Definitions

  • the invention relates to the use of a web-shaped packaging material made of composite film, with at least one paper layer and a plastic layer, for packaging fatty food blocks, rolls or the like. At least one plastic layer of the composite film covering the paper layer against the fatty food on both Web edges protrude over the paper layer.
  • Web-like packaging materials of the type mentioned, in which at least one strip of plastic projecting beyond the width of the material web is provided, are known both from CH-PS 597053 and from DE-OS 29 46 739.
  • the packaging material webs described there are used in the manufacture of liquid-tight packs.
  • the material web is formed into a tube, an overlapping longitudinal seam is formed, in which the edge of the packaging material facing the filling material is covered by the plastic strip projecting beyond the base layer of the material web and this strip is sealed to the inner surface of the packaging material. This avoids open edges that come into contact with the product.
  • the invention is based on the object of proposing a packaging material for the use mentioned at the outset, with which the cited shortcomings are avoided and a flawless, sufficiently protective packaging is achieved.
  • This object is achieved according to the invention by the use of a web-shaped packaging material, a web width of the packaging material being divided into two blanks and each blank being placed around the food block or the food roll in such a way that the blank area comes into contact with the edge of the paper layer covered by the plastic layer the filling material stands and the cutting area with the open cut edge of the paper layer is folded loosely over it.
  • FIG. 1 shows a cross section through a web-shaped packaging material which has a paper layer 1 with a basis weight of 50 g / m 2.
  • This paper layer 1 is provided on one side with a print 2, which is protected against abrasion with a coating 3.
  • the other side of the paper layer 1 is covered in the extrusion process with a polyethylene layer 4, which has a greater width than the paper layer 1 and thus forms a protruding edge on both sides.
  • the packaging material web is cut through at the point indicated by an arrow between two printed images, thereby obtaining two blanks 8.
  • Fig. 2 shows a cross section through a further web-shaped packaging material, which consists of a paper layer 10 made of paper with a basis weight of 60g / m 2 , on one side of which a 9 ⁇ thick aluminum foil 6 is laminated with the aid of a polyethylene layer 5 of 12 g / m 2 is.
  • the aluminum foil 6 is provided with a print 20 on its side facing away from the polyethylene layer.
  • the other side of the paper layer 10 has a further polyethylene layer 40 with a basis weight of 25 g / m2 and a roughened surface, this polyethylene layer 40 is connected to the polyethylene layer 5, so that the edge of the paper layer 10 is completely covered.
  • FIG. 3 shows a perspective view of a packaging for rod margarine 7, using a blank 8 from the packaging material web according to FIG. 1.
  • the blank 8 is folded around the margarine block 7 in such a way that the polyethylene layer 4 is in contact with the margarine, the edge region with the polyethylene layer 4 projecting beyond the paper layer 1 coming first to lie on the margarine block 7 and the edge region of the blank 8 is folded over with the exposed cutting edge of the paper layer 1.
