Sorbatek is available in various formats, sheets, rolls and blocks to meet with your journey time and temperature requirements. The deeper the cell the greater the temperature maintenance in line with surface to volume ratio of each.
The optimal solution will be unique to the product size, weight and insulated outer chosen combined with the initial packing temperature and level of temperature maintenance required for the duration of the delivery journey.
There are many variables to impact performance which the Sorbafreeze team will be happy to discuss in finer detail, just give us a call.
Keep products and all packaging in the freezer until you are ready to pack and seal your products for dispatch. This helps to maintain the overall temperature of your package, ensuring optimal temperature performance whilst in transit.
When packing leave no spaces, fill all voids with paper, bubble wrap or preferably product! Any gaps will allow free air to circulate, allowing the temperature within the insulated unit to increase greatly. The right box size makes all the difference. If the stock range doesn’t suit, please contact us for a better-suited size.
Ensure a lid of ice packs (Sorbatek/Hydratek) cover the top of your goods, chill sinks downwards. Should the volume of goods demand it add layers of ice packs between and below your goods.
Completely seal the box when packed to minimise the impact the external environment may have on the contents of the insulated unit.
The ice packs work within an insulation chamber to initially balance then maintain temperature within the dispatch unit.
To optimise performance you need to start with the packaging, the products and the packing room at the lowest possible temperature, this will then minimise the work required by the ice pack whilst in transit.
When packing your chilled insulated box ensure there are no air gaps between the products or on top when fully packed, ideally fill all with gaps with product or ice packs. Fill any spaces left with void-fill such as paper or bubble-wrap, any gaps will allow free air to circulate and increase the temperature more rapidly than a tightly packed box.
It is important to have the correct size of box to minimise your cost of carriage and your goods securely in place throughout the courier journey. We have a comprehensive range of stock sizes but can also offer bespoke sizing and printing for quantities as low as 350 boxes!
So box chosen and chilled, products all tightly packed, just add the correct ratio of ice (Sorbatek or Hydratek) to the box. Most clients add it on top of the products giving a chill lid effect but others split it between the top, mid, bottom and sides of the package. Chill does tend to sink downwards but in reality the entire insulation chamber will be balanced through-out.
You must seal the insulation liners to create the chill chamber to prevent the chill escaping or external air entry, then seal the outer box and ready for dispatch and temperature safe travel for up to 48 hours.
The temperature will increase by a few degrees initially within the box until the ice creates a balance within the chamber it will then maintain for up to 48 hours.
