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, توفير مساحة, and can be cut to fit any container. The gel cells act as extra insulation, trapping cold air next to the product. عندما تجميد, 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. على سبيل المثال, Techni Ice packs are manufactured under ISO 9001 certification and have full FDA approval.
طاولة 1 – Comparing Gel Cell Sizes and Hydrated Weight
| منتج | 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 الخلايا) | 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 |
نصائح ونصيحة عملية
ترطيب – 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.
التجميد – 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.
إعادة الاستخدام – Many gel sheet dry ice pack sheets are reusable. بعد الاستخدام, 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. Dry ice is extremely cold (–109.3 °F/–78.5 °C) and sublimates directly from solid to gas, دون ترك أي بقايا سائلة. While this makes it ideal for keeping products frozen for long periods, it also means dry ice can damage items that cannot tolerate freezing. حزم هلام, على الجانب الآخر, maintain temperatures around 32 ° f (0 درجة مئوية) 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
البضائع المجمدة (–20 °C to –40 °C) – For products that must remain frozen, مثل الآيس كريم, 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.
البضائع المبردة (2 °C to 8 درجة مئوية) – For dairy, الشوكولاتة, 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.
شحنات مختلطة – 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. استخدام القفازات المعزولة, tongs and eye protection when handling dry ice. Dry ice should be stored in insulated containers and never tightly sealed due to gas buildup.
تهوية – 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.
أنظمة – 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.
