Abstract: The purpose of this research is to know the strength, flexibility and maximum hardness of plastic waste after pressing of HDPE, PET/PETE and PP type with bending test. Furthermore, the specimen is made referring to ASTM 6272 D and the testing is carried out with the specified measurement. The results show that the strongest recycled plastic with the highest bending level is obtained from the composition of 50% HDPE, 20% PET/PETE and 30% PP, with maximum power of 52.9 N/mm2 and 137.74 Kg/mm2 . In addition, the biggest flexibility strength is plastic with composition 50% HDPE, 20% PET/PETE and 30% PP with strength value of 9.53 N/mm2 . As for hardness value, it reaches 12.76 Kg/mm2 . Because the plastic in used is recycled Plastic, the resulting product cannot be used for food and beverage container. However, it can be used for flower pot and pencil case.
