Shanghai: bottled water tastes plastic. 60% of food packaging has hidden dangers.

translucent (milky white) high density polyethylene (HDPE) bottles are mostly used to hold 1 gallon of pure water.

transparent plastic bottles are called polyester bottles (PET), which are relatively heat-resistant.

recently, many readers called our newspaper 962288 to question -

How can you drink bottled water with plastic flavor

the staff of Shanghai food and Drug Administration reminded consumers: "the standard of purified water is colorless and tasteless. If there is a taste, consumers should not drink it, please report it to the relevant departments in time."

although relevant departments remind consumers to enhance their awareness of self-protection, mastertop 1327 ⑵ 0dB is an ideal solution to provide an environment with beauty, walking comfort and minimum noise level. We are more looking forward to knowing the "intimate clothes" of food; We hope that the relevant departments can effectively supervise and let consumers worry less about themselves

"how can barreled purified water taste like plastic?" Recently, many readers called our newspaper 962288. If a consumer drinks plastic, it means there is polarity problem in the wiring; If the pure water with reduced polarity instigates the light on, will it be "injured"

in order to find out, this newspaper has conducted many investigations in recent days, both happy and worried. Fortunately, in September this year, the General Administration of quality supervision, inspection and quarantine launched the market access system for 39 products such as plastic packaging, containers and tools for food, and relevant departments began to pay attention to this issue; The worry is that due to the difficulty of supervision and the lack of scientific research means, there is no way to "plastic taste" for the time being

"plastic smell" is exposed

on August 10, Miss Wang, who lives in Hongkou District, bought a bucket of 4-liter pure water at a supermarket on Quyang Road. She felt a little peculiar smell when drinking it. She didn't care, thinking that there was something wrong with her taste. Her husband works in the food industry and is sensitive to taste. After coming back, he tasted it and said it was raw plastic

the manufacturer sent a staff member to provide door-to-door service that day. After looking at the production batch, he knew the reason without tasting it

"several customers have reported." The staff member, surnamed Quan, is a salesman in this area. She explained: "the weather is too hot, and the car goods may be exposed to the sun during transportation, so it smells a little."

the two sides had differences on the settlement of claims. Miss Wang asked for compensation for 1 box, and the manufacturer said that the maximum compensation was 3 bottles. Now Miss Wang was angry and had to ask why. On September 6, she complained to the Hongkou District food and drug administration

chief Liu of the comprehensive business department of Hongkou District food and drug administration was a little embarrassed. First, this bucket of water was produced on August 3, and second, there was only half a bottle left. Even if it was found, it could not explain the problem. However, they immediately came to a supermarket on Quyang Road mentioned by Miss Wang and removed all the 4-liter pure water from the cabinet for investigation. The inspector opened a bottle of water on August 24. Under the hint of "pay attention to taste, especially plastic taste", six staff members tasted it respectively, and only one felt: "it's a little plastic taste."

at this point, this complaint has come to an end for the time being. Miss Wang reluctantly accepted the manufacturer's compensation plan

similar complaints are by no means cases

in the 315 complaint, the complaint about "plastic smell" is not just a case. Zhang Fuqin, a consumer in Shanghai, Wang Zhanfeng, a consumer in Beijing, and Fang Yu, a consumer in Guangdong, all have the same "experience" as Miss Wang

on September 8, Wang Zhanfeng bought a bucket of 4-liter natural water from Nongfu mountain spring at the urban and Rural storage supermarket in Beijing, He said, "the can body was marked to be produced on August 3, 2006. When I opened the lid, I smelled a smell, and my tongue was astringent after drinking. It was extremely difficult to drink. Because it was a bottle that was opened just before going to bed at night, I didn't drink water all night. I had always bought this kind of drinking water before, and there was never a problem. It is estimated that there is something wrong with the bottle, and I strongly request an explanation." The final result of these complaints is that the manufacturer still makes some compensation

a good plastic bucket should be heat-resistant

for the "plastic smell" in the water, the staff of Nongfu Shanquan Shanghai Office explained: "after analysis, our technicians believe that it may be caused by the high temperature environment for a long time during transportation and storage. Our company will strengthen the sun protection and heat insulation measures during storage and transportation to reduce the possibility of odor."

at ordinary times, the transparent plastic bottles we see in the market are called polyester bottles (PET), while the 4-liter containers of Nongfu mountain spring and one gallon containers in Yanzhong are made of translucent (milky white) high-density polyethylene (HDPE) bottles

in the investigation, it was found that this HDPE bottle seemed to be particularly afraid of "heat". Some manufacturers have specially indicated precautions on the packaging, such as "shuisenhuo" indicating "avoid direct sunlight and high temperature", Linbi indicating "store in a cool and refreshing place, avoid direct sunlight", and Yanzhong indicating "disposable use, no recycling". The same below)

several materials experts questioned the so-called "plastic barrels are afraid of high temperature". Ms. Fu from the Institute of organic chemistry of the Chinese Academy of Sciences said, "plastic bottles that meet national standards have a certain heat resistance index. How can the high temperature during transportation make water produce plastic taste?"

