The #11 office envelope can be used as regular office envelopes to send invoices, letters, statements, reports, newsletters, and others. Slightly bigger than #10 envelopes, these #11 window envelopes offer a bigger enclosure space for carrying a heavier stack of documents. These envelopes are made from standard 24lb white stock paper and they come with a single poly-film, transparent window. The transparent window eliminates the need to write or print the receiver’s address, which greatly reduces mailing effort. The envelopes have two diagonal seams and a V-shaped flap. These envelopes are printer-compatible and machine insertable. The flaps come with moisture-sensitive gum.
Customers can even have their black and white company logos pre-printed on them for no extra cost. The #11 window envelope size is perfect for multiple pages of A4 documents. It measures 4.5x 10.375 inches and it offers an enclosure real estate of 4.25 x 10.125 inches. These envelopes have a bright white color and they have a smooth wove finish.
