Title (EN) SYSTEM AND METHOD FOR HEAT SEALING FOOD PACKAGING
(FR) SYSTÈME ET PROCÉDÉ DE THERMOSCELLAGE D'EMBALLAGE ALIMENTAIRE
Abstract:
(EN) The present disclosure is directed to systems and methods for heat sealing plastic packaging. In various embodiments, the disclosure provides a sealing system including a heater block with one or more coupling mechanisms for removable attachment to a silicone shoe. The silicone shoe includes a metal plate coated with or otherwise attached to a mineral-loaded silicone layer, which provides thermal conductivity. The sealing system can be attached to a conventional sealing assembly such that the silicone layer faces a direction toward lids over plastic packages. The silicone layer has a sealing surface which provides heat and pressure to the lids over the plastic packages thereby sealing the lids to the plastic packages. Due to the coupling mechanism, a degraded silicone shoe can be easily detached and replaced with a new silicone shoe.
(FR) La présente invention concerne des systèmes et des procédés de thermoscellage d'emballage plastique. Dans divers modes de réalisation, l'invention concerne un système de scellage comprenant un bloc chauffant pourvu d'un ou de plusieurs mécanismes d'accouplement pour une fixation amovible à un sabot en silicone. Le sabot en silicone comprend une plaque métallique revêtue par ou fixée d'une autre manière à une couche de silicone chargée de minéraux, qui fournit une conductivité thermique. Le système de scellage peut être fixé à un ensemble de scellage classique, de telle sorte que la couche de silicone fait face à une direction vers des couvercles sur des emballages en plastique. La couche de silicone présente une surface de scellage qui fournit de la chaleur et de la pression aux couvercles sur les emballages en plastique, scellant ainsi les couvercles aux emballages en plastique. Grâce au mécanisme d'accouplement, un sabot en silicone dégradé peut être facilement détaché et remplacé par un nouveau sabot en silicone.
