New Development of PET Film Sticker Printing
PET is a hard-to-attach material. Looking for a coating material that is completely attached to PET material, a coating with relatively high surface activity and easy ink adhesion is formed on its surface. PET has been a surface modification The main means of sex, the PET film processed by this method, commonly known as easy to follow PET, also called processing PET.
At present, compared with the domestic market, PET with better quality is generally selected, and then corona treatment and white electric oil are used to wipe to change its adaptability. For food-grade packaging, this treatment is very polluting. There are also many examples confirming that the quality of the PET film for easy adhesion is directly related to the surface printing activity, solvent resistance, transparency and other parameters of the coating.
At present, HZW-PETCOAT-1000 used by many companies is an aqueous PET treatment liquid, which can form a layer of transparent coating with very strong adhesion on the surface of PET material, which has excellent printability (almost can meet All UV-type, solvent-type and water-based ink adhesion requirements), has good water resistance and alcohol resistance. HZW-PETCOAT-1000 can be infinitely diluted with water, no harm to the environment and operators, and its best environmentally friendly product.
