Which biopolymer is used for packaging films?

• A. Corn starch polymer
• B. PLA
• C. Biobatch
• D. Glycolide

Answer: (C)

Packaging films need a biopolymer that can be melted and drawn into thin, clear, flexible films while also being environmentally friendly. Biobatch fits this requirement because it is a starch-based biopolymer designed for film production, giving good film-forming ability, flexibility, and compostable behavior. These properties make it practical for making packaging films using standard film-processing methods. Corn starch polymer can form films but tends to be brittle unless you add plasticizers or blend with other materials. PLA is widely used for biodegradable films and offers good clarity, but it can be brittle and has processing and aging considerations. Glycolide, or polyglycolide, provides strong barrier properties but is expensive and not as well suited to general packaging films. So Biobatch stands out as a purpose-built option for film packaging among the choices.
