Extended Product Information

FAQs

What size paper fits inside a C6 envelope?

A C6 envelope is designed to hold an A4 sheet folded into quarters or an A5 sheet folded in half.

Are these envelopes eco-friendly?

Yes, they are PEFC certified and fully recyclable.

Can I use these in an inkjet printer?

Yes, they are compatible with most standard inkjet and laser printers.

How does the security pattern work?

The interior is printed with a complex blue pattern that obscures text, making it difficult for prying eyes to read through the envelope paper.

Do I need to lick these to seal them?

No, these are self-seal envelopes that rely on a pressure-sensitive adhesive strip.

What is the weight of the paper?

These envelopes are made from 90gsm paper, which is a standard, durable weight for professional mailing.

Troubleshooting

Printer jamming during use

Ensure the envelope is fed into the tray flap-side up or as directed by your printer manual, and check that the paper guides are not too tight.

Envelope seal is weak

Apply firm, even pressure across the entire length of the self-seal strip for several seconds to activate the adhesive properly.

Pros and Cons

Pros

  • High-security interior pattern ensures document confidentiality
  • Self-seal closure is convenient and mess-free
  • Environmentally conscious with PEFC certification and full recyclability
  • Compatible with most standard printing equipment

Cons

  • Fixed C6 size limits document dimensions
  • Self-seal adhesive strip may have a limited shelf life if stored in extreme humidity
  • Requires precise folding of A4 documents to fit

Setup, Compatibility & Care

To ensure optimal performance, store these envelopes in a cool, dry place to prevent the self-seal adhesive from drying out or prematurely activating. When printing, ensure your software is set to 'Envelope C6' and that the paper guides in your printer tray are adjusted snugly against the sides of the envelope to prevent misalignment. Do not attempt to run the envelopes through a printer if they have already been sealed or if the backing strip has been removed.
