Environmentally Safe Non-Toxic Sodium Polyacrylate Ice Pack with Long-Lasting Cooling Performance
Environmentally Safe Biodegradable Gel Ice Packs are cooling packs formulated with sodium polyacrylate (CAS No. 9003-04-7) as the core water-absorbing and gel-forming material. The polymer rapidly absorbs water and converts it into a stable gel, delivering long-lasting, consistent cooling performance. Designed with environmental responsibility in mind, these gel ice packs are suitable for cold chain logistics, food & beverage transport, pharmaceutical shipping, medical use, and personal cooling applications.
- High Water Absorption & Stable Gel Formation: Sodium polyacrylate absorbs hundreds of times its own weight in water, forms a uniform, leak-resistant gel after hydration, and maintains structure even after repeated freezing and thawing cycles
- Long-Lasting Cooling Performance: Provides extended cooling duration compared with traditional ice, slow melting rate ensures stable temperature control, ideal for refrigerated and frozen transportation
- Non-Toxic & Safe for Contact Applications: Non-toxic polymer formulation, suitable for food, pharmaceutical, and medical cold chain use (non-direct consumption), odorless and clean to handle
- Flexible Customization: Available in various sizes, shapes, and gel concentrations, cooling duration and gel strength can be adjusted according to application needs, compatible with PE, PA, or composite outer packaging
- Food & Fresh Produce Cold Chain
- Pharmaceutical & Vaccine Transportation
- Laboratory Sample Shipping
- Medical & First-Aid Cooling Packs
- Reusable Personal & Outdoor Cooling
Sodium polyacrylate is the core absorbent polymer. It absorbs water and forms a stable gel that stores cold efficiently and releases it slowly, ensuring long-lasting cooling.
The gel is non-toxic and environmentally safe, but it is not edible. If leakage occurs, clean with water and dispose of according to local waste regulations.
Yes. They are designed for multiple freeze-thaw cycles without significant loss of cooling performance or gel integrity.
The product is formulated with eco-friendly and biodegradable design principles. Actual biodegradation performance may vary depending on disposal conditions and local standards.
When fully frozen, they typically maintain temperatures between 0 °C to −18°C, depending on gel formulation, pack size, and freezer conditions.
Yes. Gel concentration, pack thickness, and size can all be customized to achieve specific cooling durations and performance targets.
Yes. It is widely used for pharmaceutical, vaccine, and biotech cold chain logistics, provided it is used with appropriate secondary packaging and validation.
