Expansion Mailers
Questions, answered.
What does the expansion gusset do?
The gusset lets the mailer expand to hold depth, so bulkier or boxed goods fit without a separate box. Both 3-inch and 4-inch gussets are available across the sizes.
How many mailers come in a carton?
Expansion mailers ship 200 per carton. One carton is the minimum order, and the per-unit price shown is for a single carton.
Can I add my logo?
Yes. Any expansion mailer can be custom printed in single or two color, direct from our factory. Request a custom quote to get started.
Are they recyclable?
Every TerraBoard expansion mailer is 100% curbside recyclable and plastic-free, made with renewable kraft fibers. No plastic, foil, or synthetic coatings.
Do I get a discount for volume?
Yes. The per-unit price drops automatically as your carton count climbs, and high-volume orders route to a fast bulk quote.
