p0F heat shrinkable film--how to treat the surface of heat shrinkable film packaging?

Today the author and you are chatting about p0F heat shrinkable film-three ways of surface treatment of heat shrinkable film packaging 1. Corona treatment: discharge treatment to the surface of the film through high voltage electric charge, so as to achieve the purpose of strengthening the surface energy and surface tension . Corona treatment is generally carried out in the film manufacturing plant. Because the surface tension is time-limited, it is required to be strictly tested before printing. Therefore, some advanced equipment has a pre-press corona treatment device in order to print high-quality film products. 2. Printing treatment: Use chemical methods to change the surface characteristics of the film to make it suitable for ink printing or ribbon printing. 3. Surface coating: Use chemicals to coat the surface of the film to increase the surface tension and change the surface characteristics. Tag: p0F heat shrinkable film
