PVA film is water soluble, biodegradable, polyvinylalcohol (PVOH) film designed for various packaging applications, including detergents and cleaners, degreasers, concrete additives, pigments, biocides, water-treatment products, agricultural products and others.

PVA film has excellent organic solvent resistance, which allows pouches and bags to be used not only for dry powders, but also for liquid products. The film is also designed to offer good tensile strength, tear strength and puncture resistance. Products packaged in pva film can reportedly be thrown into a treatment area without removing the film.

After few minutes of immersion at the specified temperature, PVA film dissolves in water, reportedly leaving a harmless, non-toxic, aqueous solution of polyvinyl alcohol releasing the packaged product to do its work. Once the liquid solution of PVOH comes into contact with common microorganisms, such as those found in water-treatment plants, conversion to carbon dioxide and water takes place within about 30 days.

water soluble film for the smart and convenient packing and dosing of powders, tabs and granulates.

Water soluble film is a special protective film which made with water soluble polymer materials (PVA/PVOH) and through the production of a specific film forming process, we also called its PVA films. When the film soluble in the water, it can be degraded into harmless substances, so it is a kind of environmental friendly, resource-saving new high-tech materials.

Features:

• It can be soluble in the water and other components of the aqueous solution in accordance with the time required. The solution rate from 10 seconds to 20 minutes, deponds on different temperature from 4 to 80 centigrade.
• It will not set off a chemical reaction with mostly materials which packing in the film after solution, so the material physical and chemical characteristics will be remained.
• Water soluble film will discharged into the environment with water together after solution, it will biodegradation by the sunlight and a special bacilli , so it’s very friendly to the environment.
• Good leakproofness, stretchability, oil resistivity, anti-static and anti-corrosion makes it a perfect packing material.
