Antimicrobial activity
The antimicrobial activity of TiO2 coated polyethylene film was investigated against E.coli and S.aureus bacteria by
zone inhibition method. Figure 4 Explains assessment of the antibacterial activity of TiO2 coated HDPE films with
the concentration of TiO2. The results of zone inhibition method has been described from the figure 5 (a) & (b) , it
clearly shows that TiO2 coated polyethylene films shows good inhibition zone around the films. Figure 5 (a) shows
the activity against E.Coli and Fig 5 (b) shows against S.aureus. From Table 1 it illustrates the zone of inhibition
will increase with increase of TiO2 concentration and Table 2 illustrates Assessment of the antibacterial activity of
TiO2 coated HDPE films at different time intervals
