These 20 x 20 x 4 inch white deluxe literature mailers are built from ECT-32-B single wall corrugated board and engineered for tool-free assembly. The front locking tab closure and reinforcing side flaps secure contents without tape, glue, or staples — reducing pack time and consumable costs in high-volume shipping environments.
The clean white exterior suits retail distribution, direct mail campaigns, and branded fulfillment operations. Publishers, print distributors, trade show suppliers, and manufacturers rely on these mailers for large-format catalogs, sample boards, signage flats, architectural drawings, and folded print materials that must arrive undamaged and presentation-ready.
Side flaps contribute stacking rigidity for palletized storage and multi-unit shipments. Each bundle contains 25 mailers and ships via parcel carrier.
