Product Introduction
Environmentally friendly POF heat shrink short film is the abbreviation for biaxially oriented polyolefin shortening film. It is a new type of environmentally friendly shortening film widely used and rapidly developing in the world. This product adopts a special process of advanced bi-directional stretching three-layer melt co extrusion. Produce soft shortening films with high transparency, high shortening rate, high toughness, high heat sealing function, excellent anti-static and cold resistance, and safety and reliability.
Product Usage
Widely used in the packaging and collective packaging of products in various industries such as food, cosmetics, gifts, pharmaceuticals, stationery, toys, audio and video products, electronics, wood products, plastic hardware, daily necessities, etc. This product is suitable for semi-automatic or fully automatic shortening packaging machines.
