White sulphite catalog envelopes

These envelopes are designed for mailing catalogs and documents through standard postal channels. The centre-seam construction and open-end format suit high-volume office mailing operations. Each box contains five hundred units for bulk processing.

28-pound stock with poly window

The 28# white sulphite paper provides a firm feel that protects contents during transit. A clear poly window displays the recipient address without manual labelling. The 92% brightness gives a clean, professional appearance on every piece.

Vellum finish for feed reliability

The vellum surface reduces static and helps envelopes move smoothly through inserting machines and postage meters. Centre seam layout distributes stress evenly when the envelope is filled. SFI certification confirms the paper comes from responsibly managed forests.

How can I confirm the envelopes meet the 92% brightness and SFI-certified white sulphite specification once they arrive?

Check the box label for the 92% brightness rating and SFI certification mark on the white sulphite vellum-finish material.

Does the box of 500 include any sealing strips or moisture-activated glue, or must I supply my own adhesive?
