The increased production of small arms am
munition has brought forward many new prob
lems in the packaging of these items, such as .30
caliber and .50-caliber cartridges. Many of the
cartridge cartons and containers now in use are
made in set-up form, which is a slow and costly
process and is often not adapted to large volume
requirements. From another standpoint, con
