What is PVOH water soluble film?
PVA or PVOH Water Soluble Film is a versatile plastic packaging material that offers numerous benefits compared to traditional plastic films. It is a biodegradable, non-toxic, and environmentally friendly product made from polyvinyl alcohol (PVOH) and sodium carboxymethyl cellulose (CMC) resins. This film is a perfect solution for companies looking to reduce their reliance on single-use plastic packaging.
The Overview of PVOH Water-Soluble Film
Water-soluble films are used for various packaging applications. From agriculture, construction to the medical industry, etc., water-soluble film packaging is becoming more and more popular environmentally friendly packaging
According to different applications and dissolution temperatures, there are different classifications of water-soluble films
According to different dissolution temperatures, water soluble films can be divided into cold water soluble films and hot water soluble films. Generally speaking, a water-soluble film dissolved at 5 ° C to room temperature is often defined as a cold water soluble film, and a water-soluble film dissolved above 70 ° C is defined as a hot water soluble film
According to different application areas and efficacy, water-soluble film can be divided into packaging film, water transfer film, embroidery film, artificial marble or quartz stone release film
The film used to make conventional packaging bags, such as supermarket shopping bags and electronic products packaging bags, uses a hot-water soluble film with a water soluble temperature of more than 70 degrees
The water-soluble films used as seed packaging, dye packaging and concrete additives are usually cold-water soluble films
The PVOH water soluble release films which are used for artificial marble or quartz stone is a high temperature water soluble film, can withstand high temperatures above 170 degrees.
And embroidery film – water soluble film, water transfer water soluble film is usually cold water soluble film
Enterprises can choose water-soluble films with different efficacy and water-soluble temperature according to the needs of their products, so as to achieve environmentally friendly packaging and maximize the utilization rate of products.
Benefits of Using Water-Soluble Film
Water soluble film offers numerous benefits for companies looking to reduce their reliance on single-use plastic packaging. Here are some of the main advantages of using water-soluble film for packaging:
Cost Savings:
Water soluble film is more cost-effective than traditional plastic packagin in some ways. It is water soluble and biodegradable , so it can be delt with easier than traditional plastic packaging and save the waste disposal cost
In addition, in some scenarios where there is no need to open the package, water-soluble packaging can reduce waste and improve the efficiency of product use. For example, water-soluble film or water-soluble bag can be used for pesticide packaging. When using pesticides, the soluble packaging bag and pesticide can be thrown into the container to stir. In this way, not only can avoid pesticide residue on the bag, reduce waste, but also avoid the residual pesticide pollution to the environment.
Eco-Friendly:
The soluble film is non-toxic, water soluble and fully biodegradable. This makes it a much better choice than traditional plastic packaging, which is not biodegradable and can take centuries to break down.
Versatility:
The soluble film is highly versatile and can be used for various applications, from food packaging to industrial parts. It can also be easily customized to meet specific needs and requirements.
Strength:
Water soluble film is a solid material resistant to tearing and punctures. This makes it an excellent choice for products that must be packaged securely.
Water soluble film is an excellent option for companies looking for a more sustainable and economical packaging solution. It is versatile, robust, and eco-friendly, making it a perfect choice for many applications. Additionally, it can be customized to meet specific needs and requirements, making it an ideal choice for companies that need to package their products securely and cost-effectively.
How to seal water soluble film?
There two ways to seal the water -soluble film . One is to seal with the suitable glue , another one is to heat seal with machine. Sealing water-soluble film can be tricky, but if done correctly, it can provide a lasting solution that ensures the film’s performance. In the next paragraphs, we will mainly look at the steps how to seal the water soluble films with the right sealant (or glue).
Preparation Before Applying Sealant
Before beginning the sealing process, preparing the film’s surface is essential. This includes cleaning the film to remove any dirt, dust, and other debris that may be present on the surface. It is also necessary to ensure the surface is arid before applying the sealant.
Choosing the Right Sealant
Once the surface has been prepared, it is essential to choose the proper sealant. The type of sealant used will depend on the kind of film being sealed and the application. Water-based adhesives are typically used for filling water-soluble movies and are generally easy to work with. Solvent-based sealants are also available and can be used for more specialized applications.
Applying the Sealant
Once the proper sealant has been chosen, it is time to apply it to the surface. It is essential to ensure that the adhesive is evenly spread and that there are no gaps or bubbles. It is also necessary to ensure that the bond is used according to the manufacturer’s instructions.
When applying the sealant, it is essential to start at the edges of the film and work your way in. This will ensure that the adhesive is evenly spread and that the edges of the film are appropriately sealed. Using a brush or roller is also essential to ensure that the bond is evenly distributed.
Final steps-keep the films properly
Preserving and protecting your water-soluble film is a necessary filmmaking process. Without taking the correct steps, the film may suffer from weathering, wear and tear, and other forms of damage.
Finally, it’s time to store the film properly after finishing all the above sealing steps. This means ensuring it’s being removed from direct sunlight, moisture, and other environmental factors that can cause damage. The best way to do this is to store the film in an airtight container, away from direct sunlight and other heat sources. This will ensure that the film is kept in the best condition possible for years to come.
Conclusion
Sealing water-soluble film can be tricky, but if done correctly, it can provide a lasting solution that ensures the film’s performance.
Following the steps outlined in this blog will help you preserve and protect your films in good condition for years.
