Αυτοκόλλητος φάκελος MAILmedia DIN B4, βάρος 18,8 g

Self-adhesive envelope MAILmedia DIN B4, weight 18.8 g is a lightweight mailing envelope sized to fit B4 documents and materials. The envelope features a pressure-sensitive adhesive closure that seals quickly without the need for moisture, and its thin construction reduces postage costs while providing basic protection for contents during transit. The plain design and consistent dimensions make it suitable for routine office correspondence, bulk mailings and document storage.

Advantages

The envelope’s pressure-sensitive adhesive allows fast, reliable sealing without licking or wetting, saving time in high-volume mail operations. At 18.8 g the envelope is lighter than many standard B4 options, which helps lower postage expenses on each shipment. Its DIN B4 size accommodates unfolded documents, booklets and brochures while the consistent manufacturing ensures uniform thickness and predictable handling in postal machines and sorting equipment.

How to use

Insert documents so they lie flat within the envelope without exceeding the nominal B4 dimensions. Remove the protective strip from the adhesive flap and press firmly along the seal to ensure full contact and closure. For heavier contents or items with sharp edges, reinforce corners with tape or use an inner protective sleeve to prevent punctures. Ensure any required address labels, postage and customs documentation are affixed on the outer surface before dispatch.

Recommendations

Use the self-adhesive MAILmedia DIN B4 envelope for standard correspondence and lightweight mailings where cost-effective postage and quick sealing are priorities. Store envelopes flat in a dry environment to preserve adhesive performance and avoid exposure to high humidity or heat which can impair sealing.
