In order to keep food warm, send orders efficiently, and reduce costs, many restaurants will use low-cost, poor quality plastic products to hold food just out of the pot.

Be aware that ordinary plastic is not resistant to high temperatures! When it is used to hold hot food, or heated at high temperatures (above 65 degrees Celsius), the plastic will release toxins into the food. Eating with such a lunch box is equivalent to chronic poison, although the toxicity is weak, but long-term use, it will still cause damage to the liver and kidneys.

In addition, the damage to the environment of plastic lunch boxes is self-evident

Discarded plastic lunch boxes and plastic bags, which are incinerated or buried, do not degrade for hundreds of years and continue to pollute the land, sea and air......

Animals in nature are also affected, and if they eat white garbage, it will harm their health, and even starve to death because it cannot be digested in the digestive tract

Cutting down on takeout and bringing your own box is the first step

However, with so many types of reusable lunch boxes on the market, which one should you choose?

Look for food grade 304 stainless steel when purchasing insulated lunch box!

This is a grade of stainless steel produced according to American ASTM standard. The industry's common criteria are: the nickel Ni content in 304 stainless steel should be greater than 8%, and the chromium Cr content should be greater than 18%. However, there are many businesses under the banner of 304 stainless steel to sell unqualified products!

Poor quality stainless steel may exceed the standard of heavy metals, endangering human health.

So when you buy 304 stainless steel, you can ask the business about the test report, and don't be fooled by the business!

Lunch boxes preferably have a layered/divided structure. The advantage is that rice, vegetables, soup can be packed separately, and will not be tainted.

The layered structure is mostly used for the bucket shaped insulated lunch box, which covers a small area and is convenient to carry to and from work.

The dividing structure is mostly used for flat lunch boxes, which occupy a relatively large area and have a weak thermal insulation effect, but are very convenient when playing rice in the canteen.

Have you ever encountered any of these problems:

Insulated lunch boxes are not insulated

In summer, the unit has no refrigerator, and the risk of sour rice brought over has risen sharply

When you bring your own lunch box, the line before the microwave oven is endless, and the food is not hot

With the hot lunch box, you can solve the small thing of hot food from your seat, and no longer have to run to the microwave in person

After being plugged in, the inner lining of the lunch box will gradually heat up around it, and the temperature will be transferred from around the lunch box to the middle, slowly heating the rice through, and the whole process does not need to add additional water or add other things, which is simple and convenient.

...

In short, every hungry worker, at the meal point not only can not be happy to cook, but also to watch other people's mouths busy, it is simply hell of torture.

Glass lunch box

It is recommended to buy lunch boxes of high borosilicate glass and tempered glass, which have common characteristics: resistance to cold and heat shock.

High borosilicate glass high temperature resistance, acid and alkali resistance is very superior, the strain temperature difference is 520℃. Many beakers in chemical experiments are also of this material, not to mention microwave heating, it is no problem to heat on the open flame alcohol lamp!

Tempered glass has better anti-fall function, but it is generally thicker than high borosilicate glass, and it is also resistant to high temperature and poor temperature, and can be used for microwave oven and oven heating.

The box cover of this glass lunch box is best to choose a four-sided lock style, and the sealing is better. If the lid is a combination of plastic and silicone, it is not suitable to be heated together in the microwave oven, and the lid is easy to be heated and deformed.

Ceramic lunch box

Ceramic surface is more smooth and flat than other materials, so the general dirt can not "hang" on the wall, so as long as it is not the hot pot red oil that is difficult to clean, do not use detergent, water is clean.

But also pay attention to its safety when purchasing! It is recommended to choose ceramic tableware do not pay too much attention to the pattern, especially do not use the bowl with painted inner wall. Newly bought tableware can be soaked in vinegar for 2 to 3 hours to dissolve harmful substances in the glaze.

Plastic lunch box

Starting with the most common disposable tableware on the market, take a closer look at the plastic lunch box, and you will find a numbered logo on the lid or bottom of the box

This is the unique "ID card" of each plastic container, the different number indicates the different material, the triangle surrounded by three arrows indicates that food grade plastic is used, the "5" in the triangle and the "PP" below the triangle indicates that the product is made of polypropylene (PP) material. The material is safe, non-toxic, and most importantly, high temperature resistance is very good, stable performance, and is the only plastic material that can be put in the microwave oven.

Rice husk lunch box

We are familiar with rice, but the rice shell has been ignored, and even turned into a useless agricultural waste incineration treatment, not only produce a lot of carbon dioxide, but also pollute the natural environment

In fact, the rice husk contains a lot of fiber, has a strong antibacterial property, which is why it can protect the rice in the hot and humid rice fields from being corroded by microorganisms, insects, mold and not easy to hide bacteria.

So with the blessing of modern science and technology, these "waste" is finally turned into a treasure ~ shake the body into a natural, non-harmful substances of green tableware, is the performance of the closest to the replacement of plastic products! Can enter the microwave oven, but should not be heated for a long time, degradable, environmentally friendly and healthy.

The wooden lunch box is just looking at, you can feel a fresh Japanese wind blowing, the appearance is very beautiful, loaded with delicious food, pad a small fresh meal cloth, beautiful!

It will be very textured in the hand! Circle of friends, Weibo, Instagram upload ~

But! The disadvantages are also obvious. Wooden lunch box is not good to clean, can not be pasteurized at high temperature, can not be boiled and soaked in boiling water, can not be in the oven, microwave oven, dishwasher, disinfection cabinet, not sealed, not suitable for soup dishes
