Introduction to PVA water soluble film
Introduction
PVA water soluble film is a kind of polymer material. Its basic component is polyvinyl alcohol . Because of its good biodegradability, high transparency and a wide range of applications, it is widely used in pharmaceutical packaging, food packaging, building waterproof and other fields.
Polyvinyl alcohol (PVA) film, density 1.26-1,29g/cm3, refractive index 1.52, emitting blue and white light under ultraviolet irradiation. This product has water absorption, can be dissolved in water, fiber moisture content can reach 30%-50%, at 65%RH, 25℃ environment moisture content can also reach 4.5%. It can penetrate water vapor, but it is difficult to penetrate alcohol vapor, much less organic solvent vapor, inert gases, and hydrogen gas. The barrier performance of polyvinyl alcohol film is even better than that of vinylidene chloride film.
Benefits
This kind of film has several benefits for packaging applications. The film is strong, flexible, and thoroughly water soluble, making it ideal for various applications. At the same time ,the film is also biodegradable. Which t can be degraded into CO2 and H2O by microorganisms in water or soil .Additionally, the film is non-toxic and free from plasticizers and other chemicals, making it safe for use with food products.
Polyvinyl alcohol itself has solvent resistance, gas resistance, high transparency, antistatic and other excellent qualities. It is green environmental protection materials, in Europe, the United States, Japan and other countries have been recognized by the national environmental protection department, the third party test shows that polyvinyl alcohol biological oxygen consumption (BOD) is much smaller than starch.
Biological tests show that polyvinyl alcohol is non-toxic, will prevent the growth of microorganisms and reproduction, has no impact on solid waste treatment and environmental health, polyvinyl alcohol can almost be completely decomposed, and after entering the soil, there is the effect of improving soil.
Lastly, water-soluble film is highly versatile. It can be used for various packaging applications, including food products, pharmaceuticals, health care products, etc. It is also easy to use, as the film can be cut, heat-sealed, or glued together.
Conclusion
It is a revolutionary new technology that has revolutionized the packaging industry. They are completely water soluble. This type of film has many benefits for packaging applications, including being strong, flexible, and water-soluble. Additionally, it is environmentally friendly, cost-effective, and versatile. For all these reasons, it is an ideal choice for various packaging applications. applications.
How to use PVA water soluble film
PVA Water-soluble film can be an excellent way to preserve and protect your items. Whether you are an artist looking to protect your artwork, a librarian looking to save your books, or a hobbyist looking to preserve your collection, it can be a great way to do it.

Potential challenges
As technology continues to improve and develop, so do the products available on the market. One such product is PVA water-soluble film, designed to dissolve in water, making it easier to use and dispose of. This is perfect for various applications, from agricultural irrigation to food packaging.
Despite its many advantages, using PVA water-soluble film isn’t without its potential challenges. This blog will explore common issues and troubleshooting solutions to help you get the most out of your product.
Common Issues
The most common issue with PVA water-soluble film relates to its solubility . Over time, the film can become less soluble, meaning it may not dissolve as quickly as it should. This can lead to many problems, from reduced irrigation efficiency to poor water penetration.
Another issue that can arise is related to the film’s strength. It is a thin material that can be prone to tearing and puncturing. This can happen due to mechanical damage, extreme temperatures, or exposure to certain chemicals.
The last issue that is commonly encountered is related to its compatibility with other materials. As PVA water-soluble film is a synthetic material, it can tend to react with other materials, such as plastics or metals. This can result in the film becoming brittle or deteriorating.
Troubleshooting Solutions
Fortunately, many troubleshooting solutions are available to help you get the most out of your PVA water-soluble film. The first is to ensure the movie is stored in a cool, dry place, away from direct sunlight and extreme temperatures. This will help to keep the material in its most soluble form.
The second is to inspect the film for signs of wear and tear regularly. If it is found to be damaged, it is best to replace it with a new roll as soon as possible to prevent further damage.
Finally, if the film is being used with other materials, it is essential to ensure they are compatible. Ideally, use materials with a similar reactivity, such as polyethylene or polypropylene.
By following these steps, you can ensure that you get the most out of your PVA water-soluble film. Not only will it be more efficient, but it will also last longer, helping to reduce your costs in the long run.
