Whether the plastic cup is safe or not can be tested with alcohol

1. The cling film is less exposed to grease

PE and PVC are common foreign names in cling film and storage bags. PE, which is polyethylene, is almost the safest of all types of materials used in plastic films. It is preferred to be labeled "PE" at the time of purchase and is preferably colorless. Qualified PVC (polyvinyl chloride) is also safe, but when it is applied to plastic films, a large number of "plasticizers" are required, the most common being phthalate plasticizers. A large number of studies have shown that phthalates have an estrogen-like effect, which interferes with the human reproductive system and affects the development of children's sexual organs. They are prone to overflow after encountering oil. Since China's laws do not explicitly prohibit the use of PVC plastic wrap, consumers should also pay attention to the use of cling film: try to avoid plastic wrap, plastic bags contact the surface of the food with grease, especially do not touch the hot grease, carefully wrapped with plastic wrap Chicken, duck, fish, etc. are heated in a microwave oven.

2. Plastic cups can be used for alcohol color test

Colorful plastic cups are a favorite of many people. Plastic container products are preferred PP materials, preferably colorless. There is an easy way to judge the failure of a colored plastic cup: take a clean cotton (or white cotton), rub it with alcohol or cooking oil, and rub it back and forth on the surface of the product. If the cotton ball is stained with the color of the colored product, It indicates that the colorant has migrated out and the product quality is unqualified. If the cotton is continuously wiped more than 100 times, the cotton buds are still not dyed, indicating that the possibility of colorant migration is small and can be used with confidence. In addition, please pay attention to whether there is any odor when purchasing, and the bad odor indicates residual solvent or other impurities.

3. Crystal glass is not safer

Ceramic and glass products are also commonly used food containers. Some consumers prefer “high-end” crystal glass, which is actually a misunderstanding. Crystal glass contains lead oxide, which has a higher lead migration than ordinary glass products. Before using the newly purchased glass products, consumers can soak them in vinegar and water for 24 hours, then pour the vinegar water and then soak them in new vinegar water. Repeat this three times. According to the technical center test, the heavy metal migration of such glass products usually drops greatly, and can be used with confidence.
