Mailer Boxes

SELECTION EXPERT ADVICE

Self-Locking vs Tape-Seal Mailer Formats
MORE INFO
Self-locking mailer boxes close without tape using interlocking tabs, which speeds up packing on high-volume lines and creates a cleaner, more professional appearance. Tape-sealed formats allow more flexibility in fill height and can handle slightly oversized contents that exceed the box depth without a visible gap at the closure.
Size Selection for Common Product Categories
MORE INFO
Literature mailers suit flat, rigid items like books, catalogs, and framed prints. Garment mailers handle folded clothing and accessories efficiently. Multimedia mailers are sized for CDs, DVDs, and gaming cartridges. Choosing the right format for your specific product eliminates wasted space and reduces the cushioning material needed to fill the gap.
Mailer Boxes for Branded DTC Packaging
MORE INFO
Branded mailer boxes with consistent dimensions create a repeatable unboxing experience that can be photographed, shared, and recognized as part of your brand identity. Standardizing on one or two mailer sizes across your product line simplifies procurement, reduces pack station training time, and lowers your per-unit packaging cost.
