MAILmedia Mailing Bag C4 P40288FeVE100 is a padded C4-size envelope designed to protect documents, brochures and flat items during postal and courier transport. The envelope combines a lightweight outer layer with internal padding to reduce the risk of bending and minimize damage from light impact. Its size matches C4 documents without folding, allowing reliable shipment of A4 sheets, certificates and slim printed materials.

Advantages

The padded construction offers shock absorption while keeping the overall weight low for economical postage. The envelope seals securely and provides a smooth outer surface that resists punctures and abrasion in typical handling. Consistent dimensions and a flat profile simplify packing, storage and automated processing in mailrooms. The design balances protection and cost-efficiency for routine mailings.

How to use

Insert the documents or flat items into the envelope so they lie flat against the inner padding.

Label the outer surface clearly with recipient and return address details according to postal guidelines.

Recommendations

For best results, avoid overfilling the envelope beyond its intended flat profile; when sending multiple sheets or thicker items, add a cardboard stiffener to maintain shape and prevent bending. Store unused envelopes in a dry environment away from direct sunlight to preserve adhesive performance and material integrity.
