1. Standard high-transparency PLA cold drink cups (the style shown in the picture)

Safe operating temperature ≤50°C; it will soften and deform at 55–60°C. Only suitable for iced and room-temperature beverages, not for hot water or hot milk tea.

2. Heat-resistant modified PLA cups

Maximum heat resistance reaches 85–90°C, yet with poor transparency. They cannot be made into crystal-clear display cups and are rarely used for milk tea and cold drinks.
