What Defines a Near Me Dry Ice Pack Sheet and Why Does It Matter?
Definition and Key Benefits
A dry ice pack sheet is a flexible coolant filled with either solid CO₂ pellets or super absorbent polymer (SEIVA) cells that freeze to form a rigid blanket. Ao contrário de pellets soltos, sheets wrap around your product like a blanket, improving “edge coverage” and reducing warm corners. Traditional gel packs operate at 0–5 °C and melt into water, while dry ice sheets maintain temperatures down to –78 °C without leaving a liquid mess. Em 2025, many shipping programs adopt sheets because they pack tightly in odd shaped boxes, weigh less than blocks and meet varying temperature bands when combined with gel packs or PCMs.
As principais vantagens incluem:
Ultra low temperature without residue – O gelo seco sublima diretamente em gás, so there’s no water to damage goods.
Flexible coverage – Sheets wrap around product walls for uniform cooling and fewer warm spots.
Maior duração – With proper thickness and insulation, sheets can maintain frozen temperatures for 24–72 hours.
Reduced handling risk – Compared with loose pellets, sheets minimize blow off of CO₂ and are easier to remove.
Conformidade simplificada – Water based SAP sheets avoid hazardous material labels, whereas true dry ice (CO₂ sólido) requer ONU 1845 labels and Class 9 marcações de perigo.
How Dry Ice Sheets Compare with Gel Packs and PCM Blocks
The table below summarises key differences between dry ice pack sheets, pacotes de gel e materiais de mudança de fase (PCM) to help you choose the right coolant for your lane.
| Tipo de refrigerante | Faixa de trabalho | Duração típica | O que isso significa para você |
| Folha de gelo seco (SEIVA) | Em volta 0 °C quando hidratado; sub zero when using CO₂ cells | 12–48 horas para remessas refrigeradas, 24–72 h for frozen when paired with insulation | Lençóis leves envolvem formas estranhas; menor custo; easier to deploy and dispose than PCMs. |
| Tijolos ou telhas PCM | −25 °C a +25 °C dependendo da formulação | 24–96 h | Fornece controle rígido de temperatura para auditorias; maior custo inicial; requer pré-condicionamento (freeze or heat). |
| Pacotes de gel / tijolos de gelo | 0 °C a 5 °C | 8–24 h | Simples, inexpensive and ideal for chilled goods; melt into water and can leak; not suitable for sub zero shipments. |
Cenários Práticos
Entregas de kit refeição – For a 36 hour lane shipping frozen meals, wrap the sides with a 0.5 inch sheet and add an extra top sheet. A regional meal brand using this pattern kept chicken entrées below –10 °C for 60 hours and cut customer complaints by two thirds.
Remessas farmacêuticas – For vaccine kits requiring –20 °C, usar 1 inch thick sheets and add a breathable divider to avoid vial cracking. Record lot numbers for traceability.
Mixed temperature loads – Pair gel packs on top with dry ice sheets hugging frozen items to create dual zones.

Large retailers and industrial gas companies often stock dry ice, especially in states where cold shipping is common. Walmart e Home Depot carry dry ice and sometimes pre cut sheets in their freezer section. Gás aéreo e Praxair supply dry ice in various forms (rice pellets, standard pellets and blocks) and allow online ordering for local pickup. Airgas also emphasises quality control: they rotate stock first in, first out and ship products in traceable, stainless steel lined containers to reduce sublimationairgas.com.
Visit Pharmacies, Groceries and Ice Manufacturers
Smaller quantities may be available at local pharmacies or grocery stores, which sometimes keep dry ice for shipping medical samples. Local ice manufacturers also cut blocks and slabs and may supply custom sized sheets. Bear Ice Company describes how dry ice slabs, pellets and medical grade pellets serve both commercial and personal needs, from cooling large quantities of food to creating fog for events. They note that dry ice is ideal for power outages, hunting/fishing trips, biological sample transport and even stage effects.
