Abstract
A packaging bag comprises a tubular body obtained by joining opposite ends of a strip film comprising a lamination of oriented and non-oriented films to each other so as to form a longitudinal sealed portion. The tubular body has at opposite sides in its diametrical direction crease portions, respectively, and has at opposite edges in its longitudinal direction lateral sealed portions, respectively. The crease portion has the first tearable zone, which can be torn at longitudinal different positions. The longitudinal sealed portion is located on the back surface side of the bag and has the second tearable zone, which can be torn at longitudinal different positions. The second tearable zone has a length identical with or longer than that of the first tearable zone. The upper edge of the second tearable zone is located in the same level as or above the upper edge of the first tearable zone and the lower edge of the former is located in the same level as or below the lower edge of the latter.
