Advantages of PVOH Film


PVOH (Polyvinyl alcohol) film has several advantages that make it a popular choice for various applications. Some of the main advantages of PVOH film include:

1. Water Solubility: PVOH film is highly soluble in water, making it an excellent choice for applications where water dissolvability is desired. It is commonly used in single-use packaging for detergent pods, laundry bags, and water-soluble pouches for various chemicals.

2. Biodegradability: PVOH film is biodegradable and environmentally friendly. It breaks down into harmless components, reducing its impact on the environment compared to non-biodegradable materials.

3. High Tensile Strength: Despite its water-soluble nature, PVOH film exhibits good tensile strength, which makes it suitable for applications where some level of mechanical strength is required, such as in packaging or agriculture films.

4. Barrier Properties: PVOH film has good oxygen and aroma barrier properties, making it useful for preserving the freshness and extending the shelf life of sensitive products, such as food and pharmaceuticals.

5. Transparent and Glossy: PVOH film has excellent clarity and glossy appearance, making it an attractive option for packaging where product visibility is important.

6. Low Toxicity: PVOH is considered to be non-toxic and safe for use in various applications, including food packaging and pharmaceutical products.

7. Versatility: PVOH film can be easily processed and used in a wide range of applications, such as in the production of water-soluble bags, laundry pods, food packaging, agricultural films, and more.

8. Printable: PVOH film can be printed on using various printing techniques, allowing for branding and product information to be added to the packaging.

9. Temperature Stability: PVOH film retains its properties even at relatively low and high temperatures, making it suitable for applications with varying temperature requirements.

PVOH film also has some limitations, such as sensitivity to moisture, which may reduce its shelf life if not stored properly. However, its overall advantages make it a preferred choice for various applications where water solubility and biodegradability are desirable features.
