25 μm Polyvinyl alcohol (PVA) film, water soluble, for detergent pods, food, agricultrual packaging, prniting etc.
The application scenarios that 25 micron Polyvinyl alcohol (PVA) film, the water soluble film has are:
Dissolvable Packaging: PVA film is commonly utilized for dissolvable packaging applications. It can be employed to create pouches, sachets, or wrapping material that readily dissolves upon contact with water, enabling easy access to the contents inside.
Cleansing and Sanitizing Products: PVA film finds extensive use in the manufacturing of cleansing and sanitizing products. It is frequently employed to produce detergent pods or capsules, where the film acts as an efficient and convenient means of delivering the cleaning agents. The film dissolves in water during the washing or cleaning process, releasing the potent cleansing solution.
Controlled Release in Agriculture: PVA film is used 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 ingredients upon contact with water.
Supportive Medium in Embroidery and Sewing: PVA film is commonly utilized as a supportive medium in embroidery and sewing projects. It can be employed as a stabilizer or backing material for delicate fabrics, providing essential support during the stitching process. Once the embroidery or sewing is complete, the film can be dissolved through washing, leaving behind a pristine and flawlessly finished product.
Water-Soluble Pharmaceutical Packaging: PVA film finds application in the pharmaceutical industry for water-soluble packaging solutions. It can be used to create dissolvable films or tablets that readily dissolve upon contact with moisture, facilitating convenient and precise dosage administration.
Convenient Personal Care Applications: PVA film is employed in various personal care applications. It can be incorporated into water-soluble packaging for single-use products like bath salts, bath oils, or facial masks, providing a convenient and mess-free experience. The film dissolves in water, allowing for effortless utilization of these personal care items.
Please note that the specific suitability of 25 μm Polyvinyl alcohol (PVA) film for a particular application should be verified based on industry requirements, manufacturer guidelines, and customization options available.
