Title (EN) HOT WELDABLE MULTILAYER PLASTIC FILM
(FR) FEUILLE MULTICOUCHE EN MATIERE PLASTIQUE SOUDABLE A CHAUD
Abstract:
(EN) A multilayer film for making containers to be provided with a cover by welding. The upper layer (7) is made up of a heterogenous mixture of two materials which have different coefficients of viscosity, the least viscous of the two being compatible with the bottom layer of the cover. The removal of the cover causes the upper layer (7) to tear by means of a loss of cohesion.
(FR) Feuille multicouche pour constituer des récipients à operculer par soudage. La couche supérieure (7) est constituée d'un mélange hétérogène de deux produits ayant des coefficients de viscosité différents, le plus fluide étant compatible avec la couche inférieure (8) de l'opercule. L'enlèvement de l'opercule entraîne un déchirement de la couche supérieure (7) par décohésion.
