ABSTRACT:
A method is proposed for packaging products, particularly food products, and sterilizing them in an alternating high-frequency electromagnetic field. The product is first introduced into trough-like, preferably interconnected containers provided with a metallic layer; then the containers are closed with a synthetic film, brought within the range of an alternating high-frequency electromagnetic field, and finally sealed with a foil having a metallic lamina which covers the synthetic film.
