Dimensions (HxWxD)
Container dimensions in height, width and depth; for round containers (see "Shape") after the height, only one size is indicated — the diameter. Information about the dimensions allows you to evaluate the proportions of the container (in models of the same volume, they may be different) and determine what specific space it will need.
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).
Country of origin
Country of origin of the brand under which food containers are marketed. Usually, it is indicated by the "homeland" of the manufacturing company or by the location of its headquarters.
There are many stereotypes associated with the “nationality” of brands and products, but most of them have no basis nowadays. First, the actual place of production is often different from the brand's country of origin. Secondly, the quality of the goods depends not so much on geography, but on the policy of a particular company and how carefully this very quality is controlled in it. Therefore, you should pay attention to the country of origin of the brand only if you fundamentally want or (do not want) to support a manufacturer from a certain state. Quality is best judged by the reputation of a particular brand and the general price category.
