需要根据食物选择打包袋吗？

Do you need to choose bags based on food?

因为食物温度一般不会太高，所以通常并不需要特别根据食物来选择打包袋。

Because the temperature of food is not too high, it is not necessary to choose the packing bag according to the food.

但是，一些油脂含量高的食物，如果需要高温加热的话，尽量不要直接用打包袋装着加热。

However, some foods with high fat content should not be heated directly in bags if they need to be heated at high temperature.

由于塑料制品中的一些成分是脂溶性的，如果食物中油脂含量高，就非常有利于它们的溶出，虽然不一定有害，但也不是什么好事。

Because some components in plastic products are fat soluble, if the oil content in food is high, it is very conducive to their dissolution. Although it is not necessarily harmful, it is not a good thing.

建议不要盛装油脂多的食物，比如毛血旺、水煮肉片这类油多的食物，就不要把汤水中的油脂都装到打包袋里了。

It is recommended not to hold greasy food, such as maoxuewang and boiled meat slices, and not to put the grease in the soup into the packing bag.
           

打包的饭菜多长时间内要进冰箱呢？

How long does the packaged food go into the refrigerator?

打包回家的饭菜，当然是要放进冰箱冷藏保存。

Packed meals, of course, should be put into the refrigerator.

不过，多长时间内放冰箱比较好呢？基本原则是能快则快。

But how long is it better to put it in the refrigerator? The basic principle is to be quick as you can.

因为打包的饭菜经过多人食用、暴露在空气中，很容易有各种细菌增殖，所以尽量马上放冰箱冷藏。

Because the packaged food after many people eat, exposed to the air, it is easy to have a variety of bacteria proliferation, so try to put the refrigerator immediately.

总之能尽快放冰箱就尽快放冰箱，不要拖泥带水，而且下次一定要再次充分加热熟透，才能放心食用。

In a word, if you can put it in the refrigerator as soon as possible, don't drag the mud and water, and next time, you must heat it thoroughly again, so that you can eat it safely.
