Morphological, Structural, Thermal, Permeability, and Antimicrobial Activity of PBS and PBS/TPS Films Incorporated with Biomaster-Silver for Food Packaging Application

Abstract

The development of antimicrobial film for food packaging application had become the focus for researchers and scientists. This research aims to study the characteristics and antimicrobial activity of novel biofilms made of poly (butylene succinate) (PBS) and tapioca starch (TPS) added with 1.5% or 3% of Biomaster-silver (BM) particle. In morphological examination, the incorporation of 3% BM particle was considerably good in forming well-structured PBS film. Meanwhile, the functional groups analysis revealed the 3% BM particle was effectively interacted with PBS molecular chains. The flame retard behavior of BM metal particle also helped in enhancing the thermal stability for pure PBS and PBS/TPS films. The nucleating effect of BM particles had improved the films crystallinity. Small pore size features with high barrier property for gas permeability was obtained for BM filled PBS/TPS films. From antimicrobial analysis, the BM particles possessed antimicrobial activity against three bacteria Staphylococcus aureus, Escherichia coli, and Salmonella Typhimurium in which PBS/TPS 3% BM film exhibited strong antimicrobial activity against all tested bacteria, however, PBS/TPS 1.5% BM film exhibited strong antimicrobial activity against E. coli only. Hence, the incorporation of BM into PBS/TPS film could be a sustainable way for developing packaging films to preserve food products.

A Brief Review of Poly (Butylene Succinate) (PBS) and Its Main Copolymers: Synthesis, Blends, Composites, Biodegradability, and Applications

“…In terms of brittleness, PBS is more rigid than PBSA but slightly ductile [ 27 ]. PBS also has good thermal stability [ 28 ]. Moreover, its high flexibility guarantees its use in many application involving film production [ 21 , 29 , 30 , 31 , 32 ].…”

Sustainable Bio-Based Polymers: Towards a Circular Bioeconomy

“…The valorization of biomass from different renewable resources (i.e., agriculture, food, forestry, fishery, etc.) by green processes to produce multifunctional polymers with potential industrial applications is a smart strategy to substitute non-biodegradable petroleum-based plastics [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. This allows a change of paradigm from a linear economy (“take, make, and dispose”) to a circular bioeconomy where typical plant and animal residues littered as wastes have a second chance and can be re-integrated into the productive cycle, thus reducing their environmental impact.…”

“…This allows a change of paradigm from a linear economy (“take, make, and dispose”) to a circular bioeconomy where typical plant and animal residues littered as wastes have a second chance and can be re-integrated into the productive cycle, thus reducing their environmental impact. In this context, the works published in this Special Issue have addressed such a topic from different perspectives, including bio-based alternatives to petroleum-based polymers [ 3 , 8 , 9 , 12 ], bioplastics for packaging [ 2 , 4 , 10 ] and other industrial uses [ 6 , 7 ], and sustainable food waste management and biorefinery [ 1 , 5 , 11 ].…”

“…In summary, ten papers about the fabrication, characterization, and potential uses of bio-based polymers and composites have been published in this Special Issue [ 1 , 2 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. It also contains two reviews about sustainable substitutes of phenol-formaldehyde resins [ 3 ] and synthetic and non-synthetic materials for packaging and textile uses [ 4 ].…”

“…Aziman et al reported an investigation about the incorporation of Biomaster-silver (BS) particles into poly(butylene succinate) (PBS) and PBS/tapioca starch (TPS) polymer matrices as food packaging films [ 2 ]. BS particles were well distributed in both polymer matrices and interacted preferentially with the PBS fraction.…”
