食品塑料包装危害人类健康部« Reuse world

作者:企业资讯策划团队 来源:rwfb 发布时间:2010-06-01 浏览:95

慧聪网塑料讯:目前市场上的塑料包装产品范围广泛的食品。中国的一饭盒每年超过120亿时间的使用,每人的平均花费将接近10。从环保产品的监督检验中心和国家抽样结果表明,50%的合格率仍不满意。中央电视台制作了一次性曝光天津饭盒“废物”的过度竞争,超过160倍,是工业碳酸钙大量使用塑料和消费者对这类进口工业石蜡吃。

1。塑料本身有毒
我们对食品容器许可证
,塑料包装有聚酯,聚乙烯,聚丙烯,聚苯乙烯,聚氯乙烯,三聚氰胺,脲醛树脂等。其中,聚乙烯,聚丙烯塑料是安全的,可以用来控制食物。有毒的聚氯乙烯塑料袋多数,包装的食品不应该。 PVC产品在高温环境下,会迅速分解,释放出氯化氢气体。

和PVC中的氯乙烯单体聚合树脂并不会对人体有害,不包含高温食物。
从速度处理环境退化
的聚偏二氯乙烯是最容易处理,其次是聚乙烯材料。最困难的处理聚氯乙烯,化学反应发生时,焚烧会产生氯化氢,二恶英癌症是针对人们的健康。

双酚A(双酚A)是聚碳酸酯塑料食品包装的重要原料,广泛应用于食品包装和化妆品增塑剂。在实验室试验,美国科学家将被放置在幼鼠含有可塑剂化合物双酚A和BBP的环境中,事实证明,这两种物质通过母乳影响乳腺基因雌激素那样的环境。科学家们还发现在加热或塑料陈旧,因为效果尤为突出从零开始。毒理学和学者表示,在激素暴露新生动物合成的化学物质会导致生殖系统和大脑发育障碍,可能对人类胎儿和儿童造成相同的影响。

视察了几乎所有的美国人都被检测到体内含有双酚
答:许多在食品和饮料生产中使用的是透明的聚碳酸酯含有这种物质上的塑料容器的关键。聚碳酸酯在商品生产塑料奶瓶等非常有用的。由于其耐用,轻巧和防摔性能,在双酚A的情况下,一瓶将无法拥有这些特点。除了在用于制造硬塑料,也用于食品袋和饮料瓶的生产。此外,补牙,当用于修复牙齿咬合面的密封层中还含有这类成分,包括用于防止龋齿的一些密封层儿童的臼齿。

South中国科技大学高分子材料研究所教授说,陈之畎专业和塑料中双酚A的使用,深受欢迎。至于瓶子和塑料制品的加热,就不会有这样的挥发性成分,数量多少,以及是否有害的物质,最终人类,所有的实验数据,必要的权力。因为用户的婴儿奶瓶,非常敏感。据他了解,国内目前在这一领域的研究,没有多少人。

2。填料有害

据“新民晚报”报道,在2005年11月,国家质检总局最近随机一次性塑料餐具发现,近50%的产品添加有害填充物,或热油的情况将释放大量的致癌病原体化学物质,严重危害人类健康。快餐食品包装一次性塑料饭盒,食物碗和托盘被添加的废塑料和填充物,当大量热或油脂会释放致癌致病化学物质,严重危害人类健康。一般合格品为聚丙烯金额的70%到80%,其余的填料。不过,一些制造商的成本节约在其产品中,添加滑石粉,碳酸钙填料等,有超过百分之五十,在醋酸严重超标餐具造成的。产品,如遇到高温,有害物质会被溶解在食物,长期摄入会导致这样的制度,以消化不良,胆结石和肝脏疾病。如果餐具含有工业石蜡,还可能致癌,对市民的健康风险是很低的。
在制造过程中
,以提高其粘度,透明度和灵活性,坚持在聚氯乙烯的增塑剂一定的量的增加电影。而增塑剂含有药物化合物,对人体内分泌系统有很大的破坏作用,会破坏人体的雌激素代谢,也容易渗透的食物,尤其是高脂肪食品和熟食品的超市,正是高脂肪的食物。经过长时间的

