FIELD: instrument engineering.
SUBSTANCE: invention relates to a bag having a side wall made of at least two layers, closed respectively by means of a longitudinal glue line to form a sleeve, two end ends closing the bag at the ends of the folding bottoms and the filling opening for filling with the material to be loaded, this side wall having at least one paper layer, and the specified at least one paper layer at least predominantly determines the permissible load from the loaded weight and the mechanical stability of the bag, consumer properties of the bag are improved due to the fact that the side wall on its outer side has a layer of polymer film with a thickness of 60 mcm or less, which surrounds the specified at least one paper layer, protecting it from moisture, and in the region of overlapping ends, there are bonding places (K) between which there are channels (Z) for removing air, and in the region of overlapping ends the film has no perforations.
EFFECT: improved consumer properties of the bag.