"the processing technology and method of plastic bottles have a set of national standards, and they must meet the relevant indicators before leaving the factory. Plastic bottles that meet the national standards must be safe and hygienic." Ms. Fu said

yuan Huilin, an associate professor of Polymer Engineering Department of Beijing University of chemical technology and a director of China Engineering Plastics Industry Association, said: "whether it's polyester (PET) or high-density polyethylene (HDPE), it doesn't have any flavor in itself. If it produces smell, it's worth discussing." Professor Yuan also pointed out that plastic containers that meet national standards are non-toxic and harmless, and they will not produce plastic taste. "In my opinion, the taste is not necessarily produced by the bottle itself, but may also be some molecules in the film and solvent."

the staff of the Municipal Food and drug administration also disagreed with the statement that "high temperature causes the release of peculiar smell from plastic bottles": "of course, there are many factors that cause the peculiar smell of purified water, but such a statement is indeed questionable."

60% of the packaging materials have hidden dangers

a staff member of the Municipal Food and Drug Administration said: "in fact, due to the limited technical capacity, we do not know much about plastic packaging materials, and how to supervise, manage and detect them is not very clear."

"about 60% of food packaging materials in China have potential safety hazards, and more people are still using plastic products of unknown origin, which will bring harm to health." Experts from the China Packaging Resources Comprehensive Utilization Committee said that the standard of plastic containers for food in China lags behind. One reason is that relevant research lags behind, and consumers often think of "reminding" after problems occur

the staff of the Municipal Food and Drug Administration said, "the research on plastic containers and packaging involves many marginal disciplines, and developed countries are far ahead of China in this regard. For example, PVC fresh-keeping film, after the foreign report was published, we knew that there was a problem, and then launched an inventory in China."

according to a report from the quality inspection department, "for a long time, people generally believe that the food safety problem mainly lies in the food itself. However, the experience of food safety supervision in developed countries and the food safety events in China in recent years show that food contact materials have a significant impact on food safety."

according to the quality inspection department, after the implementation of the market access system, the vast majority of small and medium-sized plastic products enterprises will be rejected by strict standards. Garbage lunch boxes and waste milk bottles may be far away from our lives. However, the supervision, management and research of plastic products cannot be relaxed because of the implementation of the access system

[focus link] plastic food packaging caused trouble

■ in 2005, due to the ban in China, Japan and South Korea PVC food preservative film entered China on a large scale, and was banned after finding the harm

■ on November 5, 2005, a consumer in Jinan found a pungent plastic smell when eating a well-known brand of milk Baili bag. The company said that when the bagged milk is heated to a certain temperature, the plastic bag itself must have a smell

■ at the beginning of 2006, the general survey of quality inspection departments found that there are more than 3700 production enterprises of plastic packaging and other products for food in China, including more than 1100 small enterprises with less than 10 people, accounting for nearly 1/3 of the total number of enterprises

■ in May 2006, Professor lishuguang of the school of basic medicine of Tongji University said, "if edible oil is packed in plastic barrels, plasticizers harmful to human body will be dissolved in the edible oil." People concerned pointed out that the wide range of plasticizers, the large area of pollution and the number of people affected are better than pesticides and DDT

■ in May, 2006, the "problem bottle" made of waste CDs was exposed, and the toxic substance phenol of the sewage treatment plant of Jianshe TONG1 in the material seriously exceeded the standard

[Focus] poor quality plastic packaging is harmful to health

the European Union passed a formal resolution in 1999 to strictly limit the content of plasticizers in baby pacifiers and other products within the scope of EU Member States

EU has strict restrictions on the residues of harmful substances in food contact materials. Because food contact materials have an important impact on food safety, although inferior food contact materials do not harm consumers' bodies in a short time like viruses and bacteria, in the case of long-term repeated use, toxic and harmful substances will lead to chronic poisoning and endanger the growth and development of children and adolescents

if poor quality lunch boxes encounter heat or grease, they will release carcinogenic and pathogenic chemicals; Benzene exceeding the standard is easy to induce cancer and blood system diseases; Some lead compounds dissolve in hot alcohol and acidic beverages, and decompose lead ions. In addition to causing cancer, they can also be passed on to the next generation through the mother, affecting the intellectual development of children
