Are disposable paper cups really safe?

First of all,disposable paper cups 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.

Considerdisposablepaper cups from a health and environmental perspective. So keep your disposable cups to a minimum for your health. If used, it is best to pack cold water to reduce the infiltration of harmful chemicals.Disposable paper cups 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. Because plastic only accounts for 5% of the weight of the paper cup, only a thin layer, the plastic factory also expressed disgust, do not want. Theoretically, recycled paper cupscan be used to make low-grade cartons, such as shoe boxes, express packaging, but because of the high cost of recycling, transportation, processing and so on, enterprises are not willing to do a loss. Basically, the cups end up being incinerated. But at present, there are also a lot of fast food restaurants, coffee shops, milk tea shops, etc., have adopted polylactic acid coated paper cup to replace polyethylene coated paper cup. 

Perhaps there are still many people who do not know what polylactic acid coating is?

It is an environmentally friendly material that can be used in disposable paper cups.Poly (lactic acid) is made of starch raw materials proposed by renewable plant resources (such as corn), which can be biodegradable and has sufficient raw materials and can be recycled. It is an ideal green polymer material, which can realize the recycling of disposable paper cups. However, the cost of poly (lactic acid) is relatively high, one ton of polyethylene is about 12,000 yuan, and one ton of poly (lactic acid) is about 24,000 yuan. The price is twice as high. Due to the high cost, most merchants will not choose polylactic acid (PLA), and the utilization rate is still relatively low. For now, the most environmentally friendly and healthy way to drink water is to prepare your own glass to drink water, clean, sanitary, green and environmentally friendly.
