We specialize in the production of PVA water-soluble film water-soluble bags and their products.

Characteristics of water-soluble packaging bags

 The characteristics of water-soluble packaging bags are as follows:;
1. Safe and non-toxic: water-soluble film is safe, non-toxic, non irritating, and easily degradable to humans. After being dissolved in water, the final degradation products are carbon dioxide and water, which can be absorbed by the human body and excreted from the body through metabolism;
2. Environmentally friendly and soluble: The water-soluble film is a colorless transparent or colored opaque (with adjustable transparency) soft film (with adjustable hardness), which can quickly dissolve in water (under conditions of 5 ℃ -30 ℃) within 2 minutes and completely dissolve in 50 seconds under conditions above 30 ℃. Therefore, it can quickly release the contents of the film packaging, allowing the effective ingredients to quickly function. After the film dissolves, it becomes neutral and the ingredients do not pollute the environment, It is an environmentally friendly product;
3. Oil and corrosion resistance: The water-soluble film is insoluble in most organic solvents (such as benzene, xylene, etc.) and all animal oils, vegetable oils, and petroleum hydrocarbons, but soluble in glycerol, ethylene glycol, amide, triethanolamine, ethanolamine salt, and dimethyl maple;
4. Anti static: Water soluble film is an anti-static film that, unlike other plastic films, has good anti-static properties. During the use of water-soluble film packaging products, there will be no reduction in their plasticity or electrostatic dust retention performance due to static electricity;
5. Elastic tensile strength: The thickness of the water-soluble film is 0.03-0.05mm, with a tensile strength of 100-300 kilograms/square centimeter, an elongation of 10-600%, and a hardness of less than 10 Shore hardness. Due to its excellent flexibility, this film can be made into various sizes of packaging forms, which can be easily packaged and processed;
6. Accurate measurement: The water-soluble film has high mechanical and automatic packaging performance due to its unique elastic modulus and tensile strength, making it suitable for various fully automatic filling machines to improve the accuracy of dosage;
7. Strong heat sealing performance: water-soluble packaging bags have good heat sealing performance, with a maximum heat resistance temperature of 140 ℃, suitable for resistance heat sealing and high-frequency heat sealing;
8. Breathable and oxygen resistant: Water soluble membranes have strong permeability to water and ammonia, but have good barrier properties to oxygen, nitrogen, hydrogen, and carbon dioxide gases. These characteristics enable it to maintain the ingredients and original odor of the packaged product intact, effectively protect the activity of the content, and improve the effective use rate of pesticides;
9. Clear printing: Water soluble film can print various required color patterns on the surface of the film through ink, with good printability.
