Itseliimautuva kirjekuori MAILmedia B4 kierrätys 110 g/m² harmaa, 24,3 g

MAILmedia self-adhesive envelope in B4 format is made from recycled paper with a grammage of 110 g/m² and a neutral grey finish. The envelope weighs 24.3 g and is designed for sending documents, brochures and flat items that fit the B4 size. A peel-off strip on the flap provides a secure adhesive closure without the need for additional tape, while the recycled material supports easier disposal and recycling after use.

Advantages

The envelope combines a robust paper weight with a convenient self-seal closure, allowing fast and reliable mailing workflows. Its recycled-fibre construction reduces demand for virgin materials and simplifies end-of-life processing. Neutral grey colouring conceals minor marks and is suitable for professional correspondence, while the B4 dimensions accommodate unfolded A4 documents or multiple sheets and brochures.

Suitable for

• Mailing A4 documents without folding
• Sending brochures, catalogs and flat marketing materials
• Office correspondence and archival shipments
• Enclosing certificates, invoices and contracts

How to use

Insert the document or flat item into the open end of the envelope so it sits flush within the B4 dimensions. Remove the protective strip covering the adhesive on the flap, fold the flap down and press along the sealed edge to engage the adhesive. For bulky or heavy contents, reinforce the closure with additional tape if required and ensure postage meets carrier weight and size limits.

Recommendations

Store envelopes flat in a dry environment to preserve the adhesive strip and avoid moisture-related weakening. For archival use, let ink and labels dry fully before sealing. Use the B4 recycled envelopes when a balance of sturdiness and environmental consideration is preferred.
