Suitable as a film for the packaging
There is excellent resistivity in regards to the pulling, tearing, and impact. Therefore, it is suitable as a film for the packaging to protect contents.
Good heat sealability
Because it is possible to seal at temperature (120-180) like the polyethylene film, it is possible to make bags easily.
Resistance to oils and chemicals
The film is not affected by oils and fats such as animal oils, vegetable oils, mineral oils, fats, organic solvents and the hydrocarbons and can not be penetrated by them. However, it sometimes dissolves in specific organic solvents such as the glycols, DMSO, the phenols.
Good gas barrier properties
It has an excellent gas barrier to oxygen, nitrogen, hydrogen, carbonic acid gas and so on, when the humidity is low. Moreover, it has an excellent fragrance preservation of the contents as well.
Good antistatic properties
Because it has a lot of hydroxyl groups in molecule, it does not take charges. Compared with the film which is made from the other synthetic resins it is difficult for the trouble caused by electrification to occur.
Because the adhesion with ink is great, gravure print and so on are beautifully completed.
