Investigation of Novel Polymer Composites Based on Recycled Multilayer Combined Packaging Materials

Abstract

Polymer composite based on multilayer combined packaging wastes was prepared and investigated. The composite was made of tetrahedral package wastes, where cardboard part was removed. It was found that obtained composite material has blended polymer matrix that consists of low-density polyethylene, high-density polyethylene and polypropylene. Melting temperature of individual polymers in composite shifts to lower temperatures than that of the initial components. It is the evidence of destruction process or interaction between polymers. The hard particles of aluminum and cellulose are uniformly distributed in the composite. For that reason, these particles do not reduce melt fluidity significantly. The tensile strength and elasticity modulus are higher for the obtained material compared to pure polyethylene. The results show a high potential for the use of the developed composite material.
