Key specifications
 Format: C5, suitable for A5 or A4 folded once
 Window: none (opaque)
 Closure: patented mechanical closure technology for secure sealing
 Material: paper envelope designed for standard mailing use
 Compatibility: compatible with manual and many automated mailing feeders
How to use
Insert the document or folded sheet into the envelope so that contents lie flat and do not exceed the envelope’s dimensions. Engage the patented closure according to the built-in mechanism — typically by aligning the flap and pressing along the closure area until it locks. Ensure edges are flush and verify the seal integrity before transporting or loading into mailing equipment. Do not overload the envelope or force bulky items through the closure.
Usage recommendations
For reliable results, use with standard-weight paper documents and avoid inserting thick card stock or multiple bulky pages. Store envelopes in a dry, room-temperature environment to preserve closure function and paper quality. When preparing bulk mailings, test the envelope and closure with your mailing equipment to confirm compatibility and feed performance.
