Product Applications
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.

Frequently Asked Questions
Q
What thicknesses are available for Standard POF Shrink Film?
Standard POF Shrink Film is available in five conventional thicknesses: 12um, 15um, 19um, 25um, and 30um. Each gauge offers different tensile, tear, and seal strength values to suit various packaging needs.
Q
Is POF Shrink Film safe for food and consumer product packaging?
Yes. POF (Polyolefin) Shrink Film is non-toxic and environmentally friendly, making it widely used for food packaging, dairy products, beverages, medicine, and cosmetics, among other consumer goods.
Q
What types of packaging machines is POF Shrink Film compatible with?
POF Shrink Film has excellent adaptability to packaging machinery and is compatible with most automatic and semi-automatic packaging machines. It supports high-speed packaging operations and works well as both a folding film and a monolithic film.
Q
What are the shrinkage rates of POF Shrink Film at different temperatures?
Free shrinkage rates vary by temperature. At 100°C, TD shrinkage is 23% and MD is 32%. At 130°C, TD reaches 67% and MD reaches 68%. Higher temperatures result in greater shrinkage, allowing tight conformity to product shapes.
Q
What industries and products can POF Shrink Film be used for?
POF Shrink Film is suitable for a wide variety of industries including automotive supplies, electronics, stationery, books, toys, crafts, wood products, food & beverage, dairy, cosmetics, medicine, and more. It is ideal for packaging both regular and irregularly shaped products.
Q
What optical properties does POF Shrink Film offer?
POF Shrink Film delivers outstanding optical performance. For example, the 12um gauge achieves a haze of just 2.1%, clarity of 98.5%, and gloss of 88.0% (at 45°). These properties ensure excellent product visibility and an attractive presentation on store shelves.
