The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.

1. A method for manufacturing an inflatable article of footwear, comprising the steps of: (a) providing a first film;(b) applying a barrier material using a screen, template or stencil to a first side of said first film in a bladder configuration;(c) providing a second film with said first film, suc
1. A method for manufacturing an inflatable article of footwear, comprising the steps of: (a) providing a first film;(b) applying a barrier material using a screen, template or stencil to a first side of said first film in a bladder configuration;(c) providing a second film with said first film, such that said barrier material is disposed between said first film and said second film;(d) adhering said first film to said second film to form a sealed peripheral area, except in the area where said barrier material has been applied to said first film, to form at least one inflatable compartment corresponding in overall shape to said bladder configuration;(e) coupling an inflation device and a deflation device to said inflatable compartment, wherein said inflation device and said deflation device is a fitment coupled to said inflatable compartment at an opening through at least one of said first film or said second film and along a conduit formed between said first and second films;(f) cutting along said sealed peripheral area to form a bladder having said at least one inflatable compartment and a sealed peripheral edge; and(g) incorporating said bladder into footwear to form the inflatable article of footwear, wherein said inflation device and said deflation device permit selective, repeated inflation and deflation of said bladder. 2. The method of claim 1, wherein said barrier material is a paint, ink, photosensitive material, particulate or acid. 3. The method of claim 1, wherein said barrier material is a photosensitive material. 4. The method of claim 3 further comprising the step of exposing the photosensitive material to light. 5. The method of claim 1, wherein the barrier material is applied using screen printing. 6. The method of claim 1, wherein said first and second films are thermoplastic layers. 7. The method of claim 6, wherein said one of said first or second film is a laminate comprised of a thermoplastic layer and a substrate. 8. The method of claim 1, wherein said inflation device is a pump and said deflation device is a release valve. 9. The method of claim 1, wherein said step of adhering said first film to said second film is accomplished by calendaring said first and second films through first and second rollers. 10. The method of claim 1, wherein said step of adhering said first film to said second film is accomplished by applying a heated platen to a side of either said first film or said second film. 11. A method for manufacturing an inflatable bladder, comprising the steps of: (a) providing a first film having a first side and a second side;(b) applying a photosensitive barrier material to said first side of said first film;(c) providing a second film and positioning said second film over said first side of said first film, such that said barrier material is disposed between said first film and said second film;(d) adhering said first film to said second film to form a sealed peripheral area, except in the area where said barrier material has been applied to said first side of said first film, to form at least one inflatable compartment corresponding in overall shape to a bladder configuration;(e)coupling an inflation device and a deflation device to said inflatable compartment, wherein said inflation device and said deflation device is a fitment coupled to said inflatable compartment at an opening through at least one of said first film or said second film and along a conduit formed between said first and second films; and(f) cutting along said sealed peripheral area to form a bladder having said at least one inflatable compartment and a sealed peripheral edge, wherein said inflation device and said deflation device permit selective, repeated inflation and deflation of said bladder. 12. The method of claim 11 further comprising the step of exposing the photosensitive barrier material to light. 13. The method of claim 11, wherein the photosensitive barrier material is applied using a screen, template or stencil. 14. The method of claim 11, wherein the photosensitive barrier material is applied using screen printing. 15. The method of claim 11, wherein said first and second films are thermoplastic layers. 16. The method of claim 15, wherein said one of said first or second film is a laminate comprised of a thermoplastic layer and a substrate. 17. The method of claim 11, wherein said first film is sealed to said second film by application of a heated platen. 18. A method for manufacturing an inflatable article of footwear, comprising the steps of: (a) providing a first film;(b) applying a photosensitive barrier material using a screen, template or stencil to a first side of said first film in a bladder configuration;(c) exposing the photosensitive barrier material to light;(d) providing a second film and positioning said second film over said first film, such that said photosensitive barrier material is disposed between said first film and said second film;(e) adhering said first film to said second film to form a sealed peripheral area, except in the area where said photosensitive barrier material has been applied to said first film, to form at least one inflatable compartment corresponding in overall shape to said bladder configuration;(f) coupling an inflation device and a deflation device to said inflatable compartment, wherein said inflation device and said deflation device is a fitment coupled to said inflatable compartment at an opening through at least one of said first film or said second film and along a conduit formed between said first and second films;(g) cutting along said sealed peripheral area to form a bladder having said at least one inflatable compartment and a sealed peripheral edge; and(h) incorporating said bladder into footwear to form the inflatable article of footwear, wherein said inflation device and said deflation device permit selective, repeated inflation and deflation of said bladder. 19. The method of claim 18, wherein said inflation device and said deflation device is a fitment comprising a pump and a release valve. 20. A method for manufacturing an inflatable bladder, comprising the steps of: (a) providing a first film having a first side and a second side;(b) applying a photosensitive barrier material to said first side of said first film;(c) providing a second film and positioning said second film over said first side of said first film, such that said barrier material is disposed between said first film and said second film;(d) ultrasonically welding said first film to said second film to form a sealed peripheral area, except in the area where said barrier material has been applied to said first side of said first film, to form at least one inflatable compartment corresponding in overall shape to a bladder configuration;(e) coupling an inflation device and a deflation device to said inflatable compartment, wherein said inflation device and said deflation device is a fitment coupled to said inflatable compartment at an opening through at least one of said first film or said second film and along a conduit formed between said first and second films; and(f) cutting along said sealed peripheral area to form a bladder having said at least one inflatable compartment and a sealed peripheral edge, wherein said inflation device and said deflation device permit selective, repeated inflation and deflation of said bladder. 21. The method of claim 20, wherein said inflation device is a pump and said deflation device is a release valve.
