Envelope MAILmedia 112 x 225 mm with window, patented closure technology

MAILmedia envelope 112 x 225 mm with a clear address window and patented closure technology provides a practical solution for sending letters, invoices and documents that match the envelope dimensions. The transparent window aligns with standard address placement to simplify automated handling and manual processing. The patented closure is designed to deliver a secure seal while reducing the risk of accidental opening during transport.

Advantages

The transparent window eliminates the need for separate address labels, saving preparation time and ensuring the address remains visible and protected. Patented closure technology offers improved sealing strength and tamper resistance compared with standard gummed or peel-and-seal closures, contributing to reliable transit security. The envelope dimensions are compatible with common document sizes folded to fit, and the construction provides consistent feedability in office printers and mailing machines.

Suitable for

• Mailing invoices and statements
• Sending personal or business correspondence
• Bulk mailing from printers and mailing systems
• Administrative and office document dispatch

Key specifications

• Outer dimensions: 112 x 225 mm
• Transparent address window for visible recipient information
• Patented closure technology for enhanced sealing and tamper resistance
• Compatible with standard folded documents that fit the envelope size
• Constructed for reliable feeding in office printers and mailing machines

How to use

Insert the document so the address shows through the transparent window, ensuring the recipient details align with the window area. Engage the patented closure according to the product’s closure mechanism—press or lock the seal as designed to achieve a secure fit. For machine processing, verify orientation and feed direction to match your printer or mailing system guidelines. Handle sealed envelopes by the edges to preserve integrity of the closure.

Recommendations

For best results, use documents folded to the envelope size so the address appears correctly in the window. When preparing large batches, test a small run through your printer or mailing machine to confirm alignment and feed reliability. Store envelopes flat in a dry environment to maintain closure performance.
