Tab Lock Mailer Boxes
Tab lock mailer boxes feature a tab and slot design that secures the top and bottom flaps without tape or glue. They ship flat, fold up fast, and stay closed through sorting and delivery. These boxes work well for shipping apparel, electronics, gifts, and household goods. Mailer Boxes Co stocks tab lock mailer boxes in standard sizes built from corrugated board that meets US carrier requirements. Use them for direct mail, e-commerce orders, or retail displays. Bulk quantities arrive quickly from our US locations, helping you keep packing operations running smoothly.
What Are Tab Lock Mailer Boxes
Tab lock mailer boxes have flaps with tabs that insert into slots for a tight seal. Insert the tabs, press down, and the box locks. This method prevents accidental openings and works without extra fasteners.
The design includes scored edges for clean folds and reinforced corners for stability. Boxes arrive knocked down flat, taking minimal shelf space. Once assembled, they form a six-sided enclosure ready for packing. Tab locking mailer boxes support weights up to 50 pounds in larger sizes, based on board strength.
