Custom Corrugated Mailer Box — Heavy-Duty E-commerce Shipper

When your products are heavy, bulky, or particularly vulnerable to crush damage, standard mailer boxes simply aren’t enough. Our heavy-duty custom corrugated mailer boxes are manufactured from B-flute, C-flute, or double-wall corrugated board — the same structural grades used by major logistics operators — and printed with your brand identity in full colour. From electronics to kitchen goods, tools to sporting equipment, these boxes are engineered to survive multiple courier handlings while arriving looking pristine.

Product Specifications

Materials Available

E-flute (thin, printable, lightweight), B-flute (standard corrugated, excellent rigidity), C-flute (maximum stacking strength), BC double-wall corrugated (industrial grade, heavy loads), and ECT-rated boards (Edge Crush Test certified for stack performance in automated warehouses).

Printing Methods

Flexographic printing (up to 6 colours, most cost-effective for corrugated), litho-laminate printing (photographic quality CMYK on corrugated), digital printing for short runs and prototypes, and UV-printed corrugated for the sharpest brand detail on heavy-duty board.

Surface Finishes & Special Effects

• Matte laminate on litho-laminated board — premium brand presence on heavy-duty shipper
• Gloss laminate — vivid product imagery on corrugated surface
• Aqueous coating — moisture resistance for cold-chain or outdoor logistics
• Varnish coat — fast-dry protective layer over flexographic print
• Partial print (exterior only) — cost-efficient brand presence on heavy-volume orders
• Full wrap print (inside + outside) — maximum brand impact even in the heaviest corrugated grades

Interior Insert Options

Die-cut corrugated dividers, foam block inserts, EPE foam wrap sheets, honeycomb cardboard pads, multi-cavity corrugated trays for multi-unit orders, and air pillow void fill — all available to complement the outer corrugated shipper and ensure zero movement in transit.
