FAQs

What size document fits in these envelopes?

These C5 envelopes are designed to hold A5 paper or A4 paper folded in half.

Does the window size accommodate all address formats?

The window measures 100x45mm, which fits standard address blocks if positioned correctly at the top of your document.

Are these envelopes suitable for sending through high-speed mailing machines?

While they can be used manually with great speed, check your specific machine's manual to ensure it supports the 100gsm weight and specific window placement.

How many envelopes are in one box?

Each pack contains 500 individual white envelopes.

Is the envelope paper transparent?

No, the envelopes feature a blue opaque interior which obscures the contents to provide added document security.

Troubleshooting

Peel-and-seal strip does not adhere properly

Ensure there is no paper dust or debris on the adhesive strip and press firmly across the entire flap once closed.

Address is not visible through the window

Check your document folding method; the address must be printed in the top-right or top-center area of the document to align with the 100x45mm window.

Pros and Cons

Pros

  • Fast peel-and-seal strip saves significant time during bulk mailings
  • Blue interior pattern ensures sensitive financial or personal data remains private
  • Pre-cut window reduces the need for manual addressing
  • Bulk pack of 500 provides excellent value for high-volume office use

Cons

  • Not suitable for heavy-duty shipping or mailing bulky items
  • C5 size is restricted to A5 documents or folded A4 sheets
  • Paper weight of 100gsm is standard and may not feel as premium as heavier stock

Setup, Compatibility & Care

To ensure proper function, always align your documents so that the recipient address falls within the 100x45mm window dimensions. For bulk mailings, ensure your printer layout is configured to print the address area on the top third of the document to match the C5 pocket orientation. Store the envelopes in their original packaging to prevent dust buildup on the adhesive strip, which can reduce its tackiness over time. Avoid exposing the box to extreme temperatures or high humidity, as this may prematurely activate the seal or cause the paper to warp.
