Temperature-Controlled Packaging Insulation: An Overview

There are many different types of insulation that can be used in temperature- controlled packaging, including:

  • Expanded Polystyrene (EPS)
  • Extruded Low Density Polyethylene (LDPE)
  • Extruded Polystyrene (XPS)
  • Vacuum Insulation Panels (VIP)

To help you understand the differences between types of insulation, here is a basic breakdown:

Expanded Polystyrene (EPS)

This material can be molded into specific shapes and is relatively inexpensive, with a high capacity for insulation. It can be damaged during shipping, which can cause problems with reuse.

Extruded Low Density Polyethylene (LDPE)

Low density polyethylene (LDPE) silver insulation foam packaging is made from polypropylene – one of the easiest and most commonly recycled plastics in the world. This durable material is cut into panels that fit together to control temperature.

Extruded Polystyrene (XPS)

Extruded polystyrene foam (XPS) consists of closed cells, offers improved surface roughness and higher stiffness and reduced thermal conductivity. It is very easy to cut and shape, and it is resistant to water. Like the LDPE, XPS is cut into panels that fit together to control temperature.

Vacuum Insulation Panels (VIP)

Vacuum insulated panel (VIP) is a form of thermal insulation consisting of a nearly gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. Their insulation properties are seven times as effective as the expanded polystyrene EPS used in typical shipping systems. They are more expensive than conventional systems but you can end up with a smaller box.
