For high-volume business mailings
Use E4 mailing envelopes when you regularly need to send larger documents, catalogues or multiple sheets of paper at once. The 280×400 mm format offers enough space for A4 documents that you want to send flat without folding, or for sending several documents in one go.

Why choose the E4 format
This format is ideal if you often send thick document packs that won't fit in a standard C4 envelope. The 280×400 mm size gives you the flexibility to send both single A4 sheets and larger quantities of paper without the envelope becoming too tight.

Sturdy construction with gusset base
These envelopes have a gusset base with a 40 mm fold, allowing them to expand to hold thicker contents. The paper weight of 150 g/m² ensures the envelopes are sturdy enough to protect their contents during transit. The brown colour gives a professional, business-like appearance.

Practical considerations when in use
You receive 250 envelopes per pack, which is suitable for businesses that send mail regularly. Please note that these envelopes have no window, so you must write the address fully on the envelope or use an address label. The self-adhesive closure makes the mailing process efficient without the need for water or glue.
