FAQs

What size paper fits in a C5 envelope?

A C5 envelope is designed to hold an A5 sheet unfolded, or an A4 sheet folded in half.

Can I run these envelopes through a printer?

While these are designed for manual use, you can feed them through most inkjet or laser printers if your printer supports custom envelope sizes, but use caution to avoid jamming.

Is the paper transparent?

The paper is 80gsm, which is standard office weight. It is opaque enough for normal text, but dark backgrounds or heavy ink usage may be slightly visible through the paper.

What are the exact window dimensions?

The window measures 45 x 90mm.

How do I seal the envelope correctly?

Peel away the paper strip covering the adhesive strip and press the flap firmly down onto the envelope body.

Troubleshooting

Address not visible in window

Check your printer margins or document layout to ensure the address is positioned 57mm from the left edge and 20mm from the bottom.

Adhesive strip is not sticking

Ensure the surface of the envelope is clean and free of dust, and apply firm, consistent pressure along the length of the flap.

Pros and Cons

Pros

  • Window feature eliminates the need for manual addressing labels
  • Peel-and-seal closure is fast and hygienic to use
  • Standardized sizing ensures compatibility with most printers and documents
  • Clean, professional white paper finish

Cons

  • Pack size of 25 is small for high-volume business mailing
  • 80gsm weight is standard and may show heavy ink bleed-through if using markers
  • Not intended for heavy-duty catalog or booklet shipping

Setup, Compatibility & Care

To ensure optimal results, align your document template so the address falls within the 45 x 90mm window frame. When storing, keep these envelopes in a cool, dry place to prevent the peel-and-seal adhesive from prematurely degrading due to humidity. Avoid bending the envelopes during storage, as creases may interfere with the clarity of the address window during automated postal scanning. When using, press firmly along the seal strip for at least three seconds to ensure a permanent bond.
