A tuck top mailer is a corrugated shipping box with a hinged lid that folds over and tucks into a slot in the front panel. The Best Price Boxes prints them custom, inside and out, with no minimum order, and we match or beat a written quote for the same specs.
How the tuck top closes and why it matters
The lid is part of the same sheet as the base, so there is no glue on the hinge and nothing to peel. You fold the lid down, push the tuck tab into the front slot, and it holds by friction. For a parcel that leaves your warehouse and arrives in a stranger’s hands, that is usually enough for soft or light contents. If the contents are heavy or the route is rough, add a strip of tape or a branded sticker across the seam. The tuck holds the lid shut, but it is not a lock, and honesty here saves refunds.
Mailers also fold flat for storage, which matters if you run a small stockroom. A pallet of flat tuck top mailers holds far more units than the same quantity built as rigid boxes.
Sizing for what goes inside
Measure the packed item, not the bare product. If you wrap clothing in tissue or put a bottle in a sleeve, measure after that step. Add about a quarter of an inch to each dimension for corrugated, which is thicker than paperboard and eats into the inside space. Mailers are quoted by inside length, width and depth. If the contents can shift, order a paperboard or custom foam insert to hold them in place, because a loose product is what breaks in transit, not a weak box.
Flute, board and print
Most mailers use E-flute corrugated, which is thin enough to print cleanly and stiff enough for light parcels. B-flute is thicker, a better pick for heavier items, but the print surface is slightly rougher. Kraft exterior with a one or two colour print is the most economical look. White-faced board takes full CMYK and Pantone colour, and an inside print turns the unboxing into part of the brand. Matte or gloss aqueous coating is common. Anything fancier, such as foil, is better saved for rigid boxes.

Tuck top versus other mailers
A tuck top mailer is a good all-rounder, but it is not the only style. If you want a stronger lid lock for heavier orders, look through our wider mailer boxes collection and ask about a different closure. A folding carton with a similar lid, our tuck top boxes, is paperboard and suits retail shelves, not parcel shipping. Pick the mailer for anything that travels with a carrier, and the paperboard carton for anything that sits on a shelf.
One practical note on artwork: the fold lines and the tuck slot cut across the print, so keep logos and key text away from the hinge and the slot. We lay your artwork over the dieline and flag any clash before anything goes to press, which avoids a logo split across the lid edge.
Send the inside dimensions, or the product dimensions and we will work them out, plus the quantity, even if it is one. We draw the dieline and quote it. With no minimum order, ordering a single printed sample first is a sensible way to test fit and print colour before committing to a bigger run.
Frequently asked questions
What is a tuck top mailer box?
It is a one-piece corrugated shipping box whose lid folds over and tucks into a slot in the front panel. It ships flat, assembles by hand in seconds and closes without glue or tape. It is popular for ecommerce orders, subscription parcels and branded gift shipments.
Do you have a minimum order for tuck top mailer boxes?
No. There is no minimum order, so you can order a single printed sample or thousands for production. Send the inside dimensions and quantity, even if it is one, and we draw the dieline and quote it. The price-beat guarantee applies when you hold a written quote for the same specs.
Do tuck top mailers need tape to ship?
For light, soft contents, the tuck usually holds. For heavier items or rough routes, add a strip of tape or a branded sticker across the seam, because a tuck closure holds by friction and is not a lock. A sticker also doubles as a tamper indicator for the customer.
Which flute should I choose, E or B?
E-flute is thin and prints cleanly, so it suits light to medium parcels and branded unboxing. B-flute is thicker and gives more cushioning for heavier items, though the print surface is a little rougher. If you are unsure, send the product weight and we suggest one.
Can I print the inside of a tuck top mailer?
Yes. Inside print is one of the best uses of a mailer, because the customer sees it the moment they open the lid. White-faced corrugated takes full CMYK or Pantone on both sides. Kraft works well with a one or two colour design.
How do I measure for a tuck top mailer?
Measure the product after it is wrapped or sleeved, then add about a quarter of an inch to each dimension to allow for corrugated thickness and easy loading. Mailers are specified by inside length, width and depth. If you send the product size, we can calculate the rest.
