Folding shipping bag MAILmedia 51652 C4 is a white self-adhesive mailing solution made from 140 g/m² paper, designed for sending documents and other flat items.

Its folded form and paper construction provide lightweight protection and an uncomplicated packing process suitable for office, e‑commerce and postal use.

Advantages

The 140 g/m² paper offers a balance of stiffness and flexibility that keeps contents flat while remaining easy to fold. The self-adhesive flap with a 4 cm width ensures a reliable seal and consistent closure across shipments. As a paper-based product, the bag is easy to write on for addressing and labeling. The white surface delivers a neutral, professional look and is compatible with standard postal handling.

Suitable for

• Shipping documents, letters and certificates in C4 format

• Small e‑commerce shipments of flat items such as photographs or thin manuals

How to use

Place the document or flat item into the unfolded bag and fold along the pre-creased edges to form the mailing envelope.

Use the bag for documents and flat items that do not require rigid protection; for fragile or bulky objects, combine with additional padding or choose a rigid mailing box. Store unopened packs in a dry environment to maintain adhesive performance and paper integrity.
