Definitions

  • the invention describes a package with a pre-cut opening which can be repeatedly opened and closed, in particular flexible packaging such as tubular, upright and log bottom bags, thermoforming trays, also folding boxes or any kind of packaging made of sheet-like materials such as Sheets, composites or paper and cardboard boxes is produced.
  • flexible packaging such as tubular, upright and log bottom bags, thermoforming trays, also folding boxes or any kind of packaging made of sheet-like materials such as Sheets, composites or paper and cardboard boxes is produced.
  • packages are opened by separating a weld, seal or bond, so that the package is irreversibly opened, with the result that they can not be closed again - without additional aids such as plastic clips.
  • single-layer labels are used to open and close such packages. These are labeled via a removal hole previously cut in the package, from which parts of the contents are later removed from the packaging.
  • a disadvantage of such single-layer labels is that the pressure-sensitive adhesive has to fulfill two conflicting functions: it must allow easy opening with little effort, and the label must then, when reclosed, have sufficient adhesion to seal the package securely and tightly.
  • the problem with such labels is further that they curl up when opening, due to the direct bonding on the packaging material and thus the label is irreversibly deformed, which can lead to self-opening during subsequent reclosure.
  • two-ply labels are offered which avoid the disadvantages mentioned by the label consists of two label layers, which are glued on top of each other.
  • two pressure-sensitive adhesives are present.
  • the lower adhesive ensures a secure and tight bond to the packaging, while the second adhesive is on a dehasive layer located on the surface of the lower of the two label layers. This allows easy opening without the described deformation of the label.
  • a removal hole is present on the lower label.
  • the single-layer and the two-layer labels must be subsequently applied to a pre-cut in the packaging extraction hole in an additional operation.
  • This operation can either take place at the packaging manufacturer or be integrated in the filling process.
  • the removal hole is punched out previously and prevented by means of so-called breakpoints from falling out before the label is glued over it. It is advantageous, but not absolutely necessary, for the labeling to take place immediately after the punching of the removal hole, in order to prevent unwanted separation of the stamped part of the removal hole. Incidentally, the punching of the removal hole can also take place after the application of the label.
  • the packaging film itself consists of a two-layer composite, which can be delaminated.
  • an opening and reclosing system is realized.
  • the punching of the lower foil is made slightly smaller than that of the upper foil.
  • the difference in the size of the two punches results in a circumferential closed edge around the punch hole.
  • the package is glued before opening, according to the size of this edge and the adhesive force of the two films on each other, which can be delaminated.
  • This system only partially meets the requirements in the market.
  • the adhesive force is many times higher at the first delamination than at the subsequent reclosure.
  • a safe and dense reclosing is possible only to a limited extent, so it can cause the contents of the packaging to dry out.
  • this system limits the choice of packaging materials as it is limited to the composites offered. Integration into existing packaging solutions is therefore not possible. This results in decorative restrictions such as the use of highly transparent bags or product-related restrictions such as the use of special barrier layers, etc.
  • Object of the present invention is to provide a package that is easy to open for the first time and can be reversibly opened and closed safely.
  • the packaging is made from sheet-like materials such as foils, composites or paper and cardboard.
  • the packaging is preferably a flexible packaging, for example a tubular bag for oil-soaked wet wipes (known as baby or make-up wipes).
  • the packaging may be a pouch packaging of any kind for the packaging of foods such as sweets, biscuits, chocolates, candies, nuts, gummy bears, chips, etc.
  • the packaging may be a thermoforming tray in which cheese or sausage slices be packed.
  • the packaging according to the invention is suitable for all non-liquid goods which are usually not used up completely after the first opening, especially for goods which are to be protected from moisture, dehydration, odor discharge and / or entry by resealing.
  • a dehesive finish is preferably applied to the packaging body, except on the lid (around the pre-cut opening), before the label closing the opening is glued.
  • the area of the dehesive equipment corresponds exactly to the area which covers the carrier material of the label.
  • the contour of the coating corresponds to the contour of the overlying label (with the possible exception of a later described in more detail edge region of the label).
  • the coating is applied in the form of a disk adapted to the contour of the opening (for example circular disks if the opening is circular).
  • the label After removal of the contents, the label can be reversibly applied to the packaging again, the bond strength of the coordinated release behavior (Release) of pressure-sensitive adhesive and Dephasesiv-layer guarantees a good adhesion even with repeated opening.
  • the denzosive equipment is not over the entire area around the pre-cut opening (preferably outside the lid) available, but recessed in a region, so that the label with a strip sticks directly to the packaging casing in the edge area. This results in the already described hinge in the label, which prevents the label is detached when opening.
  • the bond strength between label and packaging is so great that separation is only possible by force.
  • the label is attached here partially non-detachably glued to the packaging jacket.
  • This puncture may be a perforation, optionally in the known and proven waveform. This reduces the return forces of the label, and the label does not fall back (at least not so easily), that is, the package remains open without the need for a hand to hold it open.
