Definitions

  • the invention relates to an edge stiffening for the opening area of plastic bags and the like according to the preamble of claim 1.
  • edge reinforcements for example known from US Pat. No. 4,379,519, a flexible plastic band is folded in a U-shape, placed over the edge in the opening region of the bag and held there with clips.
  • the folding of the plastic tape is relatively cumbersome here.
  • the fastening of the band by means of clips is expensive.
  • the bag cannot be given any shape in the opening area.
  • the object of the invention is therefore to provide an edge stiffening of the type mentioned, which is easy to fold in a U-shape and easy to attach and with which the bag opening can be given any shape.
  • the edge stiffening shown in Fig. 1 for plastic bags and the like is made of a stable, but easily deformable plastic tape (1).
  • An embossed crease line (2) runs along the center of the outside of the plastic band (1), which enables the plastic band (1) to be folded inwards without problems.
  • plastic belt part (la) runs in the longitudinal direction, reaching the fold line (2), a flexible reinforcement (3) of thickness matched to the bending stiffness of the plastic belt (1) in the form of a metal strip, which is connected to the Plastic strap part (la) is firmly connected.
  • This reinforcement (3) can also consist of metal wire, as shown in FIG. 2, or of metal mesh, as shown in FIG. 3, or another material which gives the plastic band (1) greater dimensional stability.
  • the reinforcement can also be attached to the inside of the plastic band part (la) as shown in FIG. 4 by gluing or lamination.
  • Both plastic tape parts (la and lb) are equipped on the inside with a self-adhesive layer (4 and 5), which is covered by removable protective strips (6 and 7).
  • the edge reinforcement is attached to a plastic bag as follows:
  • a piece of the edge reinforcement corresponding to the desired extent of the later filling opening is cut taking into account an appropriate addition.
  • the protective strip (6) is pulled off the reinforced plastic tape part (la), the plastic tape (1) with the self-adhesive layer (4) is formed into a ring on the inside and glued on top of each other according to the addition.
  • the open edge of the plastic bag is glued along the middle of the plastic tape (1) to the self-adhesive layer (4) and thus connected to the reinforced plastic tape part (la). If the size of the opening area of the Plastic bag too large, it can be adjusted by folding.
  • this plastic tape part (lb) After removing the protective strip (7) from the plastic tape part without reinforcement (lb), this plastic tape part (lb) is folded inwards and glued by means of the self-adhesive layer (5) onto the plastic bag edge adhering to the reinforced plastic tape part (la).
  • edge of the plastic bag is stabilized by the edge reinforcement and can be bent into the desired shape.
