The right box material will depend on what you are shipping nationally or internationally. Single wall corrugated box – the most common corrugated cardboard boxes. Ideal for light or small shipments, such as books and clothing. Double or triple wall corrugated box – thicker and stronger corrugated boxes, ideal for providing extra protectionUline and UPS recommend 200 lb. test boxes, which provide more strength and protection than 32 ECT boxes – a budget-friendly alternative for lightweight shipments. Uline 200 lb. test boxes are made with heavier paper and have 50% greater bursting strength than 32 ECT boxes. Greater bursting strength means fewer crushed and damaged boxes
Corrugated paper is a material consisting of a fluted corrugated sheet and one or two flat liner boards. It is made on "flute lamination machines" or "corrugators" and is used in the manufacture of shipping boxes. The corrugated medium and liner board both are made of kraft board, a paperboard material usually over 0.01 inches (0.25 mm) thick.
