[China Packaging Network News] Hot beverage cup lid, baking paper, cake care, etc., these daily necessities easy to ignore the small details of food packaging you have considered it safe? Recently, the International Food Packaging Association released many hidden dangers in the field of food packaging, such as the prohibition of the use of bisphenol A milk bottles, cakes, oil, paper and uniform national standards. What are the hidden dangers of these packaging products? In response, the reporter conducted a survey interview.
Hot drinks cup lids need to look for "QS" logo on a cold winter day to a warm hot drink, warm hands and warm stomach. However, recently on Weibo, some netizens said that “the beverage cup cover is made of Polystyrene (PS Polystyrene) material, which is hot and toxicâ€, and this rumors exploded on the Internet. So, does the beverage cup lid have no poison? What is No. 6 material?
In this regard, Dr. Wei Fengjun, Standing Member of the China Packaging Education Commission and Department of Packaging Engineering of Henan University of Science and Technology, told the reporter: “No. 6 material used for hot beverage cup lids represents polystyrene, and No. 6 material is subject to high temperatures during use. A small amount of styrene monomer will be decomposed, and styrene will be irritating, and when it reaches a certain amount of intake, it may cause cancer and cause some harm to the human body. Generally speaking, the use temperature of polystyrene should not exceed 100 degrees Celsius. ."
Wei Fengjun said that consumers have some misunderstandings about plastic products. Most plastic products will not cause harm to the human body if they are used within the scope of safety standards. And in the hot drinks in winter, the water temperature is usually “does not exceed the range that the oral cavity can bear†and the temperature is not too high. Therefore, in most cases, the hot drinks that consumers receive are below 60 degrees Celsius, and it is generally difficult to reach 90. In degrees Celsius, no carcinogenic substances are produced and consumers do not have to panic.
In addition, Wei Fengjun reminds consumers that when buying hot drinks, the material of the cup cover is white or transparent cup cover is relatively safe, it is generally necessary to look for the blue and white "QS" logo, but it is not that the black cup cover It must be insecure. However, it is inevitable that some cup lids are made from recycled plastic waste. Consumers should pay attention to the identification when purchasing.
The identity of food oil paper is difficult to define. Food oil paper is widely used in daily life, especially for pastry trays and baking papers used in bakery and pastry houses. It is understood that oil paper is a kind of special processing paper, that is, using tougher base paper, coated with tung oil or other dry oil. In 2007, the General Administration of Quality Supervision, Inspection and Quarantine issued the “Implementation Rules for Production Permits for Food Paper Packaging, Containers, and other Productsâ€, which did not define the identity of oiled paper. At present, there are 21 types of food paper packaging, containers, and other products that implement the market access system, and oil paper is not within this range.
Wei Fengjun said that in recent years, some pastry manufacturers or bread houses have used oiled colored paper. For example, on the Mid-Autumn Festival, there were many moon cakes packed with gold and silver moon cakes. In fact, there are safety problems in these trays. Most of the plastics used are secondary plastics. These plastics are often unknown. In addition, gold powder, silver powder and other chemicals are added to the beautiful color of moon cakes, and long-term consumption will cause harm to human health.
In this regard, Wei Fengjun suggested that the relevant departments should issue compulsory uniform standards on edible oil paper as soon as possible. When purchasing cakes, try not to choose glossy oil-colored paper. It is best to choose transparent or white plastic cake holders and bake. Baking paper. At the same time, it should also be noted that the oil paper will precipitate harmful substances at high temperatures and should not be heated in the microwave oven together with the cakes to prevent harmful substances from threatening human health.
The use of bisphenol A vials affected the development of infants as early as September 2011. The relevant national authorities clearly stipulated that the import and sale of bisphenol A vials should be banned. It is understood that bisphenol A is a chemical substance widely used in plastic products or food packaging containers. Adding bisphenol A can make plastic products transparent and durable. Therefore, many plastic products in daily life, such as plastic space cups, Plastic Soymilk, disposable cups, and metal cans contain Bisphenol A.
Wei Fengjun said that related studies have shown that bisphenol A may disturb the metabolic process of the human body and affect the development and immunity of infants. Bisphenol A also has a female hormonal effect that may cause feminization of the baby. When products containing bisphenol A are heated, bisphenol A can be precipitated into foods and beverages, which is harmful to human health. In particular, children are still in the stage of growth and development. BPA containing bisphenol A must be prohibited.
So, what kind of bottle is better for parents to choose? Insiders suggested that the bottle material is best made of metal, followed by glass and again plastic. The most suitable bottle material is glass, one is high temperature resistant, the second is easy to clean, in general, will not break down bisphenol A. Some plastic bottles containing PP, PPSU and PES also have high safety, and consumers can use it with confidence.
