FIELD: chemistry.
SUBSTANCE: invention relates to film structures, in particular to coating films and packaged products made from them. Layered film based on polypropylene, suitable for use as a coating film, comprises an outer film, a barrier layer and a welded layer. Coating film is characterized by a common composition containing large amounts of polyolefin-based polymers and polypropylene-based polymers, so that the material can be efficiently processed during recycling of polypropylene.
EFFECT: enabling preservation of properties required for suitable aging of sterilization and pasteurisation processes and obtaining a high-quality packaged product.
