Self-adhesive B5 envelopes NC Koperty 25 pcs, white, peel-and-seal

NC Koperty self-adhesive B5 envelopes, pack of 25 in white, are designed to hold B5-sized documents, correspondence and printed materials. Each envelope features a peel-and-seal closure that enables fast, clean sealing without the need to moisten the flap. The envelopes are intended for everyday office tasks such as mailing invoices, sending letters and organizing documents where a standard B5 format and a reliable adhesive closure are required.

Advantages

These B5 envelopes combine a standard document size with a practical self-adhesive strip for quick sealing. The white surface provides a neutral backdrop for handwritten or printed addresses and labels. The peel-and-seal mechanism reduces handling time compared with water-activated closures and eliminates the need for additional tape or glue, improving efficiency for bulk mailings and routine office use.

Suitable for

• Mailing invoices, statements and business correspondence
• Sending brochures, leaflets and promotional materials in B5 format
• Organizing and storing B5 documents in offices and archives
• Mailings that require quick, single-person sealing

Key specifications

How to use

Insert the B5 document into the envelope so that the contents lie flat and do not overfill the envelope. Remove the protective strip from the adhesive on the flap, align the flap with the back of the envelope and press firmly along the seam to ensure a secure seal. For best results when sending multiple envelopes, press each seal for a few seconds to confirm adhesion. If labels or addresses are applied, ensure the surface is clean and dry before sticking.

Usage recommendations

Store unopened packs in a dry, cool place away from direct sunlight and high humidity to preserve adhesive performance. Avoid overfilling envelopes to maintain seal integrity during transit. For machine processing or bulk franking, verify compatibility with your mailing equipment before large-scale use.
