Structures Of Polymers Made From Single Site Catalysts

US Patent:
6511568, Jan 28, 2003
Filed:
Oct 6, 2000
Appl. No.:
09/684567
Inventors:
John P. Eckstein - Neenah WI
Johnny Q. Zheng - Peach Tree City GA
Mark E. Nordness - Menomonee Falls WI
Keith D. Lind - Appleton WI
George H. Walbrun - Menasha WI
Gregory K. Jones - Cincinnati OH
Gregory J. Seeke - Neenah WI
Ronald J. Dembowski - Bethlehem PA
Douglas J. Jackson - Wayne NJ
Assignee:
Pechiney Plastic Packaging, Inc. - Chicago IL
International Classification:
B32B 304
US Classification:
156216, 428 357, 222107, 220837
Abstract:
Copolymers of ethylene and alpha olefins that have been formed by the polymerization reaction in the presence of a single site catalyst, such as a metallocene, are used to form collapsible dispensing containers and/or components thereof. Blends of the copolymers with propylene polymers are disclosed and used to form a body wall layer or a collapsible dispensing container head having good bond strength with a body wall layer formed of an ethylene polymer. Methods for improving the adhesion between collapsible dispensing container components, such as between body wall layer formed of an ethylene polymer and another body wall layer formed of a propylene polymer, or between a body wall layer formed of an ethylene polymer and a collapsible dispensing container head formed of a propylene polymer, are also disclosed.
