Detailed Introduction:

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; the larger the water volume, the faster the dissolution rate; and the faster the water flow, the faster the dissolution rate;

2. When not in use, seal and package it to prevent moisture absorption and wrinkling;

3. This film has both front and back sides, with the front side being bright and the back side being dull. It is recommended to choose the best option when using it,.

4. The film is resistant to mineral oil, almost all oils and organic solvents, but cannot come into contact with water-soluble films for strong acids, strong bases, chlorine free radicals, and other substances that can react chemically with the film (such as borax, boric acid, certain dyes, etc.).
