30 x 4 x 4 in Literature Mailer

This Zoro Select M3044 mailer is a reinforced single-wall corrugate box designed for shipping documents, catalogues and flat literature. The white exterior presents a clean, professional appearance for business correspondence. Each unit measures 30 inches long by 4 inches wide by 4 inches high inside, accommodating long-form printed materials. The pack contains 50 mailers for high-volume fulfilment operations.

B-flute construction with 200# board test

The B-flute profile and 200-pound board test give the mailer rigid edge protection while keeping the wall thickness to 1/8 inch. Single-wall construction resists crushing during transit without the bulk of double-wall alternatives. Corrugate material is 100 percent post-consumer recyclable, meeting ASTM-D-5200 standards for recycling compatibility. Flat storage and quick assembly keep packing lines moving.

Replaces padded envelopes for rigid items

Shippers sending photographs, certificates or bound reports that must not bend will find this mailer a direct upgrade from flexible mailers. The fixed 30-inch length suits standard portfolio and blueprint sizes but will not fit oversized posters or rolled plans. Buyers needing variable depths or heavier-duty double-wall strength should select a different container.

Questions about this item

How do I fold the B-flute corrugate walls without cracking the 1/8 in board?

Score along the pre-creased lines first, then fold the single-wall panels inward; forcing the 200# board before scoring splits the flute.

Will the 100% post-consumer white corrugate yellow or weaken if stored long-term?

The material meets ASTM-D-5200 and resists normal ageing; keep the flat pack dry and away from direct sun to preserve strength.

At what load does the 200# single-wall construction start to bow under a full 30 in length?

The 200# board test rating marks the limit; sustained weight beyond that causes the 30x4x4 in mailer to deflect permanently.