包裹,食品油脂很容易溶解在包装有害物质,和供暖将加速释放到食品药品复合增塑剂。消费会引起妇女患乳腺癌,新生儿先天缺陷,减少男性精子,甚至精神疾病,如数字。硬脂酸塑料稳定剂是铅的主要组成部分,也是有毒的。这很容易导致盐沉淀,进入人体后会导致铅中毒的储蓄。这些有毒物质和食品一起制止有害人体健康。特别是用PVC塑料中的{zj0}温度,超过50℃?60℃的食物,袋将带领食物。

美国消费者联盟最近测试奶酪包装的包装,发现19种产品被装在7种新鲜奶酪膜内含有高量的增塑剂含有百万分之51 -270单位增塑剂奶酪单位。一个平均的153个单位,远远超过了安全水平。欧洲国家提供了允许范围100万台各载有一个只有18个单位最多。目前,增塑剂在欧洲已被限制在韩国的使用,是明确禁止的。工业碳酸钙

可塑性比较差,过度使用的粉末粘连在一起,这是非常困难的,因此,由软饭盒容易,泄漏和其他质量问题产生的。工业碳酸钙主要是用不同的废物回收的塑料颗粒加工,可能含有细菌,病毒很多,而且还含有苯等致癌物质,芳香基团,严禁在生产中使用的膳食原料的国家框。这个行业的消费容易形成碳酸钙结石,肾结石。工业碳酸钙含有大量的铅,对人体的重金属,消化道,神经系统也有很大的损害。再生塑料,工业石蜡含有对人体的神经系统苯,多环芳烃等有害物质,造血系统也会造成损害。

说,作为工业碳酸钙原料过剩的结果,而且废塑料颗粒粥,伙食和难以形成生产,因此,我们还必须添加一个特殊类型的原料-工业石蜡。工业石蜡含有致癌物多环芳烃等有害物质,因此,国家明令禁止的工业石蜡生产餐盒使用。国家环境保护

产品质量监督检验测试中心的工作人员说,如果饭盒有沉淀溶解在食品,消费者消费的方便,并与不再在饭盒的食物,那么它的溶出量就越大。一般来说,在60度摄氏热的食物,测试在餐盒的浸泡液蒸发人员发现了很多杯白色沉淀物。这些残余物是工业碳酸钙的主要成分外,还含有重金属铅,铬等有害物质,以及含量超出国家标准要求,在超过160次的{zg}水平。国家环境保护

产品质量监督检验测试中心,即弃饭盒部的产品质量监督抽查,有40-50%左右的合格率。这是因为在生产过程中添加大量工业碳酸钙,石蜡和工业废塑料,在蒸发残渣导致失败的饭盒,重金属超过。

3。印刷材料有害

专家特别提醒,使用,熟食,点心等食品供人类直接消费的塑料包装,{zh0}不要使用塑料袋的颜色。因为在塑料着色渗透性和挥发性较强的油,热的时候,很容易渗出的情况时所使用的颜料。如果是有机染料,这也将包含芳烃,对健康有一定的影响。目前市场上出售的塑料奶瓶一些品牌,其色彩模式含重金属会危害健康,消费者必须小心选择。

专家,婴幼儿经常吮吸手指,因此容易被口的瓶子上的有害物质。过量食入铅,铬及其他重金属婴儿和幼儿会出现智力下降,听觉受损,皮肤溃疡等呼吸道。专家说,颜色模式;含有过量重金属瓶上印刷是非常难以判断用肉眼,所以消费者应多注意权威部门检测和彩色图案尽可能买一个小塑料瓶。

4。对再生塑料的使用

消费者不能区分食品和非食品塑料袋,它有一个不合格塑料袋的大量被用于食品包装,严重危害人民健康。目前可以在市场上使用不合格的塑料包装袋,主要是回收塑料制品,甚至从废塑料回收来。 The’90s,卫生部对国家教育部明确规定:“凡塑料餐具,容器,食品包装材料加工,不得使用回收塑料。卫生和医疗设备不能使用更多的再生塑料。” (6月9日- 8)

Part of food plastic packaging harm to human health

Huicong net plastic inquiry: the food currently on the market with a wide range of plastic packaging products. China’s one-time use of lunch boxes every year more than 12 billion, the average spent per person will be near 10. Environmentally friendly products from the National Center of Supervision and Inspection and sampling results showed that the passing rate of 50% is still not satisfied. CCTV produced a one-time exposure Tianjin lunchboxes “waste” excessive competition, more than 160 times, a large number of industrial calcium carbonate, used in plastics and industrial paraffin on such imports by consumers to eat.

