Suspended filing pockets - of welded insulating thermoplastic film for moisture resistance and transparency

摘要

A series of filing pockets made from flexible thermoplastic film as undulations welded to be closed on three sides and opt. suspended from a horizontal bar. Pref. each pocket is slightly larger than the standard paper size to be accommodated and pref. the sheet for one side of the pocket has sufficient extra length to be folder back and welded to form a tunnel for a strip index label or a suspension rod. The pockets may have extra flaps which can be folded to close the mouth of the file. As an alternative to paper or cardboard for suspended filing systems, the thermoplastic file pockets are relatively tough and waterproof, and may be transparent to reveal the contents.
