What is a paper cup material

Poor quality paper cups with recycled polyethylene, in the process can be generated in the process of pyrolysis of change, produce a lot of harmful chemical paper cup
Matter, more easily into the water migration in use. Expert Professor Zhang Qinfa South China Agricultural University Institute of food food packaging materials have pointed out, paper cups in production in order to achieve the water isolation effect, will be in the inner wall is coated with a layer of polyethylene membrane barrier. Polyethylene is the most safe chemical substances in processed foods. But if the choice of materials is not good or processing technology doesn't pass, in polyethylene hot melt or apply to the cups in the process, may be oxidized to carbonyl compounds. Carbonyl compounds less volatile at room temperature, but in the cup into the hot water, it may be volatile out so people can smell the smell. From the analysis of the general theory, long-term intake of such organic compounds, is harmful to human body.
Now in most common use are the paper cup, the outside is a layer of paper, there is a layer of paper coated paper is a kind of inner polyethylene plastic film. The outer layer while the paper, is the inner plastic film but food contact, therefore this kind of glass is defined as the paper cups or plastic cups, controversial. In the detection, both the detection of paper and plastic quality detection.
