Patent number: 6413605Abstract: An adhesive preventing system containing a flexible tape member that may be in the form of either a sticker or an elongated tape is disclosed. This flexible tape member has an upper and a lower side and has two patterns printed on the upper side of the flexible tape member, one of which is printed with a material that is capable of bleeding through the flexible tape member and being dispersed into the underlying materials. A pattern which does not absorb the bleed-through material is printed on the underside of the flexible tape member. The underside of the flexible tape member also has disposed on it a frangible layer of material that does not adhere to the pattern printed on the underside of the flexible tape member. An adhesive layer is disposed over the frangible layer.Type: GrantFiled: July 22, 1999Date of Patent: July 2, 2002Assignee: Consolidated Graphic Materials Inc.Inventor: Erik Hoffer

Publication number: 20020076552Abstract: The present invention is a self-wound thermal transferable over-laminating (OL) tape, preferably for receiving a thermal transfer image from a thermal transfer ink ribbon and preferably using pressure-sensitive-adhesive (PSA). The preferred embodiment of the OL PSA tape comprises a layer of plastic film with two opposing sides. The first opposing side of the plastic film contacts a printable release coating comprising clear polyamide-carbamate receptive to wax-type, resin-type and wax-resin hybrid thermal transfer inks. The second opposing side of the plastic film contacts a pressure-sensitive-adhesive. The pressure sensitive adhesive is, preferably, acrylic adhesive.Type: ApplicationFiled: December 20, 2000Publication date: June 20, 2002Inventor: Tong Chee Hsu

Patent number: 6403190Abstract: A release liner for use with face stocks for pressure sensitive labels, tapes, decals and other products formed from sheet and roll stock. A filled polymer is laminated to one side of a paper web. An extrudate is laminated to the other side of the paper substrate to form a release liner. The filled polymer has paper-like properties and replaces paper tissue back liners.Type: GrantFiled: March 30, 2000Date of Patent: June 11, 2002Assignee: FLEXcon Company, Inc.Inventors: James M. Casey, David A. Kitch, John M. Becker

Patent number: 6395360Abstract: Provided is a release liner formed of a plastic film having a laminated structure of at least three layers, described specifically, as two surface layers, (A) a release functioning layer composed of a polyethylene film having a density of 0.88 to 0.92 g/cm3 and a melt index not greater than 10 g/10 minutes and (B) a surface film layer having a thermal linear expansion coefficient similar to that of said release functioning layer and, as an intermediate layer, (C) a reinforcement layer having a melting point not less than 120° C. By forming a pressure-sensitive adhesive layer on the surface of the release functioning layer (A) of the above-described release liner, a pressure-sensitive adhesive sheet can be obtained. The release liner exhibits good release function without using a silicone-base releasing agent and has heat resistance sufficient for not causing deformation such as curl even when heat is applied to the liner.Type: GrantFiled: December 23, 1999Date of Patent: May 28, 2002Assignee: Nitto Denko CorporationInventors: Hitoshi Takahira, Hiroshi Yamamoto, Naoyuki Nishiyama, Masahiro Ohura
