Definitions

  • the invention relates to packaging with a block-shaped foodstuff-product, in which packaging a blank of a film-shaped packaging material having at least one layer is folded in an wrapping direction forming an overlapping region around four successive side of the block-shaped foodstuff-product and folded over two parallel, opposite lying sides, whereby for the purpose of opening the packaging the film-shaped packaging material can be separated along a tearing strip by pulling on a pull-off flap starting from the overlapping region in a direction opposite that of one of the wrapping directions.
  • Patent WO-A-01/25109 makes known a plastic film for packaging cube- shaped products such as soup cubes.
  • the plastic film made of a polyolefin, preferably of oriented polyethylene (OPE) or oriented polypropylene (OPP), is characterised by way of ease of folding.
  • the plastic film may be metallised on one side and may be provided with an adhesive or sealing layer, which e.g. is provided only where it is required. Further, a coloured layer, if desired with an outer lacquer coating, may be provided on the plastic film.
  • a form of packaging made up of a single layer plastic film having a tearing strip of tear-proof material that is attached to the plastic film and runs over four successive sides in the direction that the plastic film is wrapped.
  • the tearing strip is gripped at a free tab which is attached to the tearing strip and is pulled in the direction opposite the direction in which the plastic film is wrapped.
  • the plastic film tears along the longitudinal edge of the tearing strip which is attached to the plastic film and divides the packaging in two parts.
  • the - at least one - layer of the film-shaped packaging material is of a support material with at least one polymer film that is oriented in the direction of wrapping and the tearing flap is formed by a part of the packaging material in the overlapping region, whereby the tearing flap with side-limiting edges define the breadth of the tearing strip that can be torn out of the packaging film in the direction of orientation of the polymer film.
  • the tearing strip which according to the invention is integrated in the packaging material results, therefore, solely from the appropriate choice of packaging material.
  • the oriented polymer film may be monoaxial or biaxial oriented.
  • Essential is the direction of orientation of the polymer film with respect to the spatial orientation of the product to be packaged or the correlation of the orientation with the direction of wrapping, which in packaging machines normally coincides with the direction in which the strip-shaped packaging material runs or perpendicular to this.
  • a barrier layer against passage of gases, vapours, moisture, flavours, odours and/or substances causing smells, which may if desired be arranged on the support material, may be in the form of a metal foil e.g. made of aluminium.
  • suitable materials for barrier layers are e.g. films of plastics such as polyvinylidenchloride (PVDC) or ethylvinylalcohol (EVOH), or a layer of ceramic materials, such as e.g. silicon oxide or aluminium oxide or nitride, which are deposited in vacuum on the substrate material as a thin layer e.g. in the region of 10 - 500 nm.
  • PVDC polyvinylidenchloride
  • EVOH ethylvinylalcohol
  • ceramic materials such as e.g. silicon oxide or aluminium oxide or nitride, which are deposited in vacuum on the substrate material as a thin layer e.g. in the region of 10 - 500 n
  • metallising is a particularly suitable way of providing the substrate material, and thus the packaging material, with barrier action properties that prevent the passage of fluids, gases, vapours, water vapour, aromas, odours and/or substances causing smells.
  • Metallising also protects the contents from the harmful effects of light.
  • a preferred form of metallising employs aluminium which is deposited on the plastic film by sputtering or deposition in vacuum to a thickness of approximately 10 nm to around 2 ⁇ m.
  • a useful protective layer for the metallised coating is a lacquer with a nitrocellulose-based lacquer.
  • this first protective lacquer layer serves as substrate for printing.
  • the printing is likewise preferably provided with a nitrocellulose-based lacquer.
  • the printing on the plastic film bearing a metallised coating and a first protective lacquer layer may be performed using all known printing methods, e.g. typography, offset-printing, flexoprinting, screen printing, helio-gravure and copper-plate printing, but also by laser printing, inkjet, electrophotographic and magnetographic printing.
  • the choice as to which method of printing is to be used depends on the desired quality of print, on the prevailing technical conditions and the number of copies to be made.
  • the second protective lacquer layer protects the printed image.
  • the packaging material according to the invention is produced in roll form.
  • the packaging material is uncoiled from the roll and cut into individual sheets of film.
  • a special facility which in the case of soft cubes may be in the form of a piston - the sheets of film which form the packaging material for each individual block or cube to be packaged, are folded against the sides of the block, whereby the film is pressed against two opposite sides and overlaps on itself.
  • the packaged block or cube is then transported to a hot-sealing facility where the hot-sealing is carried out, fixing the film together in a permanent manner.

