Incorporation of other antimicrobial agents into polyolefins

 Antimicrobial activity
Antimicrobial agent/polymer fabrication method Minimum concentration contact time (method) bacteria reduction Remarks Ref.
Nisin/PE Melt blending & film casting

  • NR

  • 24 h (inhibition zone)

  • Show good inhibition zone against

  • B. thermosphacta

Adding polyethylene oxide or EDTA significantly improves activity Cutter et al. (2001)
BTMP/PP Synthesize Cl-BTMP and solvent casting

  • > 0.1 wt%

  • > 15 min (AATCC 100)

  • 100% (E. coli and S. aureus)

 Ability to recharge and durable Chen and Sun (2005a, 2005b)
Benzoic anhydride/LDPE Solvent casting

  • 2%

  • Inhibition and rate of growth

  • fully inhibited against

  • (A. toxicarius, Pencillium)

 Released benzoic acid is active compound Weng and Hotchkiss, (1993)
