## Long description

Envelope with silicone tape Office Products HK B4 250×353 mm 90 g/m² 250 pcs brown is a pack of standardized B4 envelopes designed for sending and storing documents and flat items. Each envelope measures 250×353 mm and is made from 90 g/m² paper in a brown finish. The envelopes come with a pre-applied silicone sealing tape that provides a secure, tamper-resistant closure without the need for moistening, simplifying handling in office and postal workflows.
Advantages
The silicone tape offers fast, reliable closure and reduces handling time compared with traditional gummed flaps. The 90 g/m² paper balances rigidity and flexibility, protecting contents while remaining easy to fold and insert documents. Pack of 250 supports bulk use in offices, archives and mailing operations, and the brown color masks minor scuffs during transit. The B4 format accommodates unfolded A4 documents or multiple sheets, reducing the need for additional folding.
Suitable for
Mailing unfolded A4 documents and certificates
Office correspondence and administrative dispatches
Archiving paperwork and storing reports
Bulk mailing and postal distribution
Key specifications
Size: 250 × 353 mm (B4 формат)
Material weight: 90 g/m² paper
Closure: pre-applied silicone sealing tape (peel-and-seal)
Color: brown

How to use
Insert documents or flat items into the envelope so they lie flat and do not overfill the flap area. Peel off the silicone tape backing and press the flap firmly along the adhesive strip to secure the closure. For heavy or sensitive contents consider reinforcing the seal or using additional tape. Store unused envelopes in a dry, cool place to maintain paper integrity and adhesive performance.
Usage recommendations
Use these B4 envelopes when you need a quick, reliable seal without moistening; they are suitable for regular office mailing, archiving and situations where unfolded A4 documents should remain flat. For international or registered mail, verify postal requirements and add any required labels or protective inserts.
