Water-soluble packaging bag, water-soluble is a pesticide, containing a variety of chemical properties: acid, alkali, corrosion, etc., so the packaging of water-soluble packaging bags can not be packed with a single layer of plastic film, to use multiple layers of different properties of plastic film composite into high-performance packaging bags.
The characteristics of water-soluble packaging bags are as follows：
1, safe and non-toxic: water-soluble film is safe and non-toxic to people, no stimulation, easy to degrade. After dissolved in water, the final degradation products are carbon dioxide and water, which can be excreted by metabolism after absorption by the human body.
2, environmental protection and easy to dissolve: The water-soluble film is a colorless transparent or colored opaque (transmittance adjustable) soft film (hardness adjustable), which can be quickly dissolved in water (under the condition of 5℃-30℃) within 2 minutes completely dissolved, above 30℃ conditions within 50 seconds all dissolved, so that the contents of the film can be quickly released, so that the effective ingredients quickly play a role. The film is neutral after dissolution, and the composition has no pollution to the environment. It is an environmentally friendly product.
3, oil resistance and corrosion resistance: water-soluble film is not dissolved in most organic solvents (such as benzene, xylene, etc.) and all animal oils, vegetable oils and petroleum hydrocarbons, but dissolved in glycerol, ethylene glycol, amide, triethanolamine and ethanolamine salt and dimethyl maple;
4, prevent static electricity: water-soluble film is a kind of anti-static film, different from other plastic films, has good anti-static property. In the process of using water-soluble film packaging products, it will not reduce its plasticity and electrostatic dust performance because of static electricity;
5, elastic tensile: water-soluble film thickness 0.03-0.05mm, its tensile strength is 100-300 kg/cm2, elongation is 10-600%, hardness is less than 10 Shore hardness. Because the film has good flexibility, can be made into various sizes of packaging forms, free packaging, easy to make bags, simple processing;
6, accurate measurement: water-soluble film unique elastic modulus and tensile strength, it has a high mechanical automatic packaging performance, suitable for a variety of automatic filling machines, improve the accuracy of the dose;
7, strong heat sealing: water-soluble packaging bag has good heat sealing, heat resistance temperature up to 140℃, suitable for resistance heat sealing and high frequency heat sealing;
8, breathable oxygen resistance: water-soluble film has strong permeability to water and ammonia, but has good barrier property to oxygen, nitrogen, hydrogen and carbon dioxide gas. These characteristics make it possible to maintain the ingredients and original odor of the packaged products, protect the activity of the contents well, and improve the effective utilization rate of pesticides;
9, clear printing: water-soluble film through the ink can be printed on the film surface of a variety of required color patterns, good printability.
