Similarities and differences between PVC and POF heat shrinkable film

    POF heat shrinkable film is the abbreviation of biaxially oriented polyolefin shrink film. It is a new type of environmental protection shrink film which is widely used and developing rapidly in the world. What is the difference between POF and PVC heat shrinkable film?

similarity

1. They all shrink when heated.

2. It's all transparent.

3. All can be made into shrink bags.

4. All can be shrunk with a shrinking machine.

different

1. The shrinkage temperature of 1.PVC should reach 100-120 degrees, and that of POF should reach 140-160 degrees.

2. As the shrinkage temperature requirements are different, PVC can be shrunk with a household hair dryer, and POF should at least use a hot air gun. Therefore, those who use the hair dryer at home to achieve the contraction effect will buy heat shrinkable film made of PVC and heat shrinkable bags.

3. The finished 3.PVC heat shrinkable film is tubular, and the finished POF heat shrinkable film is folded in half and monolithic, not tubular.

4.PVC can be made into shrink slide and arc bag with both ends connected, but POF is not easy to make now. Two-end shrink cut pieces and circular arc bags.
