Water soluble packaging bag features
2019-03-09 16:49:41

The characteristics of the water-soluble packaging bag are as follows;
1, safe and non-toxic: water-soluble membrane is safe, non-toxic, and easy to degrade. After being dissolved in water, the final degradation products are carbon dioxide and water, which can be excreted by metabolism after being absorbed by the human body;
2, environmentally friendly and easy to dissolve: water-soluble film is colorless transparent or colored opaque (transparent adjustable) soft film (hardness adjustable), which can be quickly dissolved in water (at 5 ° C - 30 ° C) 2 minutes It is completely dissolved in the inside and dissolves completely in 50 seconds at 50 ° C or above. Therefore, the contents packaged in the film can be quickly released, so that the active ingredient can quickly function, the film is neutral after dissolution, and the composition is not polluted by the environment. Environmentally friendly products;
3, oil and corrosion resistance: water-soluble film is not soluble 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 sulfoxide;
4, to prevent static: water-soluble film is an anti-static film, unlike other plastic films, has a good anti-static properties. In the process of using a water-soluble film packaging product, it does not cause plasticity reduction and electrostatic dust-retaining performance due to static electricity;
5, elastic tensile: water-soluble film thickness 0.03-0.05mm, its tensile strength is 100-300 kg / cm 2, elongation is 10-600%, hardness is less than 10 Shore hardness. Since the film has good flexibility, it can be made into various sizes of packaging forms, which are easy to package, easy to make, and easy to process;
6. Accurate measurement: It has high mechanical automatic packaging performance when the water-soluble film has unique elastic modulus and tensile strength, and is suitable for various automatic filling machines to improve the accuracy of the dosage;
7. Strong heat sealing property: The water-soluble packaging bag has good heat sealing property, and the heat resistant temperature is up to 140 ° C, which is suitable for resistance heat sealing and high frequency heat sealing;
8. Breathable oxygen barrier: The water-soluble membrane has strong permeability to moisture and ammonia, but has good barrier properties against oxygen, nitrogen, hydrogen and carbon dioxide gas. These characteristics make it possible to maintain the composition and original odor of the packaged product intact, which can well protect the activity of the contents and improve the effective use rate of the pesticide;
9. Clear printing: The water-soluble film can print various color patterns on the surface of the film through the ink, and the printing property is good.
