German scientists use medical expertise to create antibacterial packaging that can be applied to liquid beverages such as milk. This is an important change in food packaging technology. The food packaging department has always shown a strong interest in antibacterial coating films because it can prevent food molds from occurring without the use of food preservatives. Bacteria place themselves on food and packaging contact points and multiply quickly. In order to prevent the arrival of this uninvited guest, film-packed foods often have added preservatives such as sorbic acid and benzoic acid.

But wise consumers want fewer additives in food products as possible, which is the direct reason why food manufacturers have a surge in interest in antimicrobial packaging. They hope to make food more satisfying consumers' demand for fewer additives. Safety.

Researchers at the German processing plant and packaging Fraunhofer Association discovered that they would need to coat the packaging film in order to replace the preservatives in the food. The cladding can be realized by a material based on a composite resin or the like and a special technique. Such a plastic contains components such as glass and organic polymers.
