Meta Description (160 characters)
TOP1 China plastic cup factory since 2005: Food-grade PET/PP/RPET cups with leak-proof tech. Custom sizes/shapes for coffee/bubble tea. FDA certified + eco options. Free samples & global shipping.
Introduction (Hook):
“Why do 73% of beverage spills originate from cup seams? Discover how precision engineering solves leakage at molecular level.”
1. Material Science Simplified
- PET Cups: Crystal clarity & recyclability (FDA Grade A)
- PP Cups: Microwave-safe durability (withstands 120°C)
- RPET Cups: 30% recycled content, carbon-neutral certified
*Lab Insight: “Our stress-test videos show RPET cups surviving 5kg vertical crush forces”*
2. Leak-Proof Technology Explained
- Seamless Sidewalls: Laser-welded joints (0.1mm precision)
- Capillary Seal Rim: 15° patented angle creates liquid-lock
- Test Results: Zero leaks at 3m drop height (carbonated drinks)
3. Smart Stacking Engineering
- Tapered Design: 0.08mm wall variance enables 1-hand extraction
- Anti-Vacuum Grooves: Prevents cup “sucking” during separation
- Space Savings: Nested cups reduce shipping volume by 55%
4. Customization Capabilities
Option Specs Printing CMYK/Pantone, FDA-compliant inks Shapes Square, cone, hexagon (+ anti-roll) Sizes 4oz-32oz (±1% capacity accuracy) Eco-Upgrades PLA/Sugarcane compostable versions
