Developmental and technical information

Film coating/compounding

n To add an anti-blocking,

anti-adherence, and release improving effects
When Techpolymer is compounded into film or coated on film, it makes the coat surface uneven, which provides an anti-blocking effect to the film.
Compared with inorganic materials (e.g. silica), Techpolymer has a higher compatibility for base materials, which decreases scratches on film and anti-blocking agent loss. Grades with a sharper size distribution are being developed to meet the need of "particles of more even size."
