Patent

CA 2629394

An integrated process for making an inflatable laminated article comprises extruding (11) a first film and a second film, followed by cooling (14) 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 (15, 16). 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.
