FAQ
What is the difference between Single PE and Double PE coating for bottom rolls?
● Single PE: Coated on one side only. This is the most economical option and is suitable for standard cold drink cups.
● Double PE: Coated on both sides. This provides better moisture resistance (critical for hot drinks with condensation) and often improves the stiffness and heat-sealing stability. It is the standard for hot coffee cups.
Why is "Stiffness" so important for the bottom roll?
Stiffness is the most critical physical property for the bottom.
Machine Feeding: If the paper is too soft, it will not feed smoothly into the punching machine, causing jams.
Cup Stability: A stiff bottom ensures the cup stands upright on the table without wobbling.
Load Bearing: It prevents the bottom from deforming or "popping out" when the cup is filled with heavy liquid.
What is the core function of the Paper Cup Bottom in a disposable paper cup?
"base support"-it directly determines the cup's leakproofness, structural stability, load-bearing capacity, and usability for both production and end users.
What material types are available for Paper Cup Bottom?
White pe coated paper or kraft pe coated paper.
