FIELD: packaging industry.
SUBSTANCE: invention can be used for packaging food products and pharmaceutical preparations. Multilayer packaging film includes an outer layer, a passive oxygen barrier layer and an active oxygen scavenging layer. Outer layer is made of thermoplastic polymer. Active oxygen scavenging layer contains polyolefin or polystyrene, as well as polyterpene resin and transition metal catalyst. Catalyst contains a transition metal and a counterion selected from chloride, acetate, acetylacetonate, propionate, oleate, stearate, palmitate, 2-ethylhexanoate, octanoate, neodecanoate or naphthenate. Passive oxygen barrier layer is sandwiched between two layers of active oxygen acceptance.
EFFECT: improved barrier properties of the multilayer film when exposed to moisture and temperature, as well as reduced turbidity of the film.
