At present, domestic disposable cups can be divided into three types according to their use: cold drink cups, hot drink cups and ice cream cups; according to the use of paper cups, the coatings are also divided into three types, one is a wax coating cup, and the other is coated with polyethylene. Membrane cups and straight wall double cups.
The waxing cup is coated with a layer of wax used to separate the water.

The coated cup of polyethylene is a film covered with polyethylene on the wall of the cup.

The wall of the straight-walled double-layer cup has two layers of paper, and there is air between the paper and the paper, and the heat insulation is very good.

The most common use on the market today is the disposable paper cup made of polyethylene coating material, which is safer. The production process of polyethylene coated paper cups is: base paper - laminating - printing - die cutting - forming - packaging. This paper cup is usually a layer of coated paper on the inner wall and a layer of paper on the outside. Some manufacturers will also spray a film on the outer wall of the paper cup after printing.
