BOPP white film
1. Description of BOPP white film
Silver whiteness with glossy pearl, can be laminated with CPP or PE film after been printed, For food, chopsticks, gifts, soap package and freeze cold drink such as ice cream. Thermal label, sweet food, biscuit, snack food.
2. Characteristics of BOPP white film
(1)High stiffness , low static property , suitable for high speed laminating processing
(2) Good machineability with good lap heat sealability, printing and laminating property.
(3)Added brightness and pearl luster as 5-layer cavitated film provide attractive eye appealing
(4)Uniform and stable unit weight.
