Disposable lunch box can be loaded with boiled water
Disposable lunch box can be loaded with boiled water, disposable lunch box because of the convenience, free of charge, is very suitable for the rapid pace of life. So people are very favorite and often use it, then we use the disposable lunch box can be loaded with boiled water?
Disposable lunch box can be loaded with boiling water 1Hotel disposable lunch box can boil water hot
According to the regulations, the main raw material for the production of lunch boxes is polypropylene, the content of 80% or so; industrial calcium carbonate as a filler, the content can not be more than 20%. Polypropylene plasticity, the production of lunch boxes using good strength, not easy to deform. But industrial calcium carbonate is a stone powder, plasticity is relatively poor, excessive use of powder is difficult to bond together, therefore, the production of lunch boxes are prone to softening, leakage and other quality problems.
The test results are worrying, disposable food and drink containers there are very serious safety and quality problems, mainly, there are large problems with the health performance, due to the addition of a large number of calcium carbonate in the production of raw materials, industrial paraffin, recycled waste, resulting in the product of the evaporation of residue (n-hexane, acetic acid) seriously exceeded the standard. In addition, the use performance is poor, the weight is unqualified, the volume deviation is large, and there is leakage. There is also unqualified degradation performance, some companies will be filled with calcium carbonate products as degradation products, and such products can not really degrade.
Disposable lunch boxes not only in the production and use of the hazards brought to us, in the treatment will also bring more new problems. At present, the treatment of foam lunch boxes are generally used to incinerate, buried, thrown away. If buried, the foam lunch box in the environment for about 200 years to decompose, but also impede the growth of plant roots, may also contaminate groundwater.
Disposable lunchboxes produce harmful toxins and carcinogens dioxins after heating, which are extremely carcinogenic. Disposable lunch boxes can not take the boiling water hot Oh, if you take the boiling water hot will also decompose harmful substances, a long time may cause cancer. If the number in the triangle at the bottom of the lunch box, if it is 5, it can withstand 100 degrees of boiling water. But disposable lunch boxes try not to use boiling water.
Can a disposable lunch box hold boiling water2Some can, some can not. Because different materials made of plastic lunch box temperature resistance are different.
The most heat-resistant is polypropylene (PP) can withstand 140 ℃, followed by polyethylene (PE) can be heat-resistant 110 ℃, and polystyrene (PS) can only be heat-resistant to 90 ℃. Currently marketed microwave oven special plastic lunch box, mainly made of PP or PE, such as the temperature exceeds their thermal limit, the plasticizer has the possibility of release, so you should avoid long-term use of high-temperature heating plastic lunch box to turn hot food.
Plastic disposable lunch boxes are best avoided with boiling water. Plasticizer in disposable plastic bowls and cups are easy to melt and release when hot, and long-term use is not good for health. Plasticizer will interfere with the human endocrine system, especially on the male reproductive system has a great impact. Plastic containers with PET logo, heating more than 70 ℃ may precipitate plasticizer; does not meet the PET standard material, precipitation of the temperature point may be lower.
Expanded:
Plastic products have a shelf life.... Experts warn that plastic products will age after the expiration date, discoloration, brittle situation, such as the use of plastic boxes found yellow or no longer transparent, should be replaced as soon as possible. Aging plastic will also release substances that may be harmful to the human body.
"The most critical use of plastic products is the temperature conditions, in general, as long as the product labeled temperature environment to use, the product will not decompose toxic substances." Some experts pointed out that the service life of plastic products is generally 3 to 5 years, if used frequently, one to two years to replace the best.
Disposable lunchboxes can be loaded with boiling water3 Disposable lunchboxes are able to be heated? The main raw material for the production of lunch boxes is polypropylene, with a content of about 80%; industrial calcium carbonate as a filler, with a content of no more than 20%. Polypropylene's plasticity is strong, the production of the lunch box to use the strength is very good, not easy to deformation. But industrial calcium carbonate is a stone powder, plasticity is relatively poor, excessive use of powder is difficult to bond together, therefore, the production of lunch boxes are prone to softening, leakage and other quality issues. Soft touch, gently tear on the break, there is a strange smell, is these unqualified disposable lunch box **** the same characteristics. Soft touch, so that the lunch box with a very inconvenient, and even cause meals when food or soup and things like spillage; and odor, is the production of lunch boxes in the material contains toxic substances in the obvious signs. Disposable lunch boxes are foamed plastic tableware, the food if more than sixty-five degrees, will precipitate its own toxins with the invasion of food, like plastic bags can not meet the same high temperature, and if the process of processing control is not good, the toxicity will be even greater, with the Such a lunch box to eat the equivalent of a chronic poison, although the toxicity of the weak, but the long-term use of the liver, kidneys, and so on, will cause damage. These lunchboxes are the equivalent of a chronic poison. The use of fluorescent whiteners in the processing of food and food-related products is strictly prohibited, because once absorbed into the human body, fluorescent whiteners can destroy cellular proteins, which is one of the potential carcinogenic factors. At the same time, fluorescent whiteners contain benzene ring organics, which can weaken the healing ability of wounds. Even if the new material production of disposable plastic tableware there are safety hazards, more than 100 degrees Celsius, disposable foam lunch boxes will be deformed, especially containing oil food, or the use of microwave heating, unpolymerized styrene monomer will enter the human body, resulting in poisoning. Not only that, the plastic itself will be melted and eaten into the human body, can not be decomposed, the accumulation of life-threatening. From the above, we can see that the disposable lunch box can not be heated, if heated, there will be deformation of the phenomenon, but also lead to a number of toxic substances into the meal, if you often eat these foods, it is easy to lead to some of the symptoms of the body, and serious and even life-threatening, so it is best not to use a disposable lunch box, and do not heat. What are the hazards of disposable tableware Disposable lunchboxes are mainly composed of polystyrene, ethylene and other polymer compounds, which are difficult to decompose, toxic, and buried in the soil for a hundred years will not be degraded and other characteristics. Because it is difficult to degrade, it will also cause new pollution to the environment. It is white pollution, in the burning will release a lot of toxic gases, and two hundred years do not decay, causing serious harm to the environment. At the same time, due to some of the foaming tableware raw materials in the concentration of harmful substances exceeded the standard, the process of processing technology control is not good, the use of the process temperature is too high, will lead to tableware "with poison". Generally qualified disposable plastic tableware, the amount of polypropylene to account for 70% to 80%, the rest for the filler. But many manufacturers in the product added talc, calcium carbonate, etc. was more than 50%, which led to the tableware in the acetic acid seriously exceeded the standard. A bubble of hot water, microwave oven a turn or even a slightly higher temperature of the food, harmful substances will be dissolved in the food, long-term intake will lead to indigestion, gallstones, and liver system lesions. If the tableware contains industrial paraffin, it may even cause cancer. Above detailed to give you the harm of disposable tableware on the human body, this thing in the convenience of bringing people at the same time, for the body also has a harm, and the harm is not only so, disposable tableware for the environment, the impact of the obvious, damage to the environment, the main thing is to throw, as well as the material will not be the decomposition of the characteristics of the hundred years, is the reason for pollution of the environment.
