Mailing bag MAILmedia C4 384157 self-adhesive brown 16.6 g – lightweight document envelope

MAILmedia C4 384157 is a self-adhesive brown mailing bag with a lightweight construction of approximately 16.6 g, designed to hold A4 documents and other flat items without folding. The envelope combines tear-resistant paper with a peel-and-seal closure, providing a straightforward packaging solution for office correspondence, e-commerce parcels and routine document transport while keeping contents protected from light handling during transit.

Advantages

The lightweight 16.6 g construction reduces postage costs while maintaining sufficient strength for standard document shipments. The self-adhesive peel-and-seal strip enables fast and secure sealing without tape. The brown exterior offers a neutral, professional appearance and provides modest resistance to scuffs and dirt. The flat, C4 format accommodates A4 sheets and slim booklets, eliminating the need to fold documents.

Suitable for

• Sending A4 documents and contracts without folding
• Dispatching invoices, statements and certificates
• Small e-commerce orders with flat items (brochures, photographs, thin catalogs)
• General office mailing and administrative correspondence

Key specifications

• Format: C4, fits A4 sheets flat
• Material: brown kraft-style paper with reinforced structure
• Weight: approx. 16.6 g per envelope
• Closure: self-adhesive peel-and-seal strip
• Intended use: single-envelope document mailing

How to use

Insert the A4 documents or flat items into the envelope so they lie flat and aligned with the edges. Peel off the protective strip from the adhesive flap, fold the flap down and press firmly along the seal to secure the envelope. For added protection, consider placing delicate contents in a protective sleeve before inserting into the mailing bag.

Usage recommendations

Use the MAILmedia C4 envelope for standard document shipments where low weight and simple sealing are priorities. Avoid overfilling beyond the envelope’s flat capacity and do not use for bulky or sharp items. For high-value or fragile contents, add internal protective padding or choose a sturdier postal packaging option.
