什么样的塑料袋是无危害的?

发布日期:2019-09-23 作者:365体育娱乐 点击:

  塑料袋有很多种,但可以直接触摸或拿在食物上的塑料制品,尤其是塑料袋,只由聚乙烯和聚丙烯制成。这两种塑料在制作食品包装袋时不能添加添加剂,所以基本上是无毒的。他们被允许使用,但是他们更贵。
  There are many kinds of plastic bags, but plastic products that can be directly touched or held on food, especially plastic bags, are only made of polyethylene and polypropylene. These two kinds of plastics can't add additives when making food packaging bags, so they are basically non-toxic. They are allowed to use by the state, but they are more expensive.
  一般非接触食品使用的塑料是以聚氯乙烯等原料。聚氯乙烯价格低廉,易上色,色泽鲜艳,不易变形,易加工制造,可添加多种添加剂。这种塑料有广泛的用途,如工业和农业塑料,家庭用品和雨衣,凉鞋,玩具等。
  In general, the plastic used in non-contact food is made of polyvinyl chloride and other raw materials. Polyvinyl chloride is cheap, easy to colour, bright color, not easy to deform, easy to process and manufacture, can add a variety of additives. This plastic has a wide range of uses, such as industrial and agricultural plastics, household goods and raincoats, sandals, toys and so on.
  聚氯乙烯(PVC)是我国生产效率高的塑料。聚氯乙烯的毒性来源有两个方面,它是氯乙烯塑料本身的质量,完整的聚氯乙烯聚合是高分子化合物,人类和动物不能吸收,基本上无毒,其毒性取决于自由氯乙烯单体的毒性和致癌性,没有完成聚合。二是在聚合过程中添加的添加剂的毒性,许多工业添加剂都是有毒的。
  Polyvinyl chloride (PVC) is the most efficient plastics in China. There are two sources of toxicity of polyvinyl chloride. It is the quality of vinyl chloride plastics. Complete polyvinyl chloride polymerization is a high molecular compound, which can not be absorbed by human and animals. It is basically non-toxic. Its toxicity depends on the toxicity and carcinogenicity of free vinyl chloride monomers, and the polymerization has not been completed. Second, the toxicity of additives added in the process of polymerization, many industrial additives are toxic.

  塑料袋批发添加剂高温可以溶解出聚氯乙烯塑料,在20世纪60年代广泛应用于餐具中,曾多次出现用这种塑料碗蒸饭和急性中毒事件,所以从20世纪70年代起被禁止用于食品包装材料。80年代以后,生产技术的进步使氯乙烯单体急剧下降,聚氯乙烯塑料再次被用于食品包装材料。但聚氯乙烯,可用于食品包装和一般聚氯乙烯是不同的,它有严格的标准和无毒无害的原料、配方、添加剂、辅助剂等,并严格限制使用限制,如果可以用于饮用水管的垫圈和瓶盖,但不允许直接接触食物,不能有更多的颜色。
  The wholesale additive of plastic bags can dissolve polyvinyl chloride plastics at high temperature. It was widely used in tableware in the 1960s. Steaming rice with this plastic bowl and acute poisoning incidents occurred many times, so it has been forbidden to be used in food packaging materials since the 1970s. After the 1980s, the progress of production technology led to a sharp decline in vinyl chloride monomers, and polyvinyl chloride plastics were once again used as food packaging materials. However, polyvinyl chloride can be used in food packaging and general polyvinyl chloride is different. It has strict standards, non-toxic and harmless raw materials, formulations, additives, assistants, etc. It also strictly restricts the use of restrictions. If it can be used in washers and bottle caps of drinking water pipes, but it does not allow direct contact with food, it can not have more colors.
  生产许多稳定剂、增塑剂时需要添加聚氯乙烯,长时间接触含有油脂的食品,尤其是夏季温度较高时,这些添加剂会溶解,而氯乙烯也会溶解,进入食品中。
  In the production of many stabilizers and plasticizers, polyvinyl chloride (PVC) needs to be added, and these additives will dissolve when exposed to food containing grease for a long time, especially when the temperature is high in summer, and vinyl chloride will also dissolve into food.
  聚氯乙烯塑料一般不会引起急性毒性,其毒性主要是慢性毒性和致癌性。聚氯乙烯的慢性毒性是肝毒性、脑变性、间质性肺炎、肾病,它还可引起肝血管瘤和癌症。
  Polyvinyl chloride plastics generally do not cause acute toxicity, its toxicity is mainly chronic toxicity and carcinogenicity. The chronic toxicity of polyvinyl chloride is hepatotoxicity, brain degeneration, interstitial pneumonia and nephropathy. It can also cause hepatic hemangioma and cancer.
