Custom Printed Mailer Boxes for E-Commerce

Mailer boxes fold into a self-locking corrugated carton built for the journey to your customer. The construction assembles quickly at the packing bench and closes without loose lids or extra parts, which keeps despatch efficient for online shops, retail orders and subscription runs. Because the box is made to your own dimensions, the product sits with less movement and the parcel arrives looking considered rather than improvised.

Printing and internal fit

Corrugated cardboard gives the box a sturdy structure for a wide range of products, and the printable surfaces let you carry your branding through to the doorstep. Print can be applied to the exterior, the interior or both, so the box works as packaging and as part of the unboxing. For heavier or more fragile items, an insert can keep the contents positioned securely inside the box during transit.

Options to specify include:

  • Custom sizes matched to your products
  • Full-colour CMYK or Pantone printing
  • Interior and exterior print, with matte or gloss finishes
  • Inserts or dividers to hold contents in place

Made in corrugated cardboard to your custom size from a minimum of 100 boxes, mailer boxes suit clothing, cosmetics, accessories and recurring subscription products. Share your size, quantity, artwork and finish so the fit and print can be matched to your brief.
