PVA water-soluble film casting equipment is a new type of casting film equipment developed by our company, which breaks through the original steel strip film making method. It uses super large drum and special molds with a powerful external heating system: PLC program control, high degree of automation, fast production line speed, and uniform thickness of the film

The environmental characteristics of PVA water-soluble film:

PVA (polyvinyl alcohol) water-soluble film, as a new type of green and environmentally friendly material, is widely used in embroidery, water transfer printing, "blue bubbles", agricultural films, chemical packaging, laundry packaging (anti infection packaging), textile packaging (clothing packaging), food packaging, electronic packaging, dyes and other fields. It has the following characteristics:

1. Environmental friendliness: It has both water and biological degradation characteristics

a. Firstly, it dissolves in water to form a gel solution that penetrates into the soil, increasing the soil's clumping, permeability, and water retention, making it particularly suitable for sandy soil transformation

The PAV material in the soil can be decomposed by bacterial strains isolated from the soil fill and ultimately degraded into CO2 and H2O, completely solving the pollution problem

2. Safety can avoid direct contact between users and toxic substances

3. Water solubility: Soluble in water. Temperature control can change the dissolution rate.

4. Transparency and glossiness: PVA film has better transparency and glossiness than other films

5. Moisture permeability: the moisture permeability of PVA film is similar to that of cellophane, which is a kind of moisture permeability and high film. When packaging hot and wet articles, no droplets will be generated

6. Barrier property: The use of PVA film can maintain the composition and odor of the packaged product in good condition

7. Anti static: The use of PVA film packaging products will not cause a decrease in their plasticity or electrostatic dust accumulation due to static electricity during the process

8. Printability: PVA film has strong polarity and good printing performance. Corona treatment is not required during printing, and it has been widely used in the special printing industry, such as water transfer film substrate

9. Good heat sealing performance, especially suitable for resistance heat sealing and high-frequency heat sealing; 10. Oil resistance and organic solvents: 11 Water and gas permeability

Product application of PVA water-soluble film:

1. Pesticide: The inner packaging lining bag of chemical products can avoid touching pesticides by hand and there are no residual pesticides in the chemical products in the plastic bag. 2. Cement additive (silicon powder) packaging bag can avoid dust flying and endangering the environment

3. Fabric carrier for embroidery wigs and other items: The backing carrier is easy to clean

4. Making marble demolding film: Water soluble film can be quickly demoulded on the inner lining of the mold

5. Curved surface printing (water transfer printing): Printing on this film can be transferred onto the curved surface,

6. Seed bags pack seeds at fixed intervals and bury them underground to save valuable seeds and avoid the hassle of thinning seedlings

7. Hospital washing packaging bags do not require contact with contaminated clothes. The entire bag can be put into the washing machine for washing. 8. Common seat side heat pads can be placed on the seat cushion to avoid bacterial infection

9. Hot water soluble film suitable for clothing packaging

10. After compounding with other plastics, it can be used for food preservation packaging and air cushion bags
