instruction for use
1, when heating oily food, the plastic wrap should be kept in isolation from the food, and the two should not be in direct contact. Because when the food is heated, the food oil may reach a very high temperature, so that the plastic wrap is damaged and sticks to the food.
2. When heating food, cover the container with plastic wrap, and then stick a few small holes in the plastic wrap with needles such as toothpicks to facilitate the evaporation of water and prevent the plastic wrap from bursting due to gas expansion.
3. The maximum heat-resistant temperature marked by different brands of plastic wrap is different, and some of them are about 10℃. When the temperature in the microwave oven is high, it will generally reach about 1 10℃. When it needs to be heated for a long time, you can pay attention to choosing plastic wrap with higher heat resistance.
