Abstract
A plastic bag lined container is disclosed which includes four sides, a bottom and a top, with the container including a plastic bag liner loosely disposed therein which at least covers the container sidewalls. Incorporating a plastic liner in the container for discharge of elastic tapes or threads substantially reduces friction against the sidewalls during high speed discharge, while providing air pockets for even packing along the sidewalls, achieving uniform tension in the material during discharge to assure relatively precise elastic elongation in final products wherein the elastic tapes or threads are used.
