Busta C6-5 MAILmedia 202340 adesiva con finestra per lettere e documenti

C6-5 MAILmedia 202340 self-adhesive envelope with window is designed for sending letters and documents in a compact, professional format. The envelope includes a transparent address window that keeps recipient details visible when an inserted document is aligned correctly. A peel-and-seal closure enables fast and hygienic sealing without moistening, simplifying mail preparation in offices, mailrooms and service counters.

Advantages

The transparent window reduces manual addressing and ensures readable recipient information when standard document layouts are used. The self-adhesive peel-and-seal strip saves time and provides consistent closure strength for secure transport. The envelope is sized to fit standard folded documents and offers a clean, professional appearance for business correspondence.

Suitable for

• Business letters and invoices
• Client statements and notifications
• Mailing of folded A4 documents
• Mass mailing and bulk dispatch operations
• Office, accounting and administrative departments

Key specifications

• Format: C6-5 size suitable for folded A4 and A5 inserts
• Closure: Peel-and-seal self-adhesive strip for quick fastening
• Window: Transparent address window for visible recipient details
• Material: Paper envelope designed for machine or manual handling
• Use case: Single-sheet letters and multi-page folded documents

How to use

Insert the letter or document so the recipient address aligns with the transparent window. Remove the protective strip from the peel-and-seal adhesive and press the flap firmly to secure the closure. For automated processing, ensure documents are folded and aligned consistently to maintain address visibility through the window. Handle envelopes gently to avoid creasing near the window area.

Recommendations

Store envelopes flat in a dry environment to preserve adhesive quality and avoid moisture exposure. For optimal address visibility, use standard document templates that position the recipient details within the window area. When preparing large mailings, perform a test run to confirm alignment and machine compatibility.
