Disposable paper cups are made of coated paper and have high strength and water resistance. Depending on the field of use, their water and oil resistance properties need to meet certain standards. What standards do manufacturers need to meet during processing? Let's take a look below.
1. Firmness
The product should have good firmness, which can be firmly adhered to the paper to improve processing performance.
2. Resistance to penetration
Because it is used in the production of paper cups, due to the exposed paper edges of the cup body and cup body, the product needs to have corresponding resistance to moisture penetration.
3. Stiffness
Mainly reflected in the overall stiffness, low elongation in the vertical and horizontal directions, and relatively tight paper, which is prone to fractures or other situations in subsequent processing, requiring the product to have a certain degree of stiffness.
