Compared with another masterbatch, BOPET masterbatch has a higher melting index, better transparency, and heat resistance. The selection of suitable masterbatch plays an important role in the quality of BOPET films.
The slip masterbatch added in BOPET masterbatch is usually silicone oil or amide. Silicone oil slip masterbatch has excellent high-temperature resistance and low friction coefficient, but it is easy causes surface pollution and shedding, so it should be carefully selected.
Amide slip masterbatch has better wear resistance and transparency, but the heat resistance is poor, and can not meet the requirements of a high-temperature environment.
