Embodiment Construction

[0023] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0024] Process of the present invention such as figure 1 As shown, the release layer is mainly coated on the PET film, and then the coloring layer is coated on the release layer. The effect of the laser layer is molded on the coloring layer. The laser layer is vacuum-plated with aluminum, and then the adhesive is coated. Finally cut into finished products.

[0025] Among them, the coating release layer: additives (silicon oil, water wax, OP wax, polytetrafluoroethylene, oxidized polyethylene, cellulose acetate, etc.) can be dissolved: firstly weigh the methyl ethyl ketone: toluene solution in a ratio of 1:1 , placed in a heating insulation bucket, heated and kept warm to ≥40°C; then weigh the additive and dissolve it in a toluene solution ≥40°C; finally pour the dissolved additive into the mixed solution in the insulation bucket. (Th...

Abstract

The invention mainly discloses a cold-hot film process which comprises the following steps of: firstly, cutting a needed PET (polyethylene terephthalate) film, and coating a releasing layer on the PET film; secondly, coating a coloring layer on the releasing layer, stamping a laser layer effect on the coloring layer, performing vacuum-plating of aluminum above the laser layer, and coating a back glue; and finally, cutting the prepared finished product. The process disclosed by the invention has the advantages of high thermo-printing speed, high accuracy, and short production cycle; and the final product can embody a gradual changing effect and has strong stereovision.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular to a cold stamping film process for label printing and commercial printing. Background technique [0002] In the fierce market competition, in order to increase the added value of products and carry out packaging anti-counterfeiting more effectively, more and more packaged goods need to adopt cold stamping technology. This study discusses the status quo and development of cold stamping technology, its types and manufacturing principles, and analyzes the advantages and disadvantages of cold stamping technology and hot stamping technology. Cold perm technology is generally divided into two types: dry cold perm and wet perm. Cold perm technology uses the method of printing adhesive to transfer metal foil, which is low in cost, energy saving and high in production efficiency. It is a new technology that meets the needs of the future processing market. [0003] In recent year...
