FAQs

1. Avoid direct contact between the contaminated content inside the bag and the operator until the washing and drying cycle is completed, minimizing cross-infection and germs spread.
2. Avoid contaminated medical waste to be generated as the disposal bags completely dissolve in water, eliminating the traditional treatment by incineration or burying and reducing the treatment cost.
3. Greatly improve the hygiene of working environment, reduce working intension and enhance the labor protection.

Prosol is a kind of compound with modified high polymer (M-PVAL) and bio-based materials and can fully biodegrade in the natural environment. As a multi-functional fully biodegradable material, Prosol has been widely used in the fields and products of optics, engineering, agriculture and household.

Protect in need and disappear after use.
1. Resist to cold water and dissolve in hot water.
2. To be soft and disintegrated by stirring at cold water.
3. Fully biodegradable.

Water soluble film is made of polymer, polyvinyl alcohol. Like all polymer/plastic, it has its Tg. A glass transition temperature (Tg) is the temperature at which a polymer turns from a ductile material to a hard, brittle material. Each polymer with an amorphous structure has its own unique glass transition temperature, which makes a given polymer better suited for some applications over others. The PVA Tg is about 7-10 degree Celsius (44-50 degree Fahrenheit).. So during the cold season in the U.S., the temperature of storage and using should be much lower than such Tg.
