US Patent:

20110171449, Jul 14, 2011

Filed:

Jan 11, 2011

Appl. No.:

13/004840

Inventors:

Mary Ruth LEHRTER - Cincinnati OH, US
Adam Pacelli - Brooklyn NY, US

International Classification:

B32B 3/26
B29C 44/12

US Classification:

428220, 264 453

Abstract:

A micro-voided film comprising high density polyethylene having a molecular weight of at least about 200,000, and low aspect ratio filler having a mean particle size from about 1 to about 25 microns. The film has a thickness of from about 10 to about 75 microns and a void fraction of from about 0.60 to about 0.75. The micro-voided film is made by a process comprising extruding the composition into a film having a thickness of from about 50 to about 300 microns, and orienting the extruded film using a high stalk, blown film process. The process produces a stabilized high stalk for increasing the production rate of blown, high molecular weight polyethylene, while increasing the film's physical and mechanical properties. The high stalk can be stabilized by application of high velocity, low volume flow rate of air over the interior and exterior surfaces of the extruded film.

Abstract:

A micro-voided film comprising high density polyethylene having a molecular weight of at least about 200,000, and low aspect ratio filler having a mean particle size from about 1 to about 25 microns. The film has a thickness of from about 0.1 to about 20 mils and a void fraction of from about 0.60 to about 0.75. The micro-voided film is made by a process comprising extruding the composition into a film having a thickness of from about 20 to about 200 mils, and orienting the extruded film using a high stalk, blown film process.
