Self-adhesive C5 mailing bags MAILmedia 35146/0 with front window

MAILmedia Self-adhesive C5 mailing bags model 35146/0 are designed for secure and efficient shipping of C5-sized documents and small items. Each bag features a peel-and-seal adhesive closure that eliminates the need for extra tape and a clear front window that makes recipient addresses or invoice slips visible without additional labelling. The lightweight yet durable construction protects contents from dust and light handling during transit while keeping packing fast and consistent.

Advantages

These C5 mailing bags combine a tamper-evident peel-and-seal closure with a transparent front window to simplify postage and delivery handling. Their material resists tearing and moisture to a practical degree for normal postal transport, and the pre-applied adhesive strip speeds up packing operations. The front window reduces the need to print or stick separate address labels and helps ensure address information remains legible throughout shipment.

Suitable for

• Shipping C5 documents such as letters, invoices and certificates
• Dispatching small, flat retail items and samples
• Mailing orders where a visible invoice or packing list is required
• Bulk mailing operations requiring fast sealing and consistent presentation

Key specifications

• Format: C5 (suitable for documents up to C5 size)
• Closure type: Peel-and-seal adhesive strip for single-step sealing
• Window: Transparent front window for visible address or invoice
• Material: Lightweight protective film suitable for postal use
• Protection: Resists everyday handling, dust and light moisture during transit

How to use

Insert the C5-sized document or small flat item so that the address or invoice aligns with the front window if a visible document is required. Peel off the protective liner from the adhesive strip, fold the flap down and press firmly along the seal to ensure a secure closure. For best results, press along the entire length of the adhesive to create even contact and to minimise the risk of the bag opening during handling.

Usage recommendations

Use these mailing bags for standard postal services and courier shipments. Do not overfill beyond the bag’s flat capacity; avoid enclosing bulky or sharp items without additional internal protection. Store unused bags flat in a dry environment and apply postage compliant with your carrier’s guidelines.
