Ar an gcéad dul síos,cupáin páipéir indiúscartha aren't just made of paper. To make the paper cup insoluble, a thin layer of polyethylene plastic is placed on the inside of the paper cup,which prevents the cup from getting soggy while also keeping the contents somewhat warm. Many people think that a layer of wax on the paper cup, in fact, it is not a layer of polyethylene, one of the main components of the paper cup, so the key to the problem falls on this layer of polyethylene (PE) material. PE material applicable temperature is generally below 100℃, if you use adisposable paper cups to drink water, in the case of high temperature plastic inside the low molecular substances and additives may dissolve in water, in addition, there are individual bad manufacturers in order to reduce the cost and use waste paper processing paper cup, and add talc, fluorescent whitening agent and other substances, harm health.
Cupáin páipéir indiúscarthaIndiúscartha are difficult to recycle. Polyethylene plastic is coated on the inner wall of the paper cup. This layer of plastic is inseparable from the paper cup, making it difficult for the paper factory to recycle paper.
