People often use a variety of plastic bags to contain food, storage items and garbage in their daily life, but plastic bags not only release harmful gases, especially when they are filled with cooked food, they often deteriorate, so as to release various harmful substances to human body, especially children, because they are in a critical period of growth and development, the impact is particularly prominent. Learn to identify plastic bags, not only to make the best use of everything, but also to avoid unnecessary injury.

有顏色的塑料袋大都使用回收料制作而成，在重新合成塑料袋時都會經過染色，這類塑料袋會含有各種有害物質，特別是黑色塑料袋，這類塑料袋不適合盛裝食品等。

Most colored plastic bags are made of recycled materials. They will be dyed when they are re synthesized. Such plastic bags will contain various harmful substances, especially black plastic bags, which are not suitable for containing food.

透明塑料袋主要有聚乙烯（PE）塑料袋和聚氯乙烯（PVC）塑料袋，盛裝食品的主要由PE制成，而PVC本身也沒有毒性，但在加工過程中根據用途不同，往往會添加各種添加劑，從而產生毒性，鑒別時PE由于密度較水小，沉在水底會浮上來，而PVC密度較水要大，沉在水底不會浮起來，通過沉在水中可以將兩者區分開來，同時PE易于燃燒，火焰呈黃色，PVC不易燃燒，燃燒是火焰呈綠色，同時有刺激性氣味。目前早餐店用的一次性透明塑料袋大多是PVC塑料袋，相關資料顯示，PVC塑料袋在溫度超過50度時就會釋放出重金屬等有害物質，超過80度時就會發生溶解，同時酒精和油脂會溶解PVC中的有害物質，所以也不適宜盛裝此類食品。

Transparent plastic bags mainly include polyethylene (PE) plastic bags and polyvinyl chloride (PVC) plastic bags. The food is mainly made of PE, and PVC itself has no toxicity. However, in the process of processing, various additives are often added according to different purposes, resulting in toxicity. In the identification, PE will float on the bottom of the water due to its lower density, while PVC will float on the bottom of the water due to its higher density It will not float up, and can be distinguished by sinking in water. At the same time, PE is easy to burn, the flame is yellow, PVC is not easy to burn, the flame is green, and there is an irritant smell. At present, most of the disposable transparent plastic bags used in breakfast shops are PVC plastic bags. According to relevant data, when the temperature of PVC plastic bags exceeds 50 degrees, heavy metals and other harmful substances will be released, and when the temperature exceeds 80 degrees, they will dissolve. At the same time, alcohol and grease will dissolve the harmful substances in PVC, so they are not suitable to contain such food.

即使是食品級塑料袋也并非都可以在高溫環境下使用，同樣會有塑料制劑溢出，不利于人體健康，而此類塑料袋即使提供商家也很難向普通消費者說明，到底耐多少度的高溫，而消費者也很難驗證自己所用塑料袋到底能耐多少度高溫，所以更穩妥的辦法還是選用玻璃或陶瓷制品來盛裝各類食品。

Even food grade plastic bags can not be used in high temperature environment, and there will also be overflow of plastic agents, which is not conducive to human health. However, even if such plastic bags are provided by businesses, it is difficult to explain to ordinary consumers how much high temperature they can withstand, and it is also difficult for consumers to verify how much high temperature they can withstand. Therefore, the safest way is to choose glass Glass or ceramic products to contain all kinds of food.

一次性塑料袋的危害是什么？

What are the hazards of disposable plastic bags?

1、塑料袋本身會釋放有害氣體。特別是熟食，用塑料袋包裝后，常常會變質。變質的食品對兒童健康發育的影響尤為突出。

1. Plastic bags themselves release harmful gases. Especially cooked food, after being packed in plastic bags, often deteriorates. The effect of spoiled food on children's healthy development is particularly prominent.

2、塑料袋回收價值較低，在使用過程中除了散落在城市街道、旅游區、水體中、公路和鐵路兩側造成“視覺污染”。

2. The recycling value of plastic bags is relatively low, which causes "visual pollution" in the process of use except for scattered in urban streets, tourist areas, water bodies, roads and railways.

3、廢塑料隨垃圾填埋進入生活垃圾中的廢塑料制品如果將其填埋，200年的時間才能將其降解。而且，塑料袋以石油為原料，不僅消耗了大量資源，還不能被分解，埋在地下會污染土地、河流。

3. The waste plastic products which enter into the domestic garbage with the landfill can be degraded in 200 years if they are landfilled. Moreover, plastic bags, which use oil as raw material, not only consume a lot of resources, but also can not be decomposed. Buried underground will pollute land and rivers.

4、影響農業發展。廢塑料制品混在土壤中不斷累積，不僅會占用大量土地，而且被占用的土地長期得不到恢復，影響土地的可持續利用，影響農作物吸收養分和水分，導致農作物減產。

4. Affecting agricultural development. The continuous accumulation of waste plastic products mixed in the soil will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land, affecting the absorption of nutrients and water by crops, leading to crop yield reduction.

5、焚燒塑料袋會產生有毒氣體，會使一小部分土地不能種植，所以都選在沒有人住的地方焚燒。焚燒塑料袋產生的濃煙里會產生致癌物質，對人的身體極為不利。

5. Burning plastic bags will produce toxic gases, which will make a small part of the land unable to be planted, so they will be burned in places where no one lives. The smoke produced by burning plastic bags will produce carcinogens, which is extremely harmful to people's health.

6、對動物生存構成威脅。拋棄在陸地上或水體中的廢塑料制品，被動物當作食物吞入，導致動物死亡。這樣的事在動物園、牧區、農村、海洋中屢見不鮮。

6. It is a threat to the survival of animals. Waste plastic products discarded on land or in water are swallowed by animals as food, resulting in animal death. Such things are common in zoos, pastoral areas, rural areas and oceans.

7、此外，鄰苯二甲酸類衍生物中很多是脂類，不易溶于水，但能溶于加溫過的食品或脂肪性食品。因此特別提醒大家，如果用塑料袋作食物包裝材料，使用時要特別小心，盡量不要用其來盛裝熱飯菜等食物。

7. In addition, many of the phthalate derivatives are lipids, which are insoluble in water, but soluble in heated food or fatty food. Therefore, I would like to remind you that if you use plastic bags as food packaging materials, you should be very careful when using them, and try not to use them to contain hot food and vegetables.

8、在農貿市場上，攤主往往用很厚的黑色塑料袋盛裝宰殺的禽魚等食品。這種塑料袋是經過多次回收再加工得產品，內含多種有毒的溶解劑及其他有毒物，很容易摻入到剛宰殺的動物體內，對人體也會造成相應的損害。

8. In the farmer's market, stall owners often use thick black plastic bags to hold slaughtered poultry, fish and other food. This kind of plastic bag is a product that has been recycled and reprocessed for many times. It contains a variety of toxic dissolving agents and other poisons. It is easy to be mixed into the newly slaughtered animals and will cause corresponding damage to human body.
