Title: Gas-permeable film and method for producing the same
Inventor: NAKAJIMA YOJI
IPC: C08L101/00
Filed: 2004-12-07
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate difficulties such as stretch breaking and nonuniform stretch caused during stretch processing for obtaining a gas-permeable film and to further provide a method with which standardized communicating through-holes are regularly produced.  <P>SOLUTION: A composition composed of a particulate soluble material having about several tens of μm is mixed in a polymer resin film when the polymer resin film is produced. When a crazing treatment or a stretch treatment, etc., of the polymer resin film are carried out, shearing of fibrils is gradually conducted in a part of the mixed particles. Thereby, communicating fine spaces are readily produced. The volume of a permeated gas in a constant pressure state can easily be regulated by specifying the size of the particles when the composition composed of the soluble material is mixed in the film.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
