  • This invention relates to a method of combined in-mold labeling (hereinafter sometimes referred to as "IML" for short) and embossing of a packaging product as well as a facility for combined in-mold labeling and embossing of a packaging product.
  • IML in-mold labeling
  • Thermoforming is a technique for producing plastic packaging.
  • the process is based on the heating of a thermoplastic film or sheet (hereinafter collectively referred to as "film” for simplicity), which then takes the spatial shape of a tool mold (namely, the cavity, referred to in the English as “mold” for short).
  • film a thermoplastic film or sheet
  • Thermoform IML means that the decoration of the product takes place during thermoforming.
  • the IML label is bonded to the heated film while the finished packaging part is molded.
  • the end result is a packaging part decorated in a single operation.
  • IML in-mold-labeling
  • the in-mold process (or in-mold process) is used primarily in injection molding but also in thermoforming as in-mold labeling.
  • thermoforming or injection molding substrates such as fabric, paper, wood veneer or any printed or structured films are back-injected.
  • substrates such as fabric, paper, wood veneer or any printed or structured films are back-injected.
  • the in-mold process is used in the construction of sports helmets (especially bicycle, ski and snowboard helmets). In this process, the shell and the rigid foam are welded together. The result is a complete connection and a very stable helmet structure - the safety under mechanical impact (eg when falling on a pointed object) is significantly higher than with helmets that are only glued (usually pointwise). InMold helmets are also much lighter and more durable.
  • the invention has for its object to provide the prior art an improvement or an alternative. This object is achieved by a method for in-mold labeling and embossing of a packaging product in a combined EVIL embossing tool for a thermoplastic film, wherein a label is used and wherein in the region of the label an embossment is produced, which has a mechanical edge.
  • embossing is the introduction of a local survey or depression from the otherwise continuous surface of the processed film. It is expressly not necessary to use a conventional “embossing” tool, rather “embossing” can also be done as a molding of the "embossment” into the film as a result of thermoforming, in practice the Applicant currently assumes that the most cost-effective and fastest in production production will be embossing molding.
  • the combined tool will usually be a negative tool.
  • negative molding ie thermoforming into a negative tool
  • the outside is the more precise side to be produced.
  • Exactly the outside, however, is the decisive factor in the production of a thermoforming packaging, which is relevant here, because the customer of the goods first encounters the outside of the packaging.
  • a local depression is introduced into the shell, for example a lettering in the form of an inscription, then during the thermoforming process the film also forms into this local depression. In the formed surface of the film, the local increase then stands out as a precise relief.
  • thermoforming Through the superimposition of EVIL and embossing, targeted stresses can be achieved on the packaging produced by thermoforming, which can lead to comfort or safety advantages, for example.
  • a label is used with a color edge, and the color edge is brought into contour coincidence with the mechanical edge.
  • a "color edge” may be either the area between a colored area of the label, such as a logo, an image, a lettering, a graphic, or the like, opposite the background of the label, which may also have a color, but in a preferred embodiment the background does not have its own color, but is colorless.
  • the edge can be emphasized by the at least partially running-together of the two edges.
  • safety-relevant markings, seals, straw puncture marks, snap closures or the like can be highlighted in color by means of embossing and edge contour matching.
  • the refraction of the light also changes abruptly at the edge of the embossing - depending on the design of the negative tool, in particular on the edge sharpness there
  • the label is embossed together with the film.
  • the label is introduced in a conventional manner in the EVIL tool, especially inserted, then connected in a thermoforming process with the film stabilizing, and on the composite of film and label affects the embossing tool, especially for example an embossing die, the time after the connection can be pressed by label and foil in the film. Or the embossing is done by negative or positive molding. On the other hand, it is conceivable that the label is embossed separately from the film.
  • the label is first embossed or completely embossed in the EVIL tool, and only then is the thermoforming compound made with the film.
  • An embodiment of the invention provides that an intelligent component is attached to the label.
  • an “intelligent component” is in particular passive electrical circuits to understand, for example, RFID tags, active circuits, ie circuits with their own power supply, bar codes or other machine-readable information carrier.

  • the label may have a hologram.
  • the label may have a haptic surface, that is to say a surface which differs in feel from the surface of the thermoformed film when perceived by a human finger.
  • the stated object solves a system for combined in-mold labeling and embossing of a packaging product, wherein the system is adapted to use a label, which has a color edge, and wherein the system is set up , an "embossing" - according to the application defined in the context of the present patent application - to produce with a mechanical edge, the system is preferably additionally arranged to bring the color edge with the mechanical edge in contour match, especially so the mechanical edge Using a die, a local depression or a local elevation in the negative tool to produce contour matching with the color edge on the label.
  • the single figure shows, in a spatial view, a flat area of a packaging with a thermoformed shape from a film plane
  • the container shown in the cutout is manufactured in the thermoforming process.
  • embossing is applied, either with an embossing stamp from the inside or from the outside of the packaging container, be it by means of a local depression in the tool, ie a negative inscription in the negative tool.
  • At least one of the edges of the lettering, which is spatially highlighted by the embossing is in agreement with a colored edge.
  • the colored edge can either be just about the length of the edge of the Embossing extend, or it may run over, for example, when the colored edge on the side surface of the packaging container runs, then merges into the embossing edge and then continues, for example.
  • the embossing is highlighted in color.
  • a printing or stamping with a color can take place, preferably on the contour protruding from the embossing with respect to the surrounding surface of the film, in this case the sequence of letters.

Abstract

L'invention concerne un procédé d'étiquetage dans le moule et d'estampage d'un produit d'emballage ainsi qu'une installation servant à combiner un étiquetage dans le moule et un estampage d'un produit d'emballage. Le thermoformage est une technique de fabrication d'emballages en plastique. Le procédé repose sur le chauffage d'un film ou d'une plaque thermoplastique, lequel/laquelle prend alors la forme spatiale d'une moule. Lors de l'étiquetage dans le moule par thermoformage, la décoration du produit a lieu au cours du thermoformage au moyen d'une étiquette d'étiquetage dans le moule. Selon l'invention, lors d'un procédé servant à étiqueter dans le moule et à estamper un produit d'emballage dans un moule combiné pour un film thermoplastique, une étiquette est insérée, et un estampage est pratiqué dans la zone de l'étiquette, lequel présente une arête mécanique.
