The present disclosure provides a plastic pouch or bag comprising a front wall, a rear wall, an opening and a bottom. The front wall and/or the rear wall have at least three layers, wherein the at least three-layered front wall and/or the at least three-layered rear wall comprise one first layer (inner layer), at least one second layer (intermediate layer) and one third layer (outer layer). The first layer faces the inside of the pouch or bag in relation to the second layer and/or forms the inner side, wherein the at least one second layer is arranged between the first and third layer and comprises or consists of a plastic film, and wherein the third layer faces the outside of the pouch or bag in relation to the second layer and/or forms the outer side. The at least one second layer comprises a plurality of riffled or folded strip-shaped longitudinal areas at a distance from each other, and the at least one second layer is connected to the first and/or third layer by means of welded and/or glued seams, which run transverse to the riffled or folded strip-shaped longitudinal areas.
