Envelope HERLITZ C5 with self-adhesive strip, window in middle (right/left), white, 500 pcs

Pack of 500 HERLITZ C5 envelopes designed for mailing, invoicing and document storage. These white C5 envelopes include a self-adhesive strip for quick and secure closure and a central transparent window that exposes recipient information printed on internal documents. The window is placed to suit both right- and left-positioned content, making the envelopes compatible with common invoice and mailing formats used in offices and bulk-post operations.

Advantages

The self-adhesive strip provides reliable closure without the need for moisture or additional fastening materials, saving time during preparation of large mailings. The central window reduces the need to print addresses on the envelope itself and ensures recipient details are visible while keeping the envelope surface clean and professional. A pack of 500 supports high-volume use and reduces the frequency of reordering for office and administrative needs.

Suitable for

• Office correspondence and invoicing
• Bulk mailings and marketing materials

• Accounting departments and billing centers

Key specifications

• Color: white
• Closure type: self-adhesive strip (peel-and-seal)

How to use

Insert the document so that the recipient address aligns with the envelope window. Remove the protective strip to expose the adhesive and press the flap firmly to seal. For automated inserting machines, confirm window alignment with your folding and inserting settings; these envelopes are compatible with standard office mailing equipment. Store unopened packs flat in a dry environment to maintain adhesive performance and prevent window distortion.

Usage recommendations

For best results, use documents folded or formatted to match the central window position; test a sample in mailing machines before large runs. Keep packs away from excessive heat and humidity to preserve the self-adhesive strip’s effectiveness and the clarity of the window.
