   Water Soluble Packing Film

Descriptions of the packing film:
1. Appearance: Colorless and transparent soft thin film.

2.Strength and toughness: Tensile strength:100-300kg/sqcm; Elongation rate:10-600%; Hardness: HBS <10

3. Solubility: The film can dissolved into water quickly and the solubility is weight ratio 1:1 of water to film.

4. Dissolution time: The dissolution of film starts immediately within 1 second and it fully dissolve into water within 1minute at the temperature of from minus 4℃ to 35℃ and above 35℃,it will fully dissolve into water less then 30 seconds.

5. PH value: 6-7

6. Toxicity: No absorption to human body and no stimulation to skin.

7. Biodegradability: It is degradable and the final products are carbon dioxide and water.

8. Air tightness: It is airtight for all the gases except water steam and ammonia. Oxidation resistance: It is stable in dry air for 3 years.

9. Moisture absorption: Moisture absorption happens at the humidity of >90% and no stick happen after drying for long time stay at the atmosphere of >90% humidity. Therefore, atmosphere with humidity of <60% is suggested for storage.

10. Dissolution in organic solvents: It can not dissolve into most of organic solvents except glycerine, ethylene glycol, amides, diethanolamine and triethanolamine salts and DMSO.

11. Optical and electrical properties and thermal stability: It is transparent to the visible light and has 77-82%transparency to UV but bi transparency to infrared light. It has a higher dielectric constant than the normal insulators(Relative humidity of 50% and frequency of 60HZ).It shows high thermal stability and is stable at the temperature of less than 140℃.
