They ship flat for compact storage and are described as durable and reusable, suitable for both ground and air shipping. The packs are marketed as TSA-compliant for certain travel scenarios when frozen solid prior to transport, and they are designed for reuse to maximize cost efficiency. The product is intended to work in a variety of packaging configurations, including coolers, insulated boxes, and lunch bags, by providing a non-messy alternative to traditional ice.
ICE OWL Non-Stick Dry Ice Packs (5 Sheets)
ICE OWL’s non-stick, double-sided absorption sheets are designed to reduce sticking as they absorb moisture. Each sheet features four large cells per sheet, enabling substantial cold retention with a total weight around three pounds per sheet. Tests from TUV and SGS support non-stick performance. The design aims to extend cooling duration to approximately 18.5 hours within a 0-10°C (32°F-50°F) range, helping maintain freshness for fruits, vegetables, dairy, and other perishables. These sheets are compatible with coolers, lunch bags, and insulated shipping containers, and come in a 5-sheet pack that can be expanded with additional sheets if needed.
ICE OWL Dry Ice Packs For Shipping (10 Sheets)
This extended set from ICE OWL provides ten sheets, each with the same non-stick and high-absorption characteristics as the 5-sheet option. The multi-sheet configuration increases cooling capacity for larger shipments or when multiple units need to be kept cold for longer durations. The design emphasizes long-lasting cooling performance, moisture management, and compatibility with common shipping containers. The sheets are described as not containing dry ice and as a safe, non-toxic cooling option that minimizes leakage and mess in transit.
TarppedRock Dry Ice Packs For Shipping (10 Sheets)

Users can determine the number of sheets needed based on temperature, product type, and packaging size.
MR.ICE Shipping Ice Pack Sheets
MR.ICE offers reusable ice pack sheets designed for easy preparation and long-lasting cooling. To activate, soak the full ice pack in water for 2-3 minutes, then drain and dry the surface before freezing. The product emphasizes suitability for lunch bags, coolers, and insulated bags, providing a dry, non-wet cooling option that avoids leaking in transit. It is marketed as not containing Dry Ice, with a focus on preventing sticking and ensuring consistent cooling across a variety of shipping setups.

Buying Guide: Key Considerations For Choosing Dry Ice Alternatives
When selecting a cooling solution for shipping perishables, consider the following factors to ensure safe, effective, and cost-efficient performance:
- Cooling duration: Determine the typical transit times and required cold stability. Some packs advertise 24-hour performance, others up to 72 hours in certain conditions. Align duration with your average shipping window.
- Container compatibility: Assess whether sheets fit in lunch bags, coolers, insulated shipping boxes, or larger crates. Flexible sheets that can be cut to size offer greater packing versatility.
- Activation method: Most products require soaking in water to activate and expand. Consider the ease of use, drying requirements, and whether the surface stays dry after activation.
- Reusability: Reusable packs can reduce long-term costs, but confirm durability and whether reuse affects cooling performance over time.
- Safety and compliance: Ensure the product is non-toxic, does not produce moisture leakage, and complies with travel guidelines if shipping by air with restricted liquids.
- Non-stick and moisture management: Sheets with non-stick properties help prevent materials from sticking during freezing and thawing, while moisture control minimizes unwanted condensation inside packaging.
- Storage and prep: Look for packs that ship flat or compactly, and require minimal prep before use to save time during packing.
Additional factors to consider include environmental impact (reusability and washability), cost per use, and the availability of multi-pack options to scale with order size. For high-velocity shipments of perishable foods, a combination of sheets and larger packs may offer the best balance of coverage and portability.
