Paper Cup Fan Buying Guide: From Basis Weight to PE Coating—How to Choose the Right Material
If you run a Paper Cup Manufacturing factory, you're probably familiar with the following scenarios:
Frequent machine downtime: The fan-shaped sheets have many burrs on the curved edges, causing paper jams, misalignment, and poor heat sealing after loading.
Leaking finished cups: Hot coffee leaks through the side seams within five minutes, leading to numerous complaints.
Blurry printing and fading: The logo is dark, and the edges are blurred, resulting in customer rejection.
Large batch quality fluctuations: Different batches of the same specification have inconsistent stiffness.
These problems all point to the same root cause: choosing the wrong paper Cup Fan.
The paper cup fan is a core semi-finished product: PE-coated paper is printed and die-cut into fan-shaped sheets, which are then rolled, heat-sealed, and joined to the cup bottom by the forming machine to create a complete paper cup. Quality is determined by: forming yield, cup stiffness, leak-proof performance, and printing effect.
Key Technical Specifications:
- Base Paper Gram Weight (150–320 gsm): Lower gram weight results in thinner and softer paper (small-capacity drink cups), while higher gram weight results in thicker and stiffer paper (large-capacity drink/heavy oil containers). When purchasing, ask about the gram weight of the base paper and PE coating, not just the total gram weight.
- PE Coating: Single-sided PE is used for hot/cold drink cups, while double-sided PE is used for ice cream/heavy oil containers. Optimal PE gram weight: 13–20 gsm. Too thin and it won't leak properly; too thick and it will be difficult to heat seal.
- Stiffness: Determines whether the paper cup can stand upright; depends on gram weight, pulp quality (virgin wood pulp is better than recycled pulp), and the uniformity of the PE coating.
- Printing: Flexographic printing, 1–7 colors, Pantone color matching, food-grade water-based inks.
- Die-cutting Precision: Rotary die-cutting offers higher precision, smoother edges, and compatibility with mainstream forming machines.
