Insulation materials

Insulation materials for chilled transport: from a single box to a complete pallet

Insulation material forms the passive barrier that protects your product against heat, cold and temperature swings in transit. It does not cool by itself, but slows heat transfer from outside, so your shipment stays within the right temperature window for longer. Combined with cooling elements, this gives a complete, reliable cold chain, whether you send one box or a whole pallet. As a manufacturer with our own production since 1972, we supply the full range from our own stock.

Which insulation material do you need?

The right choice depends mainly on the size of your shipment and how you pack. Below are the four main uses, each with the matching material.

Pallets and roll containers → thermal covers

If you ship whole pallets or roll containers, choose thermal covers, reusable insulating blankets that enclose the whole pallet or ULD. Widely used in air freight and chilled road transport, in standard sizes for EURO and US pallets and for ULDs such as LD3, LD6 and PMC.

Loose boxes → cooling bags or insulation foil

If you want to insulate loose boxes, use a cooling bag or insulated bag as an inner lining in the box, or wrap the box in insulation foil on a roll, which you cut to size easily. Both are flexible, light and compact to store.

Small, flat shipments → cooling envelopes

If you send small, flat products by post or courier, a cooling envelope is light, affordable and often fits through the letterbox, suited to sushi, cheese, charcuterie or pharma samples.

Under the load → insulated base sheet

The base is often the weakest spot in the insulation. Put an insulated base sheet under the load to hold the cold in from below, and together with a thermal cover you close off the whole pallet as a complete insulation cocoon.

How does insulation material work?

Our insulation materials work on two principles at once. A reflective layer (aluminium or metalized PET) bounces radiant heat back, while a buffer of still air, in bubble film, foam or a honeycomb structure, slows heat transfer. Together they keep the temperature inside your packaging stable for longer.

Important: insulation material does not cool by itself. It extends the effect of your cooling. So always combine it with gel packs or cooling elements, put them on top of the product (cold air sinks) and pack as tightly as you can. The less empty space, the better the result.

What is insulation material used for?

• Food and fresh e-commerce. Getting meat, fish, dairy and meal boxes to the customer chilled, even with delayed delivery.
• Pharma and air freight. Medicines, vaccines and biological samples within a strict temperature range, in line with GDP and IATA.
• Fruit, vegetables and flowers. Protecting vegetables, fruit and cut flowers against temperature peaks and condensation during handling and export.
• Road transport and last mile. A passive solution when a refrigerated vehicle is not available or too costly.
