E5 Envelope (156x220) – Efficient and Secure Business Correspondence
Format: E5 (156x220 mm)
Paper: 80g white offset
In a daily business environment, the volume of outgoing mail can be high, making the right mailing envelope not just a communication tool, but a time management asset. This E5 window model is designed for professionals who value speed, security, and aesthetics.
1. Maximum Confidentiality and Security
One of the key advantages of this envelope is its blue interior lining. This is not just a design element, but a functional feature that ensures total correspondence privacy. The content cannot be read through the paper, even when held against the light. This is critical when sending invoices, contracts, or documents containing personal data.
2. Process Automation with a Window
This envelope features a 30x90 mm window on the left side, offering significant time savings:
- No Manual Addressing: A correctly folded letter allows the recipient's address to be seen directly through the window.
- Error Prevention: It reduces the risk of putting a letter into an envelope with the wrong address, as the address is visible directly from the document.
- Professional Look: Printed text in the window looks much more solid than a handwritten address.
3. Convenient and Fast Sealing
The envelopes are equipped with a peel-and-seal strip (HK - hot melt technology). This means you no longer need to moisten the adhesive layer—simply remove the protective strip and press firmly. The adhesive is extremely strong, ensuring the envelope won't open during transit, regardless of temperature fluctuations.

Frequently Asked Questions (FAQ)
Is this envelope printer-friendly?
While envelopes can be printed on, this model with a window and peel-and-seal strip is primarily designed for inserting pre-prepared documents. If you plan to print directly on the envelope, consult your equipment provider regarding heat impact on the adhesive strip.
Which side is the window on?
The window is located on the left side of the envelope, so when preparing documents for printing, the recipient's address should be aligned to the left of the page.
What is the purpose of the E5 format?
The E5 format (156x220 mm) is slightly larger than the standard C5, making it easier to insert a thicker stack of A4 sheets folded in half.
