Definitions

  • This invention pertains generally to packing materials and, more particularly, to a processed plastic film material and method for the manufacture of pneumatically filled packing cushions.
  • Air-filled packing cushions are used to fill up empty spaces in packing containers and to provide protection for fragile goods. These cushions are usually manufactured by feeding an unprocessed length of plastic film material from a storage roll to a machine that processes it by sealing two layers of the material together along lines which define the cushions, injecting air between the layers to inflate the cushions, and perforating the material between the cushions. Such machines are complex and also require time-intensive maintenance.
  • Another object of the invention is to provide a roll of processed plastic film material and method of the above character from which pneumatically filled packing cushions can be manufactured with a simple machine.
  • a plastic film material and method for the manufacture of pneumatically inflated packing cushions wherein transverse rows of perforations are formed across two elongated, superposed layers of plastic film material, the layers are sealed together along lines defining a plurality of cushions separated by the perforations, and the material is then formed the film material into a roll for shipment and storage.
  • 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.
  • the film material is in the form of a flattened tube, and in others it is a centerfold material in which the film is folded along its centerline.
  • a marker is placed on the film for use in positioning the film in the machine which injects the air and seals the film to form the cushions.
  • Figure 1 is an isometric of one embodiment of a roll of processed plastic film material incorporating the invention for use in the manufacture of pneumatically filled packing cushions.
  • Figure 2 is a fragmentary top plan view of one embodiment of a processed plastic film material incorporating the invention for use in the manufacture of pneumatically filled packing cushions.
  • Figure 3 is a transverse sectional view of the embodiment of Figure 2.
  • Figure 4 is a fragmentary top plan view of another embodiment of a processed plastic film material incorporating the invention for use in the manufacture of pneumatically filled packing cushions.
  • Figure 5 is a transverse sectional view of the embodiment of Figure 4.
  • an elongated length of plastic film material 1 1 is wound about a central shaft or core 12 to form a roll 13 for use in the manufacture of pneumatically inflated packing cushions.
  • the shaft is shown as having a circular cross section, it can have any other suitable shape, such as a polygon.
  • the film material is fed from the roll to a machine that further processes it and fills it with air or other suitable gas to form the packing cushions.
  • the film material is in the form of a flattened tubular film 14 which is provided with transverse rows of perforations 16, 17 that are spaced at regular intervals along the length of the tubing. Each of the rows of perforations extends over the entire width of the tubular film.
  • the film is sealed together along lines 18 on opposite sides of every other one of the rows of perforations, i.e. next to rows 16. These seal lines are formed close to the perforations and extend across the entire width of the film to seal off the perforations in rows 16 from the rest of the material.
  • Markers 19 are provided near the intermediate rows of perforations 17, i.e. the rows which do not have the seal lines next to them. These markers can be detected optically, magnetically or by other suitable means, and can be utilized to indicate the position of the tubular film and the rows of perforations in the machine which makes the cushions.
  • the material is fed from a roll into a machine (not shown) which introduces air or other suitable gas into the tubing through perforations 17, then forms transverse seal lines similar to seal lines 18 next to the perforations to prevent the air from leaking out. Since the perforations are preformed, the machine does not have to make them, and the inflation and sealing can be done with a relatively simple, inexpensive machine.
  • the material can be prepared with seal lines 18 on both sides of all of the rows of perforations, in which case the air or other gas can be introduced into the cushions through a hollow needle punched through a wall of the film. After the air or gas has been injected, the needle is withdrawn, and the hole formed by the needle is closed by heat sealing.
  • the film material is a type sometimes referred to as a centerfold film 21 . It consists of an elongated sheet of film material which is folded along its centerline with one closed edge 22 and one open edge 23. As in the embodiment of Figure 2, transverse rows of perforations 24 are formed at regular intervals along the length of the material. Each of these rows extends across the entire width of the folded material.
  • the folded material is sealed together along lines 26 on either side of each of the rows of perforations. These seal lines are formed close to the perforations, and extend from the closed edge 22 of the material to within a short distance from the open edge 23.
  • markers similar to markers 19 in the embodiment of Figure 2 can be provided for use in aligning the film material in the machine which makes it into cushions.
  • the processed material is formed into rolls 13 for shipment and storage.
  • the material is fed from a roll into a machine (not shown) which introduces air or other suitable gas through the open edge 23 and between the two layers of the folded film.
  • the machine then seals the two layers together along a longitudinally extending line 28 which intersects the transverse seal lines

Abstract

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.
