30μm Polyvinyl Alcohol Film
30μm Polyvinyl alcohol (PVA) film is a water-soluble film with diverse industrial applications across multiple sectors.
Key Applications
- Soluble Packaging: Used for sachets, pouches, and wrapping materials that dissolve completely in water for easy content access
- Cleansing and Disinfecting Products: Formulated into dissolvable capsules or pods that release active ingredients upon water contact
- Controlled Release in Agriculture: Enables slow-release fertilizers and pesticides through gradual dissolution for sustained active substance delivery
- Supportive Medium for Crafts: Provides backing or stabilization for delicate materials in art projects, dissolving upon completion
- Water-Soluble Medical Packaging: Used for dissolvable films and pouches for medical devices and disposable supplies
- Sustainable Hygiene Products: Creates eco-friendly wipes and personal care items that minimize environmental impact
Note: Application suitability should be verified based on industry requirements, manufacturer guidelines, and available customization options.
