  • Aldehyde scavenging compositions and methods relating thereto
    Patent number: 5413827
    Abstract: The present invention relates generally to packaging materials which enhance food freshness, particularly for foods having a high fat content. The packaging materials of the present invention comprise an aldehyde scavenger, such as, polyethylene imine, and optionally, an oxygen scavenger.
    Type: Grant
    Filed: January 3, 1994
    Date of Patent: May 9, 1995
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Vincent Brodie, III, Donna L. Visioli
  • Aldehyde scavenging compositions and methods relating thereto
    Patent number: 5362784
    Abstract: The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyester polymer(s) (including copolymers and derivatives thereof); such compositions can be used in producing films or devices which are capable of scavenging unwanted aldehydes. More specifically, the preferred compositions of the present invention comprise a PAI substantially discontinuous phase and a polyester or copolyester substantially continuous phase in a weight ratio of PAI to polyester polymer of about 0.001-30:100 which optionally also includes a binding agent.
    Type: Grant
    Filed: May 28, 1993
    Date of Patent: November 8, 1994
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Vincent Brodie, III, Donna L. Visioli
  • Method for reducing odors in recycled plastics and compositions relating thereto
    Patent number: 5350788
    Abstract: The present invention relates generally to recycled plastics which exhibit noxious odors. More specifically, the present invention is directed to a method of reducing unwanted odors in such recycled plastics by incorporating a polyalkylene imine ("PAI"), more preferably polyethylene imine ("PEI").
    Type: Grant
    Filed: March 11, 1993
    Date of Patent: September 27, 1994
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Donna L. Visioli, Vincent Brodie, III
  • Aldehyde scavenging compositions and methods relating thereto
    Patent number: 5284892
    Abstract: The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyolefin polymer (including copolymers and derivatives thereof); such compositions can be used in producing packaging films for oil containing foods, whereby the film is capable of scavenging unwanted aldehydes from the food product. The preferred compositions comprise a PAI substantially discontinuous phase and a olefinic polymer (including copolymers or derivatives thereof) substantially continuous phase in a weight ratio of PAI to olefinic polymer of about 0.001-30:100 which optionally also includes a binding agent.
    Type: Grant
    Filed: November 10, 1992
    Date of Patent: February 8, 1994
    Assignee: E. I. Du Pont de Nemours and Company
