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.
Claims2
A method for packaging products, particularly food products, and for sterilizing them in an alternating high-frequency electromagnetic field, comprising the steps of:
- forming a traveling laminate having a metallic layer into a container to provide a trough-like area into which a product is to be introduced;
- advancing the formed container past a product discharge point to deposit a predetermined quantity of said product into said container;
- covering the container with a synthetic film introduced thereover from a traveling web;
- moving the containers seriatim through a high-frequency microwave field and
- applying a sealing layer of a metallic foil over the synthetic film.
