摘要： A method and a machine for making a plastic film bag with opposed closable end openings as well as a double compartment bag is described. The bags may be formed from J-folded, U-folded or tubular film sheets. In one embodiment, a bag is formed with a gusseted end adjacent which a zipper closure and a detachable end is provided and at the other end of the bag there is provided an opening which is closable by a closure tag. The method and machine are also adaptable to form double-ended closure bags having two distinct compartments, each accessible by a respective one of the end closure. The bags formed by the method and machine have various uses such as carrying two separate articles, each article being accessible from one of the opposed ends of the bags. The double compartment bags may also contain two different products, each accessible separately through a zipper closure. The bags may also be formed with a flap provided with wicket holes to support the bag in an automatic bag filling machine.
