Definitions

  • a wrapper-type packaging made of a flexible polymeric film in the form of a sack or bag and consisting of a front wall and a rear wall, which are located opposite one another and are sealed in each case by a side sealing seam to form a sack-like or bag-like tube, of which the opening is covered by a closure flap which is formed by a projection of the rear wall and is folded onto the front wall at least as far as, and preferably beyond, the opening and is closed by in each case longitudinal side sealing and, optionally, transverse sealing or adhesive bonding, and preferably having an opening aid, wherein the flexible polymeric film is oriented at least monoaxially and is optionally embossed and has a tear propagation resistance in machine direction which differs by at least 30% in relation to the tear propagation resistance in the direction transverse to the machine direction and the wrapper-type packaging is suitable in particular for optionally self-adhesive articles, preferably optionally self-adhesive hygiene articles, which are preferably provided for single use.
