Implementation of the products from recycled polyethylene terephtalate (pPET) bottles in the Latvian market should be promoted. In order to achieve this goal, secondary blends, obtained from PET base material as well as polyolefine closures and labels (pCL), are investigated. The effect of the pCL content as well as compatibilizer content on the quasistatic short term tensile and flexural properties, flexural creep characteristics, impact strength as well as calorimetric, thermomechanical and rheological properties have been investigated. Results of the investigation show that properties of the thermoplastic composites are sufficient to use them according to the specific needs of the customer.
