Patent number: 6579611Abstract: A resin film for use in laminating for producing decorative laminates which is equal or superior to conventional polyvinyl chloride resins in suitability for embossing, processability, and long-term water resistance and can be significantly well-designed; and a decorative laminate in which the resin film has been laminated. The resin film is obtained by compounding a polyester resin with 0.5 to 60 wt. % crystallization accelerator having a particle diameter of 0.01 to 5 &mgr;m, forming the mixture into an unstretched film, and embossing at least one side of the film. The resin film is laminated to a metallic or wooden plate, a board, etc. to produce a decorative laminate.Type: GrantFiled: June 1, 2001Date of Patent: June 17, 2003Assignee: Toyo Kohan Co., Ltd.Inventors: Hiroyuki Iwashita, Koji Taguma, Yoshiyuki Sugimoto

Patent number: 6524667Abstract: A biodegradable, compostable, liquid-impermeable lined paper bag for containing wet wastes. All adhesives used in the process are cold glues applied without using heat, through an extrusion and/or metering application means. Cellulose film is used for the paper liner and dot matrix configuration of adhesive is applied between the cellulose and paper layers for lamination. The matrix-defined size of spacings between the points of application of adhesive on the cellulose film are preselected to permit passage of water vapour and oxygen through the cellulose-laminated paper and reduce stress points on the cellulose film. A second cold glue is applied to the bag bottom section by a matrix of extrusion adhesive guns via a programmable controller to predetermined areas of the bag bottom section.Type: GrantFiled: May 17, 2000Date of Patent: February 25, 2003Assignee: Prescott Paper Products (USA), Inc.Inventor: George P.
