The perforated and non-perforated sections form together an inner chamber of the bag in the form of tube-like base element with the compound passing along the length of the shell in one of the non-perforated sections. Each perforated section is located adjacent to two non-perforated sections. The opening of the tube-like base element is closed by compound with the first and second sections, each of which comprises at least four layers of the receiving element (12). In the first section sub-section two inner layers of the compound are made of material of the first perforated section, and in the second section sub-section two inner layers of compound are made of material of the second perforated section.
