Full details

These 90gsm envelopes offer a professional, crisp appearance with a convenient self-seal closure that eliminates the need for moisture or adhesive tape. While these envelopes provide excellent utility for standard correspondence, they are intended for light-duty mailing and may not be suitable for items requiring heavy-duty protection or padding.

Extended Product Information

FAQs

Will these envelopes fit an A4 sheet unfolded?

No, an A4 sheet must be folded in half to fit comfortably inside a C5 envelope.

Does this envelope require wetting?

No, this is a self-seal envelope, which uses a pressure-sensitive adhesive strip.

What is the weight of the paper?

The envelopes are made from 90gsm paper, which is standard for professional office correspondence.

Are these envelopes opaque?

They are made of standard white 90gsm paper. While they provide good coverage, highly detailed or dark content on the enclosed document may be slightly visible.

How many envelopes come in a pack?

Each pack contains 500 envelopes.

Can I put these through a printer?

Yes, most standard printers can accommodate these envelopes. Ensure your printer settings are adjusted to the correct envelope size.

Troubleshooting

Envelope seal not sticking properly

Ensure the adhesive strip is free of paper debris or dust. Apply firmer, consistent pressure across the entire flap width.

Difficulty inserting documents

Check that the paper is folded crisply and fits the width of the envelope. If the document is too thick, consider using a larger envelope style.

Pros and Cons

Pros

  • Efficient self-seal closure saves time during bulk mailings
  • Perfectly sized for common A4 and A5 document sizes
  • Generous 500-pack provides excellent value and convenience
  • Sturdy 90gsm paper offers a professional presentation

Cons

  • Not padded, so not suitable for shipping fragile items
  • Standard paper weight may show through if contents are highly contrast-heavy
  • Single-use adhesive cannot be easily repositioned once sealed

Setup, Compatibility & Care

To ensure the best results, store the envelopes in a cool, dry place to maintain the integrity of the self-seal adhesive. Exposure to extreme humidity may affect the adhesive strip. When preparing mail, insert documents carefully to avoid catching on the corners. For compatibility, these envelopes work with most standard inkjet or laser printers if you intend to print addresses directly onto the envelope face, though it is recommended to test your printer's paper path first to avoid jams. No specialized maintenance is required; simply keep the box closed when not in use to prevent dust accumulation.
