    Can compostable sauce cups withstand heat, or are they suitable for cold applications only?

    Update:15 Nov 2023
    The ability of compostable sauce cups to withstand heat can vary based on the specific material used in their construction. Compostable cups are typically made from a variety of materials, such as polylactic acid (PLA), sugarcane, or other plant-based fibers. Here's a general overview of their heat resistance:
    PLA Cups: PLA is a common material used in compostable cups. It is derived from cornstarch and is known for its transparency and heat resistance. PLA cups can often withstand temperatures of up to 110 to 120 degrees Fahrenheit (43 to 49 degrees Celsius). While this makes them suitable for hot beverages, they may not be suitable for extremely hot liquids.
    Sugarcane-Based Cups: Cups made from sugarcane fibers are generally heat-resistant and can withstand hot temperatures. They are often used for both hot and cold applications and are a popular choice for compostable cups.
    Other Plant-Based Fibers: Cups made from other plant-based fibers may have varying degrees of heat resistance. 
    Using compostable cups beyond their recommended temperature limits can compromise their structural integrity and performance.
    If you intend to use compostable sauce cups for hot applications such as holding hot sauces or gravies, it's essential to choose cups that are explicitly labeled as suitable for hot foods.
