Cardboard Envelopes

Cardboard envelopes provide essential protection for flat, delicate items that must not bend in transit. Ideal for shipping documents, photographs, art prints, and certificates, these mailers use a rigid board construction to maintain their shape. Every envelope includes a strong peel-and-seal adhesive strip for secure closure, streamlining your packing process and removing the need for extra tape.

Custom and plain cardboard envelopes

We offer a wide selection of customisable and unprinted cardboard envelopes to fit your brand's needs. You can apply your full-colour design, logo, or branding across the entire surface of the Custom Cardboard Envelope to create a memorable unboxing moment. For a more minimalist approach or for businesses that prefer to use their own stickers and labels, the Plain Cardboard Envelope provides a clean, professional look. We also supply corrugated options like the Custom Corrugated Envelope for items needing an extra layer of stiffness. You can order all our rigid envelopes in low minimum quantities, making them a practical choice for businesses of any size, from small Etsy shops to large corporate offices dispatching important paperwork. The sturdy build keeps your items in pristine condition, reflecting your brand's quality the moment it arrives.

Features of our rigid mailers

Our rigid mailers deliver efficiency and security. The self-sealing adhesive strip creates a strong, tamper-evident closure in seconds without needing tape. A built-in tear strip allows your customers to open the package easily upon arrival.

Corrugated and solid board rigid envelopes

Choose the right material for your specific shipping needs from our range of rigid envelopes. Solid board mailers are lightweight yet stiff, perfect for documents and photos. For slightly bulkier flat items like catalogues or thin books, corrugated mailers like the Plain Corrugated Envelope provide enhanced puncture resistance and rigidity. This material choice allows you to match the level of protection to the item you are sending, optimising both safety and shipping costs. If you need cushioning for more fragile items, consider our range of padded envelopes.
