Containers per set
The total number of individual containers supplied in the set (see "Type").
The more containers, the greater their diversity and the wider the choice of the user. At the same time, the variety can be not only in terms of volume, but also in proportions, and even in shape: for example, in sets of 5 items or more, there can be “high” and “low” containers, square containers can be combined with round ones, etc. .P.
It is worth remembering that “a lot” does not always mean “good”: an extensive set may require a lot of space, and it will cost accordingly. Therefore, when choosing, it is worth considering the real needs.
Min. temperature
The minimum temperature that a container can safely tolerate. Almost all modern food containers normally tolerate positive temperatures. So you should pay attention to this parameter only if the container is planned to be used for
deep freezing, or used in harsh winter conditions. However, the minimum temperature in domestic freezers is rarely below -24 °C, while for food containers it is -40 °C as a standard. On the other hand, it is worth noting that many models have no mention of a minimum temperature at all; it is necessary to use such products in the cold, taking into account the materials from which they are made (see above), and if possible, refrain from doing so altogether.
Max. temperature
The maximum temperature that the container can safely endure. Note that overheating the container can lead not only to its damage, but, in some cases, also to the release of harmful substances. Therefore, in no case should the claimed temperature be exceeded — even if the container remains intact, this does not mean that everything is fine.
The most delicate modern food containers have a maximum limit of 35 – 40 °C — this allows them to be used only for unheated food. Values of 70 °C are already found even among models compatible with microwave ovens, although for maximum guarantee it is desirable that the allowable temperature be at least 100 °C. And the most heat-resistant products (usually heat-resistant glass) can withstand temperatures up to 300 – 400 °C and can even be used for baking in the oven (although this heat resistance usually does not apply to lids, and they must be removed).
