Patent

CA 2644761

A shrink-film seal (101, 201, 301, 401) is described having at least one stamped portion (102, 402, 602, 702) which is arranged along the circumference of a container (203, 303) which is to be sealed. The regions which are defined by the stamping lines are designed in such a way that at least one contiguous window is produced by a shrinking process. This achieves a situation where the opening of the sealed container can be immediately detected simply, without aids or expert knowledge and therefore a considerable increase in the product security is ensured. A method is also described for sealing containers with a shrink-film seal (101, 201, 301, 401).

L'invention concerne un scellé (101, 201, 301, 401) par film rétractable comprenant au moins un poinçonnage (102, 402, 602, 702) disposé le long du pourtour d'un récipient (203, 303) à sceller. Les zones définies par les lignes de poinçonnage sont configurées de telle sorte qu'au moins une fenêtre communicante est produite par un processus de rétreint. Grâce à cela, l'ouverture du récipient scellé est simple et identifiable immédiatement sans accessoires ni connaissances particulières, ce qui garantit une augmentation significative de la sécurité du produit. L'invention concerne également un procédé de scellement de récipients avec un scellé par film (101, 201, 301, 401) rétractable.
