ABSTRACT:
Methods and apparatuses for manufacturing air and water tight bags of plastic films such as Teflon or other fluorocarbons including creation of an intimate contacting pair of such films. This film pair can be stored or used in accordance with the other aspects of the invention or otherwise, and has its own utility. A vacuum table holds the film pair while a laser beam under computer control simultaneously cuts and welds the film pair along the path of the laser beam to form the bags.
