FIELD: physics.
SUBSTANCE: invention pertains to a foil, meant to be used mainly for carrying catalytic active materials for neutralisation or reduction of toxicity of waste gases. Description is given of the foil (1), which has at least, one groove (2), which is tone in the inner part (3) of the foil sheet (1) and at least, partially borders the microprofile structure of the foil (1), which protrudes from the profile structure (5) of its surface. At least one groove (2) has at least one cut (7) on at least one of its end parts (6). Description is also given of a carrier (21) meant for neutralisation or reduction of toxicity of waste gases of a component, made from a number of at least partially profiled sheets of foil (1), which are gathered in a packet and/or rolled in such a way that they provide for passage of a flowing medium through the carrier, and at least one of which is mate in the form of sheet of the foil (1) described here above (fig.1). Description is also given of the use of carrier (21) in a system of releasing waste gases (35).
EFFECT: prevention of crack propagation from bordering microprofile structures of agroove in a foil and longer life service of the carrier.
