AB  - In this study, blends based on a high density polyethylene (HDPE) and chitosan 
      (CS) were successfully prepared by melt processing, in a laboratory internal 
      mixer. The CS biopolymer content effect (up to maximum of 40%), and, the addition 
      of bentonite clay modified with quaternary ammonium salt (CTAB) impregnated 
      chitosan as a compatibilizing agent, on the properties of the blends was analyzed 
      by Fourier transform-infrared spectroscopy (FT-IR), wide angle X-ray diffraction 
      (WAXD), differential scanning calorimetry (DSC), thermogravimetric analyses (TG), 
      tensile strength, and scanning electron microscopy (SEM). The use of clay 
      modified with CTAB impregnated chitosan, employing a method developed here, 
      improved the compatibility of HDPE with chitosan, and therefore the thermal and 
      some of the mechanical properties were enhanced, making HDPE/chitosan blends 
      suitable candidates for food packaging. It was possible to obtain products of 
      synthetic polymer, HDPE, with natural polymer, chitosan, using a method very used 
      industrially, with acceptable and more friendly properties to the environment, 
      when compared to conventional synthetic polymers. In addition, due to the 
      possibility of impregnated chitosan with quaternary ammonium salt exhibit higher 
      antibacterial activity than neat chitosan, the HDPE/chitosan/organobentonite 
      blends may be potentially applied in food containers to favor the preservation of 
      food for a longer time in comparison to conventional materials.
