Paper Options That Deliver Quality

For #9 envelopes, Printin Budget uses one reliable and professional choice:

  • 70 lb. Opaque Smooth White – Strong and smooth, perfect for everyday business mail.

This paper is trusted across the U.S. for its balance of durability and clean appearance. The smooth surface allows sharp, detailed printing so your logo, text, or graphics look professional on every envelope. Its weight provides strength while still being light enough for easy mailing. The opaque design also protects privacy by preventing contents from showing through.

Whether you are mailing invoices, reply slips, or marketing materials, our premium is 70 lb. stock ensures your envelopes reflect quality and make a positive impression.
