Abstract

An easy-to-unseal packaging bag capable of being realized only by a rather simple processing without lowering the strength of the sealed portion of the packaging bag and the strength of the packaging bag itself and easily unsealed by hand without providing the possibility of peeling-off of the sealed portion in a distribution stage, wherein two sheets of front and rear side films are sealingly stuck to each other at the peripheral parts thereof, the linear cuttability of the front side film in one direction is larger than that of the rear side film in either direction, and a processing part capable of starting the cutting of the front side film along one direction is provided at a part of the peripheral parts intersecting the one direction.
