Mechanical Properties and Thermal Behavior of TPS/PBS Blends with Maleated PBS as a Compatibilizer

Abstract

Thermoplastic starch/poly (butylene succinate),an entirely biodegradable polymer blend was prepared using a two-step extrusion process. The mechanical properties and thermal behavior of TPS/PBS blends were investigated. The results demonstrated that the strength and elongation at break of TPS/PBS blends were greatly improved with the addition of rPBS in PBS blends due to its contribution in the improvement of interfacial compatibilizing and miscibility.

Efficacy of Biopolymer/Starch Based Antimicrobial Packaging for Chicken Breast Fillets

“…The addition of TPS on both untreated and treated films resulted in lower log values than the control from day 3 storage onwards. This further indicates that the addition of TPS to PBS made it partially compatible polymer blends [11]. Among all the samples, the PP container (control) exceeded the acceptability limit on the fifth day of storage; however, other treatments for chicken samples were still acceptable up to seven days.…”

“…Moreover, pre-plasticized starch could promote larger surface reaction and improve homogenization during compounding thermoplastic starch/PBS thin films [10]. The addition of maleated PBS as compatibilizer to thermoplastic starch/PBS blends could provide the combined properties of great water resistance, enhanced strength, and good biodegradability, and is anticipated to serve as promising packing material [11]. However, the application of PBS is restricted due to several limitations, such as microbiological corrosion and low mechanical strength [12].…”
