      Hardness measurements were taken with the Tukon Hardness test apparatus. Testing of hardness is done by effectively measuring a material’s resistance to indentation. Originally, the Rockwell Hardness Tester was to be used, but the smallest load choice was 15 kg ( a load far too great for the relatively soft polyethylene for this particular test.
