Embroidery Laundry bags Agriculture and chemical packing Detergent/dyes,bowl cleaner and cement additive packing Water-transferred printing Biodegradable Basic Properties Thermal Stability, Thermal Degradability Solubility Differences Grade-by-grade Water solubility Resistance to Oils and Organic Solvents Strength and Weathering resistance Good heat sealability and adhesiveness Good gas barrier properties Good printability

Good gas barrier properties     Water-soluble PVA film has an excellent gas barrier to oxygen, nitrogen, hydrogen, helium, argon, carbonic acid gas and so on when the humidity is low, but it permit moisture and NH3 to penetrate. Moreover, it has an excellent fragrance preservation of the contents and can keep products moisture and fresh as well.
