Q: What are the advantages compared with BOPP cold film?
A: BOPP cold film also be known as WATER BASE FILM. The different point is in the use of adhesive and production process. BOPP thermal lamination film uses EVA (hot melt adhesive film), while Cold film uses WATER BASE GLUE. Both common point is the use of BOPP. The advantages compared with BOPP cold film follow as below:
First, due to the lamination process of thermal lamination film does not produce any harmful substances, therefore, it is more environmentally friendly.
Second, lamination process is simple which doesn’t need to adjusted against the glue like BOPP cold film. No controlling amount of spread in the production process, no drying on the adhesive. Only need to control the temperature, pressure and speed, no need to clean gluing mechanism.
Third, the phenomenon of bubbles, wrinkles, stripping can not be generated in the production so that the products would be in higher quality.
Fourth, it can adapt to a wide range of film equipment.
Fifth, due to the absence of organic solvents in the lamination process of thermal lamination film, it can effectively prevent the occurrence of fire accidents, and the safety factor is higher.
Sixth, high production efficiency.
