PP (polypropylene) and PLA (polylactic acid) containers serve different roles in foodservice based on their material properties and sustainability profiles.
PP containers are highly durable, microwave-safe, and resistant to heat, making them ideal for both hot and cold food applications. They're lightweight, reusable to some extent, and widely recyclable as plastic #5 in many areas. However, they are petroleum-based and not biodegradable.
PLA containers, by contrast, are made from renewable resources like corn starch and are compostable in industrial settings. While they offer a better environmental profile, they are less heat-resistant than PP, making them better suited for cold food or light-duty applications.
Ultimately, PP is the better option for high-performance needs, while PLA supports operators with eco-forward goals in composting-friendly regions.
