Toxin Alor-tIne recently announced that it has invented a food preservative film that can detect food spoilage and toxic. According to reports, the plastic wrap film coated with a chemical substance will deform when it encounters certain toxins and changes from round to flat. The use of the plastic wrap can detect Salmonella, koji, Escherichia, and Listeria. The coated chemicals are non-toxic and do not contaminate the food. The company's new plastic wrap will soon be on the market. The cost of the new cling film is estimated to be 25% higher than the normal cling film.
