Identify toxic plastic lunch boxes like this
Although the difference between degradable tableware and non-degradable tableware is not good, it is easy to distinguish whether the disposable plastic tableware is toxic. "It feels limp, and it breaks when you tear it lightly. It chokes when it smells pungent, and it deforms and leaks when heated." At the same time, harmful disposable plastic tableware is added with a large amount of fillers such as talcum powder, so it will sink when it is cut and thrown into water, and a white mark will appear when it is folded.
Experts pointed out that preliminary studies have shown that disposable foamed plastic tableware will produce 16 toxins when the temperature exceeds 65 degrees Celsius. In other words, when you use plastic bags or foamed plastic lunch boxes to fill hot soup, toxins have been inadvertently melted in the food, and the toxic substances such as bisphenols contained in it will precipitate and immerse into the food. In particular, its environmental hormonal effects may cause male feminization and even cause reproductive disorders.
According to doctors, the polystyrene contained in it is strongly irritating, and has an anesthetic effect when the concentration is high, which has serious harm to the central nervous system. If the raw materials contain waste plastics, and the content of heavy metals such as lead and cadmium exceeds normal standards, it can slow down the intellectual development of young children.
A recent study by American researchers found that bisphenol A, a chemical commonly used in food plastic bags, increases the risk of breast cancer in women, especially pregnant women.
Poisonous plastic bags hide hidden hygiene risks
Relevant persons have pointed out that many non-food plastic bags contain toxins, and if they are used as food bags, they will harm the health of users. I believe you can see it in some snack bars. There are many people who eat various kinds of food such as noodles, tofu nao, mala Tang, and most restaurants put a plastic bag in the empty bowl.
According to the restaurant owner, the use of plastic bags to avoid the trouble of washing dishes is acceptable to customers. Some people think that plastic bags are not necessarily good, but they are more reassuring than unwashed bowls.
In some farmer’s markets, many vendors use low-priced wholesale plastic bags. These plastic bags are often scalded at high temperatures and have peculiar smells. They release toxic substances. They are typical "poison bags". The raw materials are recycled waste. Plastics, even pesticides, chemical preparations, medical and chemical packaging, in addition to their own toxins, the colorants and plasticizers used are strong carcinogens, and they are more likely to leak toxins into the food when they come in contact with food, especially oily food. , Causing chronic human poisoning.
Food plastic packaging bags should be non-toxic, and the chemical name of the material is polyethylene or polypropylene. It has low strength, cannot withstand high temperatures above 80°C, and has certain air permeability. We can use the senses and the burning method to identify.
1. The non-toxic polyethylene plastic is milky white and translucent. It has a paraffin waxy feel to the touch, and the texture is soft and bendable. It can float on the water surface when placed in water, and it will soften significantly in boiling water. It is easy to burn in fire, dripping wax when burning, and smell of burning wax. The flame tip is yellow, the bottom is blue, and there is little smoke. It can continue to burn after leaving the fire.
2. The non-toxic polypropylene plastic is milky white and translucent. It is smooth to the touch but not slippery. The texture is firm and tough, and the sound is crisp when shaken. It can float on the water surface when placed in water, but the softening in boiling water is not significant. When it is exposed to fire, it will burn easily and drop waxy substance, expand, and smell of petroleum. The flame tip is yellow, the bottom is blue, and a small amount of black smoke. It can continue to burn after leaving the fire.
3. Toxic polyvinyl chloride plastic is not as transparent as polyethylene, and it feels sticky to the hand. It has a soft and elastic texture. It becomes hard when cold and sinks in water. It is not easy to burn, softens when burned, can be drawn, and has a pungent and spicy taste. The tip of the flame is yellow, and the lower end is green with black smoke. Slowly extinguish the fire after leaving the fire. I hope consumers can pay attention to the distinction and do not misuse toxic plastic packaging.
Due to the simple production process of disposable cups, tablecloths, chopsticks, and dishes, low technical content, and low investment, various types of production companies are rushing to the market. The quality is uneven and the fish is mixed, which makes consumers feel when buying. blindness. Here are three aspects that consumers should pay attention to when purchasing.
When purchasing goods, the network should first pay attention to whether its logo is standardized. The product name, manufacturer name, factory address, trademark, implementation standard, grade, production date or batch number should be indicated on the packaging of the sold product. The disposable chopsticks should also be noted Ming material or tree species. Consumers are particularly reminded to pay attention to whether the implementation standards are marked on the product packaging when purchasing goods. If there are no implementation standards, their products may be produced without standards, and the producer cannot guarantee the continuous and stable production of qualified products.
Since disposable cups, tablecloths, chopsticks, and dishes are all sanitary utensils, they must be sterilized during the process before they can be packaged. Therefore, the packaging should have sufficient airtightness and firmness. When buying, you should choose packaged goods that are clean, free of foreign objects, no peculiar smell, good sealing, no damage, no moisture and other abnormal phenomena.
3. Product quality
Consumers can purchase goods through visual and sensory methods. Disposable paper cups are divided into paper cups and plastic cups. The color of the paper cup body pattern should be uniform, the outline should be clear, the wax layer thickness of the waxed cup is uniform, the coating cup is evenly coated, and there should be no omissions. Wrinkles: The mouth of the plastic cup should be flat and smooth, without waste edges, burrs, and the cup body should be clean and transparent, uniform in thickness, free of impurities, bubbles, and water lines. Press the cup body of the paper cup or plastic cup with your hand, you should choose a disposable cup with a good cup body.
Disposable sanitary chopsticks are divided into two types: bamboo and wood. Choose chopsticks that are free of insect grooves, insect eyes, moth eaten, decay, and odorless. The chopsticks should not be significantly warped, and the surface should be smooth, without obvious burrs and cracks. The length and length of the conjoined chopsticks should be the same, and bamboo chopsticks are not allowed to have bamboo joints, bamboo yellow and other phenomena.
The surface of the disposable dishes should be smooth and uniform, and no folds, holes, and other defects that may affect the use are allowed. Disposable paper cups and dishes should also be noted that the color of the material should be white. If there is a bright white and dazzling feeling, the manufacturer may add fluorescent material to the material to compensate for its color defects, but the fluorescent material is not conducive to Personal health.
Finally, remind consumers that for their own health, please go to regular supermarkets and stores to buy disposable tableware.

Don't be greedy for cheapness and convenience. Buy disposable tableware from street stalls or door-to-door sales. The sanitary conditions, product quality, and consumer rights cannot be guaranteed.
