Water-soluble powder packaging bags are generally used for the internal packaging of industrial products. They are soluble in water (the temperature of dissolved water is optional). They can be completely dissolved in normal temperature tap water (15 ℃ - 30 ℃) for 30 seconds. If the water volume increases or the water has fluidity, it will be faster. It will be completely dissolved in two minutes. Medium temperature and high temperature film can also be rapidly dissolved in aqueous liquid when reaching the design water temperature. This is another major technical breakthrough after our factory solved the technical problem of embroidery water-soluble film. It is different from the general packaging film. It has the characteristics of environmental protection, easy to dissolve, safe and non-toxic, oil and corrosion resistance, static electricity prevention, elastic tension, random packaging, accurate measurement, strong heat sealing, air permeability and oxygen resistance, clear printing, high anti-counterfeiting, and has passed the SGS certification monitoring. It can be packaged in powder, granular, oily semi-liquid, etc., and can be printed in single or double colors at present.
Precautions for use:
1. The dissolution rate is related to the 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. The larger the water volume, the faster the dissolution rate. The faster the water flow, the faster the dissolution rate;
2. The film is resistant to mineral oil, almost all oils and organic solvents, but it cannot contact the water-soluble film with strong acids, strong bases, chlorine free radicals and other substances that can react with the film (such as borax, boric acid, some dyes, etc.);
3. When not in use, it shall be sealed and packed to prevent moisture absorption and wrinkling.
Fujinfang Co., Ltd. has a large inventory of semi-finished products of various specifications for a long time. It can be cut according to the customer's packaging bag process needs and then made into finished bags of different sizes. If you need to order, please contact our business representative,
