Publication number: 20130133294Abstract: The invention relates to a method for the preferably continuous packaging of products, in particular foods, with or without an already stabilized inherent shape such as fresh meat, meat products and sausage products, sausage meat emulsion or similar products by encasing them on all sides with single-layer or multilayer films that can be fed from the web. According to the invention flexible films that can be deformed without the action of heating and are self-resetting, are used as bottom web films, wherein the bottom web films are temporarily deformed by the action of pressure in order to form troughs for receiving product. The respective product is introduced as portions into the trough and fixed there, wherein it is fixed by a top web film or covering film, optionally supported by a restrainer.Type: ApplicationFiled: March 31, 2011Publication date: May 30, 2013Applicants: TRITON GMBH, NORDENIA TECHNOLOGIES GMBH, DEUTSCHES INSTITUT FÜR LEBENSMITTELTECHNIK E.V.Inventors: Fritz Kortschack, Volker Heinz, Stefan Töpfl, Bernhard Hukelmann, Herbert Bader, Ralf Niepelt

Publication number: 20130082422Abstract: A molded article is made by first providing a starting material comprised of a support web and a layer of expandable polymer particles on the support web. This starting material is fitted as several layers into a generally closed cavity of a mold or shaping shell so as to only partially fill the cavity. Then energy, for instance microwave radiation, is applied to the starting material in the cavity so as to expand or foam the polymer particles such that the starting material generally fills the cavity.Type: ApplicationFiled: September 28, 2012Publication date: April 4, 2013Inventors: Herbert BADER, Ralf NIEPELT

Patent number: 8272511Abstract: An article of commerce includes a disposable cleaning article and a package. The package exhibits soft visual and sound characteristics. The package is formed as a multilayer packaging film including at least a co-extruded vapor barrier film layer and a polymeric film layer having a melting point at least about 20° C. less than the co-extruded film layer. The polymeric film layer is sealable to form the package so as to enclose the disposable cleaning article, thereby to substantially retain the water content of the disposable cleaning article. The polymeric film layer further exhibits a corrected sound level of less than approximately 50 decibels at readily audible frequencies, such as 3-5 kHz. The reduced sound level may be achieved by providing a film with a high loss tangent. In addition, the multilayer packaging film may have an outer surface with a soft or “matte” appearance.Type: GrantFiled: October 19, 2005Date of Patent: September 25, 2012Assignee: The Procter & Gamble CompanyInventors: Martin Zethoff, Philip Andrew Sawin, Ravi K. Saggar, Matthew Aaron Neumann, Edward John Milbrada, Ralf Niepelt, Luis Alberto Santini Torres

Patent number: 7601658Abstract: The invention relates to an elastic laminate. The laminate is made from a co-extruded elastic film, comprising an elastomeric support layer, at least one cover layer and at least one textile outer layer made from a non-woven. The cover layer has a low layer thickness by comparison with the support layer. The outer layer is laminated onto the cover layer. According to the invention, the cover layer is made from an elastomeric material, with essentially the same expansion properties as the material of the support layer and contains additives for modification of the surface properties.Type: GrantFiled: July 20, 2005Date of Patent: October 13, 2009Assignee: Nordenia Deutschalnd Gronau GmbHInventors: Andreas Hagemann, Ralf Niepelt, Henner Sollmann, Georg Baldauf
