Correct Products supplies a broad selection of side-loading corrugated boxes and cartons. Kraft side loading boxes are ideal for large flat products such as frames and mirrors. Our side loading boxes feature a full overlap flap which provides extra durability, stacking strength and edge protection. Kraft corrugated side loading boxes are available in many stock sizes in both standard 200#ECT-32 and heavy duty 275#ECT-44. In addition, we supply white corrugated side loading boxes with self-seal closure. These boxes are similar to FedEx Express and UPS Air boxes, featuring an easy open tear strip at the top and peal and seal strip making closure a snap. Side load locking mailers offer another option for quick box closure making shipping and packing fast and easy. These boxes close with a locking tab, no tape or staples needed. All of our corrugated side-loading boxes are in stock for immediate shipment, sold in bundled quantities and ship flat to save on shipping and storage space.
