Water Soluble Film (WSF) 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 Water-Soluble Film

Water-soluble films are used for various packaging applications, from food products to industrial parts. WSF is a thin, flexible film made from PVOH and CMC components. Together, these two components create a plastic-like material that is water-soluble and biodegradable.

PVOH is a semi-crystalline polymer in many industries, including pharmaceuticals and medical devices. It is a solid and durable material, but it is also water-soluble. CMC is a cellulose derivative that is both non-toxic and biodegradable. It is widely used in many products, including food, paper, and cosmetics.

When the two components are combined, they create a unique material with many advantages. It is solid yet water-soluble. This means that it can be easily dissolved in water and does not require any additional processing. Additionally, it is non-toxic, biodegradable, and fully recyclable.

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:

1. Cost Savings:

WSF is more cost-effective than traditional plastic packaging. It is more lightweight, meaning it costs less to transport and requires less energy.

2. Eco-Friendly:

WSF is non-toxic, biodegradable, and fully recyclable. This makes it a much better choice than traditional plastic packaging, which is not biodegradable and can take centuries to break down.

3. Versatility:

WSF 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.

4. Strength:

WSF 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.

There two ways to seal the water -soluble film . One is to seal with the suitable glue , another one is to hot 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 this blog, we will 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.

Once the surface has been prepared, it is essential to create a smooth, even surface that will make it easier to seal the film.

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.

When choosing a sealant, it is essential to make sure that it is compatible with the film being sealed. It is also necessary to ensure that the bond is designed for the type of application. For example, some bonds are explicitly designed for outdoor use, while others are intended for indoor use.

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.
