Title
(EN) PACKAGING MATERIAL HAVING IMPROVED BARRIER PROPERTIES
(FR) MATERIAU D'EMBALLAGE AYANT DES PROPRIETES BARRIERE AMELIOREES
Abstract
(EN) A composite material suitable for packaging moisture or oxygen sensitive products comprising one or more polymeric substrate(s) and one or more barrier property-providing coating(s), ink(s) and/or adhesive(s) on or between said substrate(s) being cured from composition(s) comprising alpha, beta ethylenically unsaturated monomer(s) and/or oligomer(s). A method for providing barrier properties to a polymeric substrate comprising applying a barrier property-providing amount of a composition comprising alpha, beta ethylenically unsaturated monomer(s) and/or oligomer(s) as a coating, ink or adhesive on the substrate or between two or more of said substrates; and curing the composition. Articles comprising perishable material or articles enclosed within a package comprised of such composite material.
(FR) Un matériau composite adapté pour emballer des produits sensibles à l'humidité ou à l'oxygène comprend un ou plusieurs substrats polymères et une ou plusieurs couches conférant des propriétés barrière, une ou des encres et/ou un ou plusieurs adhésifs situés sur ou bien entre lesdits substrats, les couches, les encres et/ou les adhésifs étant durcis à partir d'au moins une composition contenant un ou plusieurs monomères et/ou oligomères alpha, bêta non saturés par l'éthylène. On décrit un procédé permettant de conférer des propriétés barrière à un substrat polymère qui consiste à appliquer une quantité conférant des propriétés barrière à une composition contenant un ou plusieurs monomères et/ou oligomères alpha, bêta non saturés par l'éthylène, sous forme de couche, d'encre ou d'adhésif situé sur le substrat ou bien entre au moins deux substrats ; puis à durcir la composition. L'invention concerne également des articles comprenant des matières périssables ou des articles enfermés dans un emballage formé d'un tel matériau composite.
