FIELD: packaging industry.
SUBSTANCE: material for induction heat sealing for packaging liquid products comprises a layer of paper or cardboard, outer liquid-impermeable heat sealable polymer layers based on polyolefins, and a vapour-deposited metal coating covering the inner side of the layer of paper or cardboard, sensitive to induction heating.
EFFECT: invention enables creating the packaging material not containing aluminium foil for aseptic packaging of liquid products, which provides sufficient barrier properties of packaging containers for long-term aseptic storage under ambient conditions, which can be sealed using induction welding based on the mounted equipment for filling and sealing the packages.
