Significance and Use4.1 Triple-wall corrugated fiberboard containers are used tounitize products into containers of size and shape suitable formanual or mechanical handling and to
18、protect the contentsagainst environmental, handling, shipping, and storage condi-tions.4.2 This practice is intended to cover some of the basicconstructions and styles of commercially available triple-wallfiberboard packaging used to unitize and protect contents.5.

This con
34、tainer shall beone piece of triple-wall corrugated fiberboard scored andslotted (slots shall have a minimum width of38 in. (10 mm) toform a body piece having four flaps for closing each of twoopposite faces. The flaps along the longer edge are the outerflaps, and those along the shorter edge are the
