Title
(EN) A PACKAGING LAMINATE AND PACKAGING CONTAINER PRODUCED THEREFROM
(FR) STRATIFIE POUR CONDITIONNEMENTS ET CONDITIONNEMENT PRODUIT AVEC CE STRATIFIE
Abstract
(EN)
A packaging laminate (10) comprising a core layer (11) and a gas barrier layer (14) of moisture- and liquid-sensitive barrier polymer, e.g. a copolymer of ethylene and vinyl alcohol (EVOH). The packaging laminate (10) preferably has outer liquid- tight coatings (12 and 13) of thermoplastic in order to make for sealing of the packaging laminate by thermosealing. In order to impart increased moisture and liquid protection to the moisture- and liquid-sensitive barrier layer (14), the packaging laminate (10) has a layer (16) of mineral filled polyolefin between the barrier layer (14) and the outer, liquid-tight coating (13) on the one side of the core layer (11). A packaging container produced from the packaging laminate (10) makes for the storage of a packed liquid food, such as juice, wine, cooking oil etc., with so-called extended shelf life.
(FR)
Ce stratifié pour conditionnements (10) est pourvu d'une couche noyau (11) et d'une couche barrière contre les gaz (14) constituée d'un polymère sensible à l'humidité ainsi qu'aux liquides, par exemple, d'un copolymère d'éthylène alcool vinylique (EVOH). Ce stratifié (10) est pourvu, de préférence, de revêtements extérieurs imperméables aux liquides (12 et 13), faits d'un matériau thermoplastique afin d'assurer une étanchéité dudit stratifié par thermoscellage. Afin de conférer une meilleure protection contre l'humidité et les liquides à cette couche barrière (14), le stratifié pour conditionnements (10) est pourvu d'une couche (16) de polyoléfine garnie de matière minérale, entre la couche barrière (14) et le revêtement extérieur imperméable aux liquides (13) et ce, sur l'un des côtés de la couche noyau (11). L'invention a également trait à un conditionnement obtenu à l'aide de ce stratifié (10), conçu pour le stockage de denrées alimentaires liquides telles que des jus, du vin, de l'huile à friture, etc., à durée de vie utile prolongée.
