Pack Kontrol® 200 lbs / ECT 32 Corrugated boxes are a staple of the packaging world, and your number one choice for safely delivering products to your customers. Available in multiple sizes, shapes, and wall thicknesses, they can accommodate almost any kind of object. Corrugated boxes also come in box styles that offer unexpected uses and functionalities, like shipping artwork or reducing the need for packing tape. They’re strong, sturdy, and reliable, handling jobs other shipping containers can’t. When a mailer won’t do, a box certainly will. All corrugated boxes ship and store flat to save space.
