Plain Paperboard Cups
Made from untreated white paperboard, these cups are not suitable for liquids, especially hot drinks. They easily warp, leak, and pose hygiene risks. Best reserved for dry foods.
• Wax-Coated Paper Cups
These cups are lined with a thin layer of wax, offering short-term waterproofing for cold beverages only. When used for hot drinks, the wax may melt and release chemical residues. Some low-cost waxes even contain harmful industrial paraffin.
• PE-Coated Paper Cups (Polyethylene)
These are the most widely used cups for hot beverages. The PE layer offers excellent temperature resistance, leak prevention, and durability. However, the plastic lining can complicate recycling unless collected through specialized waste streams.
• PLA-Coated Paper Cups (Bioplastic)
Lined with polylactic acid (PLA) derived from renewable resources like corn starch, these cups are compostable in industrial facilities and widely adopted by eco-friendly cafes. However, they require specific composting conditions to degrade and may still face limitations in some recycling systems.
• Aluminum Foil-Lined Paper Cups
These offer superior heat insulation and are often used in aviation or high-end foodservice. While they prevent leaks effectively and retain heat longer, they are not recyclable through standard paper waste streams and can be expensive.
