The London-based startup Delta H Innovations has introduced "Cool Can," a self-cooling aluminum can technology. By pressing a button on the base, an internal water-salt reaction cools the beverage to 6-7°C within 10 minutes and maintains this temperature for up to 45 minutes. The can features a double-layered aluminum wall design: the lower layer stores water, while the middle layer contains proprietary salts. When activated, the reaction absorbs heat to chill the drink, with a snowflake indicator turning blue to signal cooling completion.

Journalist tests confirmed the can’s surface felt cold and condensed, validating its cooling effect. Though capacity is 70% of a standard 500ml can, founder James Vyse emphasizes advantages like eliminating refrigeration costs and full recyclability. The company is now in talks with brands like Coca-Cola and Red Bull for pilot launches.

Future Impact of Self-Cooling Cans on Aluminum Beverage Packaging

1. Structural Design and Manufacturing Advancements

· ‌Double-Layered Aluminum Wall Integration
Self-cooling cans require precision in sealing and layering technology, pushing traditional single-layer can production lines to evolve. This innovation demands higher structural stability and material compatibility.

· ‌Balancing Lightweighting and Functionality
While standard cans have reduced aluminum use (e.g., 330ml cans now weigh 13g vs. 80g historically), self-cooling cans’ double-layer design may increase material needs. Innovations like Toyo Seikan’s CBR technology (13% weight reduction) could optimize this trade-off.

2. Sustainability and Recycling System Adaptation

· ‌Recyclability Verification
Aluminum’s high recycling rate (over 80% in North America) remains a strength, but self-cooling layers (water/salts) must align with existing recycling processes to avoid contaminating recycled aluminum.

· ‌Low-Carbon Material Innovations
Combining aluminum foil encapsulation for cooling stability with lightweight designs (saving 200,000 tons of aluminum annually per 1g reduction per can) could further cut carbon footprints.

3. Market Expansion and Consumption Scenarios

· ‌Differentiation Strategy
Self-cooling functionality positions aluminum cans as "smart containers," enabling premium branding (e.g., Red Bull and Coca-Cola collaborations) and differentiation from standard cans.

· ‌Non-Refrigeration Scenarios
Ideal for outdoor, sports, or emergency use, self-cooling cans leverage aluminum’s portability (dominant in 80% of North American RTD beverages) to compete with PET bottles in non-cold-chain markets.

4. Industry Collaboration Challenges

· ‌Cost vs. Scalability
Double-layer structures may raise per-can costs by 20-30%, requiring scaled production (e.g., Toyo Seikan’s 190ml lightweight can output) to balance functionality and affordability.

· ‌Safety and Standardization
Unified safety standards are needed for cooling agents (e.g., antimony catalyst risks) to prevent chemical migration. Lessons from PET bottle reuse hazards can guide risk mitigation.



Self-cooling technology is transforming aluminum cans from passive containers to ‌active functional carriers‌. However, large-scale adoption hinges on cross-industry collaboration to resolve structural innovation, recycling compatibility, and cost control. This breakthrough could drive the metal packaging industry’s next growth phase.

For all Aluminum Can Manufacturers‌: Staying ahead requires continuous innovation aligned with evolving consumer demands. Embracing advancements like self-cooling technology ensures long-term relevance in the dynamic metal packaging sector.
