How Do Gel Sheet Dry Ice Pack Sheets Work and Why Are They Different?
Gel sheet dry ice pack sheets merge the benefits of dry ice and conventional gel packs, providing intense cooling in a flexible sheet that can be hydrated and cut to size. Unlike solid blocks of dry ice, each sheet contains cells filled with a super absorbent polymer. When soaked in water, the powder swells into a gel that is sealed within the cells, creating a quilted blanket of refrigerant. One side of the sheet is made of permeable fabric which allows water to penetrate and activate the polymer, while the other side features a durable plastic layer to prevent leakage.
Once hydrated, the gel is trapped, making the sheet pliable and easy to wrap around products. Dry gel ice sheets are less expensive per pound when hydrated, cheaper to ship when dehydrated, and more effective at maintaining uniform cold compared with loose gel packs. They ship flat, Salvando espaço, and can be cut to fit any container. The gel cells act as extra insulation, trapping cold air next to the product. Quando congelado, the sheets perform similarly to dry ice, achieving extremely low temperatures (Techni Ice sheets can be frozen down to –190 °F). This unique combination of flexibility, cost effectiveness and powerful cooling sets gel sheet dry ice pack sheets apart.
Understanding Materials and Construction
Gel sheet dry ice pack sheets rely on non toxic polymers and multi layer films:
Polymer composition – The gel inside most ice packs is a water absorbing polymer such as sodium polyacrylate or silica gel. Techni Ice uses a cross linked polyacrylate polyalcohol copolymer combined with a proprietary post treated refrigerant.
Multi layer structure – A typical sheet comprises two inner layers of high strength spun bonded synthetic fabric for strength and abuse resistance, and two outer layers of printed PET/LDPE laminate for printability and heat sealability. One way micro perforation technology allows water to enter during hydration while preventing leakage.
Non toxic and food safe – Most gel packs are made with non toxic materials approved for food contact. Por exemplo, Techni Ice packs are manufactured under ISO 9001 certification and have full FDA approval.
Table 1 – Comparing Gel Cell Sizes and Hydrated Weight
| Produto | Dry cell size | Hydrated weight (approx.) | Practical benefit |
| Thermapack #337 Dry Gel Ice Sheet (3 oz cells) | 3 × 3.7 in flat; 6 cells per row | 33 foot sheet yields ~36 37 lb of gel ice when hydrated (ships flat at ~2 lb) | Smaller cells provide flexible coverage for delicate items |
| Thermapack #637 Dry Gel Ice Sheet (8 oz cells) | 6 × 3.7 in flat; 3 cells per row | 33 foot sheet yields ~49 50 lb of gel ice when hydrated (ships flat at ~2 lb) | Larger cells last longer in extreme conditions |
| Techni Ice HDR sheet (24 células) | Flat sheet; cells swell when hydrated | Cells expand to form 24 individually sealed pockets; can be cut to size | Provides flexibility and uniform cooling for custom containers |
Dicas e conselhos práticos
Hidratação – Immerse the sheet in warm water for 5–15 minutes until air bubbles stop; the cells will swell as water activates the polymer. Techni Ice sheets absorb water through one way perforations and should be hydrated until fully expanded.
Congelando – After hydration, lay the sheets flat in a freezer. Techni Ice packs can reach –0.4 °F to –5.8 °F in domestic freezers and even –190 °F in blast freezers.
Cutting and wrapping – Cut along the seams to fit the sheet around your product. The quilted structure keeps gel cells evenly distributed. Wrapping the sheet tightly around goods maximizes surface contact.
Reutilização – Many gel sheet dry ice pack sheets are reusable. Após o uso, thaw completely, wipe dry, and refreeze. Inspect for punctures before reuse.
Case Example: A specialty cheese producer switched from loose gel packs to 3 oz gel sheet dry ice pack sheets for summer shipments. By hydrating and freezing the sheets overnight, then cutting them to wrap each wheel, they maintained consistent 2–8 °C temperatures during transit and reduced refrigerant weight by 20%. Customers reported fewer temperature fluctuations and less condensation.
When Should You Choose Gel Sheet Dry Ice Pack Sheets Over Conventional Dry Ice or Gel Packs?
Choose gel sheet dry ice pack sheets when your shipment requires intense cooling but also flexibility, shape conformity and reduced mess. Gelo seco está extremamente frio (–109.3 °F/–78.5 °C) and sublimates directly from solid to gas, não deixando resíduos líquidos. While this makes it ideal for keeping products frozen for long periods, it also means dry ice can damage items that cannot tolerate freezing. Pacotes de gel, por outro lado, maintain temperatures around 32 °F (0 °C) and are better for chilled goods. Gel sheet dry ice pack sheets bridge the gap: they can be frozen to extreme temperatures like dry ice, yet they remain flexible and cuttable like gel packs. This makes them suitable for mixed shipments and for packages that need to maintain uniform cooling without direct contact with carbon dioxide gas.
