Kirjekuori MAILmedia C5 248140 itseliimautuva ikkunallinen, valkoinen

MAILmedia C5 envelope model 248140 is a white self-adhesive envelope with a window designed to accommodate C5-size documents. The envelope offers a peel-and-seal closure for fast, reliable sealing without moistening, and a transparent window that displays recipient information printed on enclosed documents. Constructed for routine office use, it streamlines mailing of invoices, statements, letters and administrative paperwork.

Advantages

The self-adhesive closure provides secure, consistent sealing and reduces handling time compared with traditional gummed envelopes. A clear window removes the need to print addresses on the envelope itself, saving time and ensuring address accuracy when documents are prepared using templates. The white exterior ensures a neutral, professional appearance and good contrast for labels and postal marks. The envelope's dimensions correspond to standard C5 documents, allowing items to be mailed flat without folding when suitable.

Suitable for

• Business correspondence and office mailings
• Invoicing and statements with printed recipient address
• Sending contracts, brochures and flat documents fitting C5 format
• Administrative mail where quick sealing and address visibility are required

Key specifications

• Format: C5-compatible (fits C5-size documents)
• Closure type: self-adhesive peel-and-seal flap
• Window: transparent address window positioned for document alignment
• Color: white exterior for clear label/print contrast
• Material: paper envelope suitable for standard postal handling

How to use

Insert the document so the printed recipient address aligns with the transparent window. Remove the protective strip from the adhesive flap and press the flap down firmly along the seam to seal. For documents that must remain flat, ensure the contents match C5 dimensions or use appropriate internal folding to avoid stress on the window area. Handle sealed envelopes according to your postal or courier service guidelines.

Recommendations

Store envelopes flat in a dry, cool place to preserve the adhesive strip and prevent warping. When preparing bulk mailings, use document templates that place the recipient address precisely in the area visible through the window to avoid reprints or address misalignment.
