30mm Water Bottle Caps

ODM/OEM Customization Services

We provide comprehensive ODM and OEM cap customization services for our clients, tailoring the cap's neck structure, liner solution, opening torque, color, and marking processes according to the brand's preform specifications, filling equipment parameters (ambient or hot filling), and appearance design requirements. This helps clients build brand-differentiated bottled water/beverage packaging solutions while ensuring sealing performance and hygiene safety.

Customizable options include:
1. Neck structure matching: Confirm the compatible 30mm neck finish parameters based on the customer's existing preform molds or blow-molding equipment, avoiding the extra cost of redeveloping preform molds.
2. Liner options: Foamed liner, heat-resistant sealing liner, or linerless direct sealing structure available, confirmed based on the filling medium (ambient water/hot-filled juice/carbonated beverage) and storage period.
3. Opening torque: The target opening and closing torque range can be confirmed based on the customer's preform specifications and filling line equipment parameters, balancing sealing performance with consumer opening experience.
4. Appearance and marking: Customizable Pantone colors supported; logo/printing options include embossing, in-mold, pad printing, or surface printing, confirmed based on MOQ and mold design.
5. Packing quantity: Bulk or carton-packed, with quantity per carton confirmed based on the customer's storage and production line loading method.
Cooperation Process:
1. Select a model: Let us know the neck size you need (30mm) along with the bottle shape, volume specifications, and filling method (ambient/hot filling). Send us your specific requirements, and we will respond with a quotation within 24 hours.
2. Custom development: Once the proposal is confirmed, we will complete sample verification within 72 hours, testing the structural fit between the cap and neck, sealing performance, and brand logo compatibility.
3. Production and delivery: Strict quality control is implemented throughout production. Upon order completion, a full inspection is carried out, and the products are shipped to the designated address within the agreed timeframe.

Stable and Reliable Supply Chain Assurance

As a professional cap manufacturer, we have established a one-stop supply chain system covering raw material procurement, production processing, and logistics distribution, ensuring precise coordination at every stage of cap production and providing clients with stable, timely, and flexible supply assurance.
To ensure product traceability and transparency, we monitor and record key production information — including raw material suppliers, manufacturing processes, and quality inspections — allowing clients to quickly trace any issue back to its source in the event of an abnormality.
Our overall supply chain system has been certified by an independent third-party organization, providing objective verification of quality compliance and supply chain reliability, giving bottled water and beverage brands greater confidence in partnership. In the event of production disruptions or urgent order needs, we are committed to prioritizing scheduling to help minimize the risks associated with supply chain interruptions.
