“…However, all the composite films with SP showed relatively lower elongation at break. This might be related to the slight increase in hardness and brittleness that occurred when inorganic SP was introduced into the flexible PP structure and the poor interfacial interaction and agglomeration of SP in the PP matrix, which was more noticeable at high concentrations of SP. The FTIR and SEM results support this reasonable explanation.…”

To prolong the shelf life of bread, polypropylene/sodium propionate (PP/SP) composite films were prepared via a melt‐extrusion process. To investigate the feasibility of using PP/SP composite films as a bread packaging material, their chemical structure, morphology, mechanical properties, barrier properties against water, surface properties, and antimicrobial properties were investigated. A storage test for bread was also conducted. The mechanical and thermal stability of the PP/SP composite films enhanced with increasing SP content. Compared with pure PP, the PP/SP composites had increased hydrophilicity that increased with increasing SP content. These composite films showed enhanced antimicrobial activity against both Gram‐negative and Gram‐positive microorganisms. This was due to the interaction of SP and water originating from the bread, which modifies the pH of the bread and causes destruction of the cellular structures of fungi and also reduces the growth rate of bacteria. The enhanced thermal, mechanical, antifungal, and antimicrobial properties achieved by the addition of SP can be beneficial for maintaining the freshness of bread and prolonging its shelf life.

“…They largely contain organic lignocellulosic fibers (mostly cellulose‐rich fibers, 70%–100%), little amount of inorganic fillers such as calcium carbonate, clay, titanium oxide, etc. (0%–30%) and printing inks . Cellulose is a classical example of most copious biogenic materials that offers a great perspective for the development of high‐end application products with remarkable properties of being ecofriendly, renewable, biodegradable, and biocompatible .…”

“…To alleviate these concerns, studies are under way to utilize abundantly available cellulosic materials as an operative substitute of these inorganic fillers. In this regard, use of waste paper as fillers to prepare polymer composites will be inexpensive and can play a potential role in reducing environmental load due to their characteristic biodegradability and hence can play an impending role in resolving various environmental problems. Waste paper‐filled polymer composites will not only contribute to sustainability but will also offer numerous value added benefits like enhanced specific stiffness, less abrasiveness, and flexibility during processing coupled with low cost per unit volume basis .…”

The present work aims to study the perspectives of an efficient utilization of waste products as fillers for the thermoplastic polymer. Maleic anhydride grafted linear low‐density polyethylene (LLDPE‐g‐MA), without any compatibilizers, has been used as polymer matrix to prepare composites with different contents (0–50 phr) of waste paper powder (WPP). Mechanical properties assessment has shown up to 88% improvement in tensile strength and a huge increment of 409% in Young's modulus for the composites prepared at 30 phr WPP. The reinforcement effect of WPP in the polymer matrix was also assessed by Guth‐Gold and modified Guth‐Gold equations. Microstructural analysis of the fractured surfaces revealed good interfacial adhesion with fewer voids and fiber pull out up to 30 phr WPP loading. Interfacial interaction between maleic anhydride group of LLDPE‐g‐MA and OH groups present dominantly in the cellulosic component of WPP was established through Fourier transform infrared spectroscopy. The thermal properties of prepared composites were analyzed by differential scanning calorimetry. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45167.

Natural fibers are seeing increased use in composite applications due to their reduced cost, low density, and environmental benefits (more sustainable and lower carbon footprint). Although many natural fiber systems have been examined over the last decade, there have been relatively few studies which have compared a variety of fiber types and processing methods directly in the same experimental set. In this study, natural fiber composites made from low density polyethylene (LDPE) and a variety of Canadian based fiber feedstocks were examined including hemp bast, flax bast, chemically pulped wood, wood chips, wheat straw, and mechanically pulped triticale. The effect of fiber type, fiber fraction and maleic anhydride polyethylene (MAPE) coupling agent on the mechanical properties and long-term moisture absorption behavior was quantified. In general, addition of natural fiber to LDPE results in an increase in modulus (stiffness) with a corresponding loss of material elongation and impact toughness. Of the fiber types tested, composites made from chemically pulped wood had the best mechanical properties and the least moisture absorption. However, the use of MAPE coupling agent was found to significantly increase the mechanical performance and reduce moisture absorption for all other natural fiber types.
