Bacteria are bred at the point of contact between food and packaging. To prevent the arrival of these uninvited guests, German scientists have recently used medical expertise to develop an antimicrobial plastic food packaging.

This kind of packaging uses coating technology to add a layer of antiseptic and antibacterial material on the plastic packaging film instead of the preservative added in the food. Such coating can be realized by using composite resin and other substances as base materials and special technologies. This is an important change in food packaging. It can prevent food mildew from occurring without the use of food preservatives.
