Abstract

The invention aims at providing a method for producing direct transfer laser hologram lining paper, which can be used for obtaining fine and clear laser patterns and comprises the following steps of: performing laser hologram mold compression and vacuum aluminizing on a BOPP (Biaxially-Oriented Polypropylene) film, coating a coating layer on the aluminized layer, stripping out the BOPP film after the coating layer is compounded with original paper through rolling, and coating gloss oil. Through the method, the technical process is simplified, the pure aluminum foil layer in the common laser hologram lining paper is omitted, and the adhesive is compounded by using a dry method. Compared with the compounding of common laser aluminum foil, the use amount of metal aluminum and the adhesive is omitted, and the energy consumption and the production cost are reduced. By using water-based back paint and surface paint, the harm of auxiliaries remained in the raw paint to the environment and human bodies is eliminated, the stripped BOPP film can be reused, and another mold compression of laser hologram patterns is not required.

Description

The production method of lining paper in the laser hologram that cigarette pack uses is radium-shine

Technical field

The present invention relates to the preparation method of packaging material, especially the production method of the radium-shine interior lining paper of laser hologram of cigarette pack use.

Background technology

The medium and high-grade goods 90% of cigarette all use common laser hologram laser aluminium-foil paper at present, the whole surface of laser aluminium-foil paper has holographic false proof literal or pattern, many owing to relating to sciemtifec and technical sphere simultaneously, complex process, with high content of technology, increased counterfeit difficulty greatly, possess good antiforge function, thereby this production cost is higher.Under this background, reducing cost of manufacture as far as possible is the common target of pursuing of each manufacturing enterprise: the aluminum foil thickness of common laser hologram laser aluminium-foil paper is generally 6～7 microns, and the aluminum layer thickness that directly shifts the radium-shine interior lining paper of laser hologram only is 300～400 dusts, aluminum foil thickness is about about 200 times of transfer membrane aluminium thickness, from energy savings, adopt direct transfer method to make the consumption that the radium-shine interior lining paper of laser hologram has been saved metallic aluminium and adhesive, reduced energy consumption and production cost.

CN101037852A discloses a kind of manufacturing method of cigarette inside lining direct plating laser paper, main processes is included in body paper surface brushing surface coating layer, carry out laser molding through the body paper after the brushing, aluminize through the body paper behind the laser molding, through after aluminizing again brushing one deck coating obtain cigarette inside lining direct plating laser paper.This method has been simplified technical process, has removed the adhesive in the shifting process, film, has saved the consumption of aluminium.But, can not obtain meticulous and laser pattern clearly because the ply of paper surface ratio is more coarse.

CN101100833A discloses a kind of manufacture method of laser direct plating tipping paper, comprises making water paint, is coated with water paint on the BOPP of embossed holographic laser pattern film, fits with yew paper body paper, peels off the BOPP film, aluminizes, and makes laser direct plating tipping paper.Therefore below aluminium coated, the thin portion of some of laser pattern is covered with the holographic laser pattern covers for this method, can not obtain meticulous and laser pattern clearly.

Summary of the invention

The object of the present invention is to provide the production method that can obtain the radium-shine interior lining paper of direct transfer laser hologram meticulous and laser pattern clearly.

The production method of lining paper in the laser hologram that cigarette pack of the present invention uses is radium-shine may further comprise the steps:

A. radium-shine film production: the BOPP film is carried out the laser hologram laser molding, form the laser hologram laser pattern on the BOPP film, the mold pressing surface on the BOPP film is carried out vacuum aluminum-coated, coating one coating on aluminium coated; Normal temperature cure 6～48 hours;

B. compound: adhesive coating on coating after the curing or body paper, radium-shine film of BOPP and body paper roll-in is compound; Compound back goods normal temperature solidified 6～48 hours down;

C. peel off: the semi-finished product that are cured are separated the BOPP film;

D. cut: after cutting, promptly draw laser hologram radium-shine in lining paper.

Among the present invention, the BOPP film is a bidirectional stretching polypropylene film, is the film that is formed through stretch processes by acrylic resin, and thickness can be chosen between 0.05～0.5mm.

The used coating of coating is by the acrylic acid of weight percent hundred to 10～25%, acrylate or derivatives thereof, 2～5% methyl acetate or ethyl acetate, 1.5～2.5% sodium lauryl sulfate, the water of 1～1.5% ammonium persulfate, 20～30% ethanol and surplus is formed.Preferably by 7～10% butyl methacrylate, 7～10% methyl methacrylate, 0.7～1.3% acrylic acid, 2～5% methyl acetate or ethyl acetate, 1.5～2.5% sodium lauryl sulfate, the water of 1～1.5% ammonium persulfate, 20～30% ethanol and surplus is formed.

Adhesive is by acrylic acid, acrylate or derivatives thereof, 4-8% methyl acetate or the ethyl acetate of weight percent hundred to 25～40%, 3～5% sodium dodecyl benzenylsulfonate, and 2～3% the potassium peroxydisulfate and the water of surplus or ethanol are formed.Preferably by 12～16% methyl acrylate, 12～16% methyl methacrylate, 2～4% methacrylic acid, 4～8% methyl acetate or ethyl acetate, the sodium dodecyl benzenylsulfonate of 3-5%, 2～3% the potassium peroxydisulfate and the water of surplus are formed.

The semi-finished product that separate behind the BOPP film can also be coated with the water-soluble gloss oil of one deck on aluminium lamination.

The present invention has simplified technical process, has removed pure aluminum foil layer and dry composite adhesive in the lining paper in the common laser holographic laser, with compound the comparing of common radium-shine aluminium foil, has saved the consumption of metallic aluminium and adhesive, has reduced energy consumption and production cost; Adopt water-based back paint and coating materials, eliminated former coating residual additive to environment and the potential harm of human body, the BOPP film after peeling off can also be reused, and does not need mold pressing laser hologram laser pattern once more.

The specific embodiment

Produce lining paper in the soft box cigarette of a Shanghai Cigarette Factory " China " board, specification is 74g114mm, and production quantity is 200 meters.

On the BOPP of 0.2mm film, carry out the laser hologram laser molding, vacuum aluminum-coated on mold pressing surface, on roll coating apparatus, be coated with a coating to aluminium coated, the anilox roll 150 order 65um that roll coating apparatus uses, the coated coating formulation weight is such as following: 8% butyl methacrylate, 8% methyl methacrylate, 1% acrylic acid, 3% methyl acetate, 2% sodium lauryl sulfate, 1% ammonium persulfate, 52% water and 25% ethanol are formed.

Deposit at normal temperatures and solidify after 24 hours, obtain the radium-shine film of BOPP.

Coating binder on the coating of the radium-shine film of BOPP or body paper, radium-shine film of BOPP and body paper roll-in is compound, park under the normal temperature and solidify after 24 hours, separate the BOPP film again.Adhesive weight percent hundred is than composed as follows: 15% methyl acrylate, 16% methyl methacrylate, 3% methacrylic acid, 6% methyl acetate or ethyl acetate, 5% sodium dodecyl benzenylsulfonate, 3% potassium peroxydisulfate, 52% water.

After separating the BOPP film,,, guarantee cigarette machine adaptability to strengthen product surface ABRASION RESISTANCE and smooth degree at the water-soluble gloss oil of front coating one deck, after cutting, promptly draw laser hologram radium-shine in lining paper.

The finished product detection data:
