Main Features of Double Side PE Coated Paper Cup Bottom Roll
- High Stiffness:
Despite having less plastic, the base paper is engineered to be very rigid, ensuring the cup stands flat and stable.
- Excellent Heat-Sealing Properties:
The PE coating melts uniformly under heat, creating a strong bond between the bottom disc and the cup body. This ensures the cup can hold boiling water without leaking.
- Consistent Thickness:
Precision-calibrated thickness ensures that the automatic punching machine cuts the bottom circles accurately every time, reducing production waste.
- Moisture Resistance:
Resists softening caused by condensation (sweat) on the outside of cold drink cups.

FAQ
How should I load the roll into the machine?
This depends on your specific cup-forming machine model.
Critical: You must ensure the PE side is oriented to form the seal. If loaded incorrectly, the cup will leak because paper cannot heat-seal to paper.
Always consult your machine manual or test with a small sample first.
Is the uncoated side printable?
Yes. The uncoated paper side has excellent printability.
However, since the bottom of the cup is usually hidden, printing on the bottom roll is rare. It is more common to print on the cup body (fan).
How do I know which side is the PE side?
You can identify the PE side in three ways:
Visual: The PE side looks smoother and has a slight gloss or shine; the paper side looks matte and fibrous.
Scratch Test: Rub your fingernail across the surface. The PE side is smooth and resistant; the paper side will show scratches or fluff.
Water Test: Drop a small amount of water. The PE side will bead up (waterproof); the paper side will absorb the water immediately.
