The Overlap Slotted Container, commonly known as OSC, is designed with flaps of equal length where the outer flaps extend past each other, overlapping by at least one inch. This overlap not only adds structural integrity but also makes the box easier to secure using tape, adhesive, or industrial staples. The reinforced overlap provides additional cushioning at both the top and bottom, offering better protection for the contents inside. It also prevents the flaps from separating, ensuring a more secure and durable closure—ideal for shipping heavier or high-value items.
