Busta da spedizione MAILmedia C4 388370, autoadesiva, bianca, 22,3 g per pezzo

C4 mailing bag MAILmedia 388370 is a self-adhesive white mailer weighing 22.3 g per piece. Designed to hold documents and flat items in C4 format, the lightweight construction provides basic protection during handling and transit while keeping overall postage costs low. The peel-and-seal closure removes the need for separate tape and allows fast preparation of shipments in office, e-commerce and postal workflows.

Advantages

The mailer combines a thin, tear-resistant outer layer with a smooth interior that helps prevent abrasion of contents. Its self-adhesive strip ensures a consistent, dust- and moisture-reducing closure without additional consumables. At 22.3 g per piece, the bag minimizes added weight, which is beneficial for bulk mailing and cost-sensitive shipments. The neutral white surface is suitable for printing addresses and labels or attaching postage and barcodes.

Suitable for

• Sending A4 documents and certificates without folds
• Mailing flat promotional materials, catalogs and brochures
• E-commerce dispatch of small, flat products such as thin booklets or samples
• Internal mail and archive transfers where a sealed envelope is required

Key specifications

• Format: C4, suitable for flat A4-sized contents
• Material: lightweight mailer material with tear resistance
• Closure type: self-adhesive peel-and-seal strip
• Color: white external surface for labeling and postage
• Weight per piece: 22.3 g

How to use

Insert the documents or flat items into the mailer so they lay flat and aligned with the edges. Remove the protective strip to expose the adhesive band, then press firmly along the flap to seal the envelope. Apply postage, labels or printed addresses to the outer surface in visible positions. For irregularly shaped or heavy items, use a more protective packaging option rather than this lightweight mailer.

Recommendations

Store the mailers in a dry, cool place away from direct sunlight to preserve adhesive performance. For reliable sealing, ensure the sealing surface is clean and free of dust or oils. When sending important or valuable items, combine this mailer with additional internal padding or choose a more robust postal packaging to reduce risk of damage.
