Kuvert B4 250x40x353 mm 130 g/m² is a paper envelope sized to accommodate B4-format documents and folded materials. Constructed from 130 g/m² paper, it offers a balance between flexibility and durability for mailing, filing and short-term storage of larger documents. The envelope features dimensions 250 x 40 x 353 mm, providing ample internal space while remaining compatible with standard postal handling and office storage systems.

Advantages

The 130 g/m² paper weight gives this Kuvert envelope better tear and crease resistance than lightweight mailing papers while remaining easy to write on and affix labels. Its B4-compatible dimensions reduce the need for additional folding of larger sheets and keep documents flat during transport. The envelope’s neutral construction supports printing of addresses or logos and is suitable for automated sorting equipment when standard addressing is applied.

How to use

Insert documents so they lie flat inside the envelope and avoid overfilling beyond the measured depth to prevent tearing or deformation. Close and seal according to the envelope’s closure type; when using adhesive seals, press firmly along the flap to ensure adhesion. For mailing, place address information or a printed label on the front center area and add postage according to carrier requirements. Store unused envelopes in a dry, cool place to maintain paper quality.

Usage recommendations

For best results when sending important documents, use a cardboard stiffener inside the envelope to reduce bending during transit; when bulk mailing, verify carrier size and weight limits and label placement for automated sorting.
