With the increasing awareness of environmental protection in recent years, the environmental protection requirements for packaging materials are also increasing. The concept of sustainable packaging continues to gain popularity. POF shrink packaging is also affected by this, focusing more on reducing environmental impact, improving packaging efficiency, and reducing energy consumption. Therefore, the development trend of POF shrink film is mainly concentrated in the following aspects:

Thinning: further thinning based on ordinary POF shrink film to reduce the weight of POF shrink film used in unit packaging, thereby reducing the use of petrochemical products (polyethylene and polypropylene) in packaging.

Thickening: Produce thicker POF shrink film to replace part of the market for traditional blown shrink film.

Compared with the traditional blown shrink film, this POF shrink film has a thinner thickness, better strength, and transparency, and can also reduce the use of petrochemical products.

Low-temperature shrinkage: Lowering the shrinkage temperature can increase the packaging speed.

What is more important is to reduce the energy consumed during heating shrinkage, and at the same time can also reduce the energy consumption in the production process of POF shrink film to a certain extent.

In response to the above development trends, the production process, raw materials, and film structure of POF shrink film need to be adjusted accordingly.

Only when raw material suppliers and film manufacturers cooperate in depth can they continuously introduce new products and new applications that meet market demands.
