The application scenarios that 30 micron polyyvinyl alcohol (PVA) film, the water soluble film has are:
Soluble Packaging: PVA film is commonly used for soluble packaging applications. It can be employed to create pouches, sachets, or wrapping material that completely dissolves when exposed to water, allowing for easy access to the contents inside.
Cleansing and Disinfecting Products: PVA film finds extensive use in the manufacturing of cleansing and disinfecting products. It can be utilized to produce dissolvable pods or capsules containing cleaning agents or disinfectants. The film readily dissolves in water, releasing the active ingredients for effective cleaning and disinfection.
Controlled Release in Agriculture: PVA film is employed in the agricultural industry for controlled release applications, such as slow-release fertilizers or pesticides. The film can be formulated into water-soluble pouches or capsules that gradually dissolve, ensuring a controlled and sustained release of the active substances upon contact with water.
Supportive Medium for Crafts: PVA film is commonly used as a supportive medium in various crafting projects. It can serve as a backing or stabilizer for delicate materials, providing support during artistic processes such as painting, collage, or mixed media. Once the project is complete, the film can be dissolved, leaving behind the finished artwork.
Water-Soluble Medical Packaging: PVA film finds application in the medical field for water-soluble packaging solutions. It can be used to create dissolvable films or pouches for medical devices or single-use supplies. The film readily dissolves upon contact with moisture, facilitating convenient and hygienic access to the contents.
Sustainable Hygiene Products: PVA film is employed in the production of sustainable hygiene products. It can be used to create water-soluble wipes or personal care items, providing a convenient and eco-friendly alternative to traditional disposable products. The film dissolves in water, minimizing waste and environmental impact.
Please note 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.
