What Is a Customized Dry Ice Pack Sheet?
A customized dry ice pack sheet is a flexible cooling pad engineered with specific dimensions, cell configurations and phase change materials to meet the unique thermal demands of your shipment. Unlike traditional block dry ice that sublimates unpredictably, these sheets combine small dry ice cells or PCM powder within sealed compartments surrounded by absorbent material. This structure provides controlled cold release, minimized CO₂ off gas and easier handling. Customization allows you to choose the number of cells (MISALNYA., 9sel, 12 cell or 24 cell sheets), the thickness of the core, the type of PCM and even eco friendly outer films.
Cara kerjanya
The sheet’s functionality comes from its multi layer design:
Lapisan pelindung luar: Typically made from polyethylene or PET film, the outer layer prevents punctures and contains CO₂ gas. Some designs use biodegradable or compostable films to reduce environmental impact.
Absorbent gel or PCM layer: Beneath the shell lies a layer of super absorbent polymers or PCM powder. When soaked in water and frozen, this layer stores latent heat and slows the sublimation of the dry ice, prolonging cold duration. Specialty PCMs can be selected to maintain temperatures from –21 °C to –78.5 °C.
Core containing dry ice cells: The core houses the dry ice or PCM blocks arranged in cells. This compartmentalisation spreads the cold evenly and reduces the risk of direct contact with the cargo. Cells can be sized or arranged to fit specific box dimensions.
When the sheet is activated (typically by soaking in water then freezing), the gel or PCM absorbs the water, freezes and locks the dry ice in place. Saat es kering menyublim, the stored latent heat moderates temperature fluctuations, maintaining ultra cold conditions over extended periods. Some sheets combine dry ice with gel packs to create a hybrid system that leverages the quick cooling of dry ice and the steady release of PCMs.
Key customization parameters
Ukuran dan bentuk: Sheets can be cut or manufactured to fit the footprint of your packaging. Typical formats include 28.5 × 25 cm (24sel) sheets for seafood and pharmaceuticals and smaller 18 × 12 cm sheets for meal kits.
Jumlah sel dan geometri: Common configurations are 9 sel (3 × 3), 12 sel (2 × 6) Dan 24 sel (4 × 6). A higher cell count increases flexibility and allows the sheet to wrap around irregular products.
Bahan perubahan fase: Custom PCMs determine the temperature range. Gel sheet dry ice packs can reach temperatures as low as –123 °C (–190 °F) ketika dibekukan, while dry ice replacement packs maintain –21 °C for 36–72 h.
Bahan luar: Customers can select non woven fabric, PE/PET film or biodegradable films. Dual side absorption designs prevent sticking and enhance heat transfer.

Tip dan saran praktis
Pre condition your sheet: Soak the pack sheet in water until the cells fully expand, then freeze it for at least 24 jam. This ensures the PCM reaches its target temperature and maximizes latent heat.
Layering matters: For extremely sensitive shipments, combine dry ice sheets with gel packs or eutectic plates. Place a layer of gel beneath or around the product to stabilize temperature, then add dry ice sheets to maintain ultra cold temperatures.
Hindari kontak langsung: Use a cardboard or insulating layer between the sheet and your product to prevent freezer burn. The cell design keeps dry ice contained, but adding insulation adds an extra safety buffer.
Studi kasus: A meal kit company replaced loose dry ice with 24 cell sheets. By customizing the sheet dimensions and cell count, mereka mencapainya 24 hours of –18 °C holding time without water residue and reduced shipping weight by 15 %, resulting in lower freight costs and fewer temperature excursions.
Why Choose Customized Dry Ice Pack Sheets?
Customized dry ice pack sheets offer consistent cold, improved safety and lower environmental impact compared with loose dry ice. Es kering menyublimkan langsung dari padatan ke gas, producing CO₂ that can displace oxygen in confined spaces. Replacing loose pellets with sealed cells reduces gas release and eliminates the need for special ventilation. Customizable sheets also provide more predictable temperature profiles and longer duration because the PCM layer slows sublimation and spreads cold evenly. For regulated industries, these sheets are classified as non hazardous in many jurisdictions, simplifying documentation and reducing shipping restrictions.
Advantages over loose dry ice and gel packs
Durasi pendinginan yang diperpanjang: Self cooling dry ice pack sheets can maintain sub zero temperatures for 36–72 hours, while some gel sheet packs reach even lower temperatures and last up to 72 jam.
Reduced CO₂ vapor release: Encapsulating dry ice in cells and using absorbent layers decreases off gassing and minimizes asphyxiation risks.
Less residue and mess: Unlike loose ice or gel packs that leak water, dry ice sheets sublime cleanly with minimal condensation, reducing the chance of soggy packaging and mold.
Reusability and flexibility: Many sheets are designed to be reused multiple times within their effective life. The flexible cell matrix allows you to wrap the sheet around oddly shaped items.
Lightweight and compact storage: Sheets are shipped flat and only expand when soaked, menghemat ruang penyimpanan. This results in lower freight costs compared with heavy eutectic plates.
