These 20 x 12 x 4 inch single wall corrugated boxes are built specifically for flat and low-profile products that require a shallow interior depth without sacrificing structural integrity. Manufactured from ECT-32 kraft corrugated board, each carton delivers reliable stacking strength and puncture resistance through standard parcel handling conditions.
The interior footprint suits a broad set of outbound shipping needs: framed artwork, apparel, documents, promotional materials, automotive trim components, and packaged goods moving through e-commerce fulfillment or retail distribution. The shallow profile reduces void fill requirements and helps keep dimensional weight low on parcel shipments.
Boxes ship flat, minimizing warehouse storage footprint until needed. Each bundle contains 25 boxes. The ECT-32 rating confirms these boxes meet standard compression and edge-crush performance requirements for single wall corrugated construction.
