Utility mailers offer tough, semi-rigid shipping protection for shipping nonfragile items. Seamless side construction and double-glued bottom flap give added strength and security. Unique folded, top and bottom construction provides extra protection on all four corners. Convenient closure eliminates the need for staples and tape and forms a water-resistant, secure package. Simply peel away liner and seal. Unique tear-tape allows easy opening. Mailers are made with a high percentage of recycled material so they are 100 percent curbside recyclable.
