Germany tries to use "stained" film to extend food preservation

Recently, a chlorophyll-stained plastic film was introduced to prevent rot from chlorophyll in light and green foods to cause food rot, thus greatly prolonging the preservation time of green foods.

The results were obtained by German scientists. Scientists used plastic films to “stain” them with special methods. After such processed films were used to package foods, they could effectively “intercept” the light that caused the food to decay. Extended food preservation period. The new method is not only easy and inexpensive.
