The coating weight refers to the weight of the Polyethylene or Polylactic Acid film laminated onto the paper substrate, measured in grams per square meter (GSM).

• Barrier Properties: Higher coating weight provides better liquid barrier (leak and seepage resistance). Hot drink cups require higher PE coating weight (22-28 gsm) for leakage prevention and strong seam seal.
• Heat Resistance: For PE, higher coating weight improves heat resistance.
• Softness & Stiffness: Coating adds softness to cup feel, though excessive thickness might slightly reduce wall rigidity.
• Cost & Environmental Impact: Heavier coating uses more plastic, increasing cost and environmental impact with more non-biodegradable/compostable material.
