White Corrugated Literature Mailer

These white corrugated mailers ship documents, catalogues and small flat items in a rigid single-wall box. The B-flute construction and ECT-32 rating give a 65 lb maximum load capacity for secure transit. Each pack contains 50 mailers ready for immediate use.

Build and Daily Use

The mailers measure 4 3/8 in by 4 3/8 in by 3 1/2 in inside and out with a 3/16 in wall thickness for consistent stacking. White exterior surfaces accept labels, stamps and handwritten addresses without show-through. Flat-packed delivery saves shelf space until the next mailing run.

Upgrade Context

They replace flimsy padded envelopes when contents need crush resistance and a defined rectangular shape. The 100 percent post-consumer recyclable cardboard suits offices with sustainability targets. Buyers who need larger internal dimensions or heavier-duty double-wall construction should look elsewhere.

Questions about this item

What does the ECT-32-B rating mean for stacking strength?

ECT-32-B indicates the mailer meets a 32 lb edge crush test with B-flute construction, supporting up to 65 lb maximum load capacity per unit.

How much shelf depth is needed for a 50-pack of these mailers?

Each mailer measures 4 3/8 in outside length and width with 3/16 in wall thickness, so a 50-pack stack requires roughly 9 3/4 in of depth.

Do these mailers arrive flat, and how are they assembled?

They ship flat and fold into shape; the common mistake is not fully seating the tuck flaps into the locking slots, which reduces crush resistance.
