Disposable fast food boxes have shifted from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated because they were not resistant to high temperatures and the production process caused damage to the environment. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, and degradable lunch boxes are being replaced. etc. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, easy production and relatively low cost, so it has become the mainstream material for manufacturing disposable fast food boxes.
So what should we pay attention to when using disposable lunch boxes? Let me tell you about it below:
1. Pay attention to the usage temperatures of lunch boxes made of different materials. Lunch boxes made of PP have a higher operating temperature and can be used to hold hot meals and dishes. Lunch boxes made of PS are hard and easy to break. They begin to soften when the operating temperature reaches 75°C. The food should be cooled to room temperature before being put into the PS lunch box. Try not to heat the food in the microwave oven with the box as its low-temperature properties Very good for holding refrigerated food.
2. Different food ingredients have requirements for meal boxes. Foods with high fat and sugar content are not suitable for packaging in lunch boxes because the boiling point of oil easily exceeds the heat resistance limit of plastic. Oil, sugar in food, and plasticizers and other chemical substances in lunch boxes are all organic matter. According to similar conditions, Due to the principle of dissolution, chemical reactions may occur with the lunch boxes, posing potential risks to public health and food safety.
