Effect of storage temperature on the antioxidant properties of active bilayer polyethylene/soy protein isolate (PE/SPI) film

Polyethylene (PE) is considered to be one of the most widely used plastic in the world due to its vast array of applications depending on the particular type. It is well known that petroleum-based plastic is a good material for food packaging for its good mechanical properties. Meanwhile, biopolymer...
