Definitions

  • Packaging units for adhesive hygiene articles often include separating materials in order to prevent these products, which are adhesive on one side, from sticking together during storage or processing.
  • release materials must be distinguished by a good release effect against adhesives such as, for example, pressure-sensitive adhesives, hot-melt adhesives or other adhesive materials.
  • separating materials often have a coating, which can be based, for example, on silicone, on a carrier material, which can be based, for example, on paper, nonwoven fabric, and/or plastic.
  • release liners for informational, aesthetic, production, or other reasons.
  • colored tactile, control and/or pressure marks i.e. colored markings
  • these colored tactile, control and/or print marks then enable the separating materials and the products to be positioned precisely relative to one another using optical methods in a device provided for this purpose.
  • EP 0 519 611 A2 discloses a release liner comprising: (a) a reinforced nonwoven layered composite comprising two layers, one of the layers consisting of a plurality of substantially randomly oriented fibers and the other layer of substantially linearly aligned fibrous reinforcement material; and (b) a release layer on one or more of the layers of the nonwoven layered composite, the release layer comprising at least one of the following: an olefinic homopolymer, an olefinic copolymer, or a copolymer of an olefin and a polar comonomer.
  • US Pat. No. 9,212,299 B2 discloses release liner substrates and release liners produced therefrom, the substrate containing a coating layer which contains a binder and a hyperplastic talc.
  • the release liner may comprise a release liner substrate having a binder and a hyperplastic talc coating and a silicone coating applied to the substrate coating.
  • Release materials which are based on paper are also known from the prior art.
  • US 2008/0147028 A1 relates to a deodorizing separating layer for use in absorbent articles such as sanitary napkins.
  • One or more surfaces of the release liner are coated with an ink containing an odor control agent capable of reducing odors associated with a body fluid (e.g., menses, urine, etc.).
  • the release liner is initially positioned adjacent an adhesive located on the absorbent article. To use the absorbent article, the liner can be peeled off the adhesive and then disposed of (e.g., in a bin) either alone or with a used absorbent article.
  • a material section consists of a plastic film with a fleece applied to one side. On the side facing away from the fleece, the plastic film has a non-stick coating that is only partially applied. This structure is therefore also not air-permeable. Special measures against the loss of the textile-like character are not mentioned.
  • JP H06-63025 U relates to a sanitary napkin provided with an adhesive layer having sufficient adhesion against shorts when used, and releasability between the adhesive layer and the release layer provided on the packaging material.
  • a packaging structure for a sanitary napkin which is stick-free, is characterized in that an uneven portion is provided on at least an inner surface of the packaging material provided with a release liner.
  • the packaging units should be able to be opened with as little noise as possible and at the same time have a pleasant and skin-friendly feel and feel like a fabric.
  • the textile-like, soft character of the packaging material should not be changed too much in the course of the dehesive finish, but should be largely retained.
  • the separating forces which are required to detach the adhesive hygiene articles from the packaging units should be varied and should be able to be set to predetermined values or ranges.
  • the packaging units and the separating materials they contain should be able to be produced using sustainable and cost-effective processes with just a few steps.
  • the packaging units and in particular the separating materials they contain should be easy to recycle and not consume unnecessary resources in the form of additional material.
  • the packaging units and the separating materials they contain should be based on as few different materials as possible in order to improve recyclability.
  • the packaging unit according to the invention does not include any films, papers and/or products which are produced by crossing or intertwining yarns, as is preferred in weaving, warp-knitting, knitting, lace production and/or the braiding happens.
