Definitions

  • This invention incorporates magnetic receptive media combined into the formulation of a standard extruded film.
  • Products now available to the print market combine a commercially extruded film and a magnetic receptive coating applied after the extrusion process. This produces a one-sided printing film that will adhere to magnets.
  • This new invention is showing the advantages of the incorporation of magnetic receptive media in the formulation of the extrusion process, which can yield a print media that has magnetic receptive properties and maintains a print surface on both sides.
  • This pigment is typically present in a 0.5% to 5% weight ratio.
  • magnetite powder or other ferromagnetic particles in the size ratio between .01 ⁇ to 30 ⁇ at a weight ratio between 15% and 70% by weight. This is a considerably higher load than practiced in the industry.
  • U.S. Patent 4,345,005 discloses the use of additives to enhance adhesion of metallized coatings. Electron beam curing in a reactive setting, cures these coatings. This process is incapable of adding material that a magnet will adhere to.
  • This invention is based on the incorporation of magnetic receptive media in a conventional extrusion process coupled with the ability to co-extrude a top and bottom layer suitable to accept printing.
  • This approach has not been taken in the extrusion process, using higher than what is perceived as normal loads of filler in the polymer to produce a film with strong magnetic properties suitable to adhere to magnets and multilayer one on top of the other.
  • This invention will reduce waste in the industry and present a more environmentally responsible option.
  • the used product can be shipped back to the factory and master batched into the core layer. This is possible due to the white printable outer layers that conceal the magnetic receptive core.
  • a mixture of polypropylene resins compounded with magnetic receptive particles in a 25% load by weight formulated to be compatible with extruding films is co-extruded with a top and bottom layer sandwiching the magnetic receptive layer in between. It is important to adjust the flow temperature between the first layer and subsequent outer layers. Having the high load of magnetite or other ferromagnetic media, will act as a heat sink and cause a slower cooling. The addition of high loads of clay or calcium carbonate in the outer layers can help compensate the embodiment difference. This will also add to the print receptiveness of the surface layer.
  • the co-extruded web can be followed by stepwise orientation, both in the longitudinal and transverse direction. Micro- voiding and cavitation techniques can be applied to this invention as process employment.
  • the preferred melting points of the polymer are between 400°F and 600 0 F
