Embodiment Construction

[0019] Such as figure 1 , figure 2 Shown, a kind of cold perm film, comprises PET film 1, is coated with release layer 2 on PET film 1, is coated with colored layer 3 on release layer 2, molded laser layer on the colored layer 3, the laser layer There is a vacuum aluminized layer 4 on the top, and the back glue 5 is coated on the vacuum aluminized layer 4. The coloring step in the coloring layer 3 is: first add the coloring solvent, then add the toner, stir for 10 minutes, and then add the coloring layer paint , when the ambient temperature is ≥ 25°C, stir for 1 hour, and when the ambient temperature is <25°C, stir for 1.5 hours; the proportion of resin and solvent must be accurate to 10g, the proportion of toner must be accurate to 1g, and the solid content of the paint should be controlled at 21 ±0.5%, the viscosity is controlled at 18±1 second; the coloring solvent is one of butanone, ethyl ester, propyl ester, butyl ester and ethanol.

[0020] As an improvement of the p...

Abstract

The invention relates to a cold ironing film. The film comprises a PET thin film, the PET thin film is coated with a release layer, the release layer is coated with a coloring layer, a laser layer is arranged on the coloring layer in a mould pressing manner, a vacuum aluminizing layer is arranged on the laser layer, and is coated with gum, and the material of the gum comprises, by weight, 80 parts of natural rubber, 20 parts of butadiene rubber br9000, an auxiliary material and an addition agent; the auxiliary material comprises, by weight, 5 parts of indirect zinc oxide, 1 part of stearic acid, 0.2 part of coumarone resin and 7 parts of solar oil Sunpar2280; the strength of the gum on the surface layer of the cold ironing film is high, and impact resistance is achieved.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular to a cold stamping film used for label printing. Background technique [0002] Cold stamping film is relative to hot stamping film. In the production process, uv adhesive is used to transfer the hot stamping film to the printing material. In theory, all hot stamping on smooth plastic body surfaces and non-attractive paper surfaces using uv adhesives are suitable for cold stamping. In order to increase the added value of products and more effectively package anti-counterfeiting, more and more packaged goods need to use Cold stamping technology, the early hot stamping foil technology is mainly hot stamping foil, in recent years the rapid development of cold stamping technology, and can be applied to flexographic printing, lithographic printing, etc., cold stamping technology is different from hot stamping technology requires complex equipment, and the production speed is fa...
