81BYV0 is a plain 22" x 22" x 12" heavy-duty corrugated box with a double wall (275#/ECT-48). The double wall provides superior protection and strength allowing for the box to have good stacking ability compared to standard cartons. These kraft boxes are great for shipping and storing a wide range of materials and can also be used for retail display. These boxes are sold 10/bundle and ships and stores flat.

Key Benefits:
  • 200 lbs. - 275# (Bursting Test, lbs. per sq. in.) Measures the bursting strength. How much pressure is required to rupture the wall.
  • 48 lbs. - ECT-48 (Edge Crust Test, lbs. per in. width) - Measures the stacking strength. How much top to bottom pressure a box can withstand before crushing.
  • Cartons are sold in bundle quantities and ship flat to save on storage space and shipping.
Box Strength
The Mullen Busting Test measures the bursting strength of the corrugated linerboard while the Edge Crush Test measures linerboard stacking strength. For example, the 200 lbs. Mullen box and the 32 ECT box are comparable in stacking strength. But that is where the similarity ends. The Mullen Test box is better suited for the protection of heavier contents while the Edge Crush Test box provides lighter weight cartons with good stacking characteristics. When in doubt as to which box to use, always select the Mullen Test box because the construction of the linerboard cannot be altered. For example, 200# Mullen Test linerboard must be made of 42# per square inch basis weight paper and the medium or flute paper cannot be less than 23# per square inch basis weight.

Box MeasurmentsBox Measurements
Box measurements are always expressed in three dimensions (Length x Width x Depth) and always in that specific sequence. The length and width are the opening dimensions of the box, and the length is always the larger of the two (unless they are equal). The depth is how far you can reach into the box, and is the distance measured perpendicular to the length and width. These measurements always relate to the inside dimensions of the box. When measuring your box always leave space on all sides and above and below product for cushioning, such as bubble cushioning or loose fill.
