Security Envelopes


Order Security Envelopes and get FREE shipping! Protect your recipient's privacy with envelopes featuring an inside security tint. Great for mailing checks, invoices, tax information, medical reports or any other sensitive information. Available in a variety of sizes including #6 3/4, 3 5/8 x 8 5/8, #9, #10, 6x9, 9x12 and 10x13. Display pre-printed information through a Security Window Envelope, available in double or single window styles.

We can print addresses, logos or any text onto select security window envelopes. See a PDF proof before printing. Pick from products with a standard gum seal or a Peel and Seal adhesive strip. We also offer FDIC security tinted products. The pattern darkens paper stock so the contents of the envelope remain hidden from view. Use these products to mail private information that cannot be compromised.
