Science recycles plastic bottles to avoid a health crisis
Science recycles plastic bottles to avoid a health crisis
The heat of the day, drinking water, beverage, etc. Some of the better-quality, well-packaged plastic bottles have been used again, and this seemingly environmentally friendly behavior poses a health hazard.
Food experts point out that people think they value food safety, but often ignore the importance of food plastic packaging. How to identify these plastic beverage bottles, water bottles, oil bottles and other materials and quality? The key lies in the bottom of the bottle, which is a returnable triangular sign made up of three arrows, as well as any number between 1 and 7 in the triangle. However, the reporter recently found out in the market research: whether it is the salesperson, the consumer to this small triangle understanding basic blank; Some well-known food brands have not even labeled the logo, and even some brands have been treated separately from different flavors of the brand.
survey
Supermarket promoters ask three unknown
It is not hard to find out that there are three arrows at the bottom of individual beverage bottles that can be recycled and recycled. The three arrows are formed into a triangle with Numbers 1-7, each representing a chemical material that can be used to understand how plastic bottles are reused. "What does the icon and number stand on the bottom of the plastic bottle?" In recent days, when reporters visited many supermarkets, such as baijia, China resources, and other supermarkets to consult relevant sales staff, the sales staff in the supermarket shook their heads. In bofeng lotus three yuan shop reporters took a bottle of alcohol unified ice jasmine tea ask promoters, the promoters at the logo has a half a minute, then said to the reporter: what is not clear ICONS, but this is a new taste, recommend journalists can give it a try. The reporter interviewed 10 consumers at the scene, and eight of them said they didn't know what they were. Only two consumers recognized that it was a recyclable sign, but the exact meaning of the Numbers was unclear.
Big corporate logos are also messy
On the one hand, it is the weakness of the terminal consumer consciousness, on the other hand, the attention degree of the businessman is uneven. Reporters visited bofeng lotus found three yuan shop: mark the most specification is drinking water industry, including diet treasure, nongfu spring, Watson, kang teacher, unity, yili, and many other brands of drinking water are marked "1" in the bottom of a bottle. The label of edible oil industry is also standardized, including gold longfish, lu hua, dao mark, eagle mark and other mainstream edible oil brands. Half of the tea drinks are not labeled, such as master kong's tea drinks and so on. As for carbonated beverages, Coca-Cola and Pepsi, Sprite, beautiful lotus, striking series of brands, such as plastic bottle did not see the triangle number icon, no logo at the bottom of the plastic bottles, means that consumers cannot know the material of plastic bottles, such as repeated or improper use is likely to affect health.
And the reporter found, have the beverage brand the product that the same series of different taste, whether annotation can be treated differently. Such as the reporter sees in October 14, 2009, the production of lemon flavour of gatorade bottle has marked with the words "1" recycle logo, but the 2010 production of blueberry, ice orange two flavors of products is not recycled logo. There is also a part of the condiment brand, such as the 800 ml of the sea, the weipole is unmarked, but its silver standard is marked.
At the same time, the reporter also found that some drinks, especially the color of the drink, the bottom of the label is very fuzzy, if you don't look closely, you can't see the bottom of the bottle.
Lack of standards leads to market turmoil
It is understood that the plastic recycling symbol of Europe, America, Japan and other countries all plastic production enterprises are classified according to ISO11469 international standards of plastic products, substandard plastic products are not allowed to enter the market. In 1996, China introduced the recycling of plastic packaging products (GB/T16288 -- 1966), and some serious brand enterprises have started to mark the recycling symbols in order to facilitate the recycling of plastic products. However, because the plastic labelling is not mandatory, many manufacturers do not label beverage bottles.
According to common international practice and the established practice in the industry, as a production enterprise is a must in materials of plastic product, if is a sign of PET bucket on PC, this practice is illegal.
Plastic signs is aimed to facilitate recycling, if consumers read labels carefully, can also pass the id know the use of plastic products are made of what material, in what circumstances should use, but in fact, the propaganda about this logo both government departments and enterprise investment is insufficient, this makes the understanding of the consumers is almost blank.
Hidden danger citizens blindly reuse
Reporter through visit found that at present the most widely applied to plastic packaging for the food industry are labeled 1 plastic bottles, drinking water, beverage, condiment, edible oil and other plastic packaging is to give priority to. For different types of food, these plastic bottles are hard and different, such as plastic bottles for drinking water, which are generally soft, while some functional drinks are more rigid. Also used is the PET material, but the bottle body soft and hard won't make many consumers very easy to "recruit".
The reporter interviewed 20 people at random. Eight of them told reporters that they had recycled plastic bottles.
The main purpose is to fill the water and fill the oil. In Newport west trust-mart stores to buy drinks food aunt zhang told reporters that at ordinary times out movement with some boiled water beverage bottles, bottle are hard drink boiled water is no problem, recycling more environmentally friendly, but some body soft deformation when pour boiled water, don't use.
But experts generally agree that qualified beverage bottles and mineral water bottles are all required to be made of food-grade plastic, or PET bottles. These food-grade PET bottles are not able to withstand high temperatures and need to be used at low temperatures. It is generally safe to use under 70 degrees Celsius. In addition, these plastic bottles are disposable. The state stipulates that enterprises cannot recycle and repeat filling. Experts have also suggested that plastic bottles are more difficult to clean, and repeated use will breed lots of bacteria.
In other words, the public has been thinking that recycling more environmentally friendly ideas may actually be a danger to the health of the body. Therefore, it is necessary for every consumer to see the number of the bottom triangle of plastic bottle, and use it carefully when mastering its material performance.
It is recommended to use PP material for food packaging boxes
It is understood that food delivery and packaging materials are also being implemented in the restaurant industry. For example, many restaurants offer diners grade PP plastic boxes for packaging, but is typically charge 5 Angle - 1 yuan/a, many consumers on hearing this charge, would rather choose cheap foam lunch boxes, is not willing to spend the money. People with dual-use plastic products told reporters that the food box made of PP is about three times more expensive than the cost of a foam lunch box, but it can be heated in a microwave oven. But the prevailing market phenomenon is not that businesses are not willing to use it, but consumers are not willing to use it. The relevant person in charge of a large restaurant chain company Mr Tsang said in an interview with reporters, at present, the company delivery rules, if use foam plastic packaging, every time delivery charge 1 yuan, but if use PP material packing, each item is 5 extra Angle, the vast majority of consumers, are choosing the way of only 1 yuan extra.
