Core Characteristics:
Smooth interior wall finishes to prevent milk fat buildup and bacterial growth.

Vented spouts or weighted straw systems to reduce air ingestion and prevent colic during milk consumption.

FAQ

Q: How do you prevent milk fat buildup inside the anti-colic valves?

A: Our valves utilize smooth-surface LSR with a polished inner runner mold finish (Ra < 0.2 μm), preventing protein adhesion and allowing easy rinsing under hot water.

Q: Are your sippy cups compliant with European EN 14350 standards?

A: Yes. Third-party test reports from SGS/TÜV covering chemical migration, mechanical strength, and bite resistance are available for active buyers.

Q: Can we mix different colors within the standard MOQ?

A: Yes. For standard PP and silicone models, the MOQ of 3,000 units can be split across up to 3 different Pantone-matched colors (minimum 1,000 units per color).

Q: What is the lifespan of the silicone straw and valve components?

A: Under normal daily use and standard steam sterilization cycles (121°C), replacement is recommended every 3 to 6 months. Replacement parts can be bundled into your bulk orders.

Q: How do you handle drop-test performance for stainless steel models?

A: Double-wall stainless steel cups undergo drop testing from 1.2 meters onto concrete surfaces at room temperature and -10°C to verify weld integrity and vacuum retention.

Q: What is your standard payment term for new OEM accounts?

A: 30% T/T deposit upon contract signing, with the remaining 70% balance payable against copy of Bill of Lading or following third-party pre-shipment inspection (PSI).
