by：POLYVA 2021-12-09

Since PET is a polar film and BOPP is a non-polar film of the two kinds of films, there are also certain requirements for the polarity of the glue. According to the principle of similar polarity, the stronger the adhesive force, if the same glue is required Composite PET film can also composite BOPP film, and the polarity of the glue cannot be too biased towards one end. Therefore, when evaluating the glue performance, a comprehensive comparison must be made. If the adhesion performance of the PET film is very good, it does not mean that it can also perform very well on BOPP, and vice versa. Note that: For films of different brands or batches, small bright spots will appear when they are compounded. The corona value of the film will gradually fade with the extension of the storage time and the change of the storage environment, especially in wet conditions, so it needs to be checked before use.
