High water-soluble packaging film, thin, light, smooth and transparent, looks no different from ordinary plastic film. However, when the reporter tears down a small piece and puts it into a normal cold water, it quickly shrinks and disappears after 50 seconds. This is a magical scene that the reporter saw yesterday in the laboratory of Prof. Wen Rujiang of the School of Materials Engineering of Suzhou University. Prof. Wen said that this highly water-soluble packaging film is non-toxic and biodegradable, and can be freely set to a degradation temperature within the range of 5°C to 80°C during production, and ensure that it is water-soluble in the set degradation temperature. A very practical and environmentally friendly material. At present, this technology holds a leading position in China.
In Professor Wen's laboratory, we saw a small bag of small detergents packed with this material. Professor Wen said that such washing powder can be put into the washing machine without disassembling the packaging bag. During the washing process, the packaging film is naturally dissolved and used very conveniently without affecting the quality of use. The highly water-soluble film is non-toxic and suitable for various food packaging, but it is particularly suitable for the packaging of solid toxic substances that require water-soluble use, such as the packaging of solid pesticides, which not only prevents the human body from direct contact with toxic substances, but also scientifically and accurately. Configure the desired concentration.
