A method for making continuous rolls of a thin laminate composite that is ideally suited for the large scale production of reclosable bags which can be used for sealably packaging a wide variety of articles, including food products. The bags of the invention, after being opened, can quickly and easily be closed by rolling the open end downwardly upon itself in a manner to sealably deform one or more inelastic, malleable metal filaments (16, 18) which are encapsulated within at least one of the laminate side walls (12, 14) of the bag. The novel laminate composite material produced by the method of the invention comprises first and second thin layers of film (48, 68) between which one or more lengths of thin malleable metal filaments (84) are sealably encapsulated.
Procédé de fabrication de rouleaux continus de composite laminé mince idéalement adapté à la production à grande échelle de sacs refermables pouvant servir à mettre sous emballage scellé une large variété d'articles, notamment alimentaires. Lesdits sacs après avoir été ouverts peuvent être refermés vite et facilement en en roulant l'extrémité ouverte vers le bas sur elle-même ce qui déforme en vue du scellement un ou plusieurs filaments métalliques inélastiques malléables (16, 18) emprisonnés dans l'une au moins des parois (12, 14) du sac. Le nouveau composite laminé mince est fait de deux films (48, 68) entre lesquels une ou plusieurs longueurs de filaments métalliques inélastiques malléables (16, 18) sont emprisonnées.
