The main raw material of PVA water-soluble film is polyvinyl alcohol. As a new concept of environmentally friendly packaging materials, PVA water-soluble film is widely used as inner packaging materials for water-soluble chemical products in Europe, America, Japan and other countries. For example: pesticides, chemical fertilizers, dyes, cleaning agents, water treatment agents, mineral additives, detergents, concrete additives, chemical reagents for photography and chemical reagents for garden care, etc., can also be used as rapeseed, plant seed bags, clothing packaging bags , food and hospital washing bags and other products inside and outside packaging.
PVA water soluble film has the following advantages:
1. The water-soluble film material is a new type of environmentally friendly material, which can be rapidly degraded and dissolved in water. The dissolved products are water and CO2, and no harmful substances are produced.
2. Simple and convenient to use, avoiding direct contact of users with harmful substances; oil-resistant, corrosion-resistant, and anti-static.
3. Good strength, toughness, plasticity, strong tensile resistance, good adhesion, and good heat sealing performance.

Normal temperature water-soluble film is also called fast-dissolving film and cold-dissolving film
Dissolving temperature: 15-30°C
Dissolving time: about 30 seconds
Complete dissolution time: 2 minutes
Application scenarios: Used for clothing embroidery substrates, agricultural seed bags, herbicide packaging bags, cleaning supplies packaging, chemical product packaging; washing and other disposable packaging bags. Does not damage clothes, does not affect washing effect, such as laundry beads, clothing embroidery backing.

Medium temperature water soluble film is also known as medium soluble film and hot soluble film
Dissolving temperature: 35-75 °C
Dissolving time: about 20 seconds
Complete dissolution time: 2 minutes
Application scenarios: washing bags for bedding, patient clothes, medical uniforms, window curtains, etc., sensitive fabric washing bags, hotel supplies packaging bags, and special bags for hotel fabric washing.

High-temperature water-soluble film is also called insoluble film, solvent-resistant film
Dissolving temperature: around 80-100 °C
Dissolving time: about 30 seconds
Complete dissolution time: W3 minutes
Application scenarios: used for advanced textiles, plastic outer packaging bags, packaging cushioning air cushions, book/paper protective films.

"Application Fields" dye packaging, seed packaging, agricultural medicine packaging, food packaging, chemical packaging, anti-sensitivity packaging, textile packaging, anti-static packaging, cement additive packaging.

"Precautions for use"
1. The dissolution rate depends on factors such as film thickness, water temperature, water volume and fluidity. Generally speaking, the thicker the film, the slower the dissolution rate, the higher the water temperature, the faster the dissolution rate, and the larger the water volume, the faster the dissolution rate. The faster it dissolves, the faster it dissolves;
2. When not in use, pack it in a sealed package to prevent moisture absorption and wrinkling;
3. The film is resistant to mineral oil, almost all greases and organic solvents, but it cannot be in contact with water-soluble films for strong acids, strong alkalis and other substances that can chemically react with the film (such as borax, boric acid, certain dyes, etc.) .
