30 micron Polyvinyl alcohol (PVA) film is a water-soluble film that has a wide range of applications.
Here are some examples:
1. Soluble Packaging:
PVA film is commonly used in the creation of soluble packaging materials such as sachets, pouches, or wrapping material that dissolves
completely in water upon contact, providing easy access to the contents inside.
2. Cleansing and Disinfecting Products:
PVA film is widely used in the manufacturing of cleaning agents and disinfecting products.
It is formulated into dissolvable capsules or pods containing active ingredients that release upon dissolving in water for effective cleaning
and disinfection.
3. Controlled Release in Agriculture:
The PVA film is used in the agricultural industry for controlled release applications such as slow-release fertilizers and pesticides.
It is formulated into water-soluble pouches or capsules that dissolve gradually; as a result, the active substances are released slowly over time,
ensuring a controlled and sustained release of active substances upon contact with water.
4. Supportive Medium for Crafts:
PVA film is a great supportive medium and commonly used in various art and crafting projects as backing or stabilizer for delicate materials.
It provides support during the artistic process and can be dissolved upon project completion, leaving behind the finished artwork.
5. Water-Soluble Medical Packaging:
PVA film is used in the medical field for water-soluble packaging solutions. It is formulated into dissolvable films or pouches for medical
devices or disposable supplies. The film readily dissolves upon contact with moisture, enabling hygienic access to the contents.
6. Sustainable Hygiene Products:
PVA film can be used to create eco-friendly and sustainable hygiene products such as water-soluble wipes, personal care items, and other
disposable items. The film dissolves in water, minimizing waste and environmental impact.
It's worth noting that the suitability of 30 μm Polyvinyl alcohol (PVA) film for specific applications should be verified based on industry requirements, manufacturer guidelines, and customization options available.
