LDPE-Nanoclay films for food packaging with improved barrier properties

Abstract: This study focuses on the development of low-density polyethylene matrix nanocomposite films for food packaging industry and aims at improving low-density polyethylene oxygen barrier properties while maintaining other relevant characteristics, such as processability, easy post-processing, optical and mechanical properties. low-density polyethylene nanocomposites, with 1 and 2.5 wt.% nanoclay (NC) and also compatibilized with 5 wt.% polyethylene grafted with maleic anhydride (PE-g-MA), were prepared and used t… Show more

“…To obtain them, nanoparticles of various substances are introduced into the polymer matrix, and the resulting polymer composites may have, among other features, better mechanical properties, lower gas permeability, and increased microbiological resistance [ 5 ]. In some cases, introducing fillers into the polymer matrix also has economic reasons [ 6 ]. A variety of products are used to produce polymer composites, including biopolymers, such as lignin [ 1 , 7 , 8 , 9 , 10 , 11 , 12 ] and cellulose [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]; inorganic substances, e.g., titanium dioxide [ 20 , 21 , 22 , 23 ]; and hybrid materials, e.g., MgO/lignin [ 24 ] or TiO 2 /lignin [ 25 ].…”

“…The LDPE/SEBS blend is classified as immiscible and incompatible, that is, just mixing the two phases does not guarantee the achievement of the desired properties. Incompatible blends do not have mechanical performance, thermal and chemical resistance sufficient to be intended for application [6][7][8][9][10].…”
