Custom Mailer Boxes

Strong Mailing Boxes

Custom printed packaging sets a brand apart from the rest, it alludes to luxury, reliability and quality.  A brand that takes their message from the pages of a website to the hands of their customers is a brand that is well thought through and dedicated to creating an experience for their customers.

With an online audience who still do unboxing videos and influencers that wax lyrical about packaging it is important to add the finishing touches to any online order journey.

These box mailers are styled to be easy to open and close and then fold fully flat for recycling purposes (or reusing purposes if you can think of a fun design that allows them to avoid the landfill)

These mailers have a reliable three point closing system. The top flap folds over the main box and tucks securely into itself with an extra two side wings that add extra security as they tuck into the sides.

It's an excellent piece of origami that requires self assembly as they are provided flat packed for ease of storage. Simply fold as needed.

These mailers can be printed on the outside or the inside to add colour, fun, depth and branding to your customer's purchasing experience.

We love them as sample pack boxes, for cosmetics and care packages. They aren't food safe though so we would recommend you don’t use them for cupcakes or food packages.   

Assembly Guide

How to make your box

1. The product is delivered flat

2. We recommend creasing each fold before assembling the box

3. Fold up one of the box's side flaps

4. Slot the side flap into the hole on the base of the box

5. Repeat on the other side

6. The box is now ready to be filled. Close the lid, inserting the flaps into the slots created at the sides

How To Design Postal Parcel Boxes

Our Mailing boxes are printed on either a double-sided white E-flute Corrugated Board or a brown E-flute Corrugated Board. They are both FSC sourced, are single walled and 1.8mm thick. E-flute board is commonly used for mailers and product packaging due to the very fine flute, slimness and is great for print reproduction.                                              

Artwork Specification:

Please download the templates for your specific product to assist in setting up your artwork file. When submitting artwork, please send us two files: one with the template visible and overlaid on your artwork, and another with the template removed, displaying only your artwork. We use the first document to check your files are accurate and we will proof and print the second document.

Remember that the printed colours may change slightly due to the colour of the paper. White printing is not available on brown mailing boxes.

• Supply your print ready artwork in CMYK colour only.

• Include 10 mm of bleed on all sides, and that any full-bleed images cover the entire area surrounded by the bleed line

• Leave a minimum of 10 mm safe zone between text and the trim lines.                                               

• The final product may differ by up to 5mm from the original file submitted, please bear this tolerance in mind when creating your artwork.

• Artwork should be 300 dpi.

• To ensure best results, think about how the box will look when assembled, ensuring all images are orientated correctly.

• Supply your artwork in PDF/X1a format without crop marks
