Abstract

The invention provides a method for manufacturing a holographic aluminized paper material in order to solve the problem that a holographic aluminized paper material of the same type, which has the traditional water based coating coated on a thin film, has poor appearance effect, great production difficulty or difficult repeated use of the stripped thin film and causes high manufacturing cost and big waste of holographic directly plated lining paper. The invention adopts a technical scheme that: the process comprises the following steps: performing holographic mould pressing on a thin film, coating a layer of the water based coating on the thin film, compounding the thin film and a paper material paper base by pressing, baking the thin film and the paper material paper base, stripping off the thin film to obtain the paper material paper base with a holographic texture, and plating an aluminous layer on the paper material paper base with holographic texture with a vacuum aluminizing machine to form the holographic aluminized paper material; and the method is characterized in that: the thin film adopts a single-face heat seal type biaxially oriented polypropylene thin film and a surface tension of the heat seal face of the thin film is controlled to between 28 and 34dyn/cm through corona treatment before performing the holographic mould pressing.

Description

A kind of preparation method of holographic aluminized paper material
Technical field
The present invention relates to pack or the preparation method of printing material, specifically is a kind of preparation method of holographic aluminized paper material.
Background technology
Holographic aluminized paper material, be a kind of be base material with the paper, have printing packaging paper metallic luster, that have hologram pattern, as have gold card paper, silver foil of hologram pattern etc., be developed recently a kind of top grade, the novelty of getting up and anti-fraud functional packing or package printing material are arranged, can replace the technology of the gold stamping and transfer printing hologram pattern of on package or package printed matter large tracts of land.Along with the development of manufacturing technology, holographic aluminized paper material enjoys the consumer to welcome with its mirror metal gloss and false proof, environmental-protecting performance, is widely used as the packing or the package printing material every field of cigarette, wine, cosmetics, medicine and food etc.The demand in market is impelled the further R and D of people to the holographic aluminized paper material new technology.
Chinese patent discloses a kind of laser direct plating tipping paper No. 200720040607.8, it makes main points: be coated with the water paint layer earlier on yew paper, and then the bidirectional stretching polypropylene film of crossing the holographic laser pattern with mold pressing is fitted on the water paint layer, through entering oven for drying after the extruding, dry to yew paper moisture 5~8%, peel off bidirectional stretching polypropylene film, put into vacuum aluminum-coated machine again and plate aluminium lamination, just become laser direct plating tipping paper.The shortcoming of this technology is: yew paper is the paper that is easy to degenerate after a kind of very thin, suction, and water paint directly is coated in the load that can have a strong impact on yew paper above it, and outward appearance also has very big losing shape after the moulding, and its production difficulty is bigger.
Chinese patent application discloses a kind of preparation method of holography sputtering internal lining paper for No. 200810015903.1, the its preparation method main points are followed successively by: adopt the surface to scribble the film of separation layer, on film, carry out contour forging, in the water base compound adhesive of the last figure one deck of film, with film and interior lining paper paper substrate compacting compound back oven dry, obtain having the interior lining paper paper substrate of holographic line behind the stripping film, plate aluminium lamination having on the interior lining paper paper substrate of holographic line, just become holography sputtering internal lining paper by vacuum aluminum-coated machine.The shortcoming of this technology is: after being coated with separation layer on the film, separation layer can produce and come off or local shedding at compound, the oven dry of compacting, stripping process, so the film after peeling off is difficult to handle, and generally can not use repeatedly, cause the cost of manufacture height of holography sputtering internal lining paper, waste big.
Summary of the invention
Not good in order to overcome the existing existing appearance effect of similar holographic aluminized paper material that water paint is coated on the film, the production difficulty is big, film after perhaps peeling off is difficult to use repeatedly, cause the cost of manufacture height of holography sputtering internal lining paper, the defective that waste is big, the preparation method that the purpose of this invention is to provide a kind of improved holographic aluminized paper material can overcome the defective of prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of preparation method of holographic aluminized paper material, processing step includes: adopt a film, on film, carry out contour forging, on film, be coated with one deck water paint, with film and paper wood paper substrate compacting compound back oven dry, obtain having the paper wood paper substrate of holographic line behind the stripping film, plate aluminium lamination by vacuum aluminum-coated machine having on the paper wood paper substrate of holographic line, become holographic aluminized paper material, it is characterized in that: described film adopts the bidirectional stretching polypropylene film of single face heat-sealing type, before carrying out contour forging, the surface tension of film heat cover is controlled at 28~34dyn/cm (dynes per centimeter) by corona treatment.
The film of technique scheme preferably is controlled at 30~32dyn/cm through the surface tension of corona treatment.
Beneficial effect of the present invention: owing to select the bidirectional stretching polypropylene film of single face heat-sealing type for use, and before carrying out contour forging, by corona treatment the heat cover surface tension of film is controlled at 28~34dyn/cm, so before carrying out contour forging, need not apply separation layer, film just can directly have embossed holographic performance and enough stripping performances, does not influence the coating levelling of water paint subsequently again; Because water paint is to be coated on to be transferred to the paper wood paper substrate on the film again, so water paint time of staying on the paper wood paper substrate is few, particularly suitable is handled the paper that is easy to degenerate after the very thin suction, after being handled, such paper can keep original configuration of surface, the holographic information smooth that water paint carried, improve the radium-shine brightness after aluminizing greatly, and reduced the production difficulty.
The invention will be further described below in conjunction with embodiment.
