Product Information

Full details

The Q-Connect C5 Window Self-Seal envelopes are ideal for office administrators, small business owners, and individuals who frequently mail A5 documents or folded A4 letters. These 90gsm envelopes offer the significant benefit of a self-seal adhesive flap, which eliminates the need for moisture or additional glue, streamlining high-volume mailings. However, users should note that as a standard-weight paper product, they provide minimal protection against heavy-duty impacts and are designed primarily for standard postal services.

FAQs

What document size fits inside these envelopes?

These C5 envelopes are designed for A5 documents (unfolded) or A4 documents (folded once in half).

Do I need to lick the seal to close it?

No, this is a self-seal envelope. Simply peel the protective strip (if applicable) or press the pre-glued flap down to seal.

Is the paper heavy enough to keep documents private?

The 90gsm paper provides a standard level of opacity suitable for general business documents.

Are these envelopes suitable for laser printers?

It is recommended to print your letter on standard paper and insert it into the envelope, rather than feeding the envelope itself into a printer.

How many envelopes come in a pack?

Each pack contains 150 envelopes.

Troubleshooting

The self-seal flap is not sticking firmly.

Ensure the adhesive surface is free from dust or paper fibers and apply firm, even pressure along the entire width of the flap.

The recipient address is not visible through the window.

Verify that your document folding technique matches the window position; try adjusting the top margin of your document template by a few millimeters.

Envelope paper appears creased after printing.

The envelope itself should not be fed through a printer; print your document first, fold it, and then insert it into the envelope.

Pros and Cons

Pros

  • Self-seal design saves time during mass mailings
  • Clear window eliminates repetitive addressing tasks
  • Professional white finish suits corporate communication
  • Optimized size for standard A4 and A5 document formats

Cons

  • Window size is fixed and may not align with all custom document templates
  • Standard 90gsm weight is not intended for heavy-duty shipping
  • Not suitable for bulky items or thick booklets

Setup, Compatibility & Care

For optimal use, store the envelopes in a cool, dry place to prevent the adhesive strip from prematurely drying out or sticking to other envelopes. When inserting documents, ensure the content is flat to prevent bunching, which could obscure the address window. These envelopes are compatible with all standard domestic and international postal services. If you are printing your documents, check your printer software settings to ensure the return address and recipient address fields align with the window dimensions of a standard C5 envelope.
