Description
Ice-Brix™ Cold Packs are compact, leak-proof gel-filled cooling units designed to maintain product freshness and integrity during temperature-sensitive shipping and storage. These reusable refrigerant packs are essential for cold chain logistics, pharmaceutical distribution, perishable food transport, and laboratory specimen handling across industries.
Each 6-ounce Ice-Brix™ unit measures 6 inches long by 4 inches wide by 3/4 inch thick, offering an optimal balance of cooling capacity and space efficiency within insulated shipping containers and thermal packaging systems. The leak-proof construction features a durable plastic exterior and sealed gel interior that prevents cross-contamination and product damage from moisture exposure. These cold packs are white and blue in color for easy visibility and inventory management. Each case contains 48 individual packs, providing substantial quantity for high-volume shippers. The non-toxic formulation meets FDA regulations for products that may incidentally contact food items, making them suitable for multi-industry applications. The compact 3/4-inch profile allows strategic layering within shipping boxes without consuming excessive space, maximizing payload efficiency. Ice-Brix™ cold packs maintain optimal cooling performance between 32°F and 59°F ambient temperature ranges and can be frozen repeatedly without degradation, reducing operational costs through extended product lifecycle.
Cold pack users span pharmaceutical distribution centers, clinical laboratories, biotechnology firms, specialty food distributors, meal kit delivery services, vaccine logistics providers, and medical device manufacturers. Temperature-controlled shipping applications include overnight courier services managing perishable biologics, regional blood banks transporting critical medical supplies, frozen food e-commerce operations, and compounding pharmacies shipping temperature-sensitive medications. Environmental compliance departments appreciate the reusable refrigerant pack model, which eliminates single-use plastic waste compared to disposable alternatives. Industries requiring cold chain integrity documentation—including pharmaceutical and food safety sectors—benefit from the consistent, predictable cooling performance that simplifies temperature monitoring protocols.
When selecting gel ice packs for shipping operations, evaluate critical factors including cooling duration (how long the pack maintains target temperatures under specific insulation conditions), gel composition (food-safe versus industrial-grade), puncture resistance and overall durability for repeated freeze-thaw cycles, thermal conductivity ratings, and pack dimensions relative to your shipping container specifications. Consider the total cost-per-use for reusable packs versus disposable options, especially for high-frequency shippers. Verify compatibility with your existing thermal shipping containers, insulated packaging materials, and temperature monitoring equipment. Assess whether your operation requires pre-frozen delivery capabilities or if on-site freezing capacity is available. Review regulatory requirements specific to your industry—pharmaceutical shipments, for example, often require validated cold chain packaging with documented thermal performance data.
What size ice packs do I need for my shipping containers?
Ice pack sizing depends on your insulation quality, ambient temperature conditions, and required cooling duration. The 6-ounce Ice-Brix™ units work effectively for small to medium parcels, typically 4–8 cubic inches of internal shipping space. For larger boxes or extended transit times exceeding 48 hours, use multiple packs or larger units. Calculate total cooling requirement by assessing your thermal mass (product weight and specific heat), ambient conditions during transit, and desired temperature range. Most passive temperature control systems use one 6-ounce pack per 2–3 pounds of product; adjust based on your specific insulated packaging thickness and climate zone.
How do I properly freeze and reuse Ice-Brix™ cold packs?
Place packs in a standard freezer set to 0°F or below for minimum 24 hours before use. The sealed gel design allows unlimited freeze-thaw cycles without leakage or performance degradation. After use, rinse exterior surfaces, allow complete air-drying, then store in a cool location before refreezing. Most operations maintain dedicated freezer space for cold packs on a rotating schedule, ensuring inventory availability. Never attempt to open, puncture, or modify packs, as this compromises the leak-proof integrity and cooling efficacy.
What is the difference between reusable gel packs and disposable ice alternatives?
Reusable gel ice packs like Ice-Brix™ provide superior long-term economics, reduced environmental impact, and consistent thermal performance across multiple shipments. Disposable ice or single-use packs generate higher per-shipment costs and waste accumulation. Gel packs maintain stable temperature profiles longer than loose ice and eliminate melting water contamination. For operations shipping 50+ parcels
