Which biopolymer is commonly used for single‑use bottles?

Explanation:
Polylactic acid (PLA) is the biopolymer commonly used for single‑use bottles because it can be made from renewable resources like corn sugar and processed in standard bottle manufacturing methods to produce clear, rigid, beverage-grade bottles. It combines good clarity and processability with a biobased origin, and many PLA bottles are designed to be industrially compostable, aligning with sustainability goals. Other options exist in the biopolymer family, but they are typically less common for mainstream bottle production due to factors like cost, barrier properties, or processing considerations.