Choosing the Right Refrigerant for Your Shipment
Produtos congelados (–20 °C to –40 °C) – For products that must remain frozen, como sorvete, sorbet or frozen meat, dry ice or gel sheet dry ice pack sheets are appropriate. Dry ice lasts longer but requires careful handling and regulatory compliance. Gel sheet dry ice pack sheets can achieve similar low temperatures while providing a more even wrap around the product, reducing cold spots.
Produtos refrigerados (2 °C a 8 °C) – For dairy, chocolates, cosmetics and pharmaceuticals that should not freeze, gel packs or hydrated gel sheets are better. Gel sheet dry ice pack sheets maintain the 2–8 °C range and can be used at room temperature to protect items from freezing.
Mixed shipments – If your shipment contains both frozen and chilled items, combine gel sheet dry ice pack sheets with dry ice. Cold packs slow the sublimation of dry ice, extending the cooling duration.
Regulatory considerations – Dry ice is classified as a hazardous material in the U.S. for shipments above 5.5 lb and requires special labeling and ventilation. Gel sheet dry ice pack sheets are not regulated as hazardous materials and are easier to transport.
Handling and Safety Considerations
Handling both dry ice and gel sheets requires attention to safety:
Avoid direct contact with dry ice – The extreme cold of dry ice can cause frostbite within seconds. Use insulated gloves, tongs and eye protection when handling dry ice. Dry ice should be stored in insulated containers and never tightly sealed due to gas buildup.
Ventilação – As dry ice sublimates into carbon dioxide gas, adequate ventilation is crucial to avoid asphyxiation. Gel sheet dry ice pack sheets do not release gas, making them safer in enclosed spaces.
Disposal and recycling – When disposing of gel sheet dry ice pack sheets, thaw them completely. The gel is non toxic but should not be flushed down drains; small amounts can go in the trash, sealed in a bag. The plastic film may be recyclable depending on local programs.
Regulamentos – Shipments of dry ice must comply with 49 CFR or IATA regulations above certain weights. There are no special regulations for gel sheet dry ice pack sheets, simplifying logistics.
Table 2 – Pros and Cons of Refrigerant Options
| Refrigerant type | Faixa de temperatura | Vantagens | Limitations |
| Gelo seco | Maintains –109 °F (–78,5 ° C.) | Extremely cold; long cooling duration; leaves no liquid residue | Requires insulated gloves and ventilation; regulated as hazardous above 5.5 Libra; may freeze sensitive goods |
| Pacotes de gel | Around 32 °F (0 °C) | Ideal for chilled goods; no special handling; reutilizável | Cannot keep products frozen; may produce condensation |
| Gel sheet dry ice pack sheets | Can reach –190 °F in blast freezers and maintain 2–8 °C for chilled goods | Flexível, cuttable, cost effective to ship and store; non hazardous; reduces mess; can substitute for dry ice | Requires hydration; may not last as long as dry ice in some applications |

How to Use Gel Sheet Dry Ice Pack Sheets Correctly and Efficiently
Proper preparation of gel sheet dry ice pack sheets ensures optimal performance and minimizes waste. Follow these steps:
Hydrate the sheet – Soak the dry sheet in warm water for 5–15 minutes (or until all air bubbles escape) so the polymer absorbs water. Techni Ice recommends immersing the sheet until cells swell fully.
Drain excess water – After hydration, pat the sheet dry to remove surface moisture. Leaving moisture can lead to ice crystals forming on the outside of the pack.
Freeze thoroughly – Place the hydrated sheet flat in a freezer. For extreme cold, use a blast freezer (down to –190 °F); for everyday use, a domestic freezer set to its lowest temperature will freeze the sheet to –0.4 °F to –5.8 °F.
Cut and pack – Once frozen, cut along the seams to fit your container. Wrap products snugly to maximize contact, or line the shipping box walls to create a cooling barrier.
Combine with other refrigerants when necessary – For long durations or extremely frozen shipments, combine gel sheet dry ice pack sheets with dry ice or PCMs to extend the cooling period.
Reuse or dispose responsibly – After use, thaw the sheet. If reusable, rehydrate and refreeze. If disposing, follow local guidelines: the gel is non toxic but should be sealed and placed in the trash, and any recyclable plastic films should be sent to appropriate facilities.
