Title
(EN) PLASTIC FILM AND METHOD FOR MAKING PNEUMATICALLY FILLED PACKING CUSHIONS
(FR) FILM PLASTIQUE ET PROCEDE DE FABRICATION DE COUSSINS D'AMORTISSEMENT POUR L'EMBALLAGE REMPLIS D'AIR
Abstract
(EN)
Plastic film material (14) and method for the manufacture of pneumatically inflated packing cushions, wherein transverse rows of perforations (16, 17) are formed across two elongated, superposed layers of plastic film material, the layers are sealed together along lines (18) defining a plurality of cushions separated by the perforations, and the material is then formed and rolled for shipment and storage. At the time and place the cushions are to be used, the material is unwound from the roll and fed to a relatively simple machine where air or other suitable gas is injected between the two layers, and the material is sealed to complete the cushions. In some embodiments, the film material is in the form of a flattened tube, and in other it is the centerfold material in which the film is folded along its centerline.
(FR)
L'invention porte sur un film plastique (14) et sur un procédé de fabrication de coussins d'amortissement pour l'emballage remplis d'air. Des rangées de perforations (16, 17) sont formées dans deux couches superposées, allongées, de film plastique, ces couches étant soudées le long de lignes (18) formant une pluralité de coussins séparés par les perforations. Le matériau est ensuite formé et enroulé pour être expédié et stocké. Au moment et sur le lieu d'utilisation des coussins, le matériau est déroulé du cylindre et amené vers une machine relativement simple où de l'air ou un autre gaz approprié est injecté entre les deux couches, ce matériau étant ensuite soudé de façon à former les coussins. Selon certaines réalisations, le film se présente sous la forme d'un tube aplati, et selon d'autres, c'est un matériau dossé dans lequel le film est plié le long de sa ligne centrale.
