食品塑料袋无QS标志，不含氯也可威胁健康
Plastic bags of food without QS mark, no chlorine can also be a threat to health
记者调查发现，食品用塑料袋存在诸如无QS标志、伪造QS标志、掺入再生垃圾塑料等问题。没有QS标志的白色塑料袋能不能用？和有QS标志的塑料食品用袋有何不同？本报前期曾和青岛大学化工学院创新实验项目组合作进行了银耳中硫磺含量、巧克力中代可可脂鉴别的实验。记者4月 7日再次来到青岛大学化工学院创新实验项目组，对记者带去的塑料袋样品进行了实验。
The reporter investigates discovery, food plastic bag as no QS mark, forged QS logo, blended renewable waste plastic problems. No QS mark white plastic bags can be used? And a sign QS plastic food bags differ? The earlier period once and Qiingdao University Institute of chemical technology innovation experiment project group cooperation in the sulfur content in Tremella, chocolate cocoa butter identification experiment. Reporter in April 7th once again came to the Qiingdao University Institute of chemical technology innovation experiment project group, told the reporter to plastic bags samples were experiment.
现状无QS标志塑料袋到处有
Status no QS mark plastic bags everywhere
"俺这就叫环保袋，用这个盛吃的绝对没问题。"南京路一家包子铺老板说。记者调查发现，除正规超市外，路边小摊、小饭店 、便利店，装食品的用袋几乎找不到QS标志的影子。
" I call it the environmental protection bag, the Sheng had absolutely no problem. " Nanjing road is a steamed stuffed bun shop boss. The reporter investigates discovery, in addition to regular supermarkets, roadside stalls, restaurants, convenience stores, food containing bag almost can not find a sign QS shadow.
路边小摊、小饭店 、便利店没有QS标志的白色塑料袋和标有QS标志的塑料食品用袋有啥不同？没有QS标志的白色塑料袋到底能不能用？记者心中充满了疑问。
Roadside stalls, restaurants, convenience stores have no QS mark white plastic bags and marked with a QS sign of plastic food bags have what different? No QS mark white plastic bag it can be used? The reporter was full of questions.
"俺这是批发的，不到一分钱一个。"上述老板说。记者翻开一捆新的塑料袋，用手在塑料袋上摸了摸，手上沾了一些白色的粉末状物质。这些白色粉末是什么？热腾腾的包子、油条用这种白色塑料袋装会不会产生有害物质？
" I this is wholesale, not a penny a. " The boss said. The reporter opens a bundle of new plastic bags, hand in plastic bags to touch hands, some white powdery substance. The white powder is what? Hot buns, fried dough sticks with the white plastic bags will not produce harmful substances?
"塑料袋大体分为两种，一种以聚乙烯为原料，一种以聚氯乙烯为原料。食品用塑料袋要求以聚乙烯为原料，聚氯乙烯的用途大多是电线外皮、光纤外皮、包装纸等。"青岛大学化工学院创新实验项目组孙老师说。
" Plastic bags can be divided into two kinds, one kind of polyethylene as raw materials, a polyvinyl chloride as raw material. Food plastic bags to polyethylene as raw material, PVC uses mostly cable jacket, the sheath of the optical fibers, wrapping paper. " Qiingdao University Institute of chemical technology innovation experiment project group sun speaks.
疑问塑料袋可能存在啥问题
Doubt plastic bags may exist what problem
没有QS标志的白色塑料袋有没有问题？有的话又有哪些问题？"首先，这种塑料袋是不是聚乙烯制造的应该在实验中得到印证，如果连材料都不是聚乙烯的话，那根本不能盛放任何食品。因为聚氯乙烯高温时容易有有害物质产生，甚至连制造的过程中都会释放。有毒物质随食物进入人体后，可能引起乳癌、新生儿先天缺陷等疾病。"孙老师称，"其次，即使是以聚乙烯为原料，还要确定是否存在掺入回收再生垃圾塑料，回收塑料混杂着一些杂质，比如粉尘等，倘若回收的包装膜、包装瓶曾装过如化肥、农药之类的有毒、有害物质，简单的洗涤是不可能全部清除干净的。"
No QS mark white plastic bags have a problem? So what problem? " First of all, the plastic bag is it right? Polyethylene manufacturing should be confirmed in experiments, even if the material is polyethylene, that cannot contain any food. Because PVC high temperature easy to harmful substances produced, even the manufacturing process will release. Toxic substances enter the human body along with food, may cause cancer, birth defects and other diseases. " Mr. Sun said," then, even with polyethylene as the raw material, but also determine the existence of incorporation of recycling waste plastics, recycled plastics mixed with impurities, such as dust, if the recycling of packaging film, packaging bottle had contained such as fertilizers, pesticides, toxic, harmful substances, simple washing is not may all cleaned up. "
"就算是用聚乙烯制作，并且印有 QS标志，也可能存在问题。QS标志可以自己印刷，有QS标志的食品用袋也不一定安全。"一位印刷业内人士说。
" Even with polyethylene, and a QS mark, may also exist problems. QS mark can be printed, a sign QS food bags are not necessarily safe. " A printing industry.
