The Q-Connect C4 Envelopes (KF02891) are designed for office professionals and businesses that frequently mail bulky documents, catalogues, reports, and brochures. Featuring a generous 25mm expanding gusset and high-quality 120gsm paper, these envelopes provide superior protection for thicker A4 contents; however, users should ensure they are not overstuffed beyond the gusset capacity to maintain structural integrity during transit.

Yes, these are C4 size envelopes specifically designed to hold A4 documents flat.
These envelopes are made from 120gsm paper, which is significantly thicker and more durable than standard office envelopes.
No, these feature a peel and seal closure; you simply remove the protective strip and press to close.
Each pack contains 125 envelopes.
The address window measures 40 x 105mm.
Yes, they meet standard sizing requirements for mailing, though postage rates will depend on the weight and destination.
Ensure the envelope flap and body are free from paper dust and that the strip has not been exposed to extreme moisture.
Verify that the document stack does not exceed the 25mm thickness; if it does, consider splitting the mailing into two separate envelopes.
Check your document print template settings to ensure the address block is positioned within the standard top-left area matching the 40 x 105mm window.
To use these envelopes, ensure your A4 documents are aligned correctly to be visible through the 40 x 105mm window. When preparing your mail, fold the gusset edges inward before placing the documents inside to ensure a smooth seal. Always store the envelopes in a cool, dry place to prevent the peel-and-seal adhesive strip from prematurely drying out or activating due to high humidity. Avoid exposing the box to direct sunlight for extended periods to maintain the crisp white finish of the paper.