  • the hinge can be formed by using two different adhesives on the carrier material. Most of the backing material is coated with an adhesive that will dislodge well from the dehiscence area, while a second area of the backing material is provided with a high tack adhesive that prevents unwanted peel-off of the label in that area.
  • the adhesive can be chosen such that it anchors itself on the packaging body, which may also be dehesively equipped in this area.
  • packaging materials are printed, varnished or laminated in various ways. Frequently composite materials are used, so that the printing is applied to the inside of a laminating composite. In this case, no paint or varnish layer is applied on the outside of the package.
  • packaging in which the printing and painting is applied to the outside.
  • the coating is full-surface in this case, in some cases, a partial coating can be used.
  • dehesive aids are added to the paint, but this is usually done for technical or decorative reasons, for example, to achieve a special gloss or to change the friction values of the surface.
  • the adhesive layer serves solely to provide a defined release label release behavior from the package.
  • the dehesive layer is in each case partially applied and recessed at least at the location of the lid.
  • an opening is cut, preferably by a punching process, thereby creating a lid in the package.
  • the cut or the punching is made such that the edge region of the lid is weakened, so it can be easily torn open.
  • the punching can also be done so that the lid is prevented by means of so-called breakpoints from falling out, depending on the geometry of the lid and the physical properties of the material of the packaging, the size and number of breakpoints vary. As breakpoints small interruptions in the punching tool are referred to, which do not punch the packaging at this point and thus fix the lid in the package. In later use (opening the package by the customer) tear these small breakpoints without affecting the function.
  • the labeling is carried out immediately after the punching of the opening in order to prevent a separation of the lid.
  • the punching of the lid can also be done after the application of the label, which involves the risk of injuring the label by the punching process.
  • the lid which advantageously closes the opening, is preferably not fully equipped (optionally apart from a customary tolerance to be observed in the production process), so that when the label is first closed the lid is glued to the carrier material located above it.
  • the carrier material covers the lid and this, so the punched-out part of the packaging body remains connected to the label and is removed from the opening, the line of weakness tears.
  • the substrate has a grip, more preferably on a side opposite to the side where the hinge is formed.
  • a surface is free of adhesives or the bond strength is reduced. This surface then serves as a handle for gripping and peeling off the carrier material.
  • Another way to make a handle is to cover the adhesive forming the surface by a release paper, so that the adhesive can have no effect. Furthermore, the adhesive in this area can also be neutralized, for example by printing or powdering.
  • This handle can also be formed by integrally forming an additional adhesive-free surface on the carrier material.
  • the design of the label is done individually according to the customer's wishes.
  • the size and shape of the label is arbitrary, as is the possible printing. Further preferably, the label is substantially rectangular, where appropriate, the corners are rounded.
  • films or composite materials to choose from preferably films of PP, PE and PET, which further preferably have a thickness of 20 and 100 microns, especially between 25 and 65 microns, most preferably between 50 and 60 microns ,
  • films can be used as materials, in particular monoaxially and biaxially oriented films based on polyolefins such as PE or PP, then films based on stretched polyethylene or oriented copolymers containing ethylene and / or polypropylene units, if appropriate also PVC films, PET films. Films, films based on vinyl polymers, polyamides, polyesters, polyacetals, polycarbonates.
  • Biaxially oriented polypropylene is characterized by its very high tensile strength and low elongation.
  • Preferred for the production of the labels according to the invention are biaxially oriented films based on polypropylene.
  • the thicknesses of the biaxially oriented films based on polypropylene are preferably between 20 and 100 ⁇ m, in particular between 25 and 75 ⁇ m, very particularly between 30 and 65 ⁇ m.
  • Biaxially oriented films based on polypropylene can be produced by blown film extrusion or by means of conventional flat film systems. Biaxially stretched films are produced in one or more layers. In the case of multilayer films, the thickness and composition of the different layers may be the same, but also different thicknesses and compositions are known.
  • Suitable for the labels according to the invention are monolayer, biaxially or monoaxially stretched films or multilayer, biaxial or monoaxial films based on polypropylene, which have a sufficiently strong bond between the layers, since delamination of the layers during use is disadvantageous.
  • Films based on rigid PVC are used for the production of labels as well as films based on soft PVC.

  • a pressure sensitive adhesive is a viscoelastic composition that remains permanently tacky and tacky at room temperature in a dry state. The bonding takes place by light pressure immediately on almost all substrates.
  • Suitable masses are for example in the " Handbook of pressure-sensitive adhesive technology, second edition, edited by Donatas Satas, described by Van Nostrand Reinhold, New York, 1989 s.
  • the self-adhesive composition used is in particular a commercially available pressure-sensitive adhesive composition based on PUR, acrylate or (synthetic) rubber, preferably a UV-crosslinkable hot-melt pressure-sensitive adhesive mixed with additives and resins.

  • the bond strength with which the label is glued in the area on the packaging, which has no depatisive coating, are to be chosen so that the label in the hinge area can not be separated or only by force. Likewise, the bond strength must be sufficiently high that, when the label is peeled off, the breakpoints of the precut aperture are torn open.
