A small container comprising as major components a generally rectangular frontside sheet A and a generally rectangular backside sheet B, both consisting of thermoplastic polymer material and each having an inner face and an outer face, wherein A and B are joined to each other at three edges ( 1,2,3 ) either directly or through connecting pieces of sheet material, while at least a part of a fourth edge ( 4 A) and a corresponding part of an edge ( 4 B) are not joined so as to serve as a mouthpiece characterised in that A and B are each a laminate consisting of at least two film layers wherein the film layer ( 5 ) which forms the inner face of the laminate has a corrugated waved shape with the waves extending generally parallel to an edge of the sheet, the other film layer(s) ( 6 ) are flat; and the direction ( 7 ) in which the waves in the film layer which forms the inner face of the sheet A extend is generally perpendicular to the direction ( 8 ) in which the waves in the film layer which forms the inner face of sheet B extend.
