Case Study: D35 Center Dispensing Cap for the South Korea Market

Case Study: D35 Center Dispensing Cap for the South Korea Market

Market Background

South Korea’s skincare industry is known for its high standards in packaging precision, user experience, and product consistency. In this market, consumers expect packaging to deliver not only functional reliability but also a refined and repeatable usage experience.

For products such as facial cleansers, lotions, and lightweight creams, inconsistent dispensing—such as uneven flow, over-dispensing, or residue buildup—can negatively impact both usability and brand perception. As a result, brands increasingly prioritize controlled dispensing systems and tactile-friendly packaging designs.

Customer Profile and Application Scenario

The customer is a South Korea-based skincare brand focusing on daily-use facial care products, including cleansers and lotion-based formulations. The primary packaging format is D35 cosmetic tubes, widely used for mid-size and travel-friendly SKUs.

Key requirements included:

• Precise and controlled dispensing for medium-viscosity formulations

• Enhanced tactile experience aligned with Korean market preferences

• Compatibility with standard D35 tube packaging lines

• Stable supply with a short lead time

The annual demand reached approximately 1 million units, with a required lead time of around 1 month to support fast product cycles.

Our Solution

To meet these requirements, a D35 soft touch center dispensing cap with dual-material construction (PP + TPE) was implemented, combining structural precision with enhanced user interaction:

• Center dispensing structure: A centralized flow path that improves dispensing consistency and reduces off-center output

• 4.0 mm orifice size: Designed to regulate flow for cleansers and lotion-type formulations

• PP + TPE dual-material design:

  • PP inner layer ensures structural rigidity and dimensional stability

  • TPE outer layer provides a soft-touch surface for improved grip and tactile comfort

• D35 compatibility: Enables seamless integration with standard tube formats and existing filling lines

This solution provided a balance between controlled dispensing performance and refined user experience, meeting both functional and aesthetic expectations.

Technical Performance Summary

The effectiveness of the solution is supported by several key technical parameters:

• The 4.0 mm dispensing orifice ensures controlled and repeatable product output, reducing the risk of over-dispensing

• The center flow path design minimizes uneven output and helps maintain a clean dispensing area

• The dual-material (PP + TPE) structure separates mechanical stability from tactile performance

• The D35 size compatibility supports efficient integration into standardized tube packaging systems

These features enable stable performance across both production and daily consumer use.

Customer Feedback

According to customer feedback, the implemented cap solution delivered:

• More consistent dispensing behavior across repeated use

• Improved handling due to the soft-touch surface, especially in skincare routines

• Reduced product waste through better flow control

• Reliable supply aligned with the required one-month lead time

The customer reported a high level of satisfaction with both product performance and supply efficiency.

Conclusion

This case demonstrates how a D35 center dispensing cap can effectively meet the expectations of the South Korean skincare market. By combining a 4.0 mm controlled orifice, center dispensing structure, and PP + TPE dual-material design, the solution provides a practical and scalable approach to improving dispensing consistency and user experience.

For brands operating in fast-paced and quality-focused markets, this type of packaging solution offers a reliable way to enhance both functionality and perceived product value.
