Description
Ice-Brix™ Cold Packs are premium reusable thermal gel packs designed to maintain cold chain integrity during shipping and storage of temperature-sensitive products. These 24 oz. cooling elements are the industry standard for pharmaceutical, food, beverage, and medical device logistics requiring reliable, leak-proof refrigeration.
Each Ice-Brix™ Cold Pack measures 8″ L x 6″ W x 1-1/4″ H and features a durable white and blue exterior that clearly identifies the pack’s purpose in any shipping environment. The leak-proof construction prevents gel migration and contamination, making these packs ideal for compliance-heavy industries where product integrity and regulatory adherence are non-negotiable. With a 24 oz. capacity, each pack delivers sustained cooling performance for 8–12 hours depending on ambient temperature and insulation configuration. The flexible gel formula freezes solid at 32°F (0°C) and can be refrozen indefinitely without degradation, making Ice-Brix™ packs a cost-effective alternative to disposable cooling media. This bulk 12-pack offering ensures you maintain adequate inventory for high-volume shipping operations without frequent reordering. The flat, rectangular design maximizes space efficiency in insulated shipping boxes and coolers, reducing wasted airspace and dimensional weight charges.
Ice-Brix™ Cold Packs serve pharmaceutical distributors, clinical laboratories, specialty food shippers, blood banks, vaccine logistics providers, and cosmetic manufacturers who depend on temperature-controlled transportation. Common applications include shipping biologics, injectable medications, temperature-sensitive diagnostics, perishable foods, and premium beverages across domestic and international routes. Cold chain logistics professionals rely on these packs for FDA-regulated shipments, IATA compliance for hazardous materials, and UPS/FedEx temperature monitoring programs. E-commerce fulfillment centers use Ice-Brix™ packs for meal kit delivery, seafood shipping, and frozen product distribution. Medical device manufacturers incorporate them into sterile shipping protocols. The reusable nature makes them particularly valuable for reverse logistics and recycling programs, reducing per-shipment costs for organizations shipping thousands of units monthly.
When selecting cold packs for your cold chain operation, consider three critical factors: thermal performance duration (how long the pack maintains effective cooling), leak-proof integrity (whether the pack can withstand punctures, pressure, and temperature fluctuations without compromising surrounding products), and pack dimensions (whether the size optimizes your insulated box configuration and weight limitations). Verify that your chosen cold packs meet industry standards for your specific application—pharmaceutical shipments may require FDA or USP compliance, while food shipping demands USDA or FSMA alignment. Evaluate whether you need single-use or reusable packs based on your shipping frequency and sustainability goals. Confirm that your cold pack supplier provides technical data sheets detailing thermal retention curves, gel composition safety information, and storage instructions. For high-volume operations, calculate cost-per-shipment by dividing total pack investment by expected reuse cycles, as premium leak-proof construction often yields better long-term ROI than cheaper alternatives prone to failure and product loss.
What size cold pack do I need for my shipping application?
The 24 oz. Ice-Brix™ Cold Pack is the most versatile size for standard corrugated insulated shipping boxes (typically 12″ x 10″ x 6″ or similar dimensions). For small parcels or envelope-style coolers, consider smaller packs; for large temperature-controlled pallets or extended transit times exceeding 24 hours, use multiple 24 oz. packs or combine them with dry ice or phase-change materials. Your supplier can provide cooling duration charts that correlate pack size, quantity, insulation thickness, and ambient temperature to help you select the right configuration for your specific route and product requirements.
How do I properly freeze and maintain Ice-Brix™ Cold Packs for repeated use?
Place Ice-Brix™ packs in a standard freezer at 0°F (-18°C) for a minimum of 4 hours before shipping, ideally overnight for maximum thermal capacity. After use, rinse the exterior with mild soap and water, inspect for leaks or damage, allow to air-dry completely, and return to frozen storage. The gel formula is non-toxic but should not be ingested; if a leak occurs, avoid direct skin contact and wash immediately. Packs can be refrozen indefinitely without performance loss, making them suitable for hundreds of reuse cycles over several years when properly maintained.
What is the difference between Ice-Brix™ Cold Packs and dry ice or phase-change materials?
Ice-Brix™ gel packs are reusable, non-hazardous, and produce no sublimation or vapor emissions, making them IATA-compliant and safe for all shipping methods. Dry ice requires hazardous materials certification, special packaging, and handling protocols, though it maintains lower temperatures longer. Phase-change materials (PCM) offer narrower temperature ranges
