(EN) PACKAGING MATERIAL AND METHOD FOR MANUFACTURING THE SAME
(FR) MATERIAU D"EMBALLAGE ET SON PROCEDE DE FABRICATION
Abstract
(EN)
The present invention provides a cost-effective method for manufacturing packaging materials having oxygen and moisture barrier properties, comprising applying a coating of ethylene vinyl alcohol to the substrate film and wherein the coating of ethylene vinyl alcohol is applied using a solution with an ethylene content of between 4 and 18%mol.
(FR)
La présente invention porte sur un procédé de fabrication économique de matériaux d"emballage possédant des propriétés barrières à l"oxygène et à l"humidité. Ce procédé consiste à appliquer une revêtement à base d"éthylène alcool de vinyle sur un film substrat, ce revêtement étant appliqué au moyen d"une solution dont la teneur en éthylène est comprise entre 4 et 18 % en mole.
