Estimating the term…
A polymer film is disclosed for effectively smoking and/or drying products packed therein, which are to be smoked and/or air dried, in particular, smoked cheeses, smoked, uncooked smoked, and air-and-sunshine dried sausages, meat and fish products. This single-layer film is produced on the base matrix of an aliphatic polyamide and/or copolyamide and/or terpolyamide and contains 4.0-50.0 wt. % of a hydrophilic compound which is in a highly dispersed state, wherein the hydrophilic compound forms a disperse phase with a linear size of the domain being 0.1-3.0 Sg(m)m in a direction perpendicular to the plane of the film, and either a polymer compound or a low-molecular substance—salt, may be used as such.
A polymer film for food products, comprising a polyamide matrix and a component providing high permeability in respect to smoke substances and/or water vapors, wherein said component is a hydrophilic compound in an amount of 4.5-50.0 wt. %, forming in the polyamide base matrix a highly dispersed phase with a linear domain size of 0.1-3.0 μm in a direction perpendicular to a plane of the film, and capable of mixing with at least 10 wt. % of water.
