The food grade PP material baby water cup clamp ring is a key component for sealing and fixing the structure of the water cup. Its material meets food contact safety standards, combines durability and safety, and is suitable for daily drinking scenarios for infants and young children. The following describes from three aspects: material characteristics, functional design, and applicable standards:
1、 Core materials and safety properties
Food grade PP material: Made of PP (polypropylene) raw material that meets the standards of "Plastic Products for Food Contact" (GB4806.7-2024), with a high temperature resistance of up to 120 ℃, free of bisphenol A and plasticizers, ensuring that no harmful substances are released when in contact with infant drinks.
Physical stability: The material has moderate hardness, is resistant to falling and deformation, and is not easily aged or cracked after long-term use. It is also resistant to acid and alkali corrosion, and can safely come into contact with common baby drinks such as milk and fruit juice.
2、 Functional Design and Practical Value
Sealing and Leak Prevention
The clamp ring tightly adheres to the interface between the cup lid and the cup body, and forms a dual leak proof structure with a silicone sealing ring, effectively preventing liquid overflow when the cup is poured. It is suitable for various types of baby water cups such as straw cups and school drinking cups.
Easy to disassemble and clean
Adopting a split design, it can be disassembled and cleaned separately to avoid residual dirt in blind spots such as sealing rings. It supports high-temperature water boiling disinfection (recommended water temperature ≤ 80 ℃ to prevent accelerated material aging).
Lightweight and adaptable
Lightweight and compact in structure, it does not increase the overall burden of the water cup, and is compatible with the standardized interface of most brands of baby water cups, such as the 300-400ml capacity products of brands such as Ping Mo Shi and Bei Qin.
3、 Applicable scenarios and usage recommendations
Target audience: Designed specifically for infants and young children over 7 months old, it is compatible with transitional water cups such as school drinking cups and straw cups, helping babies practice drinking independently.
Maintenance cycle: It is recommended to replace it every 1-2 years. If yellowing, scratches, or decreased elasticity occur, it should be replaced in a timely manner to ensure sealing performance.
Paired with PP material straws, food grade silicone nozzles, and other accessories, it forms a complete infant and toddler drinking water safety system, enhancing the user experience.
