What is the difference between the toughness of different materials shrink film

Our common shrink film material has PVC/PE/POF material, of course, there are some composite material shrink film such as BOPP, PET, etc., we focus on PVC/PE and POF material shrink film toughness what is different.

First of all, PVC shrink film material relative to POF and PE material is more brittle, which is also determined by its chemical properties, and PVC shrink film material is also better to distinguish because he touched the sound is relatively large, and PVC heat shrink film is also a cost-effective one of the three materials inside the shrink film, mostly used for industrial packaging, such as: windows and doors, plaster line, aluminum, etc.; PE and POF toughness is relatively high. POF toughness is better, the packaging out of the effect is also more beautiful, PE shrink film is most commonly used in drinks, pallets or large objects on the packaging, because of its toughness is better also has a certain gravity; POF and more high-end point, its thickness in 1.2-3C or so, the general demand for packaging is more delicate will use POF heat shrink film, for example: disposable dishes and chopsticks, milk tea, Cosmetic box packaging and so on.
