Abstract (en)
[origin: EP1468931A1] An object of the present invention is to provide a packaging bag capable of being realized only by a rather simple processing and opened easily by hand without deteriorating the sealing strength of the packaging bag and the strength of the packaging bag itself and without suffering from the possibility of peeling-off of the sealed portion during a distribution stage. The present invention relates to a packaging bag formed by adhering two sheets of front and rear side films mutually at peripheral parts to seal an inside thereof, wherein the front side film has, in one direction, linearly cuttable property that is larger than linearly cuttable property in any direction of the rear side film, and a processed portion capable of starting cutting of the front side film along the one direction is provided at a part of the peripheral parts that intersects with the one direction. <IMAGE>
