Information

In recent years, in the post-press film market, a low-cost non-adhesive film was born. The film shocks the pre-coating film with the advantage of low price. How much market share can the non-adhesive film replace the pre-coating film? Next, we compare the economical pre-coating film with non-adhesive film. The economic pre-coating film thickness is 16-18 microns, while the non-adhesive film thickness is 16-20 microns. The pre-coating film is formed by extrusion composite equipment. The non-adhesive film is processed in one time on the biaxially stretched BOPP production line. Based on the difference of equipment, 1. Extrusion recovery. The bonding equipment can smoothly coat the hot melt adhesive EVA with excellent performance and low price on the surface of BOPP as adhesive; 2. Bi-directional stretching BOPP production line is difficult to do this, because EVA lacks stretching performance and is very sticky and easy to stick to guide rolls. The hot melt adhesive with high melting point and not easy to stick will be chosen as the production without film. Adhesives, because of the different use of adhesives, reduce the adhesiveness of non-adhesive film to paper ink. Therefore, non-adhesive film is only suitable for light-color printing film coating field which requires less adhesiveness, or it is difficult for non-adhesive film to enter the high-end pre-coating market.
