“…Typically, the addition of reinforcing particles leads to a decrease in this property of plastic films. 40,43 This behavior is exhibited in the transverse direction of the films. However, this effect is not evident in the machine direction.…”

“…For instance, Cloisite 20A has been successfully used to increase the tensile strength of plastic films due to their organomodified nature and good compatibility with various polymers. 39,40 The drop in tensile strength of PBAT-MMT-2 and PBAT-HNT-2 composites may be attributed to the presence of agglomerates that induce cracks in the films. 41 However, at lower concentrations, there is a strong interaction between the polymer and clay particles, resulting in effective stress transfer from the PBAT matrix to MMT and HNT.…”

Biodegradable packaging plastics combining good mechanical properties and low gas permeability is required to avoid environmental and food safety concerns. This study explores the impact of montmorillonite (MMT) and halloysite nanotubes (HNT), on the mechanical, optical, and oxygen permeability of blown film poly (butylene adipate‐co‐terephthalate) (PBAT) composites. The morphology of the films was evaluated by x‐ray diffraction (XRD), differential scanning calorimetry and scanning electron microscopy. Good distribution/dispersion of clays is found in the PBAT‐MMT films. Besides, there is an increase in the crystallinity of PBAT due to the nucleating effect of HNT. Improvement in the tensile strength and elongation at break in the machine direction is obtained up to a clay content of 1.5 vol%. The incorporation of 1.5 vol% of MMT and 1 vol% of HNT leads to a reduction in the oxygen permeability of the PBAT film by 29% and 38% respectively. Furthermore, the films remain transparent regardless of clay content. Finally, the feasibility of the films for food storage is tested in grapes, obtaining extended shelf life. The favorable mechanical, barrier and optical properties of the biodegradable films, along with the scalable production process, make them attractive for application in the storage and preservation of food products.

Nanocomposite films and coatings using inorganic nanobuilding blocks (NBB): current applications and future opportunities in the food packaging sector

The aim of this review is to provide an in-depth overview on the use of inorganic nano-sized entities for the generation of nanocomposite materials in the form of films and coatings for food packaging applications.According to recent trends toward "green" strategies, special focus has been dedicated to the development of nanocomposite coatings obtained using biopolymers as the main polymer matrix. After a first introductive part, the discussion has been addressed to the use of inorganic fillers, metals and metal-oxides, zeolites, and graphene. For each class of filler, a first 'in-depth' description of the most relevant physicochemical properties for the food packaging sector has been followed by case-by-case references to recent developments and envisaged implementations. The technical aspects that may be crucial in the design and end use of (bio)nanocomposite coatings have been covered in the last part of this work, which also includes an updated list of current applications on nano-sized inorganic fillers in the food packaging field.

“…The addition of a block or graft copolymer reduces the interfacial tension between the two phases, increases the surface area of the dispersed phase, promotes adhesion between the phase components, and stabilizes the dispersed phase morphology. [3][4][5][6][7][8][9][10] The polyolefins and poly(vinyl chloride) (PVC) are two important classes of commercial polymers. Polypropylene (PP) has advantages such as excellent mechanical properties and chemical erosion resistance, and is widely used in various fields.…”

Graft copolymers were usually introduced to improve the compatibility and mechanical properties of polymer blends. In this paper, the effect of cationic vinyl monomer grafted polypropylene (FPP) with different grafting yields (GY) on mechanical properties of polypropylene (PP)/poly(vinyl chloride) (PVC) blends had been investigated. The results indicated that FPP could enhance compatibility of PP/PVC blend remarkably. The tensile strength and the impact strength of PP/PVC blends with a concentration of FPP (GY=16.78%) at 4 phr increased up to18.10% and 74.67%, respectively. The viscosity of PP/PVC/FPP blends had been also investigated, and the results showed PP/PVC/FPP (80/20/4) blend was higher than that of other PP/PVC/FPP when FPP (GY=16.78%) was added. The SEM micrographs suggested that the compatibility of the PP/PVC blend was optimum when FPP (GY=16.78%) was added.
