    How do we Know if POF Shrink Film is Environmentally Friendly?

    Feb. 11, 2020

    First of all, the country is very strict about environmental protection. Especially in the packaging industry, many manufacturers are stopped because they fail to meet environmental protection requirements. Now many places do not allow the phenomenon of environmental pollution to occur again, and strictly require the factory to meet environmental standards. So what I want to say now is whether the POF shrink film is environmentally friendly, so follow the POF Shrink Film Manufacturer to continue looking down.

    POF Shrink Film

    POF Shrink Film is now widely used in people's lives. I believe everyone is familiar with him, because there are too many products that he can package, and people have chosen him because of his many benefits. POF shrink film is different from fresh-keeping film, which is mainly used in the transportation and sales of products, which can stabilize, cover and protect the product; while fresh-keeping film is mainly used for fresh-keeping food, regardless of their similarity, the benefits of POF are much greater.

    The reason why POF is environmentally friendly is that it uses linear low-density polyethylene as the middle layer (LLDPE), co-polypropylene (pp) as the inner and outer layers, plasticized and extruded through three extruders, and then formed through the die. Film bubble inflation and other special processes. The full name of POF is a multi-layer co-extruded polyolefin heat shrinkable film. It adopts a special process of advanced biaxial stretching and three-layer melt co-extrusion to produce high transparency, high shrinkage, high toughness, high heat sealability, antistatic, and cold resistance. , Safe and reliable soft shrink film. Although these chemical names are not particularly known, the properties of POF are probably known. POF heat shrinkable film is now a food-grade packaging bag, because of its shrinkage rate and temperature can be well controlled, fresh vegetables and fruits can be used for packaging.

    Nowadays, packaging is inseparable in various industries. The development of the economy has made the current packaging industry grow rapidly, especially the POF shrink film is far ahead of other shrink films. Different products also require different packaging to attract people's attention. .

    There are many types of environmentally friendly shrink films, and the methods of use are also different. The following is the experience that I personally summarized for you to share.

    POF shrink film has high transparency, environmental protection, strong corrosion resistance, easy to shrink and so on. Many people do not know how to shrink to have a good effect. The key reason is that they have not mastered a good method. The shrinking temperature of POF shrink film is between 140 ~ 160, which is determined according to the thickness and size of the bag.

    Our company also has POF Printing Film on sale, welcome to consult.
