Standard POF is especially suitable for use as a folding film, because of its good opening; of course, it can also be used for monolithic film. The adaptability to the packaging machine is very good — it can adapt to most automatic and semi-automatic packaging machinery requirements, making it a very widely used and affordable product. Conventional thickness: 12um, 15um, 19um, 25um, 30um.
POF is mainly used for packaging regular and irregular shape products. Because of its non-toxic environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, tear resistance, heat shrinkage uniformity, and suitability for automatic high-speed packaging, it is widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, crafts, frames, wood products, toys, pesticides, daily necessities, food, cosmetics, canned beverages, dairy products, medicine, tape, and video products.
