To provide a laminate bag with which sufficient body sticking strength can be obtained with a minimum used amount of a laminate sheet.
When a paper 3 is to be laminated on a paper or a plastic film 2, one of side ends of the film 2 is made to extend out of an end of the paper 3 to provide a film body sticking part, and the other end 3b of the paper 3 is extended from the other side end of the film 2 to provide a paper sticking part. Since this laminate sheet 6 is pasted into a cylinder 7 with the film 2 inside, a used amount of the laminate sheet 6 is minimum. In addition since sticking is done between the same material wherein the film 2 is stuck to the film or the paper 3 is stuck to the paper, adhesion strength can be easily obtained. When the plastic film is used as the inner film 2, lack in adhesion between the paper 3 can be compensated by adhesion between the plastic films, so that required body sticking strength can be extremely easily obtained.
