1. The applicable temperature of the product and the microwave oven. In the national standard of QB/T 4049-2010, the test method of applicable temperature requires that the water at the nominal temperature (below zero is ice) is poured into the container, and there is no deformation after 10 minutes , No cracks, you can pass the experiment. If the plastic cup you buy needs to be heated, it depends on your general demand and whether it meets your needs. Generally speaking, the temperature of boiling water after being poured into a plastic cup is 96 degrees. So I am also very curious about how some cups are said to be resistant to 120 degrees (hasn't all the water vaporized?). If the nominal temperature of the cup is 100 degrees, it should be possible to heat it in a microwave oven with water. But if you add a plate of braised pork with oily broth and you say you want it to be heated in a microwave oven, then I can only do it. The oil temperature can reach more than 200C, did you say that the plastic cup is affected?

2. Safety mainly depends on the material. Generally speaking, domestic PC and PP are common choices. In the past 10 years, Tritan, a new material in major developed countries, has quickly replaced PC as the main material of plastic cups (such as this lock cup) because it does not contain bisphenol hormones. . Due to PC safety concerns, in Europe, America, Japan and South Korea, it is already difficult for you to buy PC cups. There are also many Tritan lunch boxes abroad, so as long as it does not exceed the plastic temperature, the safety of microwave heating is also acceptable.

3. Falling. The main advantage of plastic cups to glass cups is that they are resistant to falling, but the performance of falling resistant is also different in different plastic cups. In the national standard of QB/T 4049-2010, the drop performance is defined as three categories: A, B, and C. Type C is not required (so it should be broken at the first touch), Type B is a 50-centimeter wooden floor falling through, and Type A is a 1.5-meter drop from a concrete floor full of water. In the current market, there are not many that fall into category A. Of course it also depends on your personal needs.

4. Appearance permeability and odor---it needs to be focused. The above items, as long as they are products of regular manufacturers, can be clearly seen by looking at the label. However, appearance permeability and smell are actually a key to the conscience of manufacturers. Simply put, if the recycled material (recycled material) is added too much, the black spots will inevitably increase and the permeability will decrease. The smell of plastic cups generally comes from soft rubber (sealing strip) materials. The quality of soft rubber materials is still somewhat related to the smell. If you see a lot of tea bags in the water cup packaging, then you know what the manufacturer has to cover up.
