Poval Film

"Kuraray Poval Film" is produced from polyvinyl alcohol (PVA) resin. "Kuraray Poval Film" was commercialized at Kuraray Saijo Plant in 1962. Over the years, capacity expansion and efforts to develop new applications ensured that was able to satisfy a broad spectrum of demand. Many applications such as packaging for shirts and knit garments; polarizing panels for liquid crystal display used in notebook PCs and word processors; mold during the thermosetting stage for fiber-reinforced plastics; and sheeting for agricultural use. Thanks to the properties of its base material, PVA, also has water-soluble Film grades. Owing to this distinctive feature, many new uses have been developed.

"Kuraray Poval Film" is made of PVA (Polyvinyl Alcohol) Resin. PVA (Polyvinyl Alcohol) is a unique functional resin that Kuraray first industrialized in the world as a pioneer. Its water-solubility is the most particular characteristic, even though PVA is one of the synthetic high polymers.

PVA has variety of characteristics, such kind of adhesiveness, Film formation property, emulsifying property, oil-resistant ability. By utilizing these kind of properties, PVA has been used in various industrial applications, such as the synthetic fiber vinylon, and Poval Film, warp sizing, paper sizing, stabilizer for the PVC polymerization etc.

The Kuraray water soluble Poval Film has unique performance and variations ,comes from our PVA resin,composition,and Film making technique. Kuraray is also PVA Resin manufacture and can design and make a unique PVA for the Film.

Soluble with water. The Kuraray selects the raw materials which are the optimal for each use, from the cold water soluble type to the hot water soluble type and assorts the Film with all kinds of brands.

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 temperatures 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.

Good printability. Because the adhesion with ink is great, gravure print and so on are beautifully completed.
