不是所有的食品包装袋都能用装食品
发布于:2021/06/08 不是所有的食品包装袋都能用装食品,其中聚氯乙烯塑料就是有毒的品种;聚氯乙烯树脂性,但在制作塑料的过程中加入了增塑剂邻苯二甲醇二丁酯或邻苯二甲酸二辛酯,所以生产出来的食品包装袋就有毒性。
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稳定剂,而这些添加的稳定剂主要是硬脂酸铅,这样生产出来的食品包装袋是有毒性,这种铅盐极易析出,一旦进入人体就会造成集蓄性铅中毒,所以装食品时要用专用的食品袋,绝 不可乱用。特别是下类情况生产的食品包装袋更要分清楚。
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、聚氯乙烯制品与乙醇乙醚等溶剂接触会析出铅,所以用聚氯乙烯塑料制品存放含酒精类食品是很不合适的;
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时其中铅就会溶入食品,所以很不适宜包装含油食品。
2. When PVC meets oily food, lead will dissolve into food, so it is not suitable for packaging oily food.
3、聚氯乙烯塑料使用温度高于50℃时就会有HC缓慢析出,这种气体对人体健康有害。
3. When the temperature of PVC plastic is higher than 50 ℃, HC will be released slowly, which is harmful to human health.
4、废旧塑料回收再制品,因原料来源复杂难免带有有毒成分,也不可作食品包装袋的制作原料。
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.
