INTEGRATED PROCESS FOR MAKING INFLATABLE ARTICLE

摘要

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 anothe r upon contact with each other. The films are then brought into contact with o ne 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.
