Custom cardboard envelopes for secure shipping

Our range of custom cardboard envelopes provides essential protection for items that must remain flat during transit. Use these custom rigid mailers for sending artwork, photography prints, important certificates, catalogues, and thin books. The strong, rigid board construction prevents bending and creasing, while the built-in peel-and-seal adhesive strip ensures a quick, secure closure without extra tape.

Features of our printed cardboard envelopes

We supply a variety of printed cardboard envelopes to match your specific shipping needs. The Custom Cardboard Envelope is a versatile option, built from sturdy 350 gsm cardboard that is ideal for sending A4 or A5 documents, photos, or marketing materials. For items requiring more substantial protection, the Custom Corrugated Envelope provides enhanced rigidity thanks to its e-flute corrugated construction. This makes it a great choice for heavier items like hardback books or small electronics. Both of these solutions come in multiple standard sizes that align with common paper formats and fit within courier service dimensions. You can apply your branding across the entire surface of the envelope using full-colour CMYK digital printing. This process allows you to feature your logo, custom graphics, and brand colours vividly. The simple peel-and-seal closure streamlines your packing process, saving time on fulfilment. We supply all envelopes flat for convenient storage. These products are part of our wider assortment of shipping envelopes for all your mailing needs.
