A variety of materials used in plastic bottles packaging

Plastic products have involved all aspects of our lives, but do you know how many kinds of plastic? What kind of plastic products in what kind of situation will produce what kind of harm?

CPPCC members and Liu Lifang, secretary of the Party Working Committee of Guilin Street in Zhongshan District of Dalian City, proposed that the emergence of plastic products has provided convenience for people's lives, but also caused great harm to the environment.

7 plastic markings indicate their use

When people use plastic bottles under different conditions, they do not have enough knowledge of the human body. Most of the plastic bottles we use daily are made of chemical products such as high-density polyethylene, polyvinyl chloride, low-density polyethylene, polypropylene, and polystyrene. Manufacturers use different labels for these items, namely 1, 2, 3, 4, 5, 6, and 7. Each label has a triangle with an arrow on the outer ring.

No. 1 PEI is a common mineral water bottle, heat-resistant to 70 °C easily deformed. The carcinogen DEHP may be released after the first bottle is used for 10 months.

HDPE No. 2 is a common medicine bottle, cleaning product and bath product. It cannot be used for water storage in a storage box, and it cannot be recycled.

No. 3 PRC common raincoats, construction materials, plastic films, plastic boxes, etc. Do not recycle or package foods.

No. 4 PE common plastic wrap, plastic film, can release toxic substances at high temperatures, it can lead to breast cancer after the food into the human body, newborn birth defects and other diseases, but can not put plastic wrap with food into the microwave oven.

No. 5 PP common milk bottles, yogurt bottles, juice bottles, microwave lunch boxes, etc., melting point up to 167 °C, can be reused after careful cleaning, some microwave Lunch Box body made of PP No. 5, but the lid is Made of No. 1 PE. Because PE cannot withstand high temperatures, it cannot be placed in the microwave oven with the box body.

No. 6 PS common snack box, instant noodle box, can not be heated in the microwave, but can not be loaded with acid, such as orange juice, alkaline substances, can not be dressed hot food, so as not to release carcinogenic substances.

On the 7th PC, there are common kettles, space cups, and baby bottles. These plastic products cannot be exposed to sunlight, cannot be heated, and cannot be poured into boiling water. When heated, they can release carcinogenic substances.

No. 1 plastic products are often used and used by us. Some people do not know this knowledge and use mineral water bottles to hold edible oils and other seasonings. This repeated use can lead to the incidence of cancer. The most toxic are plastic containers No. 3, No. 6, and No. 7, which are more harmful to human bodies.

Ultrathin plastic bags are still popular in farmers' markets

Liu Lifang pointed out that there are various types of ultra-thin plastic bags that have no signs. Since June 1, 2008, the state has restricted supermarkets, as well as the morning and night markets from prohibiting the use of ultra-thin plastic bags, and it has been performing well for more than two months. . However, since September and October of that year, many of the city's morning and night markets have used 100% of ultra-thin plastic bags.

In addition, the use of QS plastic bags in cooked foods is not optimistic. From January 1, 2008, according to the stipulations of the State Administration of Quality Supervision, the Chinese government enforces the compulsory access system for food plastics. However, in addition to the large-scale supermarkets in Dalian, almost all raw and cooked foods are packed in plastic bags for food use. In the farmers’ market, as well as in the streets and around the food stalls around the school, cooked food such as steamed buns, steamed buns, and freshly cooked meat products can be found everywhere. There are no QS logos and strange smells. The phenomenon of common white plastic bags produced by small family workshops.

These white plastic bags without the QS logo are filled with recycled plastics. The recycled plastics are mostly synthesized from recycled plastic waste and even medical infusion needles. The main component of PVC is a toxic chemical raw material. When it comes to acidic and oily substances, especially when cooked foods with higher temperatures are encountered, the harmful substances are easily absorbed by the food and enter the eater's body. The long-term use of plastic bags made of recycled plastics to package foods can easily lead to chronic food poisoning and central nervous system diseases.

It is suggested to strengthen management from the source

Liu Lifang proposes to start from the source and strengthen the supervision of plastic bag manufacturers so that ultrathin plastic bags can be completely withdrawn from the production process. At the same time, the awareness of environmental protection of market management personnel has been strengthened, supervision and management have been strengthened, spot checks have been carried out from time to time, and hawkers who do not listen to discourage are firmly banned.

Intensified efforts were made to implement compulsory enforcement of the entry system for food plastics, including food handlers and plastic bag producers. In particular, enforcement of mandatory food packaging using QS logos for cooked foods was strengthened to ensure The quality and safety of whole cooked food packaging in Dalian.

Adhere to the long-term propaganda of public opinion, call on the public to properly use a variety of plastic products, and consciously use eco-bags to fundamentally resist the use of ultra-thin plastic bags.
