Description
Ice-Brix™ Cold Packs are non-toxic, reusable thermal gel packs designed to maintain precise temperature control during the shipment of temperature-sensitive products. These 3-ounce cold packs are an essential component of any cold chain logistics operation, pharmaceutical distribution network, or perishable goods shipping program.
Each pack measures 5″L x 2-3/4″W x 2-3/4″H and arrives in a convenient 96-pack configuration, making them ideal for high-volume shipping operations. The blue and white exterior design allows for quick visual identification of pack status—blue indicates frozen/ready-to-use condition, while white shows thawed status. These packs are manufactured from food-grade gel material that remains non-hazardous for shipping purposes, eliminating the need for special handling documentation or hazmat labeling. The compact 3-ounce weight provides optimal temperature retention without adding excessive dimensional weight to shipments, which helps control parcel carrier surcharges. Ice-Brix™ packs freeze solid at standard freezer temperatures (32°F/0°C or below) and maintain consistent cooling performance for 24-48 hours depending on ambient conditions, insulation quality, and shipment contents. The durable polyethylene construction withstands repeated freeze-thaw cycles, delivering 50+ reuse cycles per pack before replacement becomes necessary—a significant cost advantage over single-use alternatives.
Temperature-controlled shipping professionals across multiple industries depend on Ice-Brix™ Cold Packs to protect product integrity. Pharmaceutical distributors and compounding pharmacies use these packs to maintain required cold chain compliance during medication shipments. Laboratory suppliers and diagnostic testing facilities rely on them to preserve specimen viability and maintain FDA temperature excursion requirements. Perishable food distributors, specialty seafood shippers, and meal-kit delivery services incorporate these packs into insulated packaging systems to prevent bacterial growth and spoilage. Vaccine distribution networks and medical device manufacturers depend on reliable thermal management solutions to meet GDP (Good Distribution Practice) guidelines. Veterinary pharmaceutical suppliers, biological research facilities, and cosmetic companies requiring temperature-controlled logistics also represent significant user segments.
When evaluating reusable cold pack options for your shipping operation, several critical factors warrant consideration. First, assess your required temperature maintenance window—how long must products remain within specification? Ice-Brix™’s 24-48 hour performance suits most standard parcel shipments but may require additional insulation layers for extended transit times. Second, evaluate pack dimensions and weight relative to your typical shipment size; these 3-ounce packs fit efficiently into insulated mailers and foam-lined shipping boxes without consuming excessive interior space. Third, consider regulatory compliance requirements specific to your industry—pharmaceutical, vaccine, and food shipments demand documented temperature monitoring protocols that integrate seamlessly with your existing cold pack infrastructure. Fourth, calculate total cost-of-ownership by comparing purchase price against expected reuse cycles and replacement frequency. Fifth, verify compatibility with your existing shipping insulation materials and thermal packaging systems. Finally, confirm that your chosen packs deliver consistent freezing point depression and resist thermal degradation across multiple reuse cycles.
What size insulated box should I use with Ice-Brix™ Cold Packs?
Pack selection depends on your shipment weight and required temperature retention duration. A single 3-ounce Ice-Brix™ pack effectively cools 1-2 pounds of product in a standard 6″ x 6″ x 6″ insulated mailer for up to 24 hours. Larger boxes or longer transit times typically require 2-4 packs per shipment, positioned strategically around contents. We recommend conducting thermal testing with your specific insulation materials, ambient temperatures, and product types to determine optimal pack quantities.
How do I maintain Ice-Brix™ Cold Packs for maximum reuse cycles?
Proper maintenance extends pack lifespan significantly. After each use, rinse packs with clean water and air-dry completely before returning to inventory—moisture promotes mold and reduces thermal performance consistency. Store packs in a clean, dry environment away from direct sunlight. Inspect regularly for punctures, leaks, or gel crystallization before each shipment cycle. Freeze packs solid at 32°F (0°C) or below for minimum 4 hours before use. Avoid exposing packs to temperatures exceeding 100°F, as this accelerates polymer degradation.
