Is the disposable lunch box poisonous? Is it harmful to your health?
Disposable lunch boxes are of course poisonous …
1 transparent disposable plastic packaging box
Whether it is transparent or opaque, as long as it is a plastic packaging box, there are plasticizers mixed in it. Adding plasticizer can make plastic packaging boxes more flexible and easier to process, but it is harmful to human body. Plasticizers in plastic packaging boxes can cause endocrine disorders. Long-term consumption of food in plastic packaging boxes will cause liver and kidney diseases and affect normal development. Of course, these terrible results have not yet appeared in humans, and they are all conclusions drawn from experiments on animals. (No microwave heating)
2, white disposable plastic packaging box
This kind of lunch box is usually filled with rice. Of course, the nature of this kind of lunch box is the same as that of transparent lunch box, and both of them are mixed with plasticizer, which makes the lunch box easy to process and enhances its flexibility. Long-term consumption of this kind of food in the box will also affect the normal development of the liver and kidneys. (No microwave heating)
3. Disposable plastic packaging box with slightly better quality
This kind of packaging box is not better in appearance than those common ordinary plastic packaging boxes, but all plastic packaging boxes will be doped with plasticizer, the same purpose is to make plastic boxes easy to process and enhance flexibility. But eating more food in this box will affect the normal development of liver and kidney. (No microwave heating)
Two disadvantages of disposable lunch box worth buying
At present, most disposable snack boxes on the market are made of polystyrene raw materials extracted from petroleum and foaming agents by heating and foaming. Polystyrene is a widely used polymer material, which has the characteristics of low toxicity, high melting point, strong plasticity and simple manufacture, and has become the first choice for making disposable fast food boxes. However, due to the very long degradation cycle of polystyrene lunch boxes, its degradation cycle is as long as 200 years in ordinary environment. In other words, keep your polymer morphology unchanged for a long time.
So what should we do with those discarded lunch boxes? Burn it? No When they burn, they will produce 10 kinds of toxic gases, which will directly cause air pollution. Buried? Neither can i. In order to shape the material, various additives must be added in the production process. With the passage of time, some toxic additives will be released gradually, causing damage to soil and water resources. What about recycling?
Unfortunately, their renewable value is extremely low, not to mention how huge it is to recycle so many large and small lunch boxes every day! Moreover, as a foaming agent, freon is recognized by the scientific community as the "culprit" that causes irreversible damage to the ozone layer in the earth's atmosphere.
It can be seen that the difficult degradation of disposable plastic lunch boxes is a major culprit in causing "white pollution". Moreover, as a foaming agent, freon is recognized by the scientific community as the "culprit" that causes irreversible damage to the ozone layer in the earth's atmosphere.
Disposable plastic lunch boxes will cause great damage to the environment, so are they absolutely harmless to the human body? Facts tell us that the answer is not the case. A new research shows that polystyrene, the raw material for making disposable plastic lunch boxes, is a carcinogenic environmental hormone. Experiments have proved that this kind of tableware will cause dioxin at a high temperature below 65 degrees Celsius, which is the "most vicious" carcinogen repeatedly mentioned by the media not long ago.
It can be seen that disposable plastic lunch boxes are extremely harmful to the environment and health.
With the further improvement of people's awareness of environmental protection and their own health, more and more people refuse to use fast food boxes made of polystyrene, and some new environmentally friendly lunch boxes have emerged.
The following briefly introduces several environmental protection lunch boxes and their advantages and disadvantages:
1. Carton paper is the most familiar material. "Replacing plastic with paper" naturally became the first scheme that people thought of. Using paper instead of plastic technology, that is, using paper pulp as raw material, molding and drying in the mold to produce disposable tableware. Advantages: Tableware made by this method is named as "environmental protection product" because of its advantages of non-toxicity, easy recovery, renewable utilization and degradation, and it is a good alternative technology for comprehensive evaluation at present.
Disadvantages: If evaluated from the whole process of paper production and use, this technology also has some shortcomings. First, the production of paper pulp needs a lot of forest resources, while China's forest resources are limited, and a large number of trees are cut down to cause soil erosion, which is not in line with China's national conditions; On the other hand, pulp will cause serious water pollution in production, and in some cases the pollution degree even exceeds that of plastic. Therefore, from a macro point of view, the technology of replacing plastic with paper can not completely eliminate environmental pollution, but only advance the pollution of tableware to the pollution of the environment when making lunch boxes.
Moreover, the production cost of paper pulp is high, which makes the price of paper tableware produced with paper pulp relatively high. It is not a perfect scheme to replace plastic with paper.
2. Plant fiber lunch box This technology uses plant fibers, such as straw, straw and bagasse. , to obtain fiber powder, and then mixed with a certain amount of glue or resin, and then injected into the mold for molding at high pressure and high temperature. Advantages: the products produced by this technology have good degradability and rich raw materials. Disadvantages: The disposable tableware produced by this technology does not remove fiber pigment in production (because chemical bleaching will inevitably cause water pollution), and the appearance color of the product is not ideal.
Third, biodegradable lunch boxes biodegradable lunch boxes are relatively advanced environmental protection products. It uses starch as the main raw material, adds annual plant fiber powder and special additives, and makes biodegradable fast food boxes by chemical and physical methods.
Advantages: Because starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally into water and carbon dioxide. In addition, the materials mixed with it are also fully degradable materials, which can be said to have no impact on the environment. The main sources of raw starch can be annual plants, such as corn, potato, sweet potato and cassava.
Disadvantages: the biodegradable lunch box is not perfect, such as the raw materials are mostly food crops, and there are problems to be solved such as mildew prevention.
Disposable lunch boxes worth buying disposable lunch boxes made of three materials.
Disposable lunch boxes are divided into the following three categories according to the source of raw materials, production technology, degradation mode and recycling level:
1. Biodegradable category: such as paper products (including pulp molding and paperboard coating), edible powder molding and plant fiber molding;
2. Photobiodegradable materials: Photobiodegradable plastic (non-foam) type, such as photobiodegradable PP;
3. Materials that are easy to recycle: such as polypropylene (PP), high impact polystyrene (HIPS), biaxially oriented polystyrene (BOPS), natural inorganic mineral filled polypropylene composite products, etc.
In recent years, the disposable fast food box on the market has changed from a foam lunch box to an environmentally friendly lunch box. The original foam lunch boxes has been eliminated because it is not resistant to high temperature and the production process has caused damage to the environment. Instead, plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes and so on.
Among them, plastic has become the mainstream material for manufacturing disposable fast food boxes because of its low toxicity, high melting point, strong plasticity, simple production and low relative cost. Such as PP plastic lunch box, corn starch degradable lunch box, etc. PP polypropylene, with excellent mechanical and thermal properties, is suitable for food packaging. PS polystyrene is rigid and brittle, non-toxic and tasteless, especially suitable for packaging frozen foods such as cakes or salads.
In the past, the foamed lunch boxes in the market have been gradually rejected by consumers because they are not environmentally friendly, and their consumption has decreased. Lunch boxes are divided into environmental protection lunch boxes, mainly including plastic, paper, starch and rare metals.
