A romantic cream-toned thermal bag for Cha Li Yi Shi, featuring colorful scattered florals and a vintage label-style brand mark that embodies the brand’s “Chinese Romanticism” philosophy.
Cha Li Yi Shi (茶理宜世) is a Guangzhou-based fresh-tea brand that has distinguished itself in China's competitive beverage market through a singular aesthetic vision: "Chinese Romanticism." While most tea chains chase modern minimalism or cartoon cuteness, Cha Li Yi Shi cultivates a nostalgic, romantic atmosphere inspired by Republican-era Shanghai, vintage European tea salons, and classical Chinese poetry. The brand's stores are designed as immersive romantic spaces, and every touchpoint — from cup design to staff uniforms — reinforces this carefully constructed world.
Every cup of tea we serve is a love letter. The bag that carries it should feel like an envelope for that letter.
The thermal bag was developed as part of a seasonal spring collection that celebrated the brand's romantic philosophy through floral motifs and vintage design language. The bag needed to maintain beverage temperature while functioning as a collectible object that customers would preserve and reuse.
The bag was engineered for cold-beverage delivery while preserving the delicate, vintage-inspired aesthetic. The multi-color floral pattern required precise registration, and the cream base demanded color consistency to maintain the warm, paper-like quality.

Three design decisions differentiate this romantic tea bag from standard beverage packaging. Each leverages nostalgia and emotional warmth to create lasting customer attachment.
01 Vintage Label as Time Travel The apothecary-style oval frame transports recipients to an imagined past of hand-labeled botanical products. This nostalgia trigger creates emotional warmth that modern, minimalist packaging cannot replicate. The vintage aesthetic doesn't just decorate the bag — it tells a story about tradition and craftsmanship. 02 Scattered Florals for Joy The random, colorful floral distribution creates a sense of spontaneous natural beauty rather than rigid pattern design. This organic scattering feels more like a garden in bloom than a manufactured print — conveying the romantic, slightly wild spirit that the brand cultivates. 03 Cream Base for Versatility The warm ivory tone functions as a neutral that coordinates with any outfit, any season, and any setting. Customers report carrying the bag to work, dates, and weekend outings — a versatility that maximizes brand exposure across diverse life contexts.
