Sobre de envío MAILmedia C4 100 g/m² blanco — formato C4, papel 100 g/m²

MAILmedia Versandtasche C4 100 g/m² white is a C4-size mailing envelope made from 100 g/m² paper, sized to hold unfolded A4 documents and flat materials. The envelope offers a smooth white surface suitable for printing address details, labels or company logos and provides a lightweight protective layer for correspondence, invoices, brochures and similar single-sheet or thin multi-page content. Its standard format is compatible with common postal requirements and office handling workflows.

Advantages

The envelope combines a standard C4 form factor with medium-weight 100 g/m² paper for a balance of economy and tear resistance. The white paper surface ensures good readability of printed or handwritten addresses and supports basic thermal and inkjet printing methods where applicable. The slim profile reduces postage costs compared with padded alternatives while still shielding documents from creasing and light dirt during transit.

Suitable for

• Sending unfolded A4 documents such as contracts, invoices and certificates
• Mailing brochures, flyers and promotional sheets
• Office correspondence and administrative dispatches
• Archiving or transporting flat samples, photos and thin reports

Key specifications

• Format: C4 (sized to accommodate unfolded A4)
• Material weight: 100 g/m² paper
• Color: white
• Profile: flat mailing envelope for single-sheet or thin multi-page contents

How to use

Insert the unfolded A4 documents or flat items into the envelope, aligning contents to avoid bulging at the flap. Close the envelope according to the closure type provided (if self-seal, remove the strip and press firmly; if gum-seal, moisten the adhesive and press). Affix address information and postage on the front face, ensuring that any printed barcodes or postage marks are clearly visible and unobstructed. For heavier or thicker contents, use additional reinforcement or choose a heavier mailing option.

Recommendations

For reliable postal handling, avoid overfilling and ensure edges are straight; use clear adhesive labels for printed addresses if using thermal transfer or laser printers that may not be compatible with very smooth or coated surfaces.
