The disposable lunch boxes made of plastic are mainly made of PP polypropylene and P S polystyrene. They are non-toxic, odorless and soft. Generally, PP is used at temperatures ranging from - 6 degrees Celsius to + 120 degrees Celsius. Therefore, they are especially suitable for filling hot meals and hot dishes. They can be heated in microwave ovens or even boiled in steam cabinets. The degree can be controlled from - 20 degrees Celsius to + 110 degrees Celsius. The lunch box made of PP can be heated to 100 degrees Celsius and put into the refrigerator for refrigeration. PS is hard and transparent, but easy to tear. PS begins to soften when the temperature reaches 75 degrees Celsius, so it is not suitable for hot food.
The plastic lunch box produced by Quanzhou Yiqiang Plastics Co., Ltd. is not only made of PP material, but also food-grade PP plastic.So what is food grade PP plastic?
1). Food grade PP will not dissolve harmful substances under normal conditions and high temperature conditions.
2). Industrial grade PP will dissolve harmful substances at normal temperature or high temperature, which will cause harm to human health. Some used in food containers will have a strong odor when exposed to heat.
Food grade PP plastic can be made into any food plastic packaging, such as food special plastic bags, food plastic boxes, food straws, etc. It is safe, non-toxic and resistant to low temperature and high temperature. PP is the only plastic that can be placed in a microwave oven for heating, and has high strength and folding resistance. It will not break when it is finished at -20 °C for 50,000 times. Food grade PP sheets are commonly used with quick-frozen foods and microwave-heated food packaging.
