ABSTRACT:
An elongated flexible tube is formed with a plurality of sealing lines transversely of the tube in spaced apart relationship, a discontinuous cut line in the middle of each of the sealing line transversely of the tube and a discontinuous cut line in the shape of a continuous wavelike curve positioned transversely of the tube at the middle of the portion defined by each two adjacent sealing lines. The wavelike cut line defines at least two crest portions at the opening of each of a pair of inner bags to be formed on the opposite sides of the wavelike cut line. The inner bags, thus formed in a great number in a continuous tubular arrangement, can be separated along the cut lines for use.
