The paper analyzes the topicality of secondary polymer materials usage in new products. It considers the main stages of secondary polymers processing. Three main groups of recycling processes are singled out, i.e. preparatory, shape-generating, and auxiliary. The paper highlights special perspectives of the coextrusion with further blowing technology usage. The calculation of multilayer preform adhesion for different loading conditions is done. The paper researches the deflected mode in the process of blowing the preform, consisting of three layers; two outside layers consist of primary polymer, and the inside layer is the polymer received during the recycling. While modelling the material of each preform layer, a viscous-elastic model of the material is used; this model allows identifying the deflected mode within each layer and between the layers, taking into account the change of polymer viscosity in the nonuniform cooling conditions. The dependencies of deformation rate intensity on blowing pressure for each of three layers of a multilayer product are calculated.
