OEM Gel Ice Pack Solutions for Cold Chain: Capabilities & Proven Case Study
OEM Gel Ice Pack Solutions for Cold Chain: Capabilities & Proven Case Study
Changzhou Jisi Cold Chain Technology Co., Ltd is a Chinese factory specializing in the production of gel ice packs, PCM ice packs, cooler boxes, and vacuum insulated panels for refrigerated transport. For procurement professionals at the evaluation-to-execution stage, understanding a supplier's customization depth, production scale, and field-tested application is critical. JISI cold chain supports OEM/ODM development and has a proven six-year deployment in the United States pharmaceutical cold chain.
Problem Definition
Cold chain buyers often need gel ice packs that match specific temperature requirements, dimensional constraints, and branding. Off-the-shelf products may not fit the payload volume or required phase change temperature. The challenge is finding a partner whose customization process is transparent, whose quality control is reliable, and who has already solved similar logistics problems at scale.
Industry Background
The Health & Medicine sector demands stringent thermal performance. Gel ice packs must maintain stable temperatures from -30°C to 23°C for vaccines, biologics, and food. Suppliers must hold food-grade certifications (FDA, SGS, MSDS, CPSIA) to ensure safety when in direct contact with products. The ability to offer multiple form factors — ultra-thin ice bricks, large cooler packs, PCM plates, and flexible gel packs — is essential for multimodal cold chain operations.

Use Case: 1,000,000 PCM Ice Plates for US Pharmaceutical Cold Chain
A logistics and transportation company in the United States deployed 1,000,000 phase change material ice plates from JISI cold chain. The order covered multiple temperature ranges: -30°C, -25°C, -15°C, -10°C, -5°C, 0°C, 2–8°C, 18°C, and 23°C. The solution was used for refrigerated transport of ice cream, food, vaccines, and pharmaceutical drugs. Over a six-year implementation period, the product maintained stable operation, meeting the reliability required for pharmaceutical cold chain logistics.
This case confirms JISI's ability to handle high-volume, multi-temperature OEM projects with consistent quality.
