Booklet Envelopes – 9″ x 12″ and 10″ x 13″

Booklet envelopes are an excellent choice for mailing documents that must remain flat. Available in 9″ x 12″ and 10″ x 13″ sizes, these envelopes are perfect for sending catalogs, reports, brochures, presentation folders, and important documents without folding.

Easy to Use with Multiple Seal Options

Featuring an open-side design (opening on the long edge), booklet envelopes allow for easy insertion and removal of contents—ideal for thicker or multi-page materials. Constructed from durable white 24# or 28# white wove paper, these envelopes are built to handle bulkier content while maintaining a polished look.

Choose from dry gum (moisture-activated) or peel & seal (self-seal) closures to suit your mailing preferences. Both options ensure a secure seal—whether you need traditional mailing methods or quick, mess-free sealing for high-volume jobs.
