Bronzing, UV, polishing and other printed surface finishing process is widely used in portable paper bag production process. It greatly satisfies the people of the paper bag of fine, high-end pursuit. In the production process, we must also control the key points in these processes.

Handbag paper foil bronzing process and India compared to its strong sense of metal, consistency is good, bright color, three-dimensional sense of richer. The perfect bronzing effect depends on the bronzing temperature, pressure and speed of the organic coordination.

Portable paper bag bronzing operations should pay attention to the following factors affect the effect of hot stamping:

① flat surface printing products flatness;

② hot stamping products on the surface after the treatment process (film, oil, etc.);

③ the use of aluminum foil hot stamping suitability;

④ hot stamping plate and hot stamping machine status.

Hot stamping is a complex process technology, in the hot stamping process to fully consider the impact of these factors, it is possible to achieve a satisfactory hot stamping effect.

The surface of the portable paper bag polishing process mainly refers to UV glazing and ordinary glazing. The glazing process enables the printing material to maintain a good gloss and improve the surface resistance of the printed matter, especially UV glazing and local UV coating in the paper bag processing technology, the paper bag printing layer thick and dense, luster Rich moisture, printing theme highlights, strong sense of view.
