PP Cup
Product Overview
Polypropylene (PP) cups designed for beverage service, daily food packaging, and general retail use. Produced through automated thermoforming and injection molding lines, these products maintain structural integrity across various beverage temperatures. Compatible with standard plastic lids and heat-sealing films, ensuring reliable performance for daily liquid containment.
Material & Construction
Resin Grade:
Homopolymer and random copolymer polypropylene (Virgin prime grade, compliant with major food-contact regulations including FDA 21 CFR 177.1520 and EU No. 10/2011).
Thermal Window:
Withstands continuous operational temperatures from -20°C to 120°C; microwave-safe and blast-chiller compatible.
Wall Architecture:
Uniform wall thickness distribution achieved through multi-zone temperature-controlled mold design, preventing thin-spot failures under vertical load.
Rim Geometry:
Rolled or smooth-cut structural rim designed to maintain dimensional stability and form a positive seal with plastic lids and heat-sealing films.
Key Features
Stress Resistance:
Formulated to resist environmental stress cracking when exposed to dairy fats, oils, and mild food ingredients.
Clarity Options:
Available in ultra-clear optical grade for visual product display, translucent natural, or custom masterbatch colors.
Stacking Efficiency:
Engineered with anti-jamming internal draft angles and precise separation ribs to ensure reliable single-cup dispensing in automated or manual units.
Purity Standards:
Free from plasticizer migration, verified through migration testing under simulation fluids.

Applications
Beverage Service:
Bubble tea shops, coffee houses, juice bars, and quick-service dining.
Food Retail:
Yogurt, dessert, and cold-salad portion packaging.
Daily Use:
Household gatherings, events, and everyday beverage consumption.
Production Line: Fully automated thermoforming lines integrated with inline vision inspection systems for defect detection (pinholes, foreign particles, rim distortion).
Cleanroom Environment: Injection and thermoforming executed under controlled cleanroom standards to meet hygiene requirements for food-contact packaging.
Testing Protocols:
Top-load compression testing (measures vertical stacking strength up to 50 kg).
Drop impact testing (1.5 meter drop test filled with liquid at 4°C and 90°C).
Seal integrity testing via dye penetration and burst pressure testing.
Traceability: Laser-etched mold cavity numbers and batch timestamps on every master carton for end-to-end production tracking.
