The flexible and economic solution for the dispatch of temperature-sensitive food products. The COOLMAILER ensures customers receive products such as chocolate, fish and fresh meat always in a cooled condition.

The COOLMAILER is available in different sizes and can be combined with cooling elements to provide a flexible solution for the dispatch of sensitive products under cooled conditions. The cold chain can be guaranteed for more than 24 hours using the COOLMAILER along with the necessary number of Coolpacks. The thermal coverings are available in different sizes and have been specially developed for parcel dispatch. They offer optimal utilisation of space and enable dispatch in a single package of both dry goods and goods requiring cooling. An adhesive flap provides easy handling and, when sealed, prevents unwanted air leakages.

The following standard sizes are always on stock (basic dimensions, 4cm for sealing flap in brackets):

  • 25x18 (+5) cm
  • 40x40 (+5) cm 
  • 60x40 (+5) cm (minimum order quantity: 250)
