Production method for partial laser holography transfer paper

Abstract

The invention belongs to the field of laser holography anti-fake packaging materials and in particular relates to a production method for partial laser holography transfer paper. The production methodcomprises the following steps: (1) performing coating, namely according to layout designing requirements of partial transfer paper, manufacturing a special edition coating anilox roller, and partially coating a PET (polyethylene terephthalate) base membrane by a transfer coating; (2) performing mold pressing, namely performing mold pressing on laser holography anti-fake information on a mold pressing machine, wherein holography information is mold-pressed in an area coated by the transfer coating, and an area without the transfer coating is not provided with the holography information; (3) performing aluminum plating, namely performing aluminum plating according to a normal laser holography aluminum plating process, enabling an aluminum layer to adhere to the coating in the area coated bythe transfer coating, and enabling an aluminum layer to adhere to the PET base membrane in the area without the transfer coating; and (4) performing combining peeling, namely smearing a transfer adhesive in a whole edition on a combining machine to combine an aluminum layer surface of the laser holography partial transfer membrane with paper, and peeling off the PET base membrane, so as to obtainpartial transfer paper. The edge of the partial transfer paper obtained by using the method is tidy, and the packaging molding speed can be greatly increased, that is, is up to 800 pieces of paper / minute at most.

Description

technical field [0001] The technology belongs to the field of laser holographic anti-counterfeiting packaging materials, and particularly relates to a production method of partial laser holographic transfer paper. Background technique [0002] Laser holographic transfer paper has been widely used in the fields of tobacco and wine, medicine and cosmetic packaging due to its high anti-counterfeiting strength and gorgeous packaging effect. The production of laser holographic transfer paper is usually to prepare the laser holographic anti-counterfeiting transfer film first, and then use the transfer adhesive to transfer the laser holographic anti-counterfeiting information from the transfer film to the paper through a composite process. The production process of the laser holographic transfer film is to first coat the thermoplastic polymer coating on the PET base film, and then emboss the laser holographic anti-counterfeiting information on the transfer coating through a molding...

AI Technical Summary

Problems solved by technology

Although this process can produce partial transfer paper, due to the strong fluidity of the glue, it is not easy to make the edges of the partial hollowed out part neat when compounding the glue

The uneven edges will not only seriously affect the packaging effect, but also the overflowing glue will stick to the printing blanket during printing, resulting in more waste products
