneself thoroughly one after another, requires to have the texture of bright in color, metal, to improve and to beautify the visual effect of packing.In order to reach this kind effect, the mode that people often are employed in paper surface paper aluminium foil makes this beautiful wrapping paper, but this kind wrapping paper thickness is thicker; Aluminium foil surface contacts easy oxidized for a long time and makes its quality gloomy with air; Influence packing effect, and it is difficult to degraded, not environmental protection.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, a kind of degradable is provided, has bright in color, the high light silver of the water-based of the texture of metal transfer membrane structure.
The purpose of the utility model is achieved in that the high light silver of a kind of water-based transfer membrane structure, and it comprises the PET basement membrane, and said PET membrane surface is coated with the water paint layer, and said water paint laminar surface is provided with aluminium coated; Said PET basement membrane is three-layer co-extruded PET film, and its thickness is 15-20 μ m, and said aluminium coated is a vacuum aluminium coated layer; Said aluminum layer thickness is the 600-700 dust.
Said water paint adopts benzene emulsion/aqueous polyurethane coating.
The beneficial effect of the high light silver of the utility model water-based transfer membrane structure is:
The high light silver of the utility model water-based transfer membrane structure adopts three-layer co-extruded PET film as basement membrane, and its deflection is good, dimensionally stable; Be 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.
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.
Aluminum layer thickness is thick, reaches the 600-700 dust, and brightness is high, the metal sense strong, make the beautiful elegance of packing box, for beautifying of commodity played the effect of making something perfect even more perfect, and its degradable, environmental protection.

Among the figure:
PET basement membrane 1;
Water paint layer 2;
Aluminium coated 3.
The specific embodiment
Referring to Fig. 1, the high light silver of a kind of water-based that the utility model relates to transfer membrane structure, it comprises PET basement membrane 1, and said PET basement membrane 1 surfaces coated is covered with water paint layer 2, and said water paint layer 2 surface are provided with aluminium coated 3; Said PET basement membrane 1 is three-layer co-extruded PET film, and its thickness is 15-20 μ m, and said water paint adopts benzene emulsion/aqueous polyurethane coating, and said aluminium coated 3 is a vacuum aluminium coated layer.
Said aluminium coated 3 thickness are the 600-700 dust.
During use, gluing on aluminium coated, compound with paper again, then the PET basement membrane to be peeled off, aluminium coated is just transferred on the paperboard surface through adhesive action, and the packing that just forms the texture with bright in color, metal is used paperboard.Water paint layer had wherein both played easy effect of peeling off with the PET basement membrane, formed layer protective layer on the aluminium coated surface again simultaneously, prevented the aluminium coated surface oxidation, made it remain the gloss of Gao Liang.
