The County Stationery C4 Peel & Seal Envelopes are designed for administrative professionals, office managers, and individuals who frequently mail documents that must remain unfolded. These envelopes provide the benefit of a quick, mess-free sealing process, though users should note that the 90gsm paper weight is standard and may not be suitable for heavy-duty archival storage or rigid items.

Yes, a folded A3 document will fit comfortably within the 324mm x 229mm dimensions.
The 90gsm paper is standard thickness. While it hides text well, very dark or bold printing may be slightly visible if held up to strong light.
No, the adhesive is contained to the flap and should not leave residue on your documents.
Keep them in their original packaging in a desk drawer away from heat sources to maintain the freshness of the adhesive.
Yes, C4 is a standard international size, though you should check your local postal service requirements for weight and thickness limits.
Ensure the envelope is not overstuffed, which causes tension on the seal. Press firmly across the full length of the adhesive strip for five seconds.
Adjust your printer settings to 'Envelope' or 'Heavy Paper' and ensure the flap is folded correctly according to your printer's manual.
To ensure the best results, place your unfolded A4 document squarely into the envelope to avoid catching the edges on the adhesive strip. When sealing, firmly press across the entire length of the flap to ensure the adhesive bond is secure. For storage, keep the envelopes in a cool, dry place away from direct sunlight; moisture and heat can degrade the adhesive strip over long periods. If you are printing directly onto these envelopes, ensure your printer is set to a heavy-paper or envelope setting to avoid jamming or smearing the ink.
