Abstract
This work reports the preparation of a ceramic hybrid film for keep-freshness with enhanced oxygen and moisture permeability, and antimicrobial properties using fluorine-coated illite (F-illite) and low-density polyethylene (LDPE) resin. Before the film was manufactured, a master batch of F-illite and LDPE was prepared through an extruder, and a large amount of LDPE resin was mixed to produce a film containing 4wt% F-illite. The amount and dispersity of the F-illite in the LDPE matrix were confirmed by TGA, wide-angle XRD and SEM analysis. As a result, the F-illite hybrid films had an oxygen transmission rate (OTR) of 13,430 mL/m2۰day), which is higher than 10,309 mL/m2۰day of the general LDPE film. Moreover, the water vapor transmission rate (WVTR) was 20.13 g/m2, which was higher than that of the general LDPE film 16.13 g/m2·day. In addition, the F-illite hybrid film showed more than 99% antibacterial activity against S. aureus.
