“…Packaging materials need to show sufficient flexibility and resilience to compensate for the reduction in volume to preventing irreversible deformations [170]. A big effort for reducing packaging waste has encouraged the exploration of new bio-based packaging materials, such as edible and biodegradable films from renewable resources.…”

Available online xxxxPoly(lactic acid) (PLA), so far, is the most extensively researched and utilized biodegradable aliphatic polyester in human history. Due to its merits, PLA is a leading biomaterial for numerous applications in medicine as well as in industry replacing conventional petrochemical-based polymers. The main purpose of this review is to elaborate the mechanical and physical properties that affect its stability, processability, degradation, PLA-other polymers immiscibility, aging and recyclability, and therefore its potential suitability to fulfill specific application requirements. This review also summarizes variations in these properties during PLA processing (i.e. thermal degradation and recyclability), biodegradation, packaging and sterilization, and aging (i.e. weathering and hygrothermal). In addition, we discuss up-to-date strategies for PLA properties improvements including components and plasticizer blending, nucleation agent addition, and PLA modifications and nanoformulations. Incorporating better understanding of the role of these properties with available improvement strategies is the key for successful utilization of PLA and its copolymers/composites/blends to maximize their fit with worldwide application needs.© 2016 Elsevier B.V.

“…For all these reasons, the development of a fully biodegradable starch-based material for the production of rigid-food packaging such as trays is currently a challenge not only for scientist but also for industry [7] . Nevertheless, starch also presents several drawbacks, which are preventing the employment of this material for the production of food-packaging trays.…”

Biodegradable polymers are starting to be introduced as raw materials in the food-packaging market. Nevertheless, their price is very high. Starch, a fully biodegradable and bioderived polymer is a very interesting alternative due to its very low price. However, the use of starch as the polymer matrix for the production of rigid food packaging, such as trays, is limited due to its poor mechanical properties, high hidrophilicity and high density. This work presents two strategies to overcome the poor mechanical properties of starch. First, the plasticization of starch with several amounts of glycerol to produce thermoplastic starch (TPS) and second, the production of biocomposites by reinforcing TPS with promising fibers, such as barley straw and grape waste. The mechanical properties obtained are compared with the values predicted by models used in the field of composites; law of mixtures, Kerner-Nielsen and Halpin-Tsai. To evaluate if the materials developed are suitable for the production of food-packaging trays, the TPS-based materials with better mechanical properties were compared with commercial grades of oil-based polymers, polypropylene (PP) and polyethylene-terphthalate (PET), and a biodegradable polymer, polylactic acid (PLA).

Food packaging is one of the essential subject areas in food technology that play an important role in preserving all types of foods. Due to many disadvantages like a non-biodegradable and environmental problem in food packaging industry, a newer concept of use of biodegradable materials in food packaging from botanicals created tremendous innovative ideas in food packaging from past few years. An increased interest in hygiene in everyday life as well as in food, feed, and medical issues lead to a strong interest in films and blends to prevent the growth and accumulation of harmful bacteria. A growing trend is to use synthetic and natural antimicrobial polymers, to provide non-migratory and non-depleting protection agents for application in films, coatings, and packaging. The aim of this review was to offer a complete view of the state of the art on natural biodegradable polymer packages for food application compared to synthetics. Also, heightened overall developments in botanicals, natural and synthetic biopolymers in food packaging and its applications were described by focusing future improvements. This is a timely review as there has been a recent renewed interest in research studies, both in the industry and academia, towards the development of a new generation of biopolymer-based food packaging materials with possible applications in other areas. A lot of achievements in nanotechnology compared to synthetic materials attracted food industry for its wonderful applications in packaging was highlighted.
