Custom Cardboard Envelopes

Printed cardboard envelopes provide a rigid and protective solution for mailing flat items that must not be bent. With options for full-colour printing, businesses can send documents, photographs, or marketing materials in packaging that displays their brand identity. The range includes several sizes and material options, all featuring a secure peel-and-seal adhesive strip for quick packing.

Custom cardboard envelopes for business shipping

This category includes several types of custom board back envelopes tailored for different shipping needs. The Custom Cardboard Envelope is a classic choice, constructed from sturdy 350 gsm rigid board to prevent creasing. For items requiring more substantial protection, the Custom Corrugated Envelope offers an extra layer of durability with its fluted construction. Both styles are ideal for posting A4 or A5 documents, certificates, books, and artwork without damage. The sizes fit common paper dimensions and postal service requirements, ensuring a snug fit and efficient dispatch. We offer these mailers starting from low minimum order quantities, making them accessible for businesses of all sizes. All options come with a simple self-adhesive closure, streamlining the packaging process for busy teams.

Designing your printed cardboard envelopes

You can personalise the entire surface of your printed cardboard envelopes. We apply your branding, logo, or complete artwork in vibrant, full-colour CMYK print. This process transforms a standard mailer into a professional marketing tool that represents your business from the moment it arrives.

These mailers combine practicality with effective branding. For an unprinted alternative, see our standard cardboard envelopes, which offer the same structural protection. Choose the right mailer to ensure your flat items arrive in perfect condition.
