Cardboard envelopes & rigid mailers
Rigid board envelopes and mailers for items that must arrive flat and undamaged - photographs, certificates, artwork, documents and thin printed goods. The range includes solid-board cardboard envelopes, corrugated pocket envelopes and pillow envelopes. All are UK-stocked and despatched the same working day before the daily cut-off, with VAT-exclusive pricing that falls as you buy more.
Rigid vs semi-rigid
Solid-board cardboard envelopes are stiff and ‘please do not bend’ by design, ideal for photos and certificates. Corrugated pocket envelopes add a fluted layer for light cushioning on slim goods, while pillow envelopes give a slight puffed profile for small, awkward items.
Flat, protected and postage-aware
Because they resist bending, cardboard envelopes reduce damage claims on flat goods. Many stay within the Royal Mail Large Letter profile to keep postage down - check each product's dimensions. For book-specific formats see book & magazine mailers.

Frequently Asked Questions
Will a cardboard envelope stop my item bending in the post?
Yes - solid-board cardboard envelopes are rigid by design, so photos, certificates and artwork stay flat. Corrugated pocket envelopes add light cushioning for slim goods that also need a little protection.
What can I send in a cardboard envelope?
They suit flat, thin items: photographs, certificates, prints, documents, thin accessories and slim printed goods. For thicker or fragile items, consider padded mailers.
Are cardboard envelopes recyclable?
Yes - they're board-based, plastic-free and widely recyclable in standard kerbside collections.
Do they qualify for Royal Mail Large Letter postage?
Many sizes are designed to stay within the Large Letter profile (up to 353 × 250 × 25mm). Confirm the product's dimensions and your packed thickness against your postage band before ordering.
Can I get cardboard envelopes printed?
Yes. Upload your artwork online and approve a free sample before production, roughly a 72-hour turnaround. See personalised cardboard envelopes.
How quickly do they ship?
