Factory Manufacturer Beverage Paper Cup Material Paper Cup Bottom Roll leakproof Waterproof

Features

1,Mechanical properties: providing stability and compressive strength
Enhanced rigidity: The curled structure is similar to the principle of "arch" or "I-beam" in architecture, which can effectively disperse the vertical and lateral pressure of the cup body.

Wide contact surface: A well-designed bottom roll will form a circular contact surface slightly larger than the diameter of the cup body, providing excellent stability and preventing the paper cup from tipping over easily.

Pressure and impact resistance: When paper cups are stacked or subjected to external compression, the sturdy bottom roll can effectively resist deformation and protect the cup structure. When picking up a paper cup filled with water, the bottom will not "burst" or deform severely due to hydraulic pressure.

2,Process characteristics: High precision and consistency requirements
Precision mold: The shape, width, and compactness of the bottom roll are determined by high-precision molds. The quality of the mold directly determines the quality of the bottom roll.

Narrow process window: The curling force, heating temperature, and time all need to be precisely controlled. Insufficient force or temperature can lead to weak adhesion and leakage; Excessive force or temperature may crush paper fibers or cause excessive melting of PE film, affecting appearance and strength.

100% flawless requirement: Any paper cup with defects on the bottom roll (such as uneven edges, gaps, burns, etc.) means that the paper cup is a waste. Therefore, the stability and accuracy requirements for production equipment are extremely high.Mechanical properties: providing stability and compressive strength
