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 (gelo seco) ou materiais de mudança de fase (PCMs) 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.), fornecendo estável, ultra cold conditions necessary for sensitive shipments. Porque sublima, 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, transformando gás residual em um refrigerante útil.
Why they are better than traditional options
Resíduos plásticos reduzidos: Traditional gel packs require plastic shells that often end up in landfills. Dry ice eliminates that need and relies on reusable, recipientes isolados.
Menor pegada de carbono: Dry ice is a by product of industries like ammonia and ethanol production, meaning its use repurposes existing CO₂ rather than generating new emissions.
Consumo mínimo de água: Producing ice or gel packs uses considerable water. Dry ice is created without water, conservando recursos.
Recyclable and Biodegradable: Porque o gelo seco sublima completamente, 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, produtos de alta qualidade.
