The Postmaster 162x238mm High Window Envelopes are ideal for businesses and administrative offices that rely on automated mailing machines to handle high-volume correspondence. These envelopes provide the benefit of smooth, jam-free operation thanks to their internal side seam construction and precise window placement, though users should note that the gummed seal requires manual wetting rather than being self-adhesive.

No, these envelopes feature a traditional gummed closure that requires moisture to seal.
The envelopes are constructed from 90gsm white paper.
Yes, they are compatible with most standard laser and inkjet printers, provided your printer settings are adjusted to the envelope size.
The window measures 40mm high by 100mm wide.
Each box contains 500 individual envelopes.
Ensure the side guides of your machine are set exactly to 162mm wide and check that the internal flaps are not overlapping.
Verify that your machine's moistening sponge is saturated and positioned correctly to contact the gummed strip evenly.
Keep the internal cardboard inserts inside the box and ensure the lid is closed tightly to maintain structural pressure.
To ensure the best results, keep the envelopes in their original box with the internal inserts until you are ready to load them into your machine. This prevents environmental moisture from causing the gummed flaps to curl or prematurely activate.
