Blank envelopes are the foundation of any mailing program. No pre-printed return address, no logo, no design on the face. Just quality stock, a reliable closure, and a clean surface ready for whatever your operation requires: printed in-house on a laser or inkjet, addressed by hand, labeled on the fly, or sent as-is for personal correspondence. At Business Envelopes, our blank envelope catalog spans every major commercial size from #6 3/4 through 10 x 15, in white, brown kraft, tinted security, and colored stock, with gum flap, peel-and-seal, self-seal, and clasp closures. Free ground shipping on every order across the contiguous 48 states. No minimums. Same or next day production on all blank stock.
Bulk Envelopes: Why Blank Stock Ships Fastest
Blank stock has no production queue. There's no artwork to proof, no print run to schedule, no drying time between production and packaging. When you order blank envelopes, the order goes directly to fulfillment. Most blank stock ships same or next business day. For offices, print shops, nonprofits, and businesses that need to restock quickly or maintain a standing inventory without waiting for a print run, blank stock is the reliable choice. It also gives you full flexibility on addressing, whether that's a laser printer running variable-data addresses, an inkjet running a merge file, a thermal label printer, or handwriting on individual pieces.
Buying in bulk reduces the per-unit cost significantly. The price per envelope drops with each quantity tier, and since blank stock has a long shelf life when stored flat and dry, ordering in volume and holding inventory is a practical strategy for any organization that sends regular mailings. Our bulk pricing applies automatically at checkout as quantities increase. No coupon code, no negotiation. The price reflects the volume.
Blank Business Envelopes by Size
#10 Blank Envelopes
The standard commercial letter envelope at 4 1/8 x 9 1/2 inches. The most ordered size in the catalog. Available blank in plain white, tinted security, and window formats across gum flap, peel-and-seal, and self-seal closures. Holds an 8.5 x 11 sheet folded into thirds. Qualifies for USPS First-Class letter postage. The default blank business envelope for everyday outgoing correspondence.
#9 Blank Envelopes

6 x 9 Blank Envelopes
Holds an 8.5 x 11 sheet folded in half, 5 x 7 photos, and small booklets without folding. At 6 inches tall, qualifies for USPS letter-rate postage on light contents, which is a meaningful cost advantage over 9 x 12 flat mailers for documents that fold to this size. Available in white booklet, white open-end, brown kraft booklet, brown kraft open-end, and brown kraft clasp formats.
9 x 12 Blank Envelopes
The standard flat-document mailer. Holds an 8.5 x 11 sheet completely flat. No folding, no creasing. Used for contracts, certificates, photos, reports, and any correspondence where document condition on arrival matters. Available blank in white booklet, white open-end, white full-view window, brown kraft booklet, brown kraft clasp, and Tyvek peel-and-seal formats.
10 x 13 Blank Envelopes
One inch larger than the 9 x 12 on each dimension. Fits legal-size 8.5 x 14 sheets flat and accommodates thicker document stacks that push against the walls of a 9 x 12. Available in brown kraft with metal clasp closure. Used by legal offices, accounting firms, and any operation sending thick flat-document mailings.
Tyvek Blank Envelopes
DuPont high-density polyethylene fiber. Tear-proof, puncture-resistant, moisture-resistant. Available blank in 6 x 9, 9 x 12, 10 x 13, and 10 x 15 with Kwik-Tak peel-and-seal closure. At 14 lb, roughly half the weight of kraft, which reduces per-piece postage at volume. For documents where arrival condition is non-negotiable.
Cheap Envelopes That Aren't Cheap in Quality
The search for cheap envelopes is almost always a search for bulk pricing on reliable stock, not a search for the thinnest paper at the lowest cost. A cheap envelope that jams in a printer, activates its gum seal before loading, or tears at the flap during opening costs more to deal with than the money saved per unit. Our blank envelopes are priced competitively because we sell at volume direct to businesses, not at retail markup, and because we don't add unnecessary overhead to the per-unit price. The 24 lb white wove runs clean through laser and inkjet printers. The 28 lb brown kraft holds its shape through postal handling. The gum flap adhesive activates on moisture and holds. These are baseline standards that every envelope in this catalog meets.
The price drops further the more you order, and there's no minimum to start. For volume programs that need pricing on the full scope across multiple sizes, request a bulk quote here. For resellers and corporate accounts with recurring volume, the reseller discount program provides structured pricing without requiring a promotional code on every order. Browse the full size catalog to see every blank format we carry across all sizes, or visit our self-seal envelopes category if moisture-free closure is a requirement.