Consider Specialty Cold Chain Providers
Se você envia regularmente, build a relationship with a dedicated cold chain supplier. These providers can customise sheet sizes, oferecer compras em massa e garantir disponibilidade consistente. They may also provide training, insulation kits and performance data loggers. Companies like Tempk design kits with printed pack out cards and hydration guides so that every box is packed correctly.
Dimensionamento e embalagem: How Many Sheets Do You Need?
Proper sizing ensures that your payload stays frozen without waste. Em geral, choose sheet thickness based on route duration and environment. The rules below simplify the process:
Match sheet length to box walls – For a 12×10×8 inch cooler, cut or fold sheets to line all four walls and the bottom. Add a top sheet for long routes.
Select thickness by duration – Start with 0.5 inch thick sheets for 24–36 hour shipments; mudar para 1.0 inch sheets for 48 horas e 1.25 inch sheets for 72 horas.
Use more plies than thickness – Adding extra layers around the sides often improves hold time more than simply increasing thickness.
Planeje um buffer – Add 20 % time to account for courier delays and hot weather.
Record key data – Before shipping, log payload mass, ambient profile, tipo de isolamento, sheet thickness and count.
Below is an approximate relationship between sheet thickness and hold time, based on typical performance. Always validate with your products and lanes.
Mesa: Sheet Coverage and Purpose
| Cobertura | Uso típico | O que isso significa para você |
| 4 wall panels | All routes | Minimizes “hot spots” and evens out temperature. |
| Folha superior (1–2 painéis) | 48–72 h lanes | Adds insurance against courier delays. |
| Folha inferior (1 painel) | All routes | Protege contra pisos quentes de caminhões e reduz o derretimento. |
User Tips for Packing
Pré-resfrie tudo – Cool the shipper and payload before adding sheets so they don’t waste energy lowering the temperature.
Enrole e depois tampe – Line sides first, carregar produto, then place the top sheet. This “no crush” pattern protects fragile items like vials.
Evite lacunas – Use dunnage or foam to eliminate headspace and prevent sheets from shifting.
Teste piloto – Run a 10 box pilot under your worst case conditions (ondas de calor, fins de semana prolongados). Adjust coverage based on arrival temperatures.
Imprimir cartões de embalagem – Place step by step instructions inside each kit to reduce training time and ensure consistency.
Exemplo de caso: A regional hospital ran a pilot using 1.25 inch sheets to supply clinics 1,000 quilômetros de distância. By combining full wall coverage, a top booster sheet and printed pack out cards, they maintained –15 °C for 72 horas sem excursões, allowing them to safely ship biologics without overnight freight.
Segurança: Manuseio, Armazenar, Transporte & Disposição
Dry ice is extremely cold and releases carbon dioxide gas. To protect people and products, follow these safety principles from carriers and university safety departments.
Diretrizes de manuseio
Proteção contra desgaste – Use insulated gloves and eye protection; avoid direct skin contact to prevent frostbite. The University of Edinburgh warns that dry ice can cause cold burns and frostbite, and even short exposure may be hazardous.
A ventilação é crítica – Use dry ice only in open or well ventilated areas to prevent CO₂ buildup. Concentrações de CO₂ acima 5,000 ppm durante oito horas ou 15,000 ppm acima 15 minutos excedem os limites de exposição no local de trabalho.
Never seal it – Do not put dry ice in airtight containers; pressure can build and cause an explosion. FedEx 2025 job aid specifies using fibreboard, caixas de plástico ou madeira com orifícios de ventilação, and prohibits sealed plastic bags.
Use tools – Handle pieces with tongs or scoops; avoid leaning into storage bins and keep lids closed when not in use.
Melhores práticas de armazenamento
Escolha o recipiente certo – Use insulated boxes that allow gas to escape. FedEx prohibits steel drums and recommends polystyrene foam only as inner insulation, not as outer packaging.
Avoid sealed rooms – Do not store dry ice in freezers, refrigerators or unventilated rooms. Keep containers in dry, well ventilated spaces away from heat sources.
