A method and apparatus of packaging food that involves severing plastic film by contacting it with a blade (110) at a temperature sufficient to cause plastic vaporization. The film is then secured to the tray to form the package. A mounting system for the blade permits the blade to expand as it heats up and to contract as it cools down.
La présente invention concerne un procédé d'emballage de produits alimentaires ainsi que l'appareil correspondant. Ce procédé consiste à couper un film plastique en le mettant en contact avec une lame (110) à une température suffisamment élevée pour provoquer la vaporisation du plastique. Le film est ensuite fixé au plateau pour constituer l'emballage. Un système de montage conçu pour la lame permet à celle-ci de se dilater lorsqu'elle chauffe et de se contracter lorsqu'elle refroidit.
