Abstract:
(EN) A clear, flexible, sealed container (10) may be made of first and second plastic sheets (12, 14) sealed together at their peripheries (15). The first plastic sheet (12) defines a bulge (18) to increase the inside volume of the container, and comprises a laminate of a layer of polyolefin and a blended layer of polyolefin and a block copolymer of polyolefin and polystyrene. The second plastic sheet (14) is a bonded laminate of a layer of biaxially oriented polypropylene and nonoriented polypropylene, peripherally bonded to the layer of polyolefin of the first plastic sheet (12).
(FR) Un conteneur scelle, transparent, flexible (10) peut etre constitue par une premiere et une seconde feuilles de plastique (12, 14) scellees a leurs peripheries (15). La premiere feuille de plastique (12) definit un renflement (18) pour augmenter le volume interieur du conteneur, et comprend un lamine d'une couche de polyolefine et une couche composite de polyolefine et d'un copolymere en bloc de polyolefine et de polystyrene. La seconde feuille de plastique (14) est un lamine d'une couche de polypropylene a orientation biaxiale et de polypropylene non oriente, lie a la peripherie sur la couche de polyolefine de la premiere feuille de plastique (12).
