Partners Brand MLR1293 Corrugated Mailers

White corrugated mailers measuring 12 by 9 by 3 inches arrive in a 50-count bundle for high-volume shipping operations. The rigid flute construction protects contents during transit while the light exterior keeps weight-based costs low.

Replaces loose boxes and padded envelopes

Switching to these self-sealing mailers eliminates the need for separate tape, void fill and box assembly time. The jump pays off when daily order volume makes manual packing a bottleneck.

Suits e-commerce sellers shipping books.

Businesses needing custom branding, heavier-duty double-wall construction or sizes outside the fixed 12 by 9 by 3 inch format should evaluate alternative packaging lines.

Questions about this item

What internal dimensions does the 12x9x3 mailer provide for product fit?

The mailer measures 12 inches long, 9 inches wide and 3 inches deep, giving a 12 x 9 x 3 inch cavity for contents.

How do you seal the corrugated mailer, and what step is often missed?

Fold the scored flaps, then apply pressure-sensitive tape across the centre seam; skipping the tape leaves the package open in transit.

When should the mailers be replaced if stored long-term?

Replace any bundle that shows crushed flutes, moisture stains or loss of rigidity, as damaged corrugate no longer protects contents.
