Model NO. XHY | Coating Side: Single and Double | Sample: Free Available | Feature: Waterproof

• Enhanced Rigidity: The curled structure functions similarly to architectural "arch" or "I-beam" principles, effectively dispersing vertical and lateral pressure on the cup body.
• Wide Contact Surface: Well-designed bottom roll creates a circular contact surface slightly larger than the cup diameter, providing excellent stability and preventing tipping.
• Pressure and Impact Resistance: Sturdy bottom roll effectively resists deformation when paper cups are stacked or compressed, protecting cup structure and preventing "bursting" or severe deformation from hydraulic pressure.

• Precision Mold: Bottom roll shape, width, and compactness are determined by high-precision molds, with mold quality directly determining bottom roll quality.
• Narrow Process Window: Curling force, heating temperature, and time require precise control to prevent weak adhesion, leakage, or damage to paper fibers and PE film.
• 100% Flawless Requirement: Any defects in bottom roll (uneven edges, gaps, burns) result in waste, demanding extremely high stability and accuracy from production equipment.
