40 μm Polyvinyl alcohol (PVA) film, water soluble, for detergent pods, food, agricultrual packaging, prniting etc.
Polyvinyl alcohol (PVA) film is a water-soluble, biodegradable film that is mainly used for various packaging applications.
Some of the main uses of PVA film include:
1. Detergent pods:
One of the most common applications of PVA film is in the production of detergent pods,
where the film is used to encase the detergent formula. The PVA film dissolves in water,
releasing the detergent and reducing plastic waste.
2. Food packaging:
PVA film is used in food packaging applications to provide a protective barrier and extend the
shelf life of perishable food items. The film has good oxygen barrier properties that reduce the
presence of air in packaging, improving the longevity and freshness of the food items.
3. Agricultural packaging:
PVA film is also used in agricultural packaging, providing a protective barrier for sensitive plants,
fruits, and vegetables. The water-soluble property of PVA film ensures that it does not leave any harmful
residue after use, making it safe for the environment.
4. Printing:
PVA film is also used as an inkjet printable media for fine art printing and high-quality graphics industry.
5. Water treatment:
PVA film is used for the production of pharmaceutical and medical products, as well as water treatment purposes.
PVA film is a versatile material used in a wide range of packaging and related industries due to its unique properties of
being readily soluble in water, biodegradable, and non-toxic.
PVA film has several advantages over other biodegradable films. Some of the significant advantages are:
1. Water-solubility:
PVA film is fully water-soluble, meaning it can dissolve completely in water, which is not the case in other biodegradable films.
This property makes PVA film an ideal solution for single-use items, such as disposable products in hospitals.
2. Biodegradability:
PVA film is biodegradable and breaks down into biologically benign substances such as carbon dioxide (CO2) and water (H2O)
through microbial digestion. This property makes PVA film highly environmentally friendly.
3. High strength:
PVA film has excellent mechanical properties such as high tensile strength and good puncture resistance,
enabling it to handle challenging packaging applications.
4. Versatility:
PVA film has diverse applications, including in food, consumer goods, and agricultural industries.
5. Cost-effectiveness:
PVA film is cost-effective, making it a practical and affordable alternative to non-biodegradable films.
Overall, PVA film offers a unique set of advantages that make it a preferred choice for various industries.
Its strength, biodegradability, versatility, and cost-effectiveness make it a desirable alternative to non-biodegradable films.
Reference Value for Water Solubility Performance
Classification | Test item | ||
| Water temperature (℃) | Splitting time (min) | Dissolution time(min) | |
Water-soluble bags | 45+2/-0 | ≤0.5 | ≤6.0 |
