PLA can meet food-contact safety standards under cold or room-temperature test conditions. However, hot food use often exceeds the parameters under which compliance testing is performed , PLA hot food. This creates a gap between: What is legally tested How the product is actually used

The key factor that limits PLA in hot food use is its glass transition temperature (Tg)—the point at which the material begins to soften and lose rigidity. For standard PLA: Tg typically ranges from 45°C to 55°C This is significantly lower than: Freshly prepared hot meals Hot soups, stews, and curries Steam-intensive rice and noodle dishes Microwave reheating temperatures Once PLA exceeds this range, deformation is no longer a possibility—it is an inevitability — PLA hot food.
