Disposable plastic cups are mainly divided into three types by raw materials
1. PET cup
PET, No. 1 plastic, polyethylene terephthalate, commonly used in mineral water bottles, various beverage bottles and cold drink cups. It is easy to deform at 70 ℃, and substances harmful to human body melt out. Do not bask in the sun, and do not contain alcohol, oil and other substances.
2. PS cup
PS, No. 6 plastic, polystyrene, can withstand a temperature of about 60-70 degrees. It is generally used as a cold drink. Hot drinks will release toxins and have a brittle texture.
3. PP cup
PP, No. 5 plastic, polypropylene. Compared with PET and PS, PP cup is the most popular plastic container material, which can withstand the temperature of 130 ° C and is the only plastic container material that can be put into the microwave oven.
When selecting plastic disposable water cups, identify the bottom logo. No. 5 PP cup can be used for both cold and hot drinks, and No. 1 PET and No. 6 PS can only be used for cold drinks, remember.
Whether it is a disposable plastic cup or a paper cup, it is better not to reuse it. Cold and hot drinks must be separated. Some illegal businesses use recycled waste paper and recycled plastics for the benefit of others. It is difficult to count all the impurities, but also contains various heavy metals or other harmful substances. Therefore, it is better to choose products from regular manufacturers. What ordinary consumers do not understand is that between disposable plastic cups and paper cups, plastic materials are superior to paper. It can be considered from two aspects: 1. The manufacturing process of disposable plastic cups is relatively simple, and the hygiene is easy to control. Paper cups are relatively complex, with many production links, and sanitation is not easy to control. 2. Qualified disposable plastic cup, non-toxic and pollution-free. Even qualified paper cups are easy to separate foreign matters. In addition, the materials used for paper cups are from trees, which consume forest resources excessively and have a great impact on the environment.
