Moon cake packaging box, toxic plastic cake tray and oil paper without health protection

As the footsteps of the Mid-Autumn Festival are getting closer, mooncakes have become the protagonists of major shopping malls. At this time of the year, the luxury and quality of moon cakes will become the focus of public opinion. However, all along, the focus on mooncake packaging, mainly in its flashy, but it is easy to ignore the health and safety issues of "intimate contact" packaging.

“The cartons used to package moon cakes are basically poisonous!” Recently, Mr. Shao, who is engaged in moon cake making in Foshan, reported to the Nanfang Daily reporter that the moon cake box on the market contains toluene. If consumers eat this poisonous The moon cakes in the box will be chronically poisoned and may even cause cancer.

Food packaging professionals remind consumers that when buying moon cakes, not only the quality of the moon cake itself, but also the environmental protection of the moon cake packaging should be observed to avoid damage to the body.

Broke the news: the moon cake box has a pungent smell

“Now the mooncake packaging is getting more and more beautiful, but the security issue is very prominent.” Mr. Shao said that a few days ago, in order to purchase the mooncake packaging box, he went to the wholesale market to buy some back, but approached the wholesale stall. You can smell a pungent smell.

According to Mr. Shao, the reason why the moon cake box exudes such a pungent taste is the glue used to bond the box. “These glues contain toxic toluene chemicals. I saw that some of the employees in the packaging factory are rotten. Consumers who eat the moon cakes in this box will definitely be affected.”

"Some boxes are covered one layer after another, and each layer must be glued with glue, which is more serious." Mr. Shao said that for the human body, this poison is a long-term, causing chronic poisoning. The migrant workers working inside, inhaling this toxic gas every day, is even more harmful. I hope that through your appeal, we can purify this industry and protect the health of migrant workers. ”

According to the reporter, the path of toluene invading the human body mainly involves inhalation, ingestion, and absorption through the skin. Health hazards include irritation to the skin and mucous membranes, and anesthesia to the central nervous system. If a high concentration is inhaled in a short period of time, obvious irritation of the eyes and upper respiratory tract, conjunctival and pharyngeal congestion, dizziness, headache, nausea, vomiting, chest tightness, weakness of the limbs, gait, and confusion may occur. Severe cases may have convulsions, convulsions, and coma. Long-term exposure can cause chronic toxic symptoms such as neurasthenia syndrome, hepatomegaly, dry skin, chapped, and dermatitis.

“The chemical substances contained in the adhesive are very toxic to the human body.” Food packaging professionals pointed out that many “three no” packaging boxes are mostly produced in small workshops, and the quality is worrying. There are also some small processing plants that use fluorescent whitening agents to improve the whiteness of the paper during the production process. This substance is carcinogenic. It is understood that the manufacturer's name, address and telephone number should be marked on the regular food packaging box.

Status: plastic moon cake support, oil paper without sanitation

After visiting several mooncake packaging wholesale markets in Guangzhou, Ms. Chen, a citizen of Guangzhou, also complained to reporters about the chaos. “I originally prepared to make moon cakes and give them to my relatives and friends, but the wrapping paper on the market was too unsanitary, and I finally had to give up this plan.”

According to Ms. Chen, she first planned to use moon paper to pack moon cakes, but when she went to the store, she found that the oil paper was simply wrapped in a plastic bag. When the customer bought one, the boss took one. She did not buy because of the heart. The whole market gave her the impression that it was “dirty, chaotic, and poor”, which made her really dare not imagine that what people eat is closely related to it.

According to a survey by reporters, in recent years, some manufacturers have used gold and silver moon cakes to hold moon cakes in order to make moon cakes appear high. These brightly colored mooncake holders are made from recycled powder and gold powder and silver powder. The sources of these recycled plastics are complex, and some even come from medical waste, pesticide bottles, etc. The use of recycled plastics and mooncake holders made of gold and silver powder is prone to contain a large amount of toxic substances and heavy metals.

Interpretation: Recycled plastics dissolve mercury and cadmium in moon cake oil

“Polyvinyl chloride, a main component of recycled plastics, is a toxic chemical raw material that cannot be used in food packaging.” Dong Jinshi, secretary general of the International Food Packaging Association, said that when PVC encounters acidic and oily substances, toxic components will Freed out, the moon cake itself has a relatively large oil content, and it is easy to absorb the toxic substances in the recycled plastic.

Among them, mercury and cadmium are two highly toxic heavy metals. Mercury will sink into the liver after being eaten by the human body, causing great damage to the brain, nerves and vision. Cadmium can replace some of the calcium in the bone, causing the bones to loosen and soften and sputum. In severe cases, it causes natural fractures and even teratogenicity. Cadmium can also cause high blood pressure, cause cardiovascular and cerebrovascular diseases, damage liver and kidney, and can cause kidney failure.

Reminder: "Colored" is more suspicious

According to Dong Jinshi, in general, mooncake holders with color are unsafe, while white and transparent are not made of recycled plastic, and the safety factor is relatively high. He suggested that consumers can check the mooncakes against the light and the sun. If the mooncakes have obvious impurities, black spots and uneven color are likely to be recycled plastics. It is also dangerous to smell odor.

Dong Jinshi reminds consumers that when buying moon cakes, don't be confused by bright packaging, because some packaged moon cakes are more likely to contain toxic substances, and boxed moon cakes are usually kept in cold storage for a long time, which may not be fresh enough. .

In addition to using moon cakes, many moon cakes are now covered with a layer of plastic packaging. According to food packaging professionals, toxic and harmful chemical pollutants left inside plastic packaging materials may migrate and dissolve under certain conditions, resulting in food contamination. . If you smell the plastic, it is definitely a toxic and harmful product. Wooden food packaging containers, the surface must be treated, or painted, and the colored pigments may also contain heavy metal salts. Today's particularly popular density fiberboard mooncakes and tea packaging boxes are worrying because they contain large amounts of free formaldehyde and other harmful volatiles.

Look at the digital identification box

A triangular number symbol appears on the bottom of most plastic boxes. The entire pattern may also include arrows or other numbers that are used to distinguish the product material category. If you can't find the relevant content on the outer packaging, you must think twice before buying. When buying a food box, a few numbers deserve our special attention:

Number 3: This number represents PVC. This material is hard and often used in the manufacture of food boxes, water pipes and building materials, and is widely used in everyday life. In general, food boxes made from this material are only suitable for storing dry, low-moisture foods such as rice and pasta. PVC is not resistant to high temperature, so be sure to transfer the food to a food container suitable for microwave use before heating the food.

Number 6: This is the sign of polystyrene. This material is sometimes foamy and is used primarily for making disposable lunch boxes, cups and cutlery. Among all types of food packaging materials, polystyrene has the lowest melting point, so although it can be used to hold warm foods, do not use this food box to heat directly.

Numeral 7: This number represents a material other than PVC and polystyrene or a composite material of various plastic materials. If the raw material of the food box is polycarbonate (containing bisphenol A, considered to be an endocrine disruptor), this number will appear on the product. These food box materials are various, and their heat resistance and maintenance methods are also different. Please read the product description carefully before use, and strictly follow the manufacturer's instructions.
