Abstract: An integrated process for making an inflatable laminated article comprises extruding a first film and a second film, followed by cooling the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern. The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.

Abstract: An inflatable laminated article is prepared by contacting a first film with a second film, and heating selected portions of at least one the first and second films to a temperature above a fusion temperature of the first and second films, so that the first and second films are heat sealed to one another. The heat sealing is carried out in a pattern which provides a plurality of inflatable chambers between the first film and the second film. The first and second films are forwarded at a speed of at least 120 feet per minute while coming into contact with one another. The heating is carried out by contacting the first film with a heated raised surface roller having a release coating thereon.

Abstract: An inflatable laminated article is prepared by contacting a first film (8) with a second film (10), and heating selected portions of at least one the first and second films to a temperature above a fusion temperature of the first and second films, so that the first and second films are heat sealed to one another. The heat sealing is carried out in a pattern which provides a plurality of inflatable chambers between the first film and the second film. The first and second films are for warded at a speed of at least “0.6096 m/s” (120 feet per minute) while coming into contact with one another. The heating is carried out by contacting the first film with a heated raised surface roller (16) having a release coating thereon.

Abstract: An inflatable cushioning article is made from a multilayer film having a seal layer, a gas barrier layer, and a tie layer adhering the seal layer to the gas barrier layer. The cushioning article has a plurality of inflatable chambers, with each of the chambers having a plurality of cells connected in series to one another via inflation channels. Although the inflatable article can be made from relatively thin films, the article exhibits a relatively high burst pressure and can be inflated to, for example 3 psi, and withstand conditions such as 140° F. and high altitude, without film delamination, seal failure, or film rupture. Preferably, the tie layer comprises an anhydride modified polyolefin having an anhydride content of at least 150 ppm.
