How it works

How to design a custom printed mailer

Bubble or honeycomb, the colour, and a stock size or your own.
2

Upload your logo

PNG, JPG or SVG. We warn you if it is too small to print sharp.
3

Add text & colour

Drag items around. The dashed line keeps them clear of the seals and the label space.
4

Check both sides

Turn the mailer over and open the flap. Save a mockup image to share.

We check your file and send a free PDF proof before anything is printed.

Mailer types

Mailers you can design

Every mailer has a peel-and-seal flap, so there is no tape to buy. Choose the outside that suits your brand.

Poly bubble mailer

Recycled poly film with a bubble lining. Light and water resistant. White, black, hot pink or rose pink, in gloss or matte.

Sizes

Stock sizes you can print

Sizes are the outside of the mailer, width × length, not counting the flap. The flap adds 40 mm, or 45 mm on mailers 330 mm long or more.

Need something else? Choose Custom size in the editor and enter any width from 90 to 600 mm and length from 120 to 650 mm.

The sealed side edges take a few millimetres each side, so the usable inside is a little narrower. We confirm the exact size on your proof.

Features

What you can do in the envelope editor

Stock sizes or your own

30 stock sizes across four mailer types, or a custom size in millimetres.

Front, back and flap

Design each side on its own: a logo on the front, a message on the back, a thank-you on the flap.

Full colour or one colour

Full colour for photos and gradients, or one ink: black, white, red, blue, green, teal or gold.

Logo pattern

Repeat your logo as an all-over pattern and set the spacing with a slider.

Shipping label space

Marks a 100 × 150 mm label area on the front and warns you if your design runs under it.

3D preview & mockup image

Turn the mailer over, open the flap, and save a mockup image to share with your team.

Print layout

Free mailer artwork templates

Switch the editor to Print layout to see your mailer flat, the way it goes on the press. It marks the cut edge, the flap fold, the side seals and the 3 mm bleed.

Keep logos and text 10 mm inside every edge: mailers are sealed along the sides after printing, and print can shift a few millimetres. Background colours can still run right to the edge. Prefer your own software? Download the template, add your artwork and send it with your quote request.

FAQs

Envelope editor FAQs

Can't find your answer? We're happy to help with sizes, films and printing.

02 8750 5347 info@ebpackaging.com.au

Is the envelope editor free?

Yes. The editor and the artwork templates are free to use, with no sign-up and nothing to install. You only pay if you go ahead and order printed mailers from us.

Are the sizes inside or outside measurements?

They are the outside of the mailer, width × length, not counting the flap. The sealed side edges take a few millimetres each side, so the usable inside is a little narrower. We confirm the exact size on your proof.

Why is there a border I can't print in?

Mailers are sealed along the sides after printing, and the print can shift a few millimetres on the press. Keep logos and text 10 mm inside every edge. Background colours can still run to the edge.

Where does the shipping label go?

Turn on “Keep space for the shipping label” and the editor marks a label-sized area on the front (100 × 150 mm, or smaller on small mailers). It warns you if your design runs under it.

Can you print on black, pink or metallic mailers?

Yes. On dark and metallic films we print over a white base so colours stay bright, or in one colour such as white ink, which keeps the film colour showing around it.

What logo files can I upload?

PNG, JPG or SVG. An SVG logo prints sharp at any size. For PNG and JPG files, the editor warns you if the logo is too small to print sharp.

Can I order one sample first?

Yes. Write “1 sample” in the quote form and we make a single printed sample of your design before a larger run.

Just need plain mailers?

We stock bubble mailers, padded envelopes and poly mailers in hundreds of sizes, ready to ship from Sydney and Melbourne.
