The Problem & Goal

In 2018, WITPAX was approached by the rapidly growing cosmetic brand TST, founded by a well-known celebrity couple in China. Attracting significant public attention, TST quickly became known for its signature cosmetic product line: Active Yeast Whitening. However, sudden popularity and extremely high production volume demands exposed critical limitations within their previous packaging solutions—specifically during automated production processes and visual presentation quality.

Existing packaging suppliers of TST struggled to ensure consistent quality and production capacity. Due to inherent structural limitations, the single-card folding boxes used in TST’s Active Yeast Whitening series frequently showed inadequate rigidity and material strength. As a result, finished packaging would become misshapen, compromising both functionality and the brand’s reputation for premium aesthetics.

“Our packaging is the consumer’s first touchpoint—they associate it directly with our product quality and brand identity,” TST’s Packaging Procurement Manager explained. “We urgently needed a robust solution that could maintain premium appearance and performance during high-speed automated packaging.”

The Solution

After thorough on-site visits, discussions, and material assessments with TST’s Shanghai headquarters, WITPAX developed a customized, strategic solution to meet packaging rigidity and visual clarity simultaneously.

The WITPAX team recommended replacing the existing 400gsm white cardboard with a premium double-sided bright silver aluminum foil material. This change significantly increased structure strength and maintained perfect shape integrity throughout the automatic packaging lines.

To address the challenge of double-sided printing with heavy ink coverage, our experts collaborated directly with ink specialists to develop a unique quick-drying UV-curable white ink. Through comprehensive testing and adjustments of offset printing methods, we identified that traditional two-pass white ink printing proved inadequate to produce the vibrant clarity desired by the client. Thus, we modified our printing process to implement an additional print pass, achieving triple-layer printing, ensuring a brighter, sharper, and clear finish in line with TST’s premium branding requirements.

The Results

Upon implementing these carefully customized adjustments, the optimized packaging solution delivered transformative results. TST Cosmetics saw dramatically improved packaging quality, durability, and functionality, as boxes no longer suffered deformation, and the high-definition printing elevated consumer perception of product value and brand trust.

Thrilled with the result, TST’s packaging procurement team shared:
“The upgraded materials and process optimization by WITPAX completely surpassed our expectations. Not only is our packaging stronger and more stable, but visually it now elevates our product significantly—exactly what we required from a premium cosmetics packaging partner.”

This successful packaging revamp established a strong foundation of trust and led TST Cosmetics to expand collaboration with WITPAX for further packaging advancements across various product lines. An additional long-term benefit noted was enhanced efficiency during production, minimizing operational downtime and waste, alongside greater consumer appreciation and higher brand perception.

Conclusion

Today, WITPAX stands as a trusted long-term supplier and collaborative partner for TST Cosmetics, supporting its continued growth by ensuring high-quality, reliable, visually compelling packaging experiences.

“Working together with WITPAX turned our packaging from a functional necessity into an important brand asset,” said TST’s Marketing Director. “They didn’t just solve the immediate challenge—they helped us establish a production approach that will continue to elevate our brand in the long run.”
