DOUBLE-WALL CARTON
When an extra-strong carton is needed, the double-wall box is recommended, especially for articles in glass of the half-gallon sizes. This box is of the same style as the regular slotted carton with the exception that the sides and flaps are double thickness, made of one sheet of double-face corrugated stock and one sheet of single-face corrugated board, glued together. In addition to being used for glass articles, the double-wall box is also used for large and heavy goods like mattresses, canned goods, etc.
