Due to below Unique Properties of Polyvinyl Alcohol (PVA/PVOH), it can dominate the Water-Soluble and Packaging Film Industries
1.Complete Water Solubility & Controlled Dissolution
Depending on its degree of hydrolysis and molecular weight, PVA/PVOH can be engineered to dissolve rapidly in cold water (20℃), warm water, or require hot water (>85℃). This controlled solubility allows manufacturers to tailor dissolution rates precisely to end-user requirements.
2.Superior Gas and Aroma Barrier Performance
PVA/PVOH features exceptionally low oxygen, nitrogen, and carbon dioxide permeability-far outperforming standard polyolefin films. It also provides excellent resistance to oils, greases, organic solvents, and petroleum-based products.
3.Outstanding Mechanical Strength and Transparency
PVA films exhibit high tensile strength, flexibility, and puncture resistance. When cast or extruded properly, they offer crystal-clear optical transparency, ensuring premium product presentation.
4.Biodegradability and Eco-Friendliness
Unlike non-degradable plastics that persist in ecosystems as microplastics, PVA is completely biodegradable. When exposed to water and natural microorganisms, it breaks down harmlessly into carbon dioxide (CO₂) and water (H₂O).
Possess these unique characteristics, PVA PVOH resin like the grade BP05(205/0588), BP17(217/1788) is widely processed into advanced films utilized across multiple global industries:
1.Unit-Dose Household Detergent Pods
Partially hydrolyzed PVA grades are extensively used to manufacture water-soluble pods for laundry detergents and automatic dishwashing tablets. The film dissolves instantly upon contact with water in the washing machine, eliminating chemical handling risks and plastic waste.
2.Agrochemical Packaging Sachets
Porous and chemical-resistant PVA films safely encapsulate pre-measured agricultural pesticides, herbicides, and fertilizers. Farmers can drop the entire sealed sachet directly into spray tanks, preventing direct dermal contact with concentrated toxic chemicals.
3.Infection Control & Medical Laundry Bags
Fully hydrolyzed or modified hot-water-soluble PVA films are used to package contaminated hospital linens. Nurses can place soiled textiles directly into industrial washing machines without opening the bags; the film dissolves completely in hot water during the wash cycle, preventing pathogen exposure.
4.Specialty Release and Embroidery Films
PVA films serve as temporary backing materials in textile embroidery and as specialized release films in the production of solid surface materials and composite plastics due to their clean wash-away nature.
