Polyvinyl alcohol film (PVA for short), the density of polyvinyl alcohol film is 1.26-1,29g/cm3, refractive index is 1.52, after ultraviolet irradiation basket white light. Absorbent, can dissolve in water. The moisture content of the fiber can reach 30%-50%, and the moisture content can reach 4.5% at 65%RH, 25 ℃. It can penetrate water vapor, but it is difficult to penetrate alcohol vapor, more can not penetrate organic solvent vapor, inert gas and hydrogen gas. The barrier property of polyvinyl alcohol film is even better than vinylidene chloride film. PVA is the only vinyl polymer that can be used by bacteria as a carbon source and energy. Under the action of bacteria and enzymes, it can degrade 75% in 46 days. It belongs to a kind of biodegradable polymer material, which can be large-scale produced by non-oil routes with low price and excellent oil resistance, solvent resistance and gas barrier performance.
Polyvinyl alcohol is non-toxic to human body, tasteless, harmless, and the natural environment has a good affinity, no accumulation, no pollution.
Polyvinyl alcohol high barrier composite film, based on polyethylene plastic as the base material, the modified water-soluble liquid polyvinyl alcohol coated on the base material to form a film with high barrier property. Because polyvinyl alcohol high barrier composite film has good barrier performance, and meets the requirements of environmental protection, so the market prospect of this packaging material is very bright, there is a broad market space in the food industry.
Water-soluble PVOH film and water soluble release film are made from water soluble polymers, having the appearance of a common plastic film. It has unique characteristic of completely dissolving in water at room temperature. The dissolved film disappears in water like sugar or coffee and the ingredients of the film change their appearance but remains present as dissolved solids in water.
The rate of dissolution depends on agitation, water temperature, amount of water and thickness of the film. The PVOH has proved to be a revolutionary film with its multiple uses which has been acknowledged and hailed by not only satisfied users but also ENVIROMENTAL PROTECTION AGENCY strongly recommends in packing agriculture chemicals and pesticides in this water soluble film as it is completely biodegradable and safe for environment and with time to come the use of this film not only going to increase but also indispensable because of its biodegradability, eco-friendly with multiple uses.
