Description

Double-layer composite paper

Technical Field

The utility model relates to an inside lining packing field, in particular to double-deck composite paper can be used to packing such as food, medicine, cigarette.

Background

Traditional packing is for keeping moist dampproofing, uses the aluminium foil inside lining usually, adopts compound aluminium foil inside lining to pack, and the printing face is golden or silver, and non-printing face is the ground colour white, and the color effect is general. The laser film transfers the aluminum plating layer with laser information to the base paper, so that the base paper presents certain color, the product attractiveness is improved, and the laser film has an anti-counterfeiting function. Therefore, the search for a novel anti-counterfeiting, novel, attractive and environment-friendly packaging product becomes the demand of market development.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art, providing a double-layer composite paper, solving the problems of common color effect and less resource recycling.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a double-deck compound paper, is including shifting layer, anti-fake information layer, aluminizing layer, backing paper layer, aluminium foil layer and chromatograph, backing paper layer skin sets up the glue layer to its skin pass through the glue layer with aluminize layer bonds aluminizing layer surface sets up anti-fake information layer, anti-fake information layer surface sets up the layer that shifts, the backing paper layer nexine sets up the adhesive layer to its nexine passes through the bonding of gluing agent layer aluminium foil layer, simultaneously aluminium foil layer basal surface sets up the chromatograph.

The utility model discloses further inject the scheme:

preferably, the transfer layer is an aqueous polyurethane transfer coating layer.

Preferably, the glue layer is a styrene, butadiene, acrylic polymer glue layer.

Preferably, the adhesive layer is a polyvinyl alcohol adhesive layer.

Preferably, a plain surface laser film is arranged on the upper surface of the transfer layer.

Preferably, the plain surface laser film is a PET polyester film.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, can manage that solution color effect is general, problem that resource cyclic utilization is few, the utility model discloses outer transfer is aluminized, nexine composite aluminum foil, existing metallic luster, again pleasing to the eye anti-fake uses the plain face laser film of PET simultaneously, can cyclic utilization many times to all coating gloss oil are waterborne, and V0Cs discharges lowly, environmental protection more.

Detailed Description

Example 1

The embodiment provides a double-deck composite paper, as shown in 1, including transfer layer 1, anti-fake information layer 2, aluminize layer 3, ground paper layer 5, aluminium foil layer 7 and chromatograph 8, ground paper layer skin sets up glue layer 4, and its skin bonds through glue layer and aluminize layer 3, glue layer 4 is styrene, butadiene, acrylic acid polymer glue layer, set up anti-fake information layer 2 on the surface of aluminize layer, anti-fake information layer 2 sets up transfer layer 1 on the surface, the transfer layer is waterborne polyurethane transfer coating layer, be provided with plain surface laser film 9 on transfer layer upper surface, plain surface laser film is the PET polyester film, ground paper layer 5 nexine sets up adhesive layer 6, and its nexine passes through adhesive layer aluminium foil layer bonding, adhesive layer 6 is polyvinyl alcohol adhesive layer and 7 basal surfaces of aluminium foil layer set up chromatograph 8 simultaneously.

In the implementation of the embodiment, firstly, a layer of waterborne polyurethane transfer coating is coated on a PET film, then, a layer of anti-counterfeiting information layer is molded on the surface of the transfer layer, aluminum is plated on the surface of the anti-counterfeiting information layer, and then, the anti-counterfeiting information layer is compounded with the outer layer of the base paper through glue. Aging in an aging chamber to promote the volatilization of the solvent in the glue layer and the crosslinking and curing of the effective components, and then peeling off the PET film. And (3) coloring the inner layer of the base paper by using a polyvinyl alcohol adhesive wet-type composite aluminum foil, cutting the semi-finished product according to production requirements after finishing, extracting the product for quality detection, and packaging the product after the detection is qualified.

The utility model discloses outer transfer aluminizes, and the compound aluminium foil of nexine, existing metallic luster, again pleasing to the eye anti-fake uses the plain face laser film of PET, can manifold cycles utilize to all coating gloss oil are waterborne, and V0Cs discharges lowly, environmental protection more.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
