Main Features of Double Side PE Coated Paper Cup Bottom Roll
- High Whiteness & Purity: Made from fully bleached pulp, it looks clean and professional, complying with strict food hygiene standards.
- Superior Stiffness: Engineered to be rigid and thick, providing a solid foundation that prevents the cup from tipping or buckling.
- Excellent Heat Sealability: The uniform PE coating ensures a strong, leak-proof bond between the bottom disc and the cup wall during the high-speed forming process.
- Dimensional Stability: Resists warping or curling, ensuring the automatic machine can punch the bottom circles accurately.
- Cost-Effective: Since the bottom is hidden, using plain white paper reduces costs compared to printed paper without sacrificing quality.
- Moisture Resistance: Resists softening caused by condensation (sweat) on the outside of cold drink cups.

FAQ
Is the paper food safe?
Yes. Our bottom rolls are made from Food Grade Virgin Wood Pulp and Food Grade PE Resin. They are compliant with international standards such as FDA (USA), EU 10/2011, and LFGB (Germany).
What is the lead time for delivery?
● Stock Sizes: 3-5 working days.
● Custom Sizes/Grammages: 7-15 working days, depending on the order quantity.
How should I store the bottom rolls?
To maintain quality, the rolls should be stored in a cool, dry warehouse.
Temperature: 20°C - 25°C.
Humidity: 50% - 60% (Avoid high humidity as paper absorbs moisture and loses stiffness).
Handling: Store horizontally on pallets; do not place heavy objects on top of the rolls.
What are the common forming problems of Paper Cup Bottom and their solutions?
Cup Bottom Tilting / Unstable Placement
Core Causes
Hot-press temperature is too high (PE coating is over-melted and carbonized, reducing adhesion with paper).
Inconsistent PE coating grade of cup bottom and cup fan (different melting points, uneven fusion).
The bonding area has dust/oil (contamination reduces PE fusion effect).
Cooling time is too short (PE layer is not fully solidified, easy to peel when stressed).
Solutions
Lower the hot-press temperature to 110–115℃; avoid over-melting of PE coating for kraft paper.
Unify PE coating grade (LLDPE for hot drink cups, LDPE for cold drink cups) for cup bottom and cup fan.
Install dust removal devices on the production line; clean the mold and pressure plate regularly; prohibit oily hands from touching the bonding area.
Extend cooling time to 2–3s; ensure PE layer is fully solidified before the cup is transferred to the next process.
