When there is a need for sending stacks of unfolded business documents, there is no denying the convenience of a 9 X 12 envelope. These envelopes are specially designed to carry unfolded stacks of paper sheets. The 9 X 12 Brown booklet envelope is made from 28 lb brown Kraft paper. These envelopes have a formal brown color, which makes them perfect for business mails. The envelopes have a simple style with a rectangular flap and two parallel seams. As a bonus, customers can get a black and white logo printed on these for free when ordering imprinted envelopes. The envelopes have a traditional gummed seal.
These brown 9 X 12 are more durable than 24 lbs white booklet envelopes. This is why they are often used to send heavier stacks of documents. These envelopes have enough space for an unfolded 8.75 x 11.5 inch sheet. This means it can easily hold an unfolded A4 sheet.
