The aim of study was to compare properties of pure and recycled polyethylene blends with different filler content. Talc was compounded with two types of recyclable polyethylene: rLDPE and rLLDPE using a twin-screw extruder. The composites were blown moulded and the effect of the filler content on the end-use properties of blown films were investigated. Selected properties such as: mechanical, thermal and structure of composites were compared to virgin and recycled LDPE films. The effect of talc on crystallization and mechanical properties composites based on the recycled polymers as nucleating agent or/and inorganic filler were studied. It was shown that 30 wt. % amount of talc addition improved crystallization of 70L/30LL/30T. The degree of crystallinity improvement for the tensile strength, which were corresponding to crystallization analysis, so talc can play a role of heterogenous nucleation agent on PE and can be an effective filler to modify the PE matrix. The produced film is characterized by very good usable properties and satin-paper grip. The recycled composites can be used as a packaging material to group packs for ease of handling or tertiary packaging for ease of transport.
