The Landsberg P40 is a heavy-duty Regular Slotted Container (RSC) corrugated shipping box measuring 24" x 18" x 16" (length x width x height). Manufactured by Landsberg Orora, a leading packaging supplier, this box features a 44 ECT (Edge Crush Test) board rating, also known as 275-pound burst strength, making it significantly stronger than standard 32 ECT / 200-pound boxes commonly used for general shipping.

The RSC style means all flaps are equal in length and meet at the center when folded, providing a clean, secure closure on both top and bottom. The 44 ECT rating is designed for heavier or denser contents, better stacking strength, and more demanding shipping and storage conditions. This single-wall corrugated construction in natural kraft brown is suitable for moving, storage, and commercial shipping applications.
