What Are Dry Ice Bricks and Dry Ice Packs, Dan mengapa mereka penting?
Dry ice bricks and dry ice packs are both made from solid carbon dioxide (Co₂) itu Subledlimates directly into gas without melting. This means no water residue, making them ideal for shipping frozen foods, pharmaceuticals and laboratory samples. Dry ice bricks are rigid blocks that sublimate slowly and provide long lasting cooling, ketika dry ice packs are flexible sheets, pellets or slices designed for faster cooling and easier placement. Because dry ice’s temperature is approximately −78,5 °C (−109 °F), it offers three times the cooling efficiency of water ice. Choosing the right form keeps your products safe, reduces waste and helps you comply with shipping regulations.
Forms, Sizes and Cooling Mechanisms
Dry ice comes in different forms to match various logistics needs:
| Form | Typical Size | Tingkat sublimasi | Apa Artinya bagi Anda |
| Blok | Besar, dense slabs | Lambat (48–72 h in insulated boxes) | Ideal for long distance shipments; lower surface area means heat is absorbed slowly. |
| Pelet (beras) | Small cylinders (~1/8–3/8 in.) | Cepat (12–24 h) | Provide precise cooling and fill gaps; often used in laboratories and dry ice blasting. |
| Slices/Nuggets | Medium sized pieces | Sedang | Fit tight spaces; useful for small packages or field kits. |
| Pre made packs | Enclosed pellets in vented packaging | Variabel | Designed to release CO₂ gas slowly around products, keeping them cold without direct contact. |
Batu bata es kering are heavy and cumbersome to lift, but they maintain temperatures longer than pellets. Paket es kering are easier to handle and can be arranged around irregular products, but they may need replacement sooner.
Practical User Tips and Advice
For long trips and heavy loads: Use dry ice bricks or large industrial packs. Their slow sublimation keeps cargo frozen for days.
For precision cooling or small packaging: Use pellets or slices to fill spaces and ensure even cooling.
Combine forms when necessary: Mixed shipments can combine bricks for frozen goods and gel packs for chilled items.
Kasus aktual: A seafood exporter replaced water ice with small dry ice slices. By venting insulated boxes and placing packs correctly, perusahaan reduced shipment weight by 30 % and kept fish fillets frozen for 48 hours without leakage.
Choosing Between Dry Ice Bricks and Dry Ice Packs: Factors to Consider
Selecting the right cooling agent depends on shipment duration, product requirements and customer experience. Batu bata es kering excel for long durations (48+ jam) and heavy loads; they maintain ultra cold temperatures below −70 °C and are essential for vaccines, frozen meat or biologic samples. Paket es kering work well for shorter trips or smaller packages and are easier for customers to handle. Gel packs or phase change materials may be preferable when goods need to remain chilled rather than frozen.
Product Temperature Requirements
Different products have distinct temperature needs:
Barang beku (es krim, hidangan laut, vaksin): require ultra cold conditions; dry ice sublimates at −78.5 °C ensuring these items stay frozen.
Chilled goods (cokelat, medicines requiring 2–8 °C): gel packs or phase change materials are more suitable because they maintain temperatures above freezing.
Durasi dan jarak pengiriman
Long distance shipments or routes through warm climates favour dry ice bricks, which last 48–72 hours. Local deliveries or same day shipments can rely on gel packs or smaller dry ice packs. Equal weight of dry ice and payload can keep items frozen for up to 48 jam, Dan 1.5× the weight may be needed for 72 jam.
Handling and Regulatory Compliance
Dry ice is classified as Dan 1845 under hazardous materials by the Asosiasi Transportasi Udara Internasional (Iata) dan AS. Departemen Transportasi (DOT). Shipments exceeding 5 lbs require labeling with “Dry Ice (Karbon Dioksida Padat) UN 1845” and weight declaration. Gel packs are not regulated and therefore easier for customers to handle.

Use robust outer packaging: Corrugated cardboard or heavy duty plastic boxes provide strength; avoid steel drums or sealed plastic containers.
Safety Precautions and Regulatory Considerations
Kenakan perlengkapan pelindung: Gunakan sarung tangan terisolasi, goggles and closed toe shoes to avoid frostbite.
Pastikan ventilasi: One pound of dry ice releases about 250 Liter Gas CO; store and handle in well ventilated areas.
Label packages: Mark shipments with “Dry Ice (Karbon Dioksida Padat) UN 1845” and include net weight to comply with DOT/IATA rules.
Avoid incompatible materials: Metals, plastics or glass can crack at extreme cold; use containers rated for dry ice.
Train handlers and customers: Provide instructions for safe use and disposal; untrained staff may mishandle dry ice and risk frostbite or asphyxiation.
Pembuangan: Allow dry ice to sublimate in open space; never dump it in sinks or drains.
Kasus aktual: A biotech lab packed 15 lbs es kering in pre chilled containers with ventilation holes for a 24 hour flight, pencapaian −70 °C throughout transit without pressure buildup.
Kesalahan umum untuk dihindari
Sealing containers completely – traps CO₂ and can cause explosions.
Underestimating dry ice quantity – leads to thawing; adjust for ambient temperature and travel time.
Contacting water – speeds up sublimation; keep dry ice dry.
Skipping training – untrained staff may neglect ventilation and protective gear.
Penanganan yang aman, Packaging and Disposal
In addition to the guidelines above, ensure your operation meets regulatory standards:
Regulatory classification: Es kering adalah Kelas 9 bahan berbahaya (Dan 1845); shipments require labeling and documentation.
Air transport restrictions: IATA limits dry ice to 200 kg per package on passenger aircraft.
Postal regulations: AS. Postal Service allows dry ice shipments domestically but restricts them to 5 pon per paket, whereas FedEx or UPS allow larger shipments with appropriate documentation.
