A C5 envelope (229 x 162 mm) can typically hold an A4 sheet of paper folded in half, or other documents up to that size, such as greeting cards or brochures.
The peel and seal closure provides a strong, tamper-evident seal that is more secure than standard gummed envelopes and offers convenience without the need for moisture.
Once applied and pressed, the peel and seal strip creates a permanent bond. It is not designed for re-sealing if it has already been activated.
The window measures 45mm high by 90mm wide. It is positioned 60mm from the bottom edge and 20mm from the left edge of the envelope.
The 100 gsm paper is suitable for standard office printing and addressing, but thorough testing is recommended if using high-volume or specialized printing methods.
When stored correctly in a cool, dry place, the adhesive typically maintains its effectiveness for an extended period, often over a year.
Ensure the strip and the envelope flap are clean and dry. Humidity or dust can interfere with adhesion. Press firmly along the entire seal for at least 15 seconds.
Verify that the recipient's address is printed or written within the designated window area (45x90mm, 60mm up, 20mm from left). Adjust your mail merge or printing settings if necessary.
While 100 gsm is standard, for very sensitive or rigid contents, consider using a heavier weight envelope or inserting a card for support.
Setup: These envelopes require no setup beyond filling them with your documents and sealing them using the peel and seal strip. Ensure the surface of the strip and the area it adheres to are clean and dry for optimal adhesion.
Compatibility: The C5 size is compatible with documents that fit within 229 x 162 mm, such as A4 paper folded once. The window dimensions (45 x 90mm) are designed to accommodate standard address block formats. Always check if your printed address aligns correctly with the window's position before sealing.
Care: Store envelopes in a cool, dry place away from direct sunlight to maintain the integrity of the paper and the adhesive strip. Avoid exposing them to excessive moisture, which can affect sealing performance.
