Cooling elements: the unmissable link in thermal packaging

Coolpack’s products are an indispensable link when it comes to thermal packaging, also known as thermal packaging. Binnen de gevalideerde thermal packaging verpakkingsoplossing worden met name koelelementen gebruikt. Met de juiste buitenverpakking kan voor een lange periode een zeer stabiele temperatuur worden aangehouden, namelijk tot een periode van 120 uur.

Om dit te realiseren kunnen de koelelementen worden gevuld met Phase Change Material (PCM). Door de hoge kwaliteit van deze vulling is het mogelijk stabiele temperaturen te behalen binnen een temperatuurrange van -65 tot +42 graden.

Indien de voorkeur uitgaat naar een flexibeler koelmiddel kunnen onze diepgevroren gelpacks ook worden ingezet om de te verzenden producten op temperatuur te houden. The gel packs can also be filled with PCM to maintain very stable temperatures for a long period.
