Abstract

The present invention provides compositions and methods addressing the problems and disadvantages associated with orienting articles prior to disposition in a housing. Compositions and methods of the present invention, in some embodiments, can provide articles with the proper orientation for disposition in a housing without the encumbrances associated with hand assembly, such as increased production time and increased potential for contamination. As a result, manufacturers and users of products comprising polymeric articles disposed in housings are no longer restricted to the use of articles having isotropic shapes and homogeneous properties.
