Description

Heat sealable transparent BOPP film with a standard coefficient of friction and low heat sealing threshold for packaging machines. For high quality rotogravure and flexographic printing and lamination. The main advantages are: A wide range of heat sealing; contains slip-antistatic and antiblocking additives; excellent optical properties; good physical and mechanical properties; intended for contact with food; standard coefficient of friction; without coatings and primers.
