Supply Air 6x4x3 Corrugated Cardboard Shipping Boxes – White Mailer Boxes for Packing, Moving & Storage (Multiple Pack Sizes)

Highlights

• CORRUGATED CONSTRUCTION: Each box is constructed from single-wall corrugated cardboard with 32 ECT (Edge Crush Test) rating, consisting of a fluted medium layer between two kraft linerboard sheets that create a rigid structure for absorbing impacts during shipping and handling
• DIMENSIONS: Interior dimensions measure 6 inches length × 4 inches width × 3 inches height; boxes ship flat (knocked down) with scored fold lines for assembly; accommodates items up to 6 x 4 x 3 inches
• MATERIAL: White kraft corrugated cardboard exterior accepts ink, adhesive labels, stamps, and direct printing; the uncoated surface creates friction that prevents shifting during stacking and transit
• WEIGHT: Each individual box weighs approximately 0.11 pounds; the corrugated structure reduces the per-unit weight while maintaining structural integrity under compression
• CLOSURE: Boxes feature interlocking top flaps that fold along scored lines; the flap design allows closure without adhesive for assembly, though sealing tape is recommended to secure contents during shipment
