Because essential oil can evaporate easily at ambient temperature so ethylene vinyl acetate (EVA) was mixed in
LDPE to reduce evaporation rate of these EOs as shown in the study of Suppakul et. al. [13] Whereas Mistry Y.[14]
studied of how to reduce loss of active antimicrobial agent during the manufacturing of LDPE film because
solubility parameter of EVA is between LDPE and EOs as shown in table 2. EVA could partially adhere the EOs in
the polymer matrix.