  • Cube-shaped packaging 10 shown in Fig. 1 comprises a film-shaped packaging material 14 wrapped over four consecutive sides A, B, C, D of a cube-shaped product 12.
  • the packaging material 14 overlaps on one side - in the drawing side A. In this region of overlap the inner side of the packaging material 14 lying facing the product lies on its outer side.
  • the packaging material is shown in the form of a tearing flap 16.
  • the tearing flap 16 becomes part of the tearing strip 30 which is integrated in the packaging material and runs round the packaging.
  • the packaging material is folded over these sides.
  • the packaging material 14 comprises a single or multi-layer support material 18 which is provided with a sealable coating 20 on the inside facing the cube-shaped product 12.
  • the outer side of the support material 18 is printed on and/or coated with a layer of lacquer 20.
  • the sealable region 26 provided on the outside of the packaging material 14 and the anti-stick layer 28 are deposited there in order to delimit the printing 22 or cover lacquer layer 24 in the case of register printing and, on the one hand, enable tight sealing of the inside of the packaging material to its outside as well as the possibility to grasp the tearing flap 16 in order to open the packaging.
  • the support material 18 may e.g. be a monoaxial or biaxial oriented polymer film with a direction of orientation lying in the direction of wrapping the four consecutive sides A, B, C, D.

  • the hot-sealing coating on the inside of the support material 18 may e.g. be a hot-melt or wax coating or a polyethylene-based polymer layer.
  • Figures 3 to 6 show various types and arrangements of tearing flaps 16. The broken lines indicate that the tearing strips 16 are not sealed to the underlying packaging material 14, which in that region is provided with an anti-stick layer 28 as in Fig. 2.
  • tearing flap 16 is provided in the middle between both sides E, F of the product 12 which is covered by the folded over packaging material 14.
  • Edges 17, delimiting the tearing flap 16 at the sides define a breadth e of tear- off strip 30 of polymer film employed as packaging material that can be removed from the packaging material in the direction of wrapping.
  • the side-limiting edges 17 of the tearing flap 16 extend over a short distance opposite that of the direction of wrapping in the form of cut lines 32, in the packaging material in the direction of orientation of the polymer film lying in the direction of wrapping.
  • tearing flap 16 is, as in Fig. 3, arranged in the middle between the two sides E, F of the product 12 enclosed by the folded packaging material 14.
  • tearing-aid notches 34 - in the direction of the polymer film orientation lying in the direction of wrapping - are provided at the transition of the side-limiting edges 17 of the flap 16 to the packaging material 14.
  • two lines of perforation 36 which correspond to the cut lines 34 in Fig. 3 are arranged parallel to each other at a distance corresponding to the breadth e of the tearing strip 30 that can be removed from the packaging material 14.
  • tearing flaps 16a, 16b are arranged a distance apart, close to the two sides E, F of the product 12 with the folded packaging material 14.
  • Each of the tearing flaps 16a, 16b exhibits the features of the tearing flap 16 in Fig. 4.
  • notches 34a, 34b are provided at the transition of the side-limiting edges 17a, 17b of tearing flaps 16a, 16b to the packaging material 14 are provided, in the direction of orientation of the polymer film lying in the direction of wrapping, these in order to help initiate tearing and lines of perforation 36a, 36b as aids to propagate the tears, viz., for each of the tearing strips 30a, 30b that can be removed from the packaging material 14.