Custom branding and sustainability: Modern sheets use biodegradable outer films and support custom printing. This demonstrates environmental responsibility and enhances your brand image
Economic and environmental context
The dry ice market is experiencing supply constraints due to limited CO₂ production; consumption grows at roughly 5 % per year while supply increases only 0.5 %, causing price spikes up to 300 %. Customized pack sheets mitigate these costs by using less dry ice and prolonging its cooling effect. Selain itu, cold chain stakeholders are facing pressure to reduce emissions. Substituting or supplementing dry ice with PCMs cuts CO₂ release and can lower energy consumption by up to 15 % when combined with AI optimized shipping routes. Choosing reusable, biodegradable sheets further aligns with sustainability goals.
Design and Components of Customized Dry Ice Pack Sheets
Three layer architecture
The effectiveness of a dry ice pack sheet comes from its three layer architecture: a protective shell, a PCM layer and a core. According to Tempk’s self cooling pack sheet design, the top outer layer prevents moisture accumulation and provides durability, the middle gel layer slows sublimation by absorbing latent heat, and the core houses dry ice that maintains ultra cold temperatures. This construction protects products from direct contact and extends cooling duration.
Material selection and performance
Different materials offer unique performance characteristics:
Gel based PCMs: Often water based with super absorbent polymers, these PCMs freeze at around 0 °C and remain at –18 °C to –21 °C for extended periods. They are safe, non toxic and ideal for food or pharmaceutical shipments.
Paket gel kriogenik: Using organic solvents or salts, these PCMs achieve very low phase change points and can reach –123 °C. They’re suitable for biologics and research materials that require deep freezing.
Pelat eutektik: Solid plates containing salt solutions that freeze at predetermined temperatures, offering consistent cold with minimal wear. They are heavier but can be recharged thousands of times.
Hybrid dry ice/PCM designs: These combine a small amount of dry ice with a gel PCM layer, delivering rapid cooling from dry ice and sustained cold from the PCM.

| Gel PCM | –21 °C to –1 °C | 36–72 jam | Vaksin, makanan, kosmetik |
| Cryogenic gel | –123 °C to –18 °C | Hingga 72 H | Biologi, sampel penelitian |
| Pelat eutektik | –30 °C hingga 0 ° C. | 48–96 h | Daging, susu, kit makan |
| Inti es kering | –78,5 °C | 24–48 h | Cryogenic shipments |
| Hybrid dry ice/PCM | –78.5 °C to –21 °C | 24–72 jam | Obat-obatan yang sensitif terhadap suhu |
Cooling mechanism explained
The cooling process begins when you freeze the sheet. Saat es kering menyublim, it absorbs latent heat from its surroundings, which reduces the temperature of the adjacent PCM layer. This layer slowly releases stored cold energy, moderating the temperature and extending the cooling effect. Because the dry ice is divided into small cells, the sheet maintains more uniform cooling and mitigates hot spots. Once all dry ice has sublimated and the PCM has warmed above its phase change point, the sheet returns to ambient temperature and can be reconditioned.
How to Select the Right Customized Dry Ice Pack Sheet
Selecting the optimal sheet requires evaluating product temperature requirements, Durasi Pengiriman, package dimensions and regulatory constraints. Berikut pendekatan langkah demi langkah:
Define your temperature goal: Determine the maximum allowable product temperature. Untuk vaksin dan biologi, this might be –70 °C (requiring dry ice or cryogenic gel), while for food shipments it may be –18 °C to 0 ° C..
Estimate transit duration: Identify how long the product will remain in transit, including last mile delivery. Dry ice replacement packs maintain sub zero temperatures for 36–72 hours; gel sheet dry ice packs can last up to 72 jam.
Calculate the required cooling mass: Use the formula recommended by Tempk to estimate dry ice quantity:
Dry ice weight = Product weight × (1 + Faktor musiman + Faktor rute + Faktor isolasi).
Seasonal factors account for ambient temperature (MISALNYA., menambahkan 0.3 for summer), route factors reflect time in transit, and insulation factors represent packaging quality.
Select sheet size and cell count: Choose a sheet that covers the surface area of your payload. Use multiple sheets to surround the product (sisi dan atas) if long durations are required. For irregular items, opt for 24 cell sheets for better flexibility.
Choose a PCM or hybrid design: Align the PCM’s phase change point with your temperature goal. For moderate cold (–21 °C), gel PCMs suffice, while deep frozen cargo may need cryogenic gel or hybrid designs. A hybrid sheet reduces total dry ice consumption while still achieving ultra low temperatures.
Consider branding and sustainability: Opt for biodegradable films or custom printing to communicate handling instructions and promote your brand. Sustainability is a key differentiator for customers in 2025.
Layering strategies
There are three common ways to position customized sheets inside packaging:
Pemuatan teratas: Place the sheet on top of the product. Udara dingin tenggelam, making this efficient for short routes and goods that can tolerate some temperature gradient.
Surround loading: Line the sides and bottom of the container with sheets. This method achieves uniform temperature and is suitable for longer transit times.
Hybrid loading: Combine top and surround strategies. Untuk kargo sensitif, place one sheet on top and additional sheets along the sides to ensure consistent temperature and extended duration.
