Environmental impacts and consumer concerns have necessitated the study of bio-based materials as alternatives to petrochemicals for packaging applications. The purpose of this review is to summarize synthetic and non-synthetic materials feasible for packaging and textile applications, routes of upscaling, (industrial) applications, evaluation of sustainability, and end-of-life options. The outlined bio-based materials include polylactic acid, polyethylene furanoate, polybutylene succinate, and non-synthetically produced polymers such as polyhydrodyalkanoate, cellulose, starch, proteins, lipids, and waxes. Further emphasis is placed on modification techniques (coating and surface modification), biocomposites, multilayers, and additives used to adjust properties especially for barriers to gas and moisture and to tune their biodegradability. Overall, this review provides a holistic view of bio-based packaging material including processing, and an evaluation of the sustainability of and options for recycling. Thus, this review contributes to increasing the knowledge of available sustainable bio-based packaging material and enhancing the transfer of scientific results into applications.

“…mentioned that NCC, which acted as a reinforcing filler for starch-based polymers, was ideal due to the presence of abundant surface hydroxyl groups on the NCC surface which are responsible for hydrogen bonding between the non-polar matrices and -OH groups of hydrophilic polymer matrices. High aspect ratio and mechanical strength have shown interest in using NCC as a load-bearing tool in engineering new and affordable biodegradable materials (Mishra et al, 2018). Ilyas et al (2018b) developed a sugar palm nanocrystalline cellulose (SPNCC) reinforced with sugar palm starch (SPS) bionanocomposites for food packaging application.…”

Nanocellulose Reinforced Thermoplastic Starch (TPS), Polylactic Acid (PLA), and Polybutylene Succinate (PBS) for Food Packaging Applications

Synthetic plastics are severely detrimental to the environment because nonbiodegradable plastics do not degrade for hundreds of years. Nowadays, these plastics are very commonly used for food packaging. To overcome this problem, food packaging materials should be substituted with "green" or environmentally friendly materials, normally in the form of natural fiber reinforced biopolymer composites. Thermoplastic starch (TPS), polylactic acid (PLA) and polybutylene succinate (PBS) were chosen for the substitution, because of their availability, biodegradability, and good food contact properties. Plasticizer (glycerol) was used to modify the starch, such as TPS under a heating condition, which improved its processability. TPS films are sensitive to moisture and their mechanical properties are generally not suitable for food packaging if used alone, while PLA and PBS have a low oxygen barrier but good mechanical properties and processability. In general, TPS, PLA, and PBS need to be modified for food packaging requirements. Natural fibers are often incorporated as reinforcements into TPS, PLA, and PBS to overcome their weaknesses. Natural fibers are normally used in the form of fibers, fillers, celluloses, and nanocelluloses, but the focus of this paper is on nanocellulose. Nanocellulose reinforced polymer composites demonstrate an improvement in mechanical, barrier, and thermal properties. The addition of compatibilizer as a coupling agent promotes a fine dispersion of nanocelluloses in polymer. Additionally, nanocellulose and TPS are also mixed with PLA and PBS because they are costly, despite having commendable properties. Starch and natural fibers are utilized as fillers because they are abundant, cheap and biodegradable.

The global concern over the environmental protection and bio‐sustainability of plastic waste materials has prompted a vibrant search for renewable and biodegradable polymers in the academia and industrial sectors. Amidst other biopolymers, poly(lactic acid) (PLA) is identified as the most promising thermoplastic aliphatic polyester. PLA is derived from agricultural products with unique physical and mechanical properties that are comparable with the conventional petroleum‐derived polymers. Yet, some of the properties are insufficient for advanced materials applications. Rigid nanoparticles are incorporated in the PLA matrix to alleviate its properties for specific high‐performance applications. Here, we report various approaches of preparing functional PLA nanocomposites with emphasis on the strengths and weaknesses of each of the methods, as well as the achieved properties enhancement for a targeted application. Designing high‐performance PLA nanocomposite involves careful selection of the most appropriate nanofillers or combinations of nanofillers, preparation technique and processing parameters. Besides multi‐walled carbon nanotubes (CNT) and montmorillonite (MMT) that are prominent as nucleating agents to achieve high thermal and mechanical properties, other nanofillers like silver nanoparticles (AgNP) play critical roles in improving antibacterial and high‐performance properties of PLA.
