The problems derived from this convenience cannot be ignored. An environmental organization survey found that an average of 3.27 disposable plastic lunch boxes/cups are consumed for each order, which means that after 256 million orders of diners are full each day, it means that at least 830 million plastic lunch boxes and disposable chopsticks will be produced. , Plastic bags and other take-out garbage is shocking!

From the initial foaming type to the degradable type, the widespread use of disposable foaming lunch boxes has been increasing. Office workers and students are the main people who use disposable lunch boxes. The data shows that 260 million tons of plastic are used globally every year, 170 million of which are for one-time use, and currently only 14% of plastic packaging is recycled, which means that most of the waste plastic is discarded. It is understood that most people know that there are many controversies about disposable lunch boxes from the perspective of hygiene and environmental protection, but they are only used for convenience. Not all disposable lunch boxes on the market today meet national standards. Long-term use of unqualified lunch boxes will have adverse effects on the body, so perhaps bringing your own lunch boxes should be the first choice.

Of course, this is an economy spawned by the Internet. It is not realistic to reduce the number of takeaways. After all, everyone has become accustomed to this lifestyle. Starting from the source and downstream ends, replacing the meal box materials, and strengthening recycling, may improve the efficiency of environmental protection and balance the problems caused by economic development. Sheng Min, Secretary-General of the Recycling Plastics Branch of China Renewable Resources Recycling Association, said: "At present, my country still does not have a corresponding subsidy mechanism for the recycling of waste plastics and other renewable resources." At present, my country has two models that can be used for reference: one is the European model. The government adopts compulsory policies to subsidize the recycling and processing of renewable resources. The other is the Japanese model, which cultivates the quality of the people and sorts waste from the source.

With the increasing awareness of environmental protection, many people have begun to reuse disposable fast food boxes. For this reason, at the end of the article, I will give everyone a little knowledge about plastics: What kind of logos are on the bottom of the plastic box, what do they mean, and which logo can be microwave heated?

In general, there are 7 types of logos on the bottom of the plastic box. The plastic boxes with these logos are made of different materials, so not all lunch boxes can be heated in a microwave oven. You need to carefully screen them before use. Next, let us analyze some of these seven logos separately!

PET (polyethylene terephthalate)

Introduction: Most of the bottles with the "PET" logo on the bottom are beverage bottles. Needless to say, everyone knows that this kind of plastic products are "disposable". Pour hot water into the mineral water bottle and even burn the bottle. It has a plastic smell, and long-term use can cause harm to humans.

Heat resistance: easy to deform at 70℃

Whether it is suitable for microwave: not suitable

HDPE (High Density Polyethylene)

Introduction: Plastic products with plastic components such as milk bottles, shampoos, detergents, etc., are recognized in the industry that they will not release harmful substances and are relatively safe, so supermarkets will also use this kind of plastic bags for food. However, this kind of container is generally not easy to clean, and it is easy to breed bacteria. It is not recommended to recycle.

Heat resistance: 110℃ high temperature

Whether it is suitable for microwave: not suitable

PVC (Polyvinyl Chloride)

Introduction: Used in plastic food packaging, children's toys, oil bottles, vinegar bottles, soy sauce bottles, etc. Many plastic boxes made of PVC material say "Microwaveable", but heating of this material will release harmful substances and interfere with human hormone development. , Many countries’ environmental protection agencies have already announced the ban.

Heat resistance: 80℃

Whether it is suitable for microwave: not suitable
