PVA Film
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
Polyvinyl alcohol (PVA) films are made primarily from polyvinyl alcohol (PVA), with additives such as modifiers added, and processed through a specialized process. PVA films are biodegradable materials used in packaging and various other applications. They dissolve in water without leaving harmful residues, making them an environmentally friendly alternative to traditional plastics. PVA (polyvinyl alcohol) films are revolutionizing the way companies think about packaging and material solutions. These dissolvable films, with their unique environmental performance, offer a sustainable alternative without compromising product quality.

| PVA is produced with calcium carbide as raw material. After calcium carbide reacts with water to form acetylene, acetylene synthesizes with acetic acid to form vinyl acetate, then methanol is used as the solvent to polymerize, Through alcoholysis, poly-vinyl acetate changes to PVA. After being crushed and dried, it becomes finished product. | |||
General Properties
Polyvinyl alcohol film: Density 1.26-1.29 g/cm³, refractive index 1.52, emits bluish-white light upon exposure to ultraviolet light. It is highly hygroscopic and dissolves in water. The fiber moisture content can reach 30%-50%, and can even reach 4.5% at 65% RH and 25°C. It is permeable to water vapor but poorly permeable to alcohol vapor. It is impermeable to organic solvent vapor, inert gases, and hydrogen.
Applications
1. Instant-dissolving film: Lining bags for pesticide and chemical product packaging, cement additive packaging, hospital detergent packaging, and garbage bags.
2. Medium-dissolving film: Food and cosmetic packaging, supermarket shopping bags, air cushions, and anti-static packaging for electronic products.
3. Insoluble film: Packaging for chemical raw materials and intermediates, daily necessities, pharmaceuticals, and toys.
4. Specialty film: Polarizing film, automotive film, windshield lamination, and sanitary material manufacturing.
