HGHL BOPP (Biaxially Oriented Polypropylene) Transparent Film
Description
Heat sealable transparent BOPP film with low coefficient of friction and low heat sealing threshold for high-speed 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 mechanical properties; intended for contact with food; both side low coefficient of friction; without coatings and primers.
