1. A film comprising at least one alginate membrane, consisting of a carrier film that absorbs liquid, and at least one alginate membrane, wherein the carrier film is a carrier that absorbs liquid； the alginate membrane is a membrane consisting of a hydrogel complex and having a mesh structure formed by a cross-linking reaction occurring between at least one layer of alginate solution deposited on at least one surface of the carrier film, and of at least one layer of an aqueous salt solution, coated on at least one surface of the carrier film； the alginate solution contains some weight percent alginate, such as sodium alginate or potassium alginate, while the aqueous salt solution contains some weight percent of divalent metal ions； an alginate solution layer and an aqueous salt solution layer are applied to the surface of the carrier film by two separate continuous coating processes； the crosslinking reaction between the alginate contained in the alginate solution and the divalent metal ions contained in the aqueous salt solution, carried out on or inside the surface of the carrier film, leads to the formation of an alginate membrane. 2. The film according to claim 1, characterized in that the carrier film is a non-woven material, a textile product, a film of porous spongy material or a plastic film. The film according to claim 1, characterized in that the carrier film is made of synthetic fibers, natural fibers, high molecular weight polymers or their1. Пленка, содержащая по меньшей мере одну альгинатную мембрану, состоящая из пленки-носителя, которая поглощает жидкость, и по меньшей мере одной альгинатной мембраны, при этом пленка-носитель является носителем, который поглощает жидкость；альгинатная мембрана является мембраной, состоящей из гидрогельного комплекса и имеющей сетчатую структуру, образованной посредством реакции поперечного сшивания, происходящей между по меньшей мере одним слоем альгинатного раствора, нанесенным по меньшей мере на одну поверхность пл
