The 5 Star Office Mail Machine Envelopes are designed for high-volume mailing environments, making them ideal for administrative professionals and offices that rely on automated insertion equipment for efficient document processing. These C5-sized envelopes feature a precise window design and a professional 90gsm weight, providing both functionality and a clean look; however, the traditional gummed seal requires a wetting agent or compatible mailing machine dampener, lacking the convenience of self-seal alternatives.

The window measures 100x40mm.
Yes, they are PEFC certified and use biodegradable window film.
No, this product uses a traditional gummed seal that must be wetted to activate.
There are 500 envelopes per box.
Yes, C5 envelopes are designed to fit an A4 sheet folded in half.
These envelopes are constructed from 90gsm white paper.
Check the machine feed tray for debris and ensure the paper stack is not too high or fanned too tightly.
Ensure the sealing mechanism on your mail machine is dispensing enough water, or check that the gummed surface is free of paper dust.
To maximize performance, ensure your insertion machine is calibrated for the C5 format and the specific weight of 90gsm paper. Keep the envelopes in a cool, dry environment; humidity can cause the gummed seals to activate prematurely or the paper to curl. When loading, ensure the envelopes are fanned out slightly to prevent static buildup, which can cause multiple envelopes to feed at once. If you are using these with manual insertion, ensure the moisture level applied to the gummed flap is consistent; too much water can warp the paper, while too little will result in a weak seal.
