MAILmedia C4 38106/7 brown recyclable paper mailing bags are designed to carry documents and flat items in C4 format.

The flat envelope format accommodates unfolded A4 documents and similar items, offering protection during transit while minimizing bulk.

Advantages

The neutral brown color is suitable for professional correspondence and bulk shipments. As recyclable packaging, these mailing bags support waste reduction and easier disposal compared with mixed-material alternatives.

How to use

Insert documents flat into the C4 mailing bag so that contents lie evenly and do not cause bulges. Fold the flap and seal securely using the recommended adhesive or tape suitable for paper envelopes; ensure edges are aligned to prevent catching during sorting. For documents requiring additional protection, consider adding a thin cardboard insert inside the bag before sealing. Address and postage information should be applied to the exterior in a clear, legible manner, keeping the central area free of obstructions.

Use these mailing bags for standard office mailings and non-fragile flat items. Avoid exposing sealed bags to sustained moisture; for shipments requiring water resistance, combine with a suitable outer protective layer. Store unused bags flat in a dry environment to maintain shape and ensure reliable sealing.
