Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold foil technology, specifically to a novel offset cold foil composite film. Background Technology
[0002] Cold foil stamping is a printing concept relative to hot foil stamping. Cold foil stamping is a packaging product manufactured using a UV adhesive to transfer stamping foil onto a substrate. The entire transfer process does not use hot stencils or hot rollers, resulting in a large stamping area, high speed, and high efficiency.
[0003] However, existing cold foil structures still have shortcomings: the structural design is unreasonable, making it unable to adhere to the surface of ferrous or magnetic products. Moreover, the imaging layer of existing cold foils is in direct contact with the external environment, and during use, it is subject to friction damage from bumps and impacts, which affects the imaging quality of the imaging layer. Furthermore, the imaging layer is easily corroded by moisture and acidic substances in the environment, resulting in aging and fading, leading to a short service life and poor practicality. Utility Model Content

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a reasonable structural design. The upper surface of the holographic pattern layer and the upper surface of the corrosion-resistant layer are flush with the upper surface of the imaging layer. The reflective layer is a prism layer or a glass fragment layer.

The corrosion-resistant layer can protect the sides of the cold foil composite film, preventing moisture and acidic substances in the environment from entering the imaging layer and the holographic pattern layer from the sides of the cold foil composite film. The magnetic layer allows the cold foil composite film to be adsorbed onto the surface of ferrous or magnetic products, resulting in good wear resistance, good corrosion resistance, long service life, and good practicality.
