MAILmedia C4 Brown folding bags are made from 130 g/m² kraft paper and designed to hold C4-size documents and other flat items. Supplied as a pack of 40, each bag folds closed to protect contents during mailing or storage while maintaining a neat, professional appearance. The lightweight construction keeps postage costs low and the brown kraft finish offers a simple, recyclable packaging solution for routine office correspondence.

How to use

Insert flat documents or items into the bag so they lie flat and aligned with the bag edges. Fold the flaps according to the pre-creased lines to enclose the contents securely; the design relies on folding for closure without additional adhesives. For mailing, ensure the document is fully contained and the folded edges are seated firmly to prevent shifting. Address and delivery information can be written directly on the bag or attached as a label.

Usage recommendations

Use these folding bags for single-sheet or thin multi-sheet mailings; avoid overstuffing to preserve closure integrity. For heavy or valuable contents, combine with an outer padded envelope or protective insert. Store packs flat and in dry conditions to maintain paper stiffness and folding accuracy.
