Side-loading cardboard boxes are ideal for packing items like mirrors, picture frames, artwork, and other flat products. The strong side-loading design is easy for packing and feature full overlapping flaps for more stability strength and security. Boxes shaped this way can save on storage space and shipping. Choose from different sizes that will fit any product you want to pack and be assured that your valuables will stay in one piece during transport. All our side-loading boxes are made from corrugated cartons that are 100% recyclable and available in different sizes and shapes.
