#10 Business Envelopes

These #10 envelopes suit offices, schools and mailrooms that send standard letters, invoices or statements in high volume. The white sulphite stock provides a clean, professional appearance for everyday correspondence. A box of 500 keeps supply rooms stocked for extended periods.

Recycled Compostable Materials

Each envelope contains 30% post-consumer recycled fibre and features a compostable window film. SFI certification confirms responsible forest sourcing, while the acid-free sulphite stock resists yellowing to protect archived documents. The construction supports standard automated inserting equipment.

92% Brightness Window

The 92% brightness white surface improves readability of printed addresses and barcodes through the window. Acid-free paper helps maintain legibility over time for records that must be retained. Compostable window material allows the entire envelope to enter organic waste streams where facilities exist.

Questions about this item

Will the 30% post-consumer recycled content affect how the envelopes hold up in high-volume mailing equipment?

The envelopes use white sulphite stock rated at 92% brightness and are acid free, so they feed reliably through standard inserters and postage meters without jamming.

Do the compostable windows create any noticeable odour or heat build-up when boxes sit in a warm mailroom all day?

The window film is designed to break down in composting conditions, not from ambient heat, so stored boxes remain odour-free and dimensionally stable.

What printer or copier settings are needed so the address shows cleanly through the window?

Any standard laser or inkjet printer works; simply align the address block to the 1-1/8" x 4-1/2" window area on a #10 envelope template.
