We develop your individual passive cooling packaging. Through exact thermal calculation we determine the required wall thickness of the thermo box, the cooling quantities and the positioning of the cooling elements, foam bricks or gel packs. The thermal calculation takes into account the temperature limits of the product to be maintained, the required transport time and the external temperature profile. Customer-specific or standards such as ISTA or AFNOR are used as temperature profiles. The thermal and constructive engineering of Schaumaplast shortens the development times of new thermo boxes and the configuration of existing thermo boxes. The performance of the newly developed thermo box equipped with cooling elements is finally verified in a climate chamber test. In this process Schaumaplast also cooperates with ISTA-certified laboratories. The customer thus receives written documentation on the performance of his new thermal packaging.
