Description
Ice-Brix™ Cold Packs are premium gel-based cooling elements engineered for reliable temperature maintenance during shipment of temperature-sensitive products. These leak-proof cold packs are the industry standard for pharmaceutical, food service, medical device, and perishable goods logistics.
Each pack measures 6″L x 4″W x 3/4″H and contains 8 ounces of non-toxic refrigerant gel capable of maintaining consistent cooling performance across extended shipping windows. The durable plastic exterior in white/blue design resists punctures and provides clear visual identification within shipping containers. This bulk 36-pack offering delivers cost-effective temperature control for high-volume shippers managing multiple shipments daily. The sealed construction prevents gel leakage onto products, packaging materials, or shipping documentation—critical for maintaining product integrity and regulatory compliance. When pre-frozen to proper temperature, these packs maintain effective cooling for 24–48 hours depending on ambient conditions and insulation methods.
Temperature-controlled shipping relies on strategic cold chain management, and Ice-Brix™ packs serve pharmaceutical companies, clinical laboratories, blood banks, vaccine distributors, seafood processors, and specialty food retailers. Biologics shippers depend on these packs to maintain 2–8°C ranges for medications and biologics. Perishable food logistics providers use them for fresh seafood, dairy, and prepared meal delivery. Medical device manufacturers ship temperature-sensitive diagnostics and implantable products. Laboratory supply chains require consistent cooling for sample preservation. Direct-to-consumer shippers of meal kits, supplements, and specialty foods incorporate these packs into insulated packaging systems.
When selecting reusable cold packs for your operation, evaluate freeze time requirements—how long packs must remain frozen before deployment; cooling duration—sustained temperature maintenance needed in transit; pack density within your insulated container—optimal spacing prevents product freeze-damage while maximizing efficiency; and regulatory requirements specific to your industry. Consider whether your operation needs bulk cold pack ordering to support consistent inventory rotation. Verify that packs meet FDA compliance for food-contact applications if products may touch gel surfaces. Assess your freezer capacity to pre-freeze sufficient packs for peak shipping periods. For hazardous materials shipping, confirm that gel composition complies with DOT and international transport regulations.
What size ice pack do I need for my shipping requirements?
The 6″L x 4″W x 3/4″H Ice-Brix™ pack is engineered for small-to-medium insulated shipping boxes (typically 4″x6″x4″ to 8″x6″x6″ interior dimensions). For single-item shipments or items under 2 lbs., typically one 8 oz. pack suffices. Larger shipments or longer transit times may require 2–4 packs strategically positioned. Reference our cold chain design guidelines for your specific product weight, destination distance, and seasonal ambient temperatures to calculate optimal pack quantity.
How do I prevent products from freezing when using ice packs?
Direct contact between products and frozen gel packs can cause freezing damage. Best practices include placing packs in secondary barrier materials (kraft paper, bubble wrap, or foam inserts) to create insulation between the gel and temperature-sensitive items. Maintain minimum 1–2 inch separation for most products. Ensure proper insulation thickness in your shipping container—typically 2–3 inches of foam board or expanded polystyrene. For delicate biologics, consider phase-change materials or gel pack wrapping solutions that moderate temperature fluctuation more gradually.
What is the difference between reusable gel packs and disposable ice packs?
Ice-Brix™ packs are reusable gel cold packs designed for extended operational life—typically 100+ freeze-thaw cycles when properly maintained. This contrasts with single-use ice packs or dry ice alternatives that cannot be refrozen and regenerated. Reusable gel packs deliver superior total cost of ownership and reduce packaging waste in high-volume operations. They maintain consistent performance across repeated use, whereas ice or phase-change materials may degrade. For permanent cold chain infrastructure, gel packs integrate seamlessly with your freezer management systems.
