What is Flagging Tape?

The plastic product recycling label was established by the Society of the Plastics Industry (now renamed Plastics Industry Association) in 1988. This set of identification puts the plastic material identification code on the container or packaging, from No. 1 to No. 7, so that people do not need to worry about learning the similarities and differences of various plastic materials, they can simply join the ranks of recycling. Each plastic container has a small identification card-a triangle symbol, which is usually on the bottom of the plastic container. There are 1 to 7 numbers in the triangle. Each number represents a kind of plastic container. They are made of different materials and have different taboos.

In foreign countries, the classification and identification of plastic products is very important. All plastic production companies in Europe, the United States, Japan and other countries classify plastic products according to the ISO11469 international standard. Plastic products that do not meet the standards are not allowed to enter the market at all. And in China it's simply not possible at this time.

The national standard refers to the international standard of ISO11469? 2000 "Marks and Symbols of Plastic Products". The plastic materials used include plastic materials such as general plastics, engineering plastics, functional plastics, degradable plastics, antibacterial plastics, and recycled materials. Mark and mark. The new national standard also adds more than 200 types of plastic materials and signs, adds requirements for the marking and marking of plastics for food packaging and medical plastics, and adds functional and supplementary instructions to the signs, and requires that they be marked. The proportion of recycled material in the raw material.

It is particularly worth mentioning that the logo pattern required by the national standard is vivid and more humane. For example, a pattern of two arrows in opposite directions indicates that the product can be used repeatedly. As long as people with similar literacy levels have similar patterns, they can judge the 'origin' and 'home' of the plastic products in their hands from these specific and visual signs. This simple and clear label solves the difficulty for people to identify plastic materials. It can not only promote waste plastics classification and collection, but also save manpower, material resources and funds required for sorting and classification, and reduce the amount of domestic waste. 2. Eliminating 'white pollution' has far-reaching significance.

Plastic Recycling Mark Expert Reminds

It is often seen that people like to use used beverage bottles and mineral water for tea, and some consumers have also cheered for it, thinking that this is "environmental protection" and "saving". However, a few days ago, Dong Jinshi, deputy chairman of the Plastics Recycling Professional Committee of the China Plastics Association reminded in an interview with reporters that plastic bottles should not be used repeatedly. Otherwise, high-temperature water and acidic solutions will easily dissolve harmful substances inside, which is harmful to human health.

Hidden dangers of plastic recycling signs

In daily life, repeated use of beverage bottles and mineral water bottles is common. Many consumers often like to keep their used beverage bottles and mineral water bottles, and fill them with tea or drinking water when they go out next time. They call this "environmental protection" and "saving." Dong Jinshi said that qualified beverage bottles and mineral water bottles are required to be made of food-grade plastics, that is, PET bottles. These food-grade PET bottles are not resistant to high temperatures and need to be used at low temperatures. Generally, it is safe to use below 70 degrees Celsius. In addition, these plastic bottles are disposable, and the state stipulates that enterprises cannot recycle and refill.

Jiang Zhuoqin, professor of the Department of Nutrition, School of Public Health, Sun Yat-sen University, also pointed out that plastic bottles are added with plasticizers during the manufacturing process, and the chemical composition has a toxic effect on the human body. It is easy to dissolve the harmful substances inside and bring them into the human body. He suggested that using glass, stainless steel and other bottles for food is relatively safe.

Plastic bottle bottom numbers have nothing to do with safety

It is rumored that some plastic bottles are safe and can be used repeatedly, and it is not safe to use a plastic bottle repeatedly. It can be identified by the logo on the bottom of the bottle. Some netizens on the Internet claim that many beverage bottles and mineral water bottles have a triangle sign with an arrow at the bottom. There is a number in the triangle. If the number is "05" or above, it can be reused, and the larger the number, the safer it is. "The bottom of a general mineral water bottle is marked 01; the bottom of a plastic heat-resistant cup of general tea is marked 05; the bottom of a creamer bottle is marked 02; the bottom of a yogurt bottle is marked 02 ..." Some agree, while others doubt its authenticity.

The number marked on the triangle on the bottom of the plastic bottle has nothing to do with whether the bottle is "safe". The triangle symbol is a plastic recycling symbol. There are numbers from 1 to 7 in the triangle. Each number represents a different material. If the product is made of several different materials, the main and basic materials of the product are marked. Recycling marks on plastic products are not mandatory. Some regular big brand companies have recently started to mark recycling marks in order to facilitate the recycling of plastic products. Experts believe that although this mark is mainly for the convenience of recycling, consumers can also use this mark to know what material the plastic product is made of and under what circumstances it should be used.
