Jargon Guide

Struggling with cold chain copy or sample transport terminology, then this guide is for you. Read below to discover the meaning of some popular sector jargon and terminology.

Temperature Control Terminology

Conditioning

The preparation process for PCM materials is required in a specific phase before use within a system.

Cool pack

Typically, a semi-rigid sealed pouch of material, often water-based and used to maintain payload temperatures in temperature-controlled packaging solutions.

EPS

Expanded Polystyrene, molded or sheet insulation material.

Passive

In the temperature-controlled packaging sector, “Passive” packaging refers to solutions that operate without an electrical supply providing heating or cooling.

Instead, passive solutions use insulation and thermal media to achieve temperature control.

Phase Change Material/PCM

A material that is intended to change physical phase (melt/freeze/sublime) at a specific temperature, thereby providing thermal stability.

Temperature excursion/deviation

A situation where the payload temperature falls outside the desired temperature range.

Temperature Profile

Temperature profiles are comprised of temperature-based data points that can be cycled through when testing temperature-controlled packaging.

VIP

Vacuum Insulation Panel, high-performance sheet insulation material.
