FAQ
Why do cup bottom roll need to be so stiff?
Stiffness is the most critical property of the bottom.
Stability: It prevents the cup from wobbling or tipping over.
Load Bearing: It stops the bottom from bulging out when the cup is filled with a heavy liquid (like water or iced coffee).
Machine Feeding: Stiff paper feeds more accurately into the punching machine without bending.
What is the standard GSM for a cup bottom roll?
The GSM (thickness) depends on the size of the cup:
Small Cups (4oz - 7oz): 230gsm - 270gsm
Medium Cups (8oz - 12oz): 270gsm - 320gsm
Large Cups (16oz - 22oz): 320gsm - 360gsm
Buckets: 350gsm - 450gsm+
Why does the bottom of my cup leak?
Leaks at the bottom are usually caused by a failure in the heat seal between the bottom disc and the body wall. Common causes include:
Insufficient PE Coating: The bottom disc doesn't have enough plastic to melt and bond properly.
Dust/Debris: Dirt on the sealing surface prevents the PE from sticking.
Machine Settings: The temperature or pressure on the sealing head is too low.
Wrong Material: Using cold-drink grade PE for hot coffee (the heat weakens the seal).
