What Are Eco Friendly Dry Ice Packs and Why Should You Switch?
Eco friendly dry ice packs are cooling systems designed to maintain ultra low temperatures while minimizing environmental impact. Unlike traditional gel packs or disposable ice, these packs harness dióxido de carbono sólido (hielo seco) o materiales de cambio de fase (PCM) to keep goods frozen or chilled without leaving behind watery messes. Dry ice sublimates directly from solid to gas at about –109.3 °F (–78.5 °C), providing stable, ultra cold conditions necessary for sensitive shipments. Because it sublimates, there is no liquid meltwater that could damage packaging or products. Even better, dry ice is often produced from recycled CO₂ captured from industrial processes, turning waste gas into a useful refrigerant.
Why they are better than traditional options
Reduced Plastic Waste: Traditional gel packs require plastic shells that often end up in landfills. Dry ice eliminates that need and relies on reusable, contenedores aislados.
Lower Carbon Footprint: Dry ice is a by product of industries like ammonia and ethanol production, meaning its use repurposes existing CO₂ rather than generating new emissions.
Minimal Water Consumption: Producing ice or gel packs uses considerable water. Dry ice is created without water, conserving resources.
Recyclable and Biodegradable: Because dry ice sublimates completely, there is no solid waste to dispose of—making it a natural, biodegradable refrigerant.
Long term Use: Many eco friendly packs are designed for reuse, allowing businesses to reduce costs and waste over time.
These advantages make eco friendly dry ice packs a smart choice for companies facing pressure to reduce their environmental footprint while still delivering safe, high quality products.
Key Components and How They Work
Eco friendly dry ice packs typically consist of three major components:

Environmental Impact and Sustainability Benefits
Why sustainability matters
Cold chain logistics relies on vast quantities of packaging materials and refrigerants, many of which end up as waste. En 2018 the U.S. generated 80,000 tons of expanded polystyrene (EPS) foam packaging, yet menos que 1 % was recycled. Traditional gel packs contain petroleum based gels and plastic liners that linger in landfills. Consumer and regulatory pressure is mounting: 43 % of consumers consider packaging sustainability when making purchasing decisions, and many countries and U.S. states are restricting EPS use.
Eco friendly dry ice packs address these issues through several environmental advantages:
Repurposed CO₂: Dry ice is produced from industrial by product CO₂, reducing waste and supporting the circular economy.
No Plastic Liners: Because dry ice sublimates, it doesn’t need plastic bags. Paper based CelluLiner packages protect goods up to 72 hours chilled and refrigerated y 48 hours frozen, eliminating plastic waste.
Drain Friendly Gel Packs: Innovations like IPC’s drain friendly packs use non toxic gel and curbside recyclable shells so recipients can rinse and recycle them. These packs help keep plastic out of landfills.
Reusable and Biodegradable Options: The Ice Cold Pack can be reused hundreds of times and contains biodegradable, non toxic gels, drastically reducing the number of single use packs thrown away.
Lower Water Usage: Dry ice production consumes less water than freezing conventional ice packs.
Reduced Carbon Emissions: Using renewable energy and on demand production technologies can lower the carbon footprint of dry ice manufacturing. Carbon capture and reuse technologies trap CO₂ emissions and convert them into dry ice, further reducing net emissions.
