Application Of PVA Water Soluble Membrane—Section 1
Packaging film
1.Agrochemical film
1.1Chemicals used in agriculture are usually highly toxic, which will cause serious pollution and endanger our health. Therefore, people pay more and more attention to the packaging materials of agricultural products. Although conventional agricultural packaging chemicals have been used for a long time, there are three main disadvantages. First of all, liquid agricultural chemicals are fragile when packed in glass bottles, leading to the leakage of toxic chemicals. Secondly, a large number of packaging residues will produce a large number of chemical wastes. Third, if the residual pesticide packaging is discarded in rivers, streams, farms or land, it will pollute the soil and water, and will harm the environment in the long run. The active agrochemical ingredients embedded in PVA water soluble membrane inhibit the skin and eyes of farmers/users from contacting harmful chemicals, and ensure that plants obtain appropriate agrochemicals to prevent disease and growth.

2.Cement/dye/enzyme membrane
The properties of cement additives/dyes/enzymes are alkaline, acidic and neutral. If the cement admixture commonly used outdoors is not controlled, it is easy to cause damage to the operator’s eyes and skin. Operators protect themselves by using various protective clothing and accessories to avoid personal injury. In recent years, PVA water-soluble films are increasingly used in the packaging of dyes, cement additives and enzymes to minimize pollution and provide consistent dosage in the manufacturing process of products. By using PVA water-soluble membrane, the mixing operation becomes simple and the measurement of additives is more accurate.

3.Liquid detergent
This application depends on the principle of using PVA water-soluble film packaging to provide a unit dose of liquid detergent products. Active concentrates of liquid detergent ingredients are packaged in PVA film. The formulation of PVA water-soluble film makes it compatible with liquid detergent for packaging, transportation, storage and use.

4.Bait film
PVA water soluble film bags are used to encapsulate the entire terminal block with dry feed such as pellets and pellets. High quality PVA water-soluble film bags are very popular because they combine strength, high melting rate and the ability to “lick and stick” corners, making the finished package more aerodynamic when casting. The bait and hook for deep-water fishing are packed in PVA water-soluble film bags to avoid the interference of fish in shallow water, so as to attract larger fish in deep-water fishing.

5.Seed belt
It is also possible to use hydrophilic water-soluble films or their composites to wrap the seeds equidistant in the form of strips, sheets or matrices to transport the seeds to the soil. This seed providing product can prevent seeds from going astray or minimize the waste of seeds located in cool or non germinating areas. This helps to optimize the use of the total area of soil/and seed.
Compared with other existing seed delivery systems, the water soluble film used for embedding or wrapping seeds can improve the germination speed. PVA water-soluble film seed packaging can ensure accurate seeding with less effort and less seed waste. Normal watering will dissolve the water-soluble film and ensure uniform depth and line. The seeds planted in this way can prevent the seeds from being blown away by the wind and eaten by animals, and keep the moisture in the soil intact. This method can also be used in conjunction with commercially available moisture absorbing materials to ensure that the germination rate of each farm seed is increased in dry or low rainfall seasons.

6.Laundry bag
PVA water-soluble membrane laundry bags are used in hospitals to minimize the contact of hospital staff with contaminated clothes and bedding. Dirt is put into these special bags and then directly into the washing machine. As the film is soluble in water, the bag will dissolve and wash into the sewer with dirty water. After the washing cycle, remove the clean clothes from the washing machine.

7.Toilet seat
The cast water-soluble film can be used to package all toilet blocks, helping to safely store toilet cleaner in hospitals, hotels and personal homes, thus ensuring that all toilets remain sterile and smell clean. Our products embed customized neutral or aromatic drugs in the film. According to laboratory research, the drugs embedded in the film can effectively fight against bacteria, bacteria, viruses and fungi, which makes PVA water-soluble film absolutely essential in the health industry.

8.Powder detergent
PVA water-soluble film used for powder detergent bags usually contains powder ingredients that are effectively soluble in water. Some products on the market contain concentrated powdered detergent in one compartment and degreaser in the other compartment, providing consumers with a product that can complete the work of multiple products and has the convenience of single unit dose packaging. PVA film is manufactured to the highest quality standards, which helps avoid pinholes when packaging powdered detergents.
