Mailing envelope MAILmedia B5 90 g/m², pack of 500 is a set of paper envelopes sized to fit B5 documents and flat items.

A pack of 500 reduces the frequency of reordering and supports high-throughput mailing operations without individual packaging waste.

How to use

Insert the document or flat item into the envelope so the edges align with the envelope opening. Ensure the contents lie flat to maintain protection during transport. Close the envelope securely according to its closure type: peel and seal if adhesive, or fold the flap if it is a tuck-in design. For postal use, attach the correct postage and address information on the front face, avoiding overlap with seams or closures.

Usage recommendations

Store envelopes flat in a dry environment away from direct sunlight and humidity to preserve paper stiffness and adhesive performance. When sending items of greater thickness or value, consider additional protection such as cardboard stiffeners or using a heavier-duty envelope.
