FIELD: packaging industry.

SUBSTANCE: disclosed stackable package (13) comprises packing bag (17) and a packaged in it fish block (2) frozen in a plate freezing apparatus. Bag (17) is a plastic bag having second outer surface (23), by which package (17) can be laid on pile (32), and opposite first outer surface (6). Rough part (15) of the first external surface (6) contains anti-skid projections (1) protruding from first wall (7) of bag (17). Anti-skid section (26) of second outer surface (23) contains anti-skid material (27), having specially selected fibrous structure and attached to second wall (24) of bag (17). Anti-skid material (27) can slip without skidding with anti-skid projections (1). Bag (17) wear rate lying in range of 0–0.35 is determined by means of appropriate dough during which (at temperature of -20 °C and pressure 11557 Pa) sample of anti-skid section (26) of surface skids on sample (16) of rough surface area, and wear rate is determined by the proportion (of total number) of anti-skid protrusions (1) of said sample (16), damaged during skidding movement.

EFFECT: advantage ensured by the invention consists in the fact that packages (13) may be manually shifted to form another stock without loss of too many anti-skid protrusions (1).
