Easy-Fold Mailers for Shallow Items

These white mailers measure 12 by 11 1/2 by 3 inches and arrive in a 50-count bundle. They suit businesses sending flat or shallow goods such as documents, apparel or boxed accessories. The easy-fold design speeds packing without tape or glue.

Lightweight Construction Reduces Shipping Weight

Single-wall corrugated fibreboard keeps the parcel light so postage costs stay low. The rigid fluting resists crushing during normal conveyor sorting while adding minimal bulk. No special handling is required beyond standard carrier acceptance.

Self-Seal Flap Simplifies Fulfilment

An integrated adhesive strip closes the mailer securely once the contents are loaded. The 3-inch depth accommodates items up to that thickness without bulging. White exterior provides a clean surface for labels or branding stamps.

Questions about this item

How do I fold the 12 x 11 1/2 x 3 Easy-Fold Mailer correctly and what step do people skip?

Fold the side panels inward along the scored lines, then fold the bottom flap up and press the adhesive strip firmly; the step most often missed is peeling the liner off the self-seal strip before pressing.

What part of the 50-count bundle will need replacing first with regular use?

The self-seal adhesive on each mailer is single-use, so after one shipment you replace that mailer with a fresh one from the bundle.

At what point does the 3-inch depth limit how much I can ship in one mailer?

The 3-inch expansion gusset is the first constraint; contents thicker than that will prevent a secure seal.
