Patents by Inventor Steven B. Garland

Steven B. Garland has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cross-linked multilayer heat-shrinkable oriented polymeric film
    Patent number: 5089352
    Abstract: Described is the presence of both a chemical cross linking agent and irradiation such as electron beam irradiation, in the manufacturing process for making an oriented, i.e. heat-shrinkable, polymeric film. The presence of both results in an amount of cross-linking that is effective to accomplish an increased orientation rate during manufacturing.
    Type: Grant
    Filed: December 18, 1990
    Date of Patent: February 18, 1992
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: Steven B. Garland, Thomas C. Warren
  • High shrink energy/high modulus thermoplastic multi-layer packaging film and bags made therefrom
    Patent number: 5079051
    Abstract: Disclosed is an oriented, heat-shrinkable, packaging film having a layer of polyamide or polyester. The film has a high shrink energy and high modulus.
    Type: Grant
    Filed: December 8, 1989
    Date of Patent: January 7, 1992
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: Steven B. Garland, Donald J. d'Entremont
  • Bonding method effecting inter-ply adhesion between saran and linear ethylene copolymers
    Patent number: 4909881
    Abstract: This invention relates to a method of improving the adhesion between a layer of vinylidene chloride copolymer and a layer of a linear ethylene/alpha-olefin copolymer and to the film produced thereby. More particularly, the invention relates to heat shrinkable films having a barrier layer of vinylidene chloride copolymer and a layer of linear low density polyethylene or very low density polyethylene and to a method for increasing the adhesion between the layers and thereby decreasing the incidence of delamination by blending the linear ethylene/alpha-olefin copolymer with an ethylene/butyl-acrylate copolymer.

  • Inter-ply adhesion between saran and linear ethylene copolymers
    Patent number: 4842952
    Abstract: A multilayer film is disclosed having improved adhesion between layers and consisting essentially of the following elements:(a) a layer consisting essentially of vinylidene chloride copolymer; and,(b) a layer consisting essentially of about 5-40 weight percent of ethylene/butyl-acrylate copolymer having a melting point of about 110.degree. C. blended with about 95-60 weight percent of linear ethylene/alpha-olefin copolymer.
    Type: Grant
    Filed: March 31, 1988
    Date of Patent: June 27, 1989
    Assignee: W. R. Grace & Co.-Conn.
    Inventor: Steven B. Garland
  • Process for enhanced orientation of polymeric films
    Patent number: 4797235
    Abstract: Described is the presence of both a chemical cross-linking agent and irradiation such as electron beam irradiation, in the manufacturing process for making an oriented, i.e. heat-shrinkable, polymeric film. The presence of both results in an amount of cross-linking that is effective to accomplish an increased orientation rate during manufacturing.

  • Inter-ply adhesion between saran and linear ethylene copolymers
    Patent number: 4778715
    Abstract: Disclosed are multi-layer films having improved adhesion between layers. A film layer comprising vinylidene chloride copolymer is directly adhered to a film layer comprising a blend of ethylene/butyl-acrylate copolymer with linear ethylene/alpha-olefin copolymer.
    Type: Grant

  • Inter-ply adhesion between saran and linear ethylene copolymers
    Patent number: 4755436
    Abstract: A multi-layer film is disclosed having improved adhesion between layers and consisting essentially of the following elements:(a) a layer consisting essentially of vinylidene chloride copolymer; and,(b) a layer consisting essentially of about 5-40 wt. % of ethylene/butyl-acrylate copolymer having a melting point of about 110.degree. C. blended with about 95-60 wt. % of linear ethylene/alpha-olefin copolymer.
