Unlike booklet envelopes, catalog envelopes have an opening on one of the shorter sides. They are perfect for sending unfolded documents that are printed in portrait mode. These 9 X 12 catalog envelopes are often used to send agreement copies, magazines, brochures, and other documents that cannot be folded. This particular envelope is made from 28 lb white sulphite paper. Much stronger than 24lb paper envelopes, this envelope’s enhanced durability makes them suited to carry a heavier load. These envelopes have a peel & seal closure system that requires no moisture. The envelopes have a blank, windowless design with a rectangular flap and two parallel seams.
This 9X12 white open end peel & seal 28lb envelope measures 9 X 12 inches and it allows a maximum insert size of 8.75 x 11.5 inches. Slightly more expensive than 24 lbs 9 X 12 envelopes, these come with enhanced durability and requires less sealing effort. Customers get the option to customize these envelopes by adding logos and business information.
