Description

Transparent, antifog, both side corona treated BOPP film, for high quality rotogravure and flexographic printing, for the production of packaging for salads and vegetables. The main advantages are: One side has an antifog properties; Another side for printing; antifog properties for 6 month; low coefficient of friction on both sides; both side heat sealable; high optical and physical-mechanical properties; contains a slip-antiblock and special additives; intended for contact with food; without blocking in unwinding; without coatings or primer.