1. plastic itself toxic

of our permit for food containers, plastic packaging has polyester, polyethylene, polypropylene, polystyrene, polyvinyl chloride, melamine, urea-formaldehyde resin, etc. . Of these, polyethylene, polypropylene plastics are safe and can be used to contain food. The majority of toxic PVC plastic bags, packaged food should not. PVC products, in high-temperature environment will rapidly decompose, releasing hydrogen chloride gas.

and PVC resin in the polymerization of vinyl chloride monomer is not bad for human health, do not contain high-temperature food.

from the environmental degradation of the speed of treatment, the polyvinylidene chloride are most likely to deal with, followed by polyethylene material. The most difficult to deal with polyvinyl chloride, a chemical reaction occurs when the incineration will generate hydrogen chloride, dioxin cancer were against people’s health.

BPA (bisphenol A)are used in polycarbonate plastic food packaging an important raw material, are widely used in food packaging and cosmetics plasticizers. American scientists in the laboratory test will be placed in juvenile rats contain plasticizers compounds BPA and BBP environment, the facts have proven that these two substances affect the breast through breast-gene estrogen-like environment. Scientists have also found that in the heating or plastic obsolete, since the effect is particularly prominent scratch. Toxicology and scholars said that the chemical substances in the synthesis of hormone exposure in newborn animals will cause the reproductive system and brain developmental disorders, may have resulted in human fetuses and children the same impact.

inspected almost all Americans have been detected in vivo contains bisphenol
A. Many used in the manufacture of food and beverage containers of transparent polycarbonate plastic containing this key on the material. Polycarbonate plastic baby bottle in the manufacture of commodities such as very useful. Because of its durable, lightweight and防摔properties, in the absence of bisphenol A, a bottle will not be able to possess these characteristics. In addition to used in the manufacture of hard plastic, it also used in the manufacture of food bags and drinks bottles. Also, fill a tooth, and when used to repair teeth occlusal surfaces of molars sealing layer also contain such ingredients, including children used to prevent dental caries some sealing layer.

South China University of Technology Institute of Polymer Materials, said Professor Chen Zhiquan professional and bisphenol A in plastics are very popular among the use. As for the bottle and plastic products in the heating would not be such volatile components, the volume number as well as whether the substance harmful to human beings in the end, all necessary authority of the experimental data. Because users are baby bottle, very sensitive. According to his understanding, the domestic current research in this field, not many people.

2. filler harmful

According to “New People’s Daily” reported in November 2005, AQSIQ recent random disposable plastic tableware found that nearly 50% of the product add a great deal of harmful filler, or a case of hot grease will release cancer-causing pathogens chemical substances pose significant dangers to human health. Fast food packaging disposable plastic lunch boxes, food bowls and trays are added a lot of waste plastics and filler, when hot or grease will release cancer-causing pathogens chemical substances pose significant dangers to human health. Commodities in general qualified to account for the amount of polypropylene 70% to 80%, the rest is filler. However, some manufacturers for the cost savings, in their products to add talc powder, calcium carbonate filler, etc. has more than 50 percent, resulting in serious cutlery in superscalar acetate. Products such as encountered in high temperature, harmful substances will be dissolved in food, long-term intake will lead to indigestion, gallstones and liver diseases, such as system. If tableware contains industrial paraffin wax, may also be carcinogenic, the public health risk is very low.

in the manufacturing process in order to increase its viscosity, transparency and flexibility of PVC cling film in an increase of a certain amount of plasticizer. And the plasticizer containing a pharmaceutical compound, which the human endocrine system has a great destructive effect, will disrupt the body’s estrogen metabolism, is also vulnerable to infiltration of food, especially high-fat food and cooked food in the supermarket are precisely the high-fat food . After lengthy

parcels, food oils and fats it is easy to wrap in the dissolved harmful substances, and heating will accelerate plasticizer in the pharmaceutical compound released into the food. Consumption will cause women to develop breast cancer, neonatal birth defects, reduce the number of male sperm, or even mental illness, such as. Plastic stabilizer of stearic acid are the major components of lead, is also toxic. This can easily lead salt precipitation, once entered the body will result in savings of lead poisoning. These toxic substances and food together stop it harmful to human health. Especially the use of PVC plastic, in the best temperature exceeds 50 ℃ ~ 60 ℃ food, the bag will lead into the food.

