    The present invention provides a method of separation of individual components from a composite packaging material, wherein the composite packaging material is crushed, combined with an organic separation agent in weight ratio material:agent 1:5 to 1:10, the resulting mixture is heated to a temperature in the range of 40 to 100 °C and left to react at stirring until separation of the individual components occurs, and the individual components are then isolated by a method based on their different specific weights. The organic separation agent is a mixture of crude oil fraction with distillation curve from 50-200 °C with an organic solvent selected from toluene, xylene, acetone, N-methyl pyrrolidone, N-ethyl pyrrolidone and formic acid.
