There are two kinds of Paper cup (container) in the world. One is hot beverage use and the other is cold
beverage or ice cream use. And paper cup for hot beverage uses single P.E. coated paper
as a material, while the other one does double P.E coated paper.
If single P.E coated paper is used for cold beverage, it will cause some problem.
When cold beverage or ice cream is contained in sigle P.E coated paper made cup, something
like dew will appear soon and make the paper wet out side. So that is why double P.E coated
paper is used for cold beverage normally.
