It is best to use glass, ceramic or microwave-safe plastic containers for heating food. If you really need to cover the container with PVC Cling Film For Food, you should pay special attention to the following points:
01 Cling film that is not marked as suitable for microwave ovens must not be used in microwave ovens.
Pay attention to the maximum heat-resistant temperature marked on them, try to choose plastic wrap with higher heat resistance, and the use time should not be too long.
02Keep a certain distance from food.
In fact, whether it is used for heating or not, it is recommended to use plastic wrap with deep containers, that is, keep them at least two centimeters away from the food, so that the plastic wrap only contacts the container and not the food itself. Especially oily foods can easily cause the plastic wrap to break and stick to the food after heating.
03 Poke a few small holes with a toothpick.
Before heating, you can use toothpicks to poke a few small holes in the plastic wrap to facilitate the evaporation of water vapor. Otherwise, it is easy to cause the plastic wrap to burst due to gas expansion, and even cause danger.
Please also pay attention to the following points when using
Do not cover freshly cooked hot dishes with plastic wrap. Because covering the vegetables when they are hot will not only fail to preserve the vitamin C in the vegetables, but will increase its loss. Pyrex, porcelain plates, etc. can be chosen to cover food instead.
No matter what kind of plastic wrap is made, it is not suitable to come into contact with alcoholic foods, and it is not suitable to wrap oily cooked food, meat and other foods for a long time.
Wrap fresh fruits and vegetables in plastic wrap. PVC Cling Film For Food can provide longer preservation time because of its better moisturizing properties, but it is recommended not to exceed 12 hours. The function of plastic wrap is to keep food fresh for a short period of time, not for long-term storage.
Fruits and vegetables wrapped in plastic wrap purchased from supermarkets must be thoroughly washed before consumption.
For fruits and vegetables kept fresh by refrigeration or freezing, it is the safest principle to use clean paper towels to isolate them first, and then use plastic wrap to keep them fresh.
Not all fruits and vegetables can be used with PVC Cling Film For Food. Studies and experiments have shown that using plastic wrap to preserve fruits and vegetables with high moisture content such as apples, pears, rapeseed, leeks, and lettuce can not only keep them fresh for a long time, but also increase the content of vitamin C and other nutrients. When using them to keep radish, cucumber, beans, etc. fresh, the nutritional loss will be great.
