Product Information

Full details

The Q-Connect C5 Window Pocket Envelopes (KF03290) are designed for office professionals and administrative staff who require a streamlined solution for high-volume business correspondence. Their primary benefit is the efficient peel-and-seal closure combined with a transparent window, which eliminates the need to manually address envelopes, though users should ensure their document print margins align correctly with the window position before finalizing bulk mailings.

FAQs

What size paper fits best in these envelopes?

These C5 envelopes are designed to hold an A5 sheet of paper flat, or an A4 sheet folded in half.

What are the exact dimensions of the window?

The window measures 45mm by 90mm.

Does this envelope require moisture to seal?

No, these are peel-and-seal envelopes, meaning they use a pressure-sensitive adhesive strip rather than a gummed edge.

Are these envelopes suitable for laser printers?

While the envelopes themselves are not meant to be fed through a printer, they are designed to house documents printed on standard office equipment.

Is the paper thick enough to see through?

The 100gsm paper is high-quality and opaque, providing excellent privacy for standard business documentation.

How many envelopes are in one pack?

Each pack contains 500 individual envelopes.

Troubleshooting

Address is not visible through the window

Verify that your document margins are set to align with the window position (57mm in from the left, 20mm up from the bottom).

Peel-and-seal strip is not sticking properly

Ensure the sealing area is free from paper dust and perform a firm, uniform press across the entire strip; check storage humidity levels.

Envelope jamming in automated insertion machine

Fan the stack of envelopes before loading to ensure static electricity is dissipated and individual pieces are separated.

Pros and Cons

Pros

  • Efficient peel-and-seal mechanism saves time during large mail-outs
  • Pre-cut window reduces labor costs associated with manual addressing
  • Durable 100gsm weight provides a professional feel and prevents transparency
  • Standardized dimensions ensure compatibility with most business printing software

Cons

  • Window position is fixed, requiring specific document margin adjustment
  • Peel-and-seal adhesive has a limited shelf life if stored in humid conditions
  • Not intended for heavy-duty courier shipping, strictly for standard postal mail

Setup, Compatibility & Care

To achieve the best results, ensure your document template accounts for the window coordinates: 57mm from the left edge and 20mm up from the bottom corner. When sealing, ensure the peel-and-seal strip is pressed firmly across the full width to create a complete bond. Store the envelopes in a cool, dry place away from direct sunlight to maintain the integrity of the adhesive and the brightness of the white paper. Keep them in their original box to prevent the corners from curling or the paper from absorbing atmospheric moisture, which could affect machine insertion processes.
