Double sided PE coated paper cup: a paper cup produced with double-sided PE coated paper. Its appearance is characterized by PE film on the inside and outside of the cup.
2, Different uses.
The hot cup uses a single-sided PE coated paper cup. There is a layer of PE coated paper in the cup, which can be slightly insulated. The most important thing is to prevent water seepage, so that the hot drink will not leak out.
The cold cup is made of double-sided PE coated paper cup. The layer outside the cold cup will have condensed water vapor, which will deform and soften the cup. Adding a layer of film can increase the hardness and shaping.
3, The quality is slightly different.
The single-sided PE coated paper cup is produced by using the single-sided PE coated paper cup, and the double-sided PE coated paper cup is produced by using the double-sided PE coated paper cup. Compared with the single-sided PE coated paper cup, the double-sided PE coated paper cup has better quality, longer service life, higher straightness and higher relative cost.
