Advantages of Double PE Coated Paper Cup Bottom
High-Temperature Resistance：
The PE formulation is designed to withstand temperatures up to 100°C (212°F) without melting or becoming tacky. This prevents the bottom seal from failing when hot coffee is poured in.
Superior Stiffness：
Coffee cups are often tall (12oz, 16oz, 20oz). The bottom roll must be rigid enough to support the hydrostatic pressure of the liquid without bulging out.
Excellent Sealing Strength：
Ensures a permanent bond between the bottom and the body. The seal remains intact even if the cup is squeezed or transported.
Moisture Barrier：
Prevents "sweating" (condensation) from weakening the paper fiber structure, which could cause the cup to collapse when held.

FAQ
Why is the PE coating on coffee cup bottom rolls different from regular cold drink cups?
Coffee cup bottom rolls use a High-Temperature Resistant PE formulation.
Regular PE can soften or melt at temperatures above 70°C, which would cause the bottom seal to fail when hot coffee is poured in.
Coffee Grade PE is designed to withstand temperatures up to 100°C (212°F) without losing its structural integrity or seal strength.
Do I need Double PE coating for coffee cup bottoms?
Yes, Double PE is highly recommended.
Inner Side: Prevents the hot liquid from soaking through the paper.
Outer Side: Prevents condensation ("sweating") from weakening the paper structure. If the paper absorbs moisture from the outside, it loses stiffness, and the cup may collapse when the customer picks it up.
Why do coffee cups sometimes leak only after 5-10 minutes?
This is often caused by "PE Migration" or "Softening."
If the PE coating is too thin or of poor quality, the hot liquid can cause the plastic to creep away from the seal area over time. Using a high-quality, sufficient thickness (20gsm+) of heat-resistant PE prevents this delayed leakage.
