The function of disposable containers is to preserve the food with some properties and in a controlled environment for a limited period of time, but when they are opened, these properties are altered and lost. Both the materials and the thicknesses with which they are manufactured do not support the professional requirements that the pieces are submitted to. Although the material used is suitable for contact with food, compliance with the restrictions established by the different directives on food contact must be guaranteed. Once the main use of the product (container or receptacle) has ended, and when it is used for other uses, it can give off additives and substances that migrate to the food, as the article is being used incorrectly. The minimal part thicknesses used in these containers mean that they break more easily due to impact or thermal shock, when they pass from very cold to very hot temperatures in a very short period of time. The pieces that break off can affect the food quality of the product, running the risk of being swallowed with the food. (Contamination by physical agents). In the wash, they do not support some chemical solvents or the temperatures of wash cycles.
