Details to be noted when using food fast-food boxes

Nowadays, when dining in a restaurant, food takeout boxes are usually provided for packing up any uneaten food to take away. However, it should be noted that these food takeout boxes are, after all, plastic boxes, and there are certain details to consider when using them:

1. Microwave heating: There are various types of packaging boxes made of different materials. Plastic packaging boxes made of PP material are marked with a triangular arrow and the number 5 inside, indicating that they can be used for microwave heating. Other plastic packaging boxes cannot be heated in a microwave oven. In addition, foam and paper packaging boxes cannot be heated in a microwave oven. When using glass packaging boxes for heating, the heating time should not be too long.

When storing liquid in a sealed container at high temperatures, due to the effect of vapor pressure, the sealing performance may slightly deteriorate. Please store the liquid at an appropriate temperature to prevent leakage.

3. Temperature resistance: Cup body -20~120°, Cup lid -20~80°.

4. When storing high-sugar, greasy liquid beverages, the sink is not suitable for use in a microwave oven.

5. Do not touch or approach the fire source to avoid melting and deformation. Do not apply strong impact to the packaging box, nor use a brush or powder for cleaning.

Can disposable fast food containers be used in the microwave

Nowadays, when dining at restaurants, people often practice the "clean plate" rule, and sometimes they will pack up any uneaten food to take away. This has led to a high utilization rate of disposable fast food containers and food containers. Generally, disposable food containers made of ordinary materials cannot be heated in the microwave because they have a low melting point and will melt when heated. The heated food may fuse with the container, resulting in an unpleasant taste! Secondary foam plastic will melt and undergo chemical reactions when exposed to heated oil.

Microwave lunch boxes are generally made of PP and PS plastics. PP, which stands for polypropylene, has good mechanical and thermal properties and is used in various laminated boards and packaging materials. PS, commonly known as hard plastic, is hard and brittle, and when knocked, it produces a metallic "ding-dong" sound, also known as "resonant plastic". It is non-toxic and odorless, and this material can be used for packaging. It is also environmentally friendly to use. Lunch boxes made of PP material are relatively soft, while those with PS added are slightly harder. There is no other significant difference in other aspects.

These two materials will not release toxic substances when heated in a microwave oven. However, it is important to note that most lunch boxes will be labeled indicating whether they are suitable for use in a microwave oven. Some lunch boxes are not made of PP and cannot be heated in a microwave oven. When serving hot meals, do not use the lid. If the plastic lunch box does not indicate the material or contain words such as "suitable for microwave oven", it cannot be heated in a microwave oven. Such lunch boxes may be of inferior quality and should not be placed in a microwave oven.
