Envelopes & Mailing Bags

Send documents and files discreetly and safely!

From sending files and letters to storing and itemising documents, envelopes are useful for a wide variety of applications. Our envelope selection includes a wide variety of sizes and styles, including C5 envelopes, DL envelopes and square envelopes, all suitable for shipping via Royal Mail. For eco-friendly workplaces, we supply business envelopes made from recycled paper material, minimising your impact.

If you need a plain and simple white or brown business envelope, you'll find everything you need right here. We stock various standardised formats such as C4, C5 and C6, with styles including gummed gusset, self-seal, adhesive strip and peel-and-seal. For business needs, a high-quality seal is essential for ensuring privacy when sending documents and files. A window envelope adds a professional look to your letters, allowing for letterhead's and addresses to be printed and displayed whilst the contents remain discreet. Sealing strips are highlighted with a white peel cover, making it quick and easy to seal and send important documents and letters.

If you're posting items that are delicate or have a high financial and/or sentimental value, choose our protective envelopes, which are designed with extra-thick material to keep your items safe and secure. You could also consider our coloured mailing envelopes, which are available in white, green or orange and also have strong, thick material for maximum protection. If you have more-specific postage requirements, we also stock a range of specialist mailing envelopes such as CD envelopes or polythene bags for textiles products or files.
