Window Envelopes

Business correspondence, billing, direct mail, checks, statements, invitations, and larger document mailings all benefit from a wide range of window placements and envelope styles. JAM Paper window envelopes include single-window, double-window, full-face, all-purpose, right-window, vertical-window, and bottom-left-window options for different document layouts. Available sizes include the standard #10 at 4 1/8 x 9 1/2 inches and A7 at 5 1/4 x 7 1/4 inches, along with larger 9 x 12-inch and 10 x 13-inch options and several other sizes in between.

Paper weights include 24 lb, 28 lb, 30 lb, 32 lb, and 68 lb, with materials and finishes suited to both everyday office mail and more distinctive correspondence. Choices include standard white, security-tinted white, brown kraft, grocery bag kraft, natural linen, white linen, cougar white wove, birch woodgrain, translucent paper, and solid colors. Closure options include standard gum, peel & seal, redi seal, and simple seal, providing practical choices for routine correspondence, recurring billing, customer communications, and higher-volume mailing programs.

Clear windows reduce separate labeling steps by allowing printed addresses, sender information, invoice details, or other content to remain visible from the enclosed document. Standard business window envelopes work well for folded letters and statements, while full-face and larger styles can display invitations, artwork, branded inserts, reports, and professional materials. This broad collection gives businesses, schools, nonprofits, healthcare offices, financial organizations, and administrative teams flexible window mailers for everyday office use, direct mail, billing workflows, and specialized correspondence.