American Consumers Union recently tested cheese wrap packaging and found 19 kinds of products are packaged in 7 kinds of fresh cheese intramembranous contain high amount of plasticizer, per million units of cheese containing 51 -270 units plasticizer. An average of 153 units, far exceeding the safety limits. European countries are provided to allow the scope of one million units each containing a maximum of only 18 units. At present, the plasticizer in Europe has been restricting the use of, in South Korea was specifically prohibited. Industrial calcium carbonate

relatively poor plasticity, excessive use of powder sticking together, it is very difficult, therefore, produced by the soft lunch boxes easy, leakage and other quality problems. Industrial calcium carbonate is mainly used a variety of waste processed from recycled plastic granules, may contain a lot of bacteria, viruses, but also contain benzene, aromatic group, such as carcinogens, are strictly forbidden country of raw materials used in the production of meal boxes. Consumption of this industry easy to form calcium carbonate gallstones, kidney stones. Industrial calcium carbonate contains a lot of lead, heavy metals on the human body, digestive tract, nervous system also has a lot of harm. Recycled plastics, industrial paraffin containing benzene, polycyclic aromatic hydrocarbons and other harmful substances on the body’s nervous system, hematopoietic system will also cause harm.

added as a result of the excess raw materials of industrial calcium carbonate, but also gruel of waste plastic particles, the production of meals and difficult to shape, therefore, we must also add a special type of raw materials - Industrial paraffin. Industrial paraffin contains carcinogenic polycyclic aromatic hydrocarbons and other harmful substances, therefore, the state prohibited the use of industrial production lunchboxes paraffin. State Environmental Protection

Product Quality Supervision, Inspection and Testing Center staff that if lunch boxes have precipitates dissolved in the food, the easy consumer consumption, and food on the lunch boxes with the longer, then it’s Dissolution of the greater volume. In general, the hot food temperature at 60 degrees Celsius, testing personnel in the浸泡液for evaporation of meal boxes and found a lot of precipitation cup white residue. These residues are the major components of industrial calcium carbonate, but also contain heavy metals lead, chromium and other harmful substances, and the content exceeded the national standard requirements, the highest in more than 160 times. State Environmental Protection

Product Quality Supervision, Inspection and Testing Center, Department of disposable lunch boxes for the product quality supervision and spot checks, with a pass rate of 40-50% or so. This is because in the production process to add substantial industrial calcium carbonate, paraffin wax and industrial waste plastics, resulting in the evaporation residue failed lunchboxes, heavy metals exceeded.

3. printing materials harmful

specifically reminded the experts, using plastic packaging of cooked food, snacks and other food intended for human consumption directly, it is best not to use plastic bags have color. Because the pigments used in coloring plastic permeability and volatile stronger case of oil, when hot, when easy exudation. If it is an organic dye, which will also contain aromatics, has a certain impact on health. Currently on the market to sell some brands of plastic baby bottle, and its color pattern containing heavy metals are hazardous to health, consumers must choose carefully.

experts, infants and young children often suck fingers, so vulnerable to the harmful substances on the bottle into the mouth. Excessive ingestion of lead, chromium and other heavy metals in infants and young children will appear intellectual decline, hearing impairment, skin and respiratory tract such as ulcers. The expert said that the color pattern printed on the bottle containing excessive heavy metals are very difficult to judge with the naked eye, so consumers should pay more attention to the detection of authoritative departments, and color patterns as far as possible to buy a small plastic bottle.

4. the use of recycled plastics

consumers can not distinguish between food and non-food plastic bags, it has a considerable number of unqualified plastic bags being used for food packaging, seriously endanger people’s health. Currently available in the market to use unqualified plastic packaging bags, mainly Recycling plastic products, or even come from recycling of waste plastic. The’90s, the Ministry of Health on the country expressly provides: “Where the processing of plastics utensils, containers, food packaging materials, shall not use recycled plastic. Hygiene and medical equipment are not allowed to use more recycled plastic.” (06-9 - 8)
