What Are Half-Slotted Containers?

Half-slotted containers are corrugated boxes with flaps on just one end, leaving the top open for easy access. This structure is perfect for applications where quick loading and unloading is essential. Pair them with a custom lid or telescoping cover to add protection and security during transit or storage.

Our corrugated HSC boxes come in a wide variety of strengths, flute types, and board grades, so you can choose the ideal option based on your product weight, shipping conditions, and storage environment.
