Cross linked POF shrink film is a kind of technology and performance improvement of ordinary shrink film, shrink film is mainly used in the vacuum packaging of meat, fish, seafood products, using its high shrinkage and high barrier performance, so that the shelf life of food has been extended.
In the process of use of shrink film will always encounter a series of packaging problems, under this premise, pof Cross linked shrink film should be born. What are the common problems of shrink film? How does the POF film overcome these problems?
One: atomization, During the packaging process, the temperature of the shrink film is too high, or the packaging speed is too fast, so that the surface of the shrink film produces mist. However, the phenomenon of product fogging rarely occurs during the use of the cross linked POF shrink film, because the temperature shrinkage range of the POF film is very large, and the close-fitting effect with the product can be achieved, without a particularly high temperature.
Two: Tensile fracture, to achieve a better packaging effect, the shrink film will increase the tensile force during use. When the tensile force that the shrink film can bear is exceeded, the stretch film will break, but the strength and durability of the POF film are stronger than ordinary Shrink film, not easy to break.
Three: air can not exclude, During the packaging process, the air cannot be discharged from the package. If the air is discharged from the shrink film by adjusting the temperature of the package, other problems will occur, such as the impact on the contents of the package. This phenomenon does not occur during the use of POF-resistant shrink film. The close-fitting effect is tight without gaps.
The cross linked POF shrink film provided by Sunkey Packaging for Tyson Foods has been widely used in the market. Our mature production technology welcomes customers in need to negotiate with us.
