Blown-up polypropylene film (BUPP)
Aluminum-free! Achieving retort pouches compatible with metal detectors and microwaves!
The product is a multilayer polypropylene film manufactured using an air-cooled upward multi-layer inflation method. Our expertise in coloring is, of course, available. Due to its excellent heat resistance and rigidity, it can be used as a sealant for retort and standing pouches. Compared to standard retort CPP, it has greater mechanical strength, allowing for thinner materials. With a three-layer structure of white-black-white "BUPP-WBW" and three-layer concrete "BUPP-3W," it provides light-blocking and opacity that cannot be achieved through printing. 【Features】 ■ "High-strength, low-odor film" created through upward air-cooled inflation ■ "Light-blocking and opacity" equivalent to aluminum foil ■ Safety for food packaging ■ Patent obtained for unique film manufacturing method *For more details, please refer to the PDF document or feel free to contact us.
