The future of thermal packaging
Chilltainers are a revolutionary patented process that laminates metallised polyester to corrugated cardboard.

Chilltainers are the ideal replacement for Polystyrene/EPS – recyclable, durable, space efficient, affordable and sustainable.

Chilltainers are superior to Polystyrene/EPS.
Practically, environmentally and economically.
How do Chilltainers work?
What are Chilltainers?
Specialised ‘cool’ thermal packaging and boxes that replace polystyrene,
with increased strength, less bulk and are recyclable.
What are Chilltainers made of?
Strong, specifically developed corrugated cardboard with a reflective
impermeable metallised polyester laminate coating.
How do Chilltainers work?
The corrugated board provides airflow and a conductive layer of packaging,
while the metallised polyester laminate reflects heat away and maintains
coolness inside the package for longer.
Chilltainers are the ideal replacement for polystyrene
being recyclable, durable, space efficient,
affordable and sustainable.

Technical evaluations prove performance.
Independent and customer testing over many years and different environments in
Norway, USA, Australia, Chile and New Zealand has demonstrated Chilltainers thermal
performance equivalent to polystyrene/EPS.
Successful salmon shipments by truck in Norway
Chilltainers recently completed successful shipments by truck from Norway to Poland over 63 hours for a major Salmon producer. The charts below show the range of temperature and humidity from the Xsense data loggers used in various pallet locations across 10 Chilltainers and 5 poly/EPS boxes. The salmon fillets and HOG fish were 0.5-1.0 deg. C at packing at 2-4pm on 23 June, and remained at this temperature until unpacking around 9am 26 June.

There was no variation between the Chilltainers and the polystyrene/EPS whether packed with ice or gel packs. The Chilltainers were in excellent condition. In a similar trial with salmon fillets and HOG from Vancouver Island to Los Angeles by truck over 60 hours the fish was packed 0.0 to 0.5 deg. C, arriving in the same temp range, with the coolants in excellent condition.
Thermal performance of a Chilltainer of salmon airfreighted from New Zealand to Australia
Below is the printout of a datalogger that was inserted along the backbone of a salmon transported in a Chilltainer from packoff in Nelson, New Zealand, to a customer in Brisbane, Australia. Clearly evident is the immediate drop in temperature at 9pm followed by 64 hours sitting at 0-4 degC.
Shipment comparisons between Chilltainers and Polystyrene/EPS
Chilltainers have been recorded in long truck and air shipments in Europe, US, Chile-Brazil, Australia, and NZ. Although the conditions vary daily through these varied supply chains the Chilltainers have measured up almost identically to polystyrene/EPS on each occasion, proving to be the ‘future of perishable packaging’.
"After reviewing the data on the conventional polybin and the
Chilltainers box, the change in the temperature profile
of these boxes follow an identical pattern, and the Chilltainers box
performed very well and is a suitable alternative to the conventional
polybin for the export of chilled and live product."
