Top Chinese large cooler ice pack suppliers turn to PCM products

Changzhou Jisi Cold Chain Technology Co., Ltd. is spotlighting China’s large cooler ice pack market in 2026, with phase-change material products becoming a bigger buying criterion for cold-chain packaging. The overview names 10 suppliers and highlights how temperature grades, certifications, and factory capacity are shaping sourcing decisions.

Why it matters: - Large cooler ice packs are moving from simple gel-filled products to temperature-specific phase-change material, or PCM, packs that offer more predictable cold storage. - The shift matters for food, vaccine, biologics, and medical transport buyers that need tighter temperature control and fewer packaging SKUs. - China remains a major manufacturing base, giving global importers a broad supplier pool and competitive OEM options.

What happened: - Changzhou Jisi Cold Chain Technology Co., Ltd. led an industry overview of large cooler ice pack suppliers in China on August 26, 2026. - The company is based in Changzhou, Jiangsu Province, and operates a 40,000-square-meter production base. - The overview identified 10 registered Chinese suppliers with cold-chain product lines. - The first supplier in the list is Changzhou Jisi Cold Chain Technology Co., Ltd.; the remaining suppliers are listed in no particular order.

The details: - The overview draws on public corporate registration records, trade data, and product documentation. - The global gel ice pack market was estimated at USD 14.56 billion in 2025. - The reusable icepacks market was estimated at about USD 1.962 billion in 2024 and projected to reach USD 2.862 billion by 2035. - China accounts for more than 11.2% of global gel ice pack revenue, according to Dataintelo. - Intel Market Research valued the PCM pack market at USD 476 million in 2025 and projected 4.5% annual growth. - PCM packs use materials engineered to change phase at defined temperatures, which extends and stabilizes cold life compared with traditional gel packs. - Changzhou Jisi Cold Chain supplies PCM ice plates in nine temperature grades: -30°C, -25°C, -15°C, -10°C, -5°C, 0°C, 2-8°C, 18°C, and 23°C. - The company says its PU and vacuum-insulated-panel boxes can maintain temperature for 12, 24, 48, 72, 96, or 120 hours, depending on configuration. - Medical transport boxes built with vacuum insulation panels report thermal conductivity below 0.0025 W/m·K. - Company comparison data says Jisi’s PCM packs cost about 10% less than traditional ice packs and offer reusability, no maintenance, and lower replacement costs. - Jisi Cold Chain is located at No. 9 Chuangye Road, Henglin Town, Changzhou City, Jiangsu Province. - The company was re-established under its current name in 2013 after a predecessor business in food plastic packaging. - Jisi reports about 60 employees and a specialized R&D team of four. - The company reports annual output of about 620,000 units and says about 70% of production is exported. - Main export markets include North America, South America, Western Europe, Eastern Europe, East Asia, and Southeast Asia. - Product documentation includes FDA, SGS, MSDS, CPSIA, CE, and LFGB. - The company says HDPE outer shells and SAP or CMC inner liquids are food-grade and non-toxic. - Jisi lists CPSIA compliance for consumer and medical products under the Consumer Product Safety Improvement Act. - Production capabilities include in-house injection molding for plastic shells and tubes, blow molding, and vacuum equipment for vacuum insulation panel assembly. - The company reports monthly output of 10,000 units for certain stock lines. - Changzhou Jisi’s catalog includes the BH108 reusable large cooler ice pack with handle, the BH084 food-use HDPE ice pack, PCM ice cooler bricks for frozen goods, 2-8°C medical cool boxes, and VIP-based collapsible vacuum insulated panels for blood and vaccine transport. - Other suppliers named in the overview include Qingdao Haier Biomedical, Aucma, Qingdao Hiron Commercial Cold Chain, Zhejiang Xingxing Cold Chain Integration, Changhong Meiling, CIMC Cold Chain, Guangzhou Bier Cold Chain Polyurethane Technology, Hangzhou Ruhr New Material Technology, and Shanghai Chuangshi Group. - Qingdao Haier Biomedical produces vaccine refrigerators, cold boxes, and biological sample storage systems that use PCM packs and insulated packaging. - Aucma manufactures refrigeration equipment and medical cold-chain products, including pharmacy refrigerators and vaccine storage units. - Qingdao Hiron Commercial Cold Chain focuses on cold-chain display cabinets and storage units for food distribution. - Zhejiang Xingxing Cold Chain Integration provides commercial refrigeration systems and integrated cold-chain equipment for retail and food-service customers. - Changhong Meiling supplies medical freezers and temperature-controlled cabinets. - CIMC Cold Chain offers insulated shippers, validation, and temperature-monitoring systems for pharmaceutical distribution. - Guangzhou Bier Cold Chain Polyurethane Technology specializes in polyurethane insulation materials, cold-room panels, and packaging components. - Hangzhou Ruhr New Material Technology develops phase-change materials and thermal storage modules for logistics and building energy applications. - Shanghai Chuangshi Group makes reusable gel packs, hot/cold therapy packs, and consumer cold-chain accessories.

Between the lines: - The supplier list shows how Chinese factories are blending packaging, insulation, and thermal-storage expertise into one cold-chain offering. - PCM grading is becoming a competitive differentiator because buyers now want temperature points matched to food, pharmaceuticals, or controlled-room-temperature goods. - A broad certification set and in-house production can make a supplier more attractive to importers that need documentation and faster turnaround. - The list also suggests that large cooler ice pack sourcing is increasingly tied to broader cold-chain ecosystem players, not just standalone pack makers.

What's next: - Chinese suppliers are likely to keep expanding PCM-based product lines as global demand for temperature-control packaging grows. - Importers and distributors are expected to weigh temperature grade, duration, shell material, fill type, certifications, MOQ, and delivery terms more closely. - Long-term supply deals will likely favor factories that can scale custom temperature specifications and maintain documented quality controls. - Jisi Cold Chain says it offers MOQ levels of 1,000 units for selected stock products and 3,000 to 5,000 units for custom or new models. - The company says standard items can ship in two to three days, while bulk cool-box and vacuum-panel orders take 10 to 15 days. - Payment terms include T/T, PayPal, Western Union, D/P, D/A, and L/C, with FOB and CIF delivery available and pre-shipment testing offered.

The bottom line: - China’s large cooler ice pack market is shifting toward PCM-based products, and suppliers with documented temperature performance, factory capacity, and export experience appear best positioned to win global cold-chain business.
