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, and it can adapt to most automatic and semi-automatic packaging machinery requirements — a very widely used and affordable product. Conventional thickness: 12um, 15um, 19um, 25um, 30um.
POF is mainly used for packaging regular and irregular shaped products. Because of its non-toxic environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, tear resistance, and heat shrinkage uniformity, it is suitable for automatic high-speed packaging. 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.
