Self-adhesive envelopes Office Products C4 229×324 mm 90gsm 250 pcs white are designed to hold unfolded A4 documents securely and present them with a clean, professional appearance. Each envelope is made from 90 gsm white paper and features a peel-and-seal flap for quick, reliable closure. The pack contains 250 envelopes sized 229 × 324 mm, suitable for business correspondence, invoices, contracts and archival document storage.

Advantages

The 90 gsm paper provides sufficient opacity to protect confidential contents and maintains a flat shape for mailing without folding standard A4 sheets. The white surface offers good contrast for printed addresses and labels, and the peel-and-seal system eliminates the need for additional moistening or adhesive tape.

How to use

Usage recommendations

For best results, avoid overfilling the envelopes and ensure adhesive strips are free from dust or debris. When using inkjet printing for addresses, allow printing to dry fully before sealing and handling. Keep packs in a cool, dry place to preserve paper quality and adhesive performance.
