Definitions

  • the present invention relates to a process for making a laser coded fold wrapped food concentrate tablet. Further aspect of the invention is a laser coded fold wrapped food concentrate tablet.
  • Document EP 2 090 524 discloses the packaging of a blockshaped foodstuff-product, in which packaging a blank of a film-shaped packaging material having at least one layer is folded in a wrapping direction forming an overlapping region around four successive sides of the blockshaped 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.
  • the object of the present invention is to improve the state of the art or at least provide an alternative to code a fold wrapped food concentrate tablet.
  • the objective is to provide a coded fold wrapped food concentrate tablet and process to make such coded food concentrate tablet: i) no contaminants release of the coding e.g. ink; ii) no smearing of the coding; iii) no contamination of food due to coding; iv) no coding residues to machineries; v) no contamination to fingers of operators; vi) less production stoppages caused by refill of coding material; vii) a good readable code; viii) a coding which is suitable for high speed production lines; ix) a system which is suitable to code at least 30000 characters in a minute; x) no drying time of the coding material; xi) no environmental impact of empty ink cartridges or ink barrels.
  • the present invention provides in a first aspect a process for coding a fold wrapped food concentrate tablet comprising the steps of:
  • the invention in a second aspect, relates to a coded fold wrapped food concentrate tablet, wherein the food concentrate tablet is fold wrapped with a packaging material, wherein the packaging material comprises a printed plastic film and/or printed paper film and wherein the coding is made by laser ablating of a packaging material.
  • laser ablating a code on a packaging material of a fold wrapped food concentrate tablet has certain advantages.
  • the coding is very good readable and there is no possible smearing. There is no abrasion of the coding during further packaging processing steps even the coding is done before fold wrapping the food concentrate product. Also no drying step has to be considered which reduce production time.
  • the laser ablating can be performed within a high speed fold wrapping packaging process. Also there will be no contamination of machineries or the food concentrate tablet itself with a coding material e.g. with an ink. Moreover, the laser ablating can be done in any direction.
  • the present invention pertains to a process for coding a fold wrapped food concentrate tablet comprising the steps of:
  • food concentrate tablet refers to a bouillon or seasoning tablet or to a chocolate and malt tablet, preferably to a bouillon or seasoning tablet.
  • laser ablating refers to a coding wherein the laser removes material to create depth which change the color, contrast or reflectivity of the surface.
  • laser ablating at least a printing layer of the packaging material is removed.
  • laser ablating a printing layer and also the metallization layer of the packaging material is removed.
  • code refers to any digit, letter, character, number, symbol and/or logo. In an embodiment the coding refers to an expiry date, production number, batch number and/or manufacturing date.
  • the principles of laser coding involves reflecting an intense light beam off mirrors, through a stencil, and onto the material to be coded.
  • the laser beam generated by a gas (e.g. CO2) or solid state type of laser is guided onto the surface to be coded via a 2-axis beam guidance optic situated about 50 -200 mm above the surface allowing a coding field being of size 50 x 50 - 200 x 200 mm.
  • the code itself has a size of 1 to 4 mm height and width.
  • the area of the surface to be coded is shielded with a Laser safety housing.
  • the safety housing is connected with a fume extractor in a way that within a continuous air flow the gases generated by the coding process are transported to the filter equipped fume extractor.
  • the wavelength of the laser is between 0.4 ⁇ m to 11 ⁇ m, preferably between 1 ⁇ m to 11 ⁇ m.
  • the position of the laser coding is controlled by means of a print-mark sensor and the speed by means of an encoder.
  • fold wrapped refers to a process of folding a packaging material around a food concentrate (tablet) including sealing of sides and bottom of the packaging material. It is not that a food concentrate (tablet) is fed into a plastic tube and fin sealed at the bottom and sealed on the sides. Fold wrap does not have an external excess packaging material. The food concentrate is not loosely contained within the packaging material.
  • tablette means a tablet or cube obtained by pressing a free flowing food concentrate powder into a tablet or cube form.
  • packaging material refers to a plastic film and/or paper film.
  • the packaging material comprises a printed metallized plastic film and/or a printed paper based film.
  • printed refers to at least one printing layer of color at the plastic film and/or paper based film.
  • metalized refers to at least one metal layer within the packaging material, preferably it refers to an aluminum layer.
  • the packaging material is a plastic film, especially for packaging rectangular objects such as stock cubes, comprising a base film which is metallized (preferably with aluminum) on one side consisting of oriented polypropylene (OPP) film or polyethylene terephthalate (PET) film or oriented polyethylen (OPE) with printing on the metallized layer and an outer layer of heat-sealing varnish.
  • OPP oriented polypropylene
  • PET polyethylene terephthalate
  • OPE oriented polyethylen
  • an opaque and oriented polypropylene film is used as the base film, preferably including a white cavitated OPP and clear OPP skin.
  • the opacity of the base material film is done by orientation of the polymer and by adding fillers. The cavitation are, produced by adding fillers and/or air into the film.
  • the packaging material has a thickness of 10 to 100 ⁇ m, preferably 20 to 80 ⁇ m.
  • the packaging material is a plastic film that has a base film which consists of an opaque and oriented polyproplyene (OPP). This base film is provided with metallization on one side. To improve bonding, the metallization is coated with a primer on its side facing away from the base film, inks are then applied on the primer. A pattern of sealing lacquer is applied to this printing, helping the film to be sealed at higher temperature. An over lacquer is printed in the area where no seal lacquer is applied.
  • OPP opaque and oriented polyproplyene
  • the invention further relates to a coded fold wrapped food concentrate tablet, wherein the coding is made by laser ablating of a packaging material.
  • thermos-inject (TIJ) coding by printing a stop is needed at least once a day and normally at least every 8 hours.
  • CIJ continuous inject
  • CIJ continuous inject
  • Fig 1 the overlapping packaging area (2) of a side fold (1), bottom fold (6), envelope fold (4) wrapped food concentrate tablet or cube (5) is shown.
  • a packaging material comprising a printed Al-metallized plastic film with oriented polypropylene (OPP) has been laser coded by removing the ink layer of the plastic film using a CO2-20W-9.3 ⁇ m-laser.
  • a focus distance of 140mm provides a 100mm x 100mm coding area with 28 digits coded within 3 lines mentioning an expiry date, manufacturing date and production line).
  • a bouillon tablet has been fold wrapped using a Theeberg BCW3 machine resulting in a side fold (1) wrapped bouillon tablet with the laser coding in the overlapping packaging material as shown within Fig 1 a) .
  • 1200 tablets can be laser coded and fold wrapped.
  • Example 1 fulfilled all objectives discussed above (see i)-xi)) compared to a coding with ink.
  • Moisture uptake measurements were carried out in SPS 1 ⁇ (ProUmid GmbH, Germany). Bouillon tablets of 10 gr and a water activity of 0.35 were placed in a 52 mm pan and exposed to controlled temperature of 25 °C and relative humidity of 75 % for 10 days. Weight of the samples was automatically monitored and moisture uptake was measured in mg/tablet after 5 and 10 days. Measurements were carried out in duplicate.
  • Examples 2.1 and 2.2 have been laser coded before wrapping the bouillon tablet. All examples will result in a shelf stable product for several months (at least 3 months). Nevertheless as can be shown within example 2.1 (laser coded within an overlapping area) the moisture uptake is only the half compared to example 2.2 (laser coded within a non-overlapping area) and is similar to a wrapped bouillon tablet without any laser coding. Therefore example 2.1 guarantees the same shelf-life of a laser coded bouillon tablet as a not laser coded bouillon tablet.
