In the present study, the antimicrobial activity of the different active
films spiked with PVPP-WS natural extract against selected spoilage microorganisms
was evaluated and compared with that of control films.
The LDPE and EVA films (controls and active films spikedwith 3% natural
extract: LDPEC, LDPE3%, EVAC and EVA3%) were tested against different
microorganisms (see Section 2.6). The LDPE active films did not display
antimicrobial activity (data not shown), and the EVA active film
(EVA3%) was the only film with antimicrobial activity (see Table 3).
