Features of our plain mailing envelopes

Our plain mailing envelopes provide a straightforward packaging solution for businesses that prefer a minimalist look or apply their own branding with stickers or stamps. We supply them in classic white or natural brown kraft paper finishes, available directly from stock. This allows for low minimum order quantities and fast dispatch, ideal for testing new products or managing inventory.

Plain padded envelopes and other plain mailing envelopes

When you need to protect items from bending, our rigid mailers offer excellent security. The Plain Cardboard Envelope uses sturdy 350 gsm cardstock and comes in multiple sizes designed to fit standard paper formats like A4 and A5, making it perfect for documents, photos, and art prints. For heavier or more fragile flat items like catalogues or small electronics, the Plain Corrugated Envelope provides enhanced stiffness with its E-flute corrugated construction. Both of these plain envelopes feature a secure self-seal adhesive strip for quick packing and a tear-strip for easy opening. When shipping delicate products that require cushioning, our Plain Bubble Envelope is the standard choice. Its interior bubble lining absorbs shocks during transit, while the kraft paper exterior provides a durable surface. These plain padded envelopes are lightweight to help manage shipping costs and come in a wide range of sizes. You can also attach shipping documents securely to any parcel with an Adhesive Shipping Label Pouch, which keeps invoices and customs forms visible and protected during transit.
