Through hindering the penetration of gas
molecules and increasing their average path length, the high aspect
ratio of the added particles might develop a permeation barrier in the LDPE, which may account for the decreased transmission rate of
CO2 and O2 of LDPE packaging after the adding of nano-CaCO3
(Hosseinkhanli et al., 2013). The rapid formation of gas environment with lower O2 concentration and higher CO2 concentration is
beneficial for the storage of fresh-cut yam
