Polymer packaging film developed successfully

A university's School of Materials Engineering has successfully developed a polymer packaging film. The appearance is not different from common common plastic packaging film. However, when a piece of tear is put into a glass of cold water, the film will shrink rapidly in water, and it will be traced after 50s. no.

According to reports, this highly water-soluble packaging film is very suitable for quantitative packages that require toxic substances that can be used after being dissolved in water. For example, solid pesticides can be used to scientifically, conveniently, accurately formulate solutions with certain concentrations, and avoid direct contact with pesticides. Such as the use of such film packaging pouch detergent, do not use open, with the packaging directly into the washing machine will quickly dissolve, does not affect the quality of laundry, and non-toxic.