Girar estoque – Follow first in, first out rotation to reduce sublimation and avoid using old sheets; Airgas emphasises this practice for quality controlairgas.com.
Secure access – Store dry ice in a secure area and prevent unauthorized access, especially children or untrained personnel.
Transport Requirements
Rotulagem adequada – If using solid CO₂ sheets, mark packages with “Dry Ice” or “Carbon Dioxide, sólido,”a ONU 1845 número e peso líquido. FedEx requires a Class 9 hazard label measuring at least 100 mm de lado.
Embalagem ventilada – Ensure boxes vent gas; use holes or vent plugs when using plastic coolers.
Carrier limits – FedEx caps dry ice at 200 kg per package and instructs shippers to confirm allowed quantities for air shipments. Carriers may have separate weight limits for ground and air lanes.
Never transport in closed vehicles – University guidelines warn against carrying dry ice in passenger compartments; ventilate using outside air if transport is unavoidable.
Disposição: Responsible and Legal Practices
Permitir sublimação – The safest way to dispose of dry ice is to let it sublimate in a well ventilated outdoor area. Dry ice sublimates directly from solid to gas at –78 °C.
Avoid sealed bins – Never throw dry ice packs into trash bins, pias ou vasos sanitários; sealed spaces can trap gas and cause pressure buildup or suffocation.
Use disposal facilities – Some hazardous waste facilities accept dry ice; call ahead to verify.
Hire professionals for large volumes – For large quantities or urgent disposal, consider hiring a disposal service that can neutralise dry ice safely.
How to Buy Dry Ice Pack Sheets Near You: Step by Step Plan
Define your lanes and goals. Map out your top three shipping lanes and target arrival temperatures, such as “below –10 °C for 72 horas."
Escolha uma especificação inicial. Comece com 1 inch walls and a top sheet plus a printed pack out card; adjust thickness after pilot tests.
Locate suppliers. Use ferramentas de pesquisa, check retailers, contact gas companies and engage a cold chain specialist.
Execute um piloto. Enviar 10 boxes along your toughest lane and log temperatures with inexpensive data loggers.
Tune the specification. Adjust coverage based on failures—add a top booster sheet or increase thickness for hot climates.
Abra e treine. Imprimir cartões de embalagem, train staff and implement first in, first out rotation. Standardisation reduces errors and speeds packing.
Track and optimise costs. Calculate cost per successful delivery, including material, trabalho, freight and spoilage. Thicker sheets that prevent one failed order can save double digits in overall cold cost per kilogram.
Cost Model Example
Successful Delivery Cost = (Sheet Cost + Caixa + Trabalho + Frete + Rótulos)
+ (Failure Rate × (Product Cost + Re ship + Atendimento ao Cliente))
If a thicker sheet cuts failures from 4 % para 1 %, your total delivery cost often drops, freeing budget for marketing or R&D.

Regulations ensure shipments are safe for workers, transportadores e destinatários. Em 2025, compliance focuses on labeling, treinamento e documentação.
Classificação de perigo – True dry ice is a Class 9 hazardous material with UN 1845 designação. Os pacotes devem exibir o nome de remessa adequado, UN number and weight on the same surface as the hazard label. Sheets containing only water and SAP avoid this classification but still require food contact compliance for edible goods.
Marcação e rotulagem – FedEx requires the shipper’s and recipient’s names and addresses on the package; labels must be at least 12 mm high when the package holds over 30 kg de gelo seco. Uma aula 9 label with seven vertical stripes must be attached; do not write on the label.
Documentação – Air bills must state “UN 1845, Gelo Seco” e liste o número de embalagens e o peso líquido. Trained staff must prepare shipments and abide by dangerous goods regulations; carriers offer seminars and phone support.
Segurança no trabalho – The University of Edinburgh lists CO₂ exposure limits: 5,000 ppm over eight hours and 15,000 ppm acima 15 minutos. Only trained, competent users should handle dry ice; risk assessments must be followed. Additional guidelines cover transportation in lifts and vehicles.
