Catering food packaging selection and use precautions
[Chinese Packaging Network News]
Disposable paper napkins used in restaurants have raised concerns among consumers. According to multiple reports, many of these napkins are made from recycled waste paper, which may contain impurities. To mask the imperfections and make the paper look whiter, harmful substances such as fluorescent whitening agents and industrial talcum powder are often added. These chemicals can be potentially carcinogenic. If you notice that the napkins are dark, rough, or brittle with visible paper fragments, it's best to avoid using them for wiping your mouth. Also, colored or patterned napkins should be avoided as they may contain toxic dyes.
Disinfecting wipes have also become a topic of concern. Many products contain excessive bacteria, fluorescent whitening agents, aluminum foil bags, and industrial-grade fragrances. When purchasing wet wipes, always check the manufacturer’s name and expiration date on the packaging. It is especially important to limit their use for infants and young children, as their skin is more sensitive.
Mooncake plastic trays have been found to contain high levels of phthalates—up to 800 times the allowed limit. To reduce health risks, it is advisable to choose mooncakes that come in simple, minimal packaging rather than those in plastic containers.
Stainless steel cutlery, while durable, can pose a risk if it contains excessive amounts of heavy metals like iron, chromium, and nickel. Prolonged contact with acidic or salty foods may cause rusting, and some low-quality products may leach harmful substances into food.
PVC cling film is another product to be cautious about. It contains plasticizers that are harmful to human health. In China, it is classified as a restricted material and should not be used for wrapping fatty, hot, or cooked foods. Although many manufacturers still use it, consumers should look for the “PE†label instead of the yellow-colored PVC film, which is unsafe.
Colorful straws are often made from low-quality materials and are considered "three-no" products (no production license, no quality certificate, no trademark). The brighter the color, the higher the risk of harmful substances being released when in contact with hot drinks.
Disposable foam lunch boxes are typically made from polystyrene and other harmful chemicals. They should only be used for cold food and not for hot or greasy meals. Always look for the QS logo when purchasing, and try to minimize their use to protect your health.
Melamine tableware, often mistaken for porcelain, is difficult to distinguish by appearance alone. When buying, choose reputable stores and opt for plain-colored items. Avoid using them in the microwave, as high heat can release harmful chemicals.
By being aware of these potential dangers, consumers can make safer choices and protect themselves from harmful materials in everyday products.
