And more.

A mailer box is a one-piece folding box with a hinged lid and tuck-in front, often called a roll end tuck front (RETF) box. It is made from corrugated board, is strong enough to ship on its own, and opens neatly for a branded unboxing.
E-flute is about 1/16 inch thick and gives a smoother surface for sharp printing, so it suits most retail and subscription mailers. B-flute is about 1/8 inch thick and offers more crush resistance for heavier or bulky products.
Corrugated mailers have a fluted middle layer between two liners, which absorbs impact and resists crushing in transit. Paperboard mailers are a single solid sheet and are better for light items or as an inner presentation box.
Yes. Mailer boxes can be printed outside only, inside only or on both sides. Inside printing is popular for thank-you messages, social handles and patterns revealed when the customer opens the lid.
Measure the product's length, width and height and add space for inserts, tissue or padding. Internal dimensions are what matter, so share them with us and we will suggest the right size and flute.
Options include roll end tuck front, tuck top, ear lock, shoulder mailers, double-sided print mailers, literature mailers, vinyl record mailers, die-cut mailers and envelope mailers with clasp.
Yes. Corrugated, paperboard, foam and moulded pulp inserts can be added to hold products in place. Inserts are useful for fragile items like glass jars, cosmetics, electronics and PR kits.
Corrugated mailer boxes are widely recyclable and can be made from recycled kraft. Using water-based inks and skipping plastic lamination keeps the box curbside-recyclable.
Mailer boxes can have matte or gloss lamination, soft-touch coating, spot UV, gold or silver foil stamping, embossing and debossing. Foil and spot UV work best on E-flute because of its smooth surface.
Yes. Their sturdy build, full-surface printing and premium opening experience make them a popular choice for subscription brands, influencer PR kits and seasonal gift drops.
Yes. Corrugated mailers are made to handle courier and postal networks. For heavy or fragile items, B-flute or double-wall board with inserts gives extra protection on long routes.
Mailer boxes can carry packaged foods such as snacks, chocolates and baked goods. For direct food contact, a food-grade liner or coated inner board is recommended.
We accept print-ready AI, PDF, EPS and high-resolution PSD files. Artwork should be in CMYK at 300 dpi with fonts outlined, and our team can check files against your dieline.
Most mailer styles lock with tuck flaps and dust flaps, so no tape is needed for presentation. For shipping, a tear strip or a tamper-evident sticker can be added for extra security.
