Properties of Films Prepared as Packaging Plastics from Blends of Synthetic Polymer and Biopolymer

Natural biopolymers were studied for their possible role as biodegradable fillers forlow-density polyethylene (LDPE) films. LDPE/biopolymer blends and films were prepared andcharacterized by the melt flow index (MFI) and tensile test. The addition of biopolymer to LDPEreduced the MFI values, the ten...

Zusammenfassung:	Natural biopolymers were studied for their possible role as biodegradable fillers forlow-density polyethylene (LDPE) films. LDPE/biopolymer blends and films were prepared andcharacterized by the melt flow index (MFI) and tensile test. The addition of biopolymer to LDPEreduced the MFI values, the tensile strength and modulus, whereas the elongation at break increased.Interfacial interaction was better for LDPE/biopolymer blends containing soybean oil. Blendsprepared with oil showed the same behaviour as LDPE/biopolymer blends, indicating thatbiopolymer was the main factor that influenced the properties of blend.
