LAMINATE STRUCTURE FOR SEALING CHANNEL LEAKERS

In the disclosed invention, a laminate film for a food package comprises a high melt polymer that flows, upon pressure and/or temperature from sealing jaws, into triangular areas created hy overlapping films. In one aspect, the high melt polymer comprises a melt index of between about 10 dg/min and...

More Information
Summary:In the disclosed invention, a laminate film for a food package comprises a high melt polymer that flows, upon pressure and/or temperature from sealing jaws, into triangular areas created hy overlapping films. In one aspect, the high melt polymer comprises a melt index of between about 10 dg/min and about 50 dg/min. In one aspect, the high melt polymer is disposed between two skin layers. The innovative laminate provides the advantage of a simple, economical method of sealing areas that have previously been recalcitrant. La présente invention concerne un film stratifié pour un emballage de produits alimentaires comportant un polymère à température de fusion élevée qui se fluidifie, sous une pression et/ou température dérivée de bords d'étanchéité, dans des zones triangulaires créées par les films se chevauchant. Dans un aspect, le polymère à température de fusion élevée présente un indice de fusion compris entre environ 10 degrés/minute et environ 50 degrés/minute. Dans un aspect le polymère à température de fusion élevée est disposé entre deux couches de peau. Le stratifié de l'invention procure l'avantage d'un procédé simple et économique pour l'étanchéification de zones qui se sont avérées résistantes précédemment.
