“…The main advantage of this technique is its lower costs due to elimination of complex processes such as polymerization reactions and purification of final products. The technique also applies avail-able components where it is performed on similar extruders in industry [60]. On the other hand, injection molding technology to produce pellet film of fiber-reinforced thermoplastic composite is illustrated in Fig.7 adopted from Tanaka (2013).…”

Petroleum-based synthetic polymers are mostly used for packaging materials for their advantageous features such as flexibility, lightness and transparency. However, the waste caused by the increasing usage has led to serious environmental impacts. There are many packaging products claimed as ‘green’ material in the market but, they are not fully from natural renewable resources. Most biocomposites materials comprised only either the matrix or fiber/filler from natural renewable resources, but still blended with another synthetic compound. Thus, green biocomposites which composed of fully biodegradable natural fibers and biopolymer matrix would be a great alternative. It can be naturally degraded and completely return to the environment safely after usage. The main shortcomings of biopolymer are their inadequate of mechanical and barrier properties in product application. Yet, the embedding reinforcing fibers or fillers would help in improving the final properties of the composites. The intention of this review is to present the latest development of green biocomposites research and its application for food packaging. It is also proposed to provide critical information that covers around properties of green biocomposites, types of available biopolymers and natural fibers, including their manufacturing techniques. Furthermore, the economic circumstances and forthcoming trend of these materials in food packaging industry would also be reviewed

“…Depending on the woody material, different properties of the composite material can be obtained. However, from a commercial standpoint, usually materials that are conveniently available from the supply side are utilized rather than based on the characteristics of the fibers [ 20 ]. In Southeast Asia, hemp, ramie, kenaf and so on are mostly used as fillers as they are abundant there.…”

“…However, in the US, species mostly utilized as fillers are the softwoods such as white pine, spruce, hemlock; and hardwood such as aspen. In general, the size of wood flour for manufacturing WPCs ranges from 1 mm–100 µm (18 mesh–140 mesh) [ 20 ]. However, the particle size of wood flour most preferable for composite products is in the range of 180–425 µm (40–80 mesh size) [ 21 ].…”

Properties of Wood–Plastic Composites Manufactured from Two Different Wood Feedstocks: Wood Flour and Wood Pellets

2021

Driven by the motive of minimizing the transportation costs of raw materials to manufacture wood–plastic composites (WPCs), Part I and the current Part II of this paper series explore the utilization of an alternative wood feedstock, i.e., pellets. Part I of this study reported on the characteristics of wood flour and wood pellets manufactured from secondary processing mill residues. Part II reports on the physical and mechanical properties of polypropylene (PP)-based WPCs made using the two different wood feedstocks, i.e., wood flour and wood pellets. WPCs were made from 40-mesh wood flour and wood pellets from four different wood species (white cedar, white pine, spruce-fir and red maple) in the presence and absence of the coupling agent maleic anhydride polypropylene (MAPP). With MAPP, the weight percentage of wood filler was 20%, PP 78%, MAPP 2% and without MAPP, formulation by weight percentage of wood filler was 20% and PP 80%. Fluorescent images showed wood particles’ distribution in the PP polymer matrix was similar for both wood flour and ground wood pellets. Dispersion of particles was higher with ground wood pellets in the PP matrix. On average, the density of composite products from wood pellets was higher, tensile strength, tensile modulus and impact strength were lower than the composites made from wood flour. Flexural properties of the control composites made with pellets were higher and with MAPP were lower than the composites made from wood flour. However, the overall mechanical property differences were low (0.5–10%) depending on the particular WPC formulations. Statistical analysis also showed there was no significant differences in the material property values of the composites made from wood flour and wood pellets. In some situations, WPC properties were better using wood pellets rather than using wood flour. We expect if the material properties of WPCs from wood flour versus wood pellets are similar and with a greater reduction in transportation costs for wood pellet feedstocks, this would be beneficial to WPC manufacturers and consumers.
