Patent number: 7534300Abstract: A method of designing and the resulting thermally stable heated coating die apparatus, the die apparatus including a die having a die geometry and a heating system with heaters and temperature sensors. The method and resultant apparatus provides minimized temperature gradients, flat die lip faces in a die to roll plane and a flat die in a plane perpendicular to die flat lip faces and parallel to substrate width. The method optimizes simultaneously: die geometry, placement of the heaters, placement of temperature sensors, and shielding from operating conditions, using heat transfer and structural numerical modeling and statistical analysis while considering die functionality characteristics, minimum increment of temperature measurement and control accuracy related to minimum acceptable deviation from flatness, coating die material of construction relative to thermo-structural material properties, and desirable coating die material properties.Type: GrantFiled: October 31, 2007Date of Patent: May 19, 2009Assignee: Avery Dennison CorporationInventors: Mark James Wyatt, Erik Martin Pedersen, Luigi Sartor

Patent number: 6547887Abstract: Multilayer PSA label constructions that achieve a good balance of properties, namely, adhesive performance, convertibility, and laser printer performance, and, optionally, good wet-out on plastic substrates and low haze. The multilayer PSA construction comprising a facestock, a multilayer adhesive coating, and a release liner. The adhesive coating is made of a face side adhesive (FSA) layer comprising a first emulsion acrylic PSA, which is in contact with the inner surface of the facestock, and a liner side adhesive (LSA) layer, comprising a second emulsion acrylic PSA different from the first acrylic PSA, which is in contact with the FSA. The adhesive coating has a coat weight of less than about 26 g/m2 and a flow of less than about 50 &mgr;m at room temperature. The construction exhibits a loop tack value of at least about 3.5 N/25 mm at 5° C. on a polyethylene substrate.Type: GrantFiled: December 15, 1999Date of Patent: April 15, 2003Assignee: Avery Dennison CorporationInventors: Chan U.

Patent number: 5993961Abstract: A multilayer adhesive construction and method for production of said construction are provided. The construction comprises a facestock, a barrier layer on the facestock, and an adhesive layer on the barrier layer. The barrier layer comprises a pressure-sensitive adhesive which inhibits the migration of mobile species such as oils, resins, tackifiers, or plasticizers from the adhesive layer into the facestock or from the facestock into the adhesive layer. This migration of mobile ingredients often manifests itself as swelling or hardening of the facestock which, in turn, leads to wrinkling of the adhesive construction and general loss of adhesion. The multilayer adhesive construction of the invention thus improves adhesion and the appearance of the label by inhibiting wrinkling and/or staining.Type: GrantFiled: June 7, 1995Date of Patent: November 30, 1999Assignee: Avery Dennison CorporationInventors: Ronald Ugolick, T. Liem Ang, Luigi Sartor

Patent number: 5962075Abstract: A method for simultaneously coating multiple thin layers of relatively viscous fluids comprises the relative adjustment of the viscosity of the fluids in order to achieve a viscosity ratio in the optimum range without adversely affecting the adhesive properties of the fluids. In the preferrred method, viscosity is adjusted by varying the temperature of one or both fluids prior to coating and/or by reformulating the liquids to vary their relative viscosities.Type: GrantFiled: March 15, 1996Date of Patent: October 5, 1999Assignee: Avery DennisonInventors: Luigi Sartor, Stephen C. Huff, Craig N. Kishi, Daniel Meyer, Jesse C. Ercillo

Patent number: 5925432Abstract: Disclosed herein is a primerless removable pressure sensitive adhesive construction comprising an unprimed facestock, a first adhesive layer in contact with the facestock, a second removable pressure sensitive adhesive layer in contact with the first adhesive layer, and a release surface in contact with the second adhesive layer. Advantageously, constructions of this design exhibit improved layflatness in comparison to conventional emulsion primed removable pressure sensitive adhesive constructions.Type: GrantFiled: March 15, 1996Date of Patent: July 20, 1999Assignee: Avery Dennison CorporationInventors: Kamram Kian, Henk de Koning, Yukihiko Sasaki, Luigi Sartor
