          This research is to study the creep behaviour and tensile Strengths of plastic composited, High-Density Poly Ethylene (HDPE) certain thickness from 50% HDPE bottle and 50% HDPE 50% bran bottle, HDPE plastics from bottles and shampoo bottles. Mix bottle bran and chaff in a ratio of 50:50, 60:40 and 70:30 by weight (wt%).

          The results of the tensile test that have been compared with the 5 types of tested materials show that the material type The thickest High Density Polyethylene HDPE from the milk bottle uses more pulling force than other materials. The plastic has the maximum tensile strength of 1075.4 Newtons, which has the highest stress at 19.07 MPa and bottle-type material with 50:50 bran by weight, the plastic has the highest tensile strength of 163.47 Newtons. The maximum stress is 3.41 MPa, which requires less pulling force than other materials. The results of the creep behaviour when comparing with the 4 types of tested materials, found that all 4 types of materials that have rapid creep behaviour during the initial period have the same creep behaviour and the material with minimal creep is a bottle mixing material with husks 70:30 by weight
