p0F heat shrinkable film--what is heat shrinkable film?

p0F heat shrinkable film--Heat shrinkable film is a relatively advanced packaging method. Heat shrinkable film packaging is widely used in food, ceramic products, tea sets, mechanical parts and other industries. Products packaged with heat shrinkable film can fully highlight The appearance of the product is improved, and the display, beauty and sense of value of the product are improved. At the same time, the heat shrinkable film packaging also has the characteristics of sealing, moisture-proof and pollution-proof. 1. Heat-shrinkable film structure The film structure of heat-shrinkable film packaging is similar to that of paper. The difference is that the surface of the film must be treated. 2. The principle of forming patterns on the printed matter by the surface treatment of the heat-shrinkable film packaging ink layer is penetration, volatilization, film formation and curing. However, due to the high film density, the ink only volatilizes and conjunctiva, and there is no penetration during the curing process, so the surface of the heat shrinkable film packaging needs special treatment. After treatment, the surface tension of the heat shrinkable film is increased to make the heat shrinkable film greater than the surface tension of the ink, so as to achieve the correct combination of the ink and the film material.
