The C5 Window Envelope (WX3406) is an essential stationery solution for office managers and administrative professionals looking to streamline their outgoing correspondence. These envelopes offer the convenience of a self-seal closure and a precision-cut window, making them ideal for high-volume invoice or letter mailing; however, the 90gsm paper weight is standard, meaning they are best suited for standard documents rather than heavy cardstock inserts.

Yes, but you will need to fold the A4 sheet twice to fit it comfortably inside the envelope.

No, it features a self-seal closure that activates with pressure.
The 90gsm paper is standard thickness and provides reasonable opacity for typical business correspondence.
Ensure the envelope is not overfilled and apply firmer, consistent pressure across the entire adhesive strip.
Check your document margins against a 57mm left-side and 20mm bottom-side offset to match the window position.
Check the storage environment for excessive humidity or heat, which can affect the adhesive properties.
To ensure the best results, verify that your printer templates are set to align addresses within the 90 x 45mm window area. For storage, keep the envelopes in a cool, dry place away from direct sunlight to prevent the adhesive strip from drying out or premature activation. To seal, simply fold the flap over and apply firm pressure across the adhesive line. Avoid overstuffing the envelopes to ensure the self-seal strip maintains a secure hold throughout the transit process.
