不是所有的食品包裝袋都能用裝食品

不是所有的食品包裝袋都能用裝食品,其中聚氯乙烯塑料就是有毒的品種;聚氯乙烯樹脂無毒性,但在制作塑料的過程中加入了增塑劑鄰苯二甲醇二丁酯或鄰苯二甲酸二辛酯,所以生產出來的食品包裝袋就有毒性。
Not all food packaging bags can be used to hold food, in which PVC plastic is a toxic variety; PVC resin is non-toxic, but the plasticizer dibutyl phthalate or dioctyl phthalate is added in the process of making plastics, so the food packaging bags produced are toxic.
另外,有些塑料袋制品中加入了穩定劑,而這些添加的穩定劑主要是硬脂酸鉛,這樣生產出來的食品包裝袋是有毒性,這種鉛鹽極易析出,一旦進入人體就會造成集蓄性鉛中毒,所以裝食品時要用專用的食品袋,絕 不可亂用。特別是下類情況生產的食品包裝袋更要分清楚。
In addition, some plastic bag products are added with stabilizers, and these added stabilizers are mainly lead stearate. The food packaging bags produced in this way are toxic. This kind of lead salt is very easy to separate out, and once it enters the human body, it will cause accumulated lead poisoning. Therefore, special food bags should be used when loading food, and must not be used indiscriminately. In particular, the food packaging bags produced in the following situations should be clearly distinguished.

1、聚氯乙烯制品與乙醇乙醚等溶劑接觸會析出鉛,所以用聚氯乙烯塑料制品存放含酒精類食品是很不合適的;
1. It is not suitable to store alcoholic food with PVC plastic products because lead will precipitate when PVC products contact with ethanol, ether and other solvents;
2、聚氯乙烯遇含油食品時其中鉛就會溶入食品,所以很不適宜包裝含油食品。
2. When PVC meets oily food, lead will dissolve into food, so it is not suitable for packaging oily food.
3、聚氯乙烯塑料使用溫度高于50℃時就會有HC緩慢析出,這種氣體對人體健康有害。
3. When the temperature of PVC plastic is higher than 50 ℃, HC will be released slowly, which is harmful to human health.
4、廢舊塑料回收再制品,因原料來源復雜難免帶有有毒成分,也不可作食品包裝袋的制作原料。
4. Because of the complex source of raw materials, waste plastic recycling products inevitably contain toxic ingredients, and can not be used as raw materials for food packaging bags.
