TPS Insulated Box Liners

Our custom-sized insulated box liners are a space-saving and cost effective way to deliver chilled & fresh goods. They are ideal for transportation of food, drinks, pharmaceuticals and other temperature sensitive products. Ensure your customers receive their orders cold, fresh and profesionally packaged without using bulky Polystyrene.

Insulated Box Liners

We use ThermaPack insulation in our box liners which is manufactured from true aluminium foil & incorporates thermo bubble technology to create a high performance temperature control radiant barrier whilst taking up minimal space. Our insulated box liners perform better than expanded polystyrene (EPS), maintaining the correct content temperature for longer. We offer two material options: ThermaPack Single and our best selling, high performance ThermaPack Ultra Double. Please see the chart below for a comparison.
