Abstract
At least one surface of a paper sheet of a composite paper sheet utilized to form bags is printed with a printing ink type binder. The binder is printed in the form of parallel spaced stripes extending in parallel with or crossing at a predetermined angle with respect to the longitudinal direction of the composite sheet. After printing, the composite sheet is wrapped into a roll. Then, the printed binder bonds adjacent paper sheets together to form the composite sheet. The binder can be applied with conventional printing press.
