Kraft Mailers

A kraft mailer planned for the shipment

Kraft mailers are foldable paper-led packages for products that need a contained outer wrap without the fixed walls of a rigid carton. The useful decision is how the mailer will be filled, closed, handled, and opened. Describe the packed item, its widest points, the number of pieces per mailer, and whether a sleeve, tissue, card, or small inner carton stays with the shipment. The natural kraft surface can remain visible behind a restrained print treatment, but the final material and construction must be confirmed against the product brief.

This format is flexible rather than a substitute for a crush-resistant box. A soft bundle, apparel item, stationery set, light accessory, or small retail pack may suit a mailer-style brief; a heavy object, sharp projection, or fragile item may need an additional inner pack or a more structured box. The standard fulfillment path starts at 50 units and production is from 7 business days after digital proof approval. Pricing stays quote-only because size, stock, closure, artwork, finish, and quantity change the specification.

What should be measured before sizing?

Measure the product as it will actually enter fulfillment: packed length, width, thickness, approximate weight, count per mailer, orientation, and the widest corners or projections. Include any retail carton, tissue, insert, sleeve, or protective wrap that remains inside. A folded garment should be described as a folded bundle; a card set should include its belly band; a boxed accessory should be measured in its carton. These details establish the usable interior and the space needed for the flap, seam, and closure.

The outside footprint is not the same as usable interior space. Fold allowances, seams, flap overlap, and the selected stock occupy part of the package, so the quote should be based on the finished packed arrangement rather than a generic nominal size. If two orientations are possible, state which face should greet the recipient and which side should carry the primary printed panel.

How does the closure affect the kraft format?

The closure determines the packing motion and the opening moment. A tuck-in flap can keep the mailer clean on the outside, while a peel-and-seal strip can support a quick packing line. A tear strip may define the recipient opening when the brief calls for it. Confirm whether the package is intended for one opening, a repeat-use route, or a separate overwrap; do not assume a resealable feature without a product-specific reason.

The flap must close over the filled item without pressing a hard corner into the fold or hiding required artwork. The digital proof is the right point to review flap overlap, side seams, score lines, opening direction, and any print that approaches a fold. If the packed contents change, the mailer should be rechecked rather than treated as the same size by default.

Use the kraft surface as part of the print brief

Kraft Paperboard, Corrugated Board, and SBS Paperboard are category material directions to compare with the packed weight, flexibility, fold pattern, and desired surface character. Uncoated kraft can keep visible fiber character and a low-glare appearance. A controlled one- or two-color treatment can let the brown tone participate in the palette, while broader coverage or a lighter panel may be reviewed when contrast matters. These are directions for specification, not promises about a fixed board weight or coating.

Artwork should map the front, back, side, and flap panels on the assembled mailer. The product images show an illustrative print layout. Production artwork must use the buyer approved brand and required information. Matte Lamination, Spot UV, Foil Stamping, and Embossing/Debossing can be considered for selected areas subject to artwork scale, fold placement, and material review.

Prepare a quote brief

Send the packed dimensions, product count, approximate weight, edge notes, preferred closure, material direction, artwork status, print coverage, finish request, quantity, and delivery destination. A photo or sketch of the packed arrangement helps the reviewer understand the opening and the panel that should face the customer. Explain whether the mailer must sit flat in a shipping carton, carry a return note, or show a message inside the flap.

Easy Box Packaging includes free US shipping and dieline and proof review on the standard fulfillment path. Quote requests are typically answered the same business day and always within 24 hours. A sample kit ships for a $44.99 USD charge credited toward the first order when you need to compare kraft surface character, fold behavior, closure feel, or print contrast in hand.

Confirm the assembled proof before production

Review the digital proof as an assembled package, not only as a flat artwork sheet. Check the packed fit, panel orientation, flap overlap, seam position, opening route, printed reading direction, and any finish near a fold. Confirm that the selected material direction and flexible profile agree with the item being shipped. The proof should also show where return information, handling notes, or a small interior message will sit after the mailer is closed.

A well-specified kraft mailer connects paper character, usable interior, closure, print panels, and the real fulfillment route. When the brief names those decisions clearly, the review can keep the package practical without assigning rigid-box performance to a flexible format.
