Common questions
Do these mailers require tape or glue to assemble?
No. These one-piece fold-and-tuck mailers assemble in seconds without tape, glue, or staples. Simply fold the side flaps and secure with the front outside tuck closure for a professional, finished appearance.
What makes ECT-32-B corrugated better for document shipping?
ECT-32-B (Edgewise Crush Test) corrugated provides crush resistance and puncture protection compared to lighter grades. This premium construction protects delicate documents and ensures they arrive in showroom-ready condition, which is critical for brand-conscious e-commerce brands.
How many pieces can I fit in an 18 x 12 x 6" mailer?
The 18" x 12" x 6" interior accommodates substantial volumes of folded documents, catalogs, brochures, and flat promotional materials. For specific volume questions, measure your product stack, most marketing collateral fits comfortably with room to add protective cushioning.
Are these mailers environmentally friendly?
Yes. These kraft deluxe literature mailers are made from recyclable corrugated kraft material, aligning with sustainable packaging practices and supporting your brand's environmental commitments.
