PET is a hard-to-adhere material, looking for a coating material that is completely attached to the PET material and forms a coating with a relatively high surface activity and easy ink adhesion on the surface, which has always been a surface modification of PET. The main means of sexuality, the PET film treated by this method, commonly known as easy to follow PET, also known as PET treatment.
At present, compared to the domestic market, generally speaking, PET will be selected with better quality, and then corona treatment and white oil can be used to change its adaptability. This is very serious for food-grade packaging. There are also many real examples.
The quality of the easily-attached PET film is directly related to the parameters such as surface printing activity, solvent resistance, and transparency of the coating.
At present, some companies use HZW-PETCOAT-1000 as an aqueous PET treatment solution, which can form a very firm adhesion transparent coating on the surface of PET material, while having excellent printability (almost all The requirements for the attachment of UV-type, solvent-based and water-based inks), together with good water resistance and alcohol resistance. HZW-PETCOAT-1000 can be infinitely diluted with water. No harm to the environment and operators. Its best environmental product.
