Its density is 1.26-1.29g/cm3, refractive index is 1.52, there'll be a white light blue after evaporated by UV irradiation. Water absorbability is large, if immersed in water, it will dissolve. The moisture content of fiber can reach 30%-50%, and the moisture content at 65% RH and 25 C can also reach 4.5%.
Polyvinyl Alcohol is harmless to human with no odor, and friendly to the environment. It can be degraded into carbon dioxide and water in a short time and has the function of improving land.

2. How to keep ?
Application temperature15~33℃
Related humidityRH40~70%
Keeping temperature7~30℃
3. Features:
1) Non-toxic, tasteless, harmless, environmentally friendly, not cumulative;
2) Good toughness, high tensile strength, tear strength is the best of all types of thin films, the biaxial tensile strength is excellent;
3) Good weather resistance and good oil resistance, long service life;
4) High transparency and gloss, which are better than other thin films;
5) Good moisture permeability, similar with cellophane, will not produce droplets (fog drop) when packaging heat or wet items;
6) Excellent oxygen-resistance, especially in the dry conditions. Its oxygen permeability coefficient is the lowest in all kinds of resin film;
7) Strong anti-static, it won't lower its plasticity or cause static dust in the process of packaging products;
8) Good printability, excellent water color and ink printing, it can be used for water transfer printing.PVA Film manufacturers
