FILM PACKAGE Russian patent published in 2013 - IPC B65D75/28 

FIELD: packing industry.

SUBSTANCE: invention relates to a film package for food products. A film package for soft food products comprises a film (30) that forms a reservoir (13) and has a thermally welded layer (38), and a film (32) that creates a cover and is connected by thermal welding with the thermally welded layer (38) of the reservoir-forming film (30) and closing the reservoir (13) with the cover (16, 20), besides, the reservoir-forming film (30) and the cover-forming film (32) are multi-layer, and one of the layers represents an aluminium foil (34), which is possibly equipped with a coating on one side, and if it is printed, it is also equipped with a coating on top of the print, at the same time the aluminium foil (34) of the reservoir-forming film (30) and the cover-forming film (32) has thickness from 5 to 15 mcm and is coated with an ionomer (36) with specific weight per unit of area making 1-10 g/m², at the same time the thermally welded layer (38) is arranged on the ionomer layer (36) of the reservoir-forming film (30), and a) the ionomer (36), possibly coated with a thermally welded varnish (38), is arranged on the aluminium foil (34) of the cover-forming film (32), and the anti-corrosion layer (40), made of, when appropriate, from a polymer, is arranged on the other side of the aluminium foil (34), or b) the aluminium foil (34) of the cover-forming film (32) is coated with the thermally welded varnish (38) on the welded base, and the ionomer layer (36), covered when appropriate with the thermally welded varnish (38), is arranged on the other side of the aluminium foil (34).

EFFECT: production of a thin film resistant to mechanical actions and protecting foil against corrosion.
