FIELD: packaging industry.
SUBSTANCE: work piece is provided with two panel sections from flexible packaging material, which adjoin each other. Besides, panel sections are limited by rim and interconnected along the rim length to form closed compartment. Besides the container work piece has the first end section, which is implemented so that at least one angular section of the container work piece could be bent inside to form the bottom surface as container work piece is filled up. The claimed group of inventions is also referred to a method of container production from the above-mentioned work piece. The claimed group of inventions provides for producing cardboard work piece, which can be made and delivered in the form of roll being wound-up equally along the whole its length. At the same time equal welding parametres are involved along the connection ensuring reliable joining.
EFFECT: group of inventions ensuring work piece production using existing but slightly modified equipment, low cost of work piece production and low container price.
