Main Features of Double Side PE Coated Paper Cup Bottom Roll
- High Stiffness:
The paper is designed to be rigid and unyielding. This prevents the bottom from bending when the cup is placed on a table, even when filled with heavy liquids.
- 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
What is the difference between "Body Stock" and "Bottom Roll"?
Body Stock: This forms the side wall of the cup. It requires good printing surface and flexibility to curl easily. The GSM is usually lower (190gsm - 250gsm).
Bottom Roll: This forms the base of the cup. It does not need to curl, but it requires high stiffness and thickness to support the weight of the liquid. The GSM is usually higher (250gsm - 400gsm).
Can logos, brand names or patterns be customized on the Paper Cup Bottom?
Normall the logo, brand names or patterns will be printed on the cup body ( cup fan).
What equipment is the Paper Cup Bottom suitable for? Can it be used on standard paper cup forming machines?
We can produce the cup bottom according to your forming machine.
What are the common forming problems of Paper Cup Bottom and their solutions?
Bottom Leakage (60%)
Core Causes
Hot-press temperature is too low or uneven (PE coating not fully melted, no seamless fusion).
Hot-press pressure is too low (insufficient contact between cup bottom and cup body flange, fusion gaps exist).
PE coating on cup bottom/cup fan is uneven or pinhole-prone (missing PE in bonding area).
Incomplete folding of cup body bottom flange (uneven flange width, partial no contact with cup bottom).
Solutions
Calibrate mold temperature to 115–120℃ (suitable for kraft paper) with a thermal imager; replace damaged heating tubes.
Increase pressure to 10–13 bar (for 300g mainstream cup bottom); check and calibrate the flatness of pressure plate.
Strict raw material inspection: reject products with PE pinholes/unevenness; ensure coating weight 18–22g/㎡ per side.
Adjust the folding mold to ensure a uniform 3–5mm flange width (full contact with cup bottom).
