Definitions

  • This invention relates to a flexible sheet material fo use in packaging food products, particularly dry food product such as crisps, biscuits, nuts and cereals for example.
  • This invention particularly relates to sheet packagin material which incorporates holograms for decorative purposes.
  • Sheet packaging material for food packaging i conventionally supplied in roll form, in widths typicall between 650 mm and 1200 mm. These are considerably wider than conventional techniques allow for the production of sheet material embossed with holograms: for this purpose, a thermoplastic substrate is heated, impressed with an embossed platen and then cooled; but in order to ensure that an embossed relief pattern of the required uniform high quality is formed across the full width of the sheet material web, this web has been limited in width (typically to 200 mm) .
  • thermoplastic layer over a substrate, then forming a holographic embossed relief pattern in the surface of the thermoplastic layer.
  • thermoplastic layer carried by a substrate, it is possible to achieve a uniform high quality relief pattern across webs of substantial width, e.g. up to 1200 mm.
  • the thermoplastic layer may comprise an acrylic or a polyurethane. When heated, the thermoplastic layer softens and can then be embossed under light pressure from an embossing platen.
  • thermoplastic layer may be applied to the substrate in the form of an aqueous-based or solvent-based emulsion or lacquer and then dried.
  • solvent-based solvent is selected which is free of any toluene or methylethylketone, and which has a very low vapour pressure so that most, if not all, of the solvent is driven off during the drying of this layer.
  • solvent is ethylacetate.
  • Printing may be applied to the embossed surface of the thermoplastic layer, preferably after a metal (e.g. aluminium) film has been applied e.g. by vapour deposition or sputtering.
  • the printing is preferably protected by a layer of varnish.
  • a flexible sheet material which comprises a substrat carrying a thermoplastic layer which is formed over its oute surface with an embossed holographic relief pattern. Further in accordance with this invention, there i provided a package formed of the above-defined flexible shee material and containing foodstuff.
  • FIGURE 1 is an enlarged diagrammatic section (not to scale) through a first embodiment of flexible sheet packaging material in accordance with this invention
  • FIGURE 2 is a similar diagrammatic section through a second embodiment of flexible sheet packaging material in accordance with this invention.
  • FIGURE 3 is a similar diagrammatic section through a third embodiment of flexible sheet packaging material in accordance with this invention.
  • FIGURE 4 is a similar diagrammatic section through a fourth embodiment of flexible sheet packaging material in accordance with this invention.
  • the film 10 is provided in sheet or preferably roll form, comprising polypropylene of typically 30 to 40 microns thickness.
  • the film 10 is subjected to a corona discharge treatment over both of its surfaces, as indicated at 9 and 11.
  • a keying or priming coating 12 is applied, e. of polyurethane.
  • the thermoplastic layer 14 is applie in the form of an aqueous-based acrylic emulsion which is th dried.
  • the sheet material so far prepared (comprising laye 10, 12 and 14) is then passed lengthwise through an embossi apparatus, in which it is warmed to soften the thermoplast layer 14, then impressed by a holographic master to fo holograms embossed in relief in the surface of the layer 14 and then cooled to preserve the embossed relief pattern.
  • Thi embossed relief pattern is indicated at 15.
  • metal typically aluminium
  • printing is applied over the coating 22a and the this surface is coated with adhesive 23a for bonding to th aluminium film 26.
  • the printing may instead be applied to th film 26 before the bonding takes place.
  • the printing i visible through the transparent layer 20a and the holograms ar visible through this layer, through the printing (or throug non-printed areas between printed areas) and through th aluminium film 26.
  • the embodiment shown in Figure 3 comprises polypropylene film substrate 30 of typically 30 to 40 micron thickness with an acrylic heat seal layer 32 over one surfac and an acrylic thermoplastic layer 34 over the other surface
  • An embossed relief pattern, indicated at 35, is formed in th layer 34 in the manner previously described, and then th aluminium film 36 is applied.
  • the sheet material is the printed over the film 36 and coated with varnish , also a previously described.
  • the embodiment shown in Figure 4 comprises polypropylene film substrate 40 coated over one surface with a pvdc heat seal layer 41 and over the other surface with an acrylic primer 42 to which an acrylic solvent-based thermoplastic layer 44 is applied.
  • a solvent is selected which is free of toluene or methylethylketone, or at least such that after drying the thermoplastic layer contains no more than lOmg ⁇ per square metr of retained toluene or methylethylketone.
