Custom mailer boxes

A mailer box is the box people film themselves opening. It folds from one die cut piece of corrugated, locks closed with tuck flaps, and needs little or no tape. Print the outside, print the inside lid, add an insert, and the unboxing does half your marketing.

Built for the trip and the reveal

Most mailers use E flute corrugated: thin enough for crisp printing and neat folds, strong enough for courier networks. Heavier products can step up to B flute. The roll end tuck front style has double walls on the front and back, dust flaps to keep things clean and a lid that tucks in firmly.

Inside printing is the cheap thrill

Printing a message, pattern or thank you note inside the lid costs much less than people expect, and it is what customers remember. We can print a different colour inside and out, or keep the outside plain kraft with a full colour inside for a quiet exterior and a big reveal.

Plan sizes for the whole range

If you sell several products, a small family of mailer sizes keeps packing simple and gets you better pricing per size. Send us your product dimensions and we will suggest a set that covers most orders with little empty space.

Who orders these

Mailer Boxes: common questions

Do mailer boxes need tape?

Usually not for the top. The tuck flaps and ear locks hold the lid closed. Many brands add a sticker or a peel and seal strip for security and a tidy look.

Can mailer boxes go through the mail on their own?

Yes. E flute and B flute mailers are built to ship as is with Canada Post and couriers. Heavy or fragile products may need a stronger board or an insert.

Can you print the inside of a mailer box?

Yes, and it is one of the most popular upgrades. We will price inside printing next to outside only so you can compare.

What sizes do mailer boxes come in?

Any size you need. We make them to order around your product, so there is no stock size chart to squeeze into.
