ABSTRACT:
A tear-strip opening envelope apparatus is provided with a tear-strip opening feature for facilitated closing, sealing, opening and emptying thereof. A tear-strip is located on each of two panels enclosing the sides of the envelope, with each of the tear-strips attachably overlying the other in close alignment, upon sealing of the envelope. The attached aligned tear-strips create a single multi-ply tear-strip assembly which facilitates the opening and emptying of the envelope. Opening of the tear-strip opening envelope apparatus is accomplished by pulling the reinforced multi-ply tear-strip member, at an end thereof, across the tear-strip opening envelope.
