Introduction to POF Heat Shrink Film Thickness

Environmentally friendly POF shrink film, short for biaxially stretched polyolefin shrink film, is a rapidly developing new type of environmentally friendly shrink film widely used in the world today. So, what thicknesses can POF heat shrink film provide? Let's explore that today.

1. POF heat shrink film products are produced using a special process of biaxially stretched three-layer or five-layer co-extrusion. They offer high transparency, high shrinkage rate, high toughness, excellent heat sealing properties, anti-static properties, excellent cold resistance, and safe and reliable flexible shrink film.

2. POF heat shrink film is mainly used for packaging products with regular and irregular shapes. It is known for its environmental friendliness, high transparency, high shrinkage rate, good heat sealing properties, high surface gloss, good toughness, high tear resistance, uniform shrinkage, and suitability for fully automatic high-speed packaging.

3. The standard thicknesses of POF heat shrink film include 12um, 15um, 18um, 19um, 20um, 23um, 25um, 30um, and other specifications. Many people believe that the choice of shrink film thickness is related to the weight of the product to be shrunk, but this is not the case.

4. The determination of shrink film thickness mainly depends on the smoothness of the surface of the item being shrunk and the shape of the packaging. For example, for packaging standard-sized books or paper boxes, a film thickness of 2 microns is sufficient. However, for packaging items like air conditioning ducts or car exhaust pipes, the shrink film should be at least 2.5 microns thick.
