Some merchandise can be stored indefinitely without being affected by temperature, but for some products this is not the case. These perishable products must be kept in certain temperature ranges in order to maintain their qualities and, in many cases, so that they are not harmful to humans. We are talking about a large number of foodstuffs, various medicines, vaccines and many other products (flowers, technology, chemicals, etc.).
It is crucial to follow the guidelines of specific technical documentation to ensure that the cold chain is maintained and that safe handling procedures are followed in each case in order to protect the consumers. But it is essential to be aware of the different ranges that are used in the temperature-controlled transport industry.
What are the main temperature ranges?
We would like to point out that each product has its own requirements, but it is possible to distinguish six main “families” when it comes to temperature ranges:
- Hot: although hot products are often not included into temperature-controlled transport statistics they certainly take an important place in isothermal transport: above 57o
- Ambient: some products should always be kept in a “medium” temperature range, which is usually between 15-25oC.
- Fresh not refrigerated: this category includes products that do not require additional refrigeration for their preservation but must be kept in a suitable range (between 8-15C o) to maintain their properties.
- Refrigerated: these products require low temperatures, but above the freezing point; between 2-8oC.
- Frozen: in these cases the products must be kept in frozen state, until certain micro-organisms are completely neutralised: -18-0o
- Deep-frozen: these are products that require thermal stabilisation at deep cold temperatures, from -25 oC downwards.
Caution, these ranges are indicative. Each product has its own requirements (for example, there may be a food that can be preserved fresh for 24 hours, but requires refrigeration at 4 degrees or less to be preserved for three days).
Our temperature ranges
At Tempack, as specialists in temperature-controlled packaging, we can produce passive cooling isothermal packaging (shippers and cooling elements) for any possible scenario, here are four examples of some specific temperature ranges we deal with:
- Temperature above 57 o That is, the one that allows a product cooked above the legally established minimum cooking temperature to be maintained. This is the range required for transport of all ready-to-eat meals.
- Temperature range between 10-18o This is the required temperature range for products that do not require active cooling, but which do not tolerate heat well: this is the case for chocolate, wax or many fruits and vegetables.
- Temperature range between 1-5o It is recommended for some products such as fresh meat or fish, dairy products and many thermolabile medicines to be stored & transported in a lower temperature than standard 2-8oC in order to be well preserved.
- Temperature below -12o Frozen products like raw or processed foods, ice cream, or some specific medicines must not exceed this temperature under any circumstances.
An isothermal packaging which will suit your needs
As you can see, each product, each situation and each company has its own requirements and peculiarities in terms of cold chain. Let us help you to find a matching insulated packaging solution for you.
