Selecting a gel pack freeze temperature is not intuitive — a colder pack is not always better, but the temperature differential between refrigerant and ambient drives cold chain duration in ways most operators underestimate.
Most buyers treat gel packs as interchangeable commodities. They are not. The chemistry of the polymer gel inside determines freeze temperature, thermal capacity, safety profile and longevity. Here is what the engineering data shows.
Dry ice packs in a commercial cold chain setting carry specific safety obligations under Safe Work Australia and state WHS regulations. This guide covers ventilation, PPE, storage limits and disposal requirements.
Global CO₂ supply constraints have created dry ice availability risks that Australian cold chain operators cannot ignore. This engineering guide covers supply chain risk, strategic stock management and refrigerant alternatives.
The geometry of a dry ice pack’s internal cell structure determines how efficiently it transfers cold to your payload. Here’s the engineering analysis behind 2-ply construction and cell configuration sizing.
Temperature data loggers are the black box of cold chain logistics — recording what actually happened to your shipment. Here is how to select, deploy and interpret them for TGA GDP compliance and operational improvement.
