Envelope MAILmedia C5 90 g/m² self-adhesive with window 162 x 229 mm

Envelope MAILmedia C5 90 g/m² self-adhesive with window 162 x 229 mm is a standard C5 envelope designed for reliable everyday mailing. Made from 90 g/m² paper, the envelope provides a balance between stiffness and flexibility while the transparent window allows recipient address visibility without additional labeling. The self-adhesive closure ensures fast and secure sealing for business correspondence, invoices and documents that fit the C5 format.

Advantages

The envelope combines a robust 90 g/m² paper weight with a clear address window to reduce handling time and eliminate the need for separate address labels. The self-adhesive strip creates a tamper-resistant closure and speeds up preparation of batches of mail. The C5 size (162 x 229 mm) fits A4 documents folded in half or A5 inserts, making it suitable for invoices, letters and single-sheet documents.

Key specifications

• Material weight: 90 g/m² paper
• Closure type: self-adhesive strip
• Feature: transparent window for address display

How to use

Insert the document so the recipient address aligns with the transparent window. Remove the protective strip from the self-adhesive closure and press firmly along the flap to seal. For bulk preparation, position documents consistently to ensure addresses are visible through the window before sealing. Store envelopes flat in a dry place to preserve the adhesive performance and paper quality.

Recommendations

To ensure clear visibility through the window, use standard address placement on the inner document and avoid bulky inserts that can distort the window area. For important or confidential contents consider using additional inner covers or security sleeves. Keep envelopes in their original packaging until use to protect the adhesive strip from dust and humidity.
