You can put hot food in plastic containers that are made of high-quality material. At SK Packaging, our round tamper evident containers are made using the best quality plastic. This makes them microwaveable and suitable for hot food up to 85°C. Heating food or storing hot food in containers made from low-quality plastic is not recommended. This is because the chemicals from low-grade plastic can contaminate the food and change its genetic composition. Hence, we suggest checking the quality of the plastic container before putting hot food inside of it.
