FIELD: food industry; packaging industry.
SUBSTANCE: invention relates to a tightly closed package containing a product, particularly a food product, for heating in a microwave oven, placed in the said package. Sealed package containing a product has a wall formed of the packing material containing first polymer film (7) and second polymer film (10) which extend along the length of the packing material, while said first polymer film (7) is laminated with second polymer film (10) by means of adhesive layer (16). One of the polymer films has, in its limited area, a layer of heat generating material during exposure to microwave radiation, i.e. heat-generating layer (5), having a susceptor effect.
EFFECT: said heat generating effect, id est the susceptor effect of heat-generating layer (5) is selected for melting, dissolution, softening or weakening of said first polymer film (7) and/or second polymer film (10) in a limited area, as seen, cross-wisely to the packing material in a degreed sufficient for formation of a hole in the limited area.
