operculeuse

OBS: opercule : Découpe en aluminium mince, film plastique ou complexe servant à la fermeture de petits contenants (pots de yaourt, petits suisses, etc.).

OBS: The use of inductive heat-sealing equipment instead of conductive heat sealing is broadening the applications for foil lidding. Inductive sealing does not heat the lid by direct contact. Heat is brought into the lidding stock by a magnetic field through which the container and lid pass. The magnetic field heats the foil in the lid and an effective, hermetic seal forms between the lid and the container.
