None of our keeeper products are harmful to health – either for adults or for children. They are free of Bisphenol A (abbreviation: BPA), and do not contain heavy metals, plasticisers or other potentially harmful substances. Products for use with food, in particular, are subject to extensive and stringent requirements, which we fulfil.
All keeeper products are heat and temperature-resistant. You can find exact information on the maximum and minimum temperature on the products themselves or with the respective product on our website.
For our keeeper products, we use material in accordance with the physical requirements. You can use a keeeper product in the microwave if its use is indicated as safe. Just one example: our storage container fredo fresh can be used in the microwave. An important keeeper tip: in order to avoid overheating, the temperature of the food should not exceed 100 °C! It is best to heat the meal for 3 minutes at max. 400 Watts. Then stir it and heat again if necessary. Please also ensure that the lid is not closed, but rather merely placed loosely onto the container.
Discolourations on keeeper products, caused by strongly-coloured food such as carrots or red beets, generally disappear in the dishwasher. However, if fat containing food (e.g. goulash or tomato sauce) is overheated in the microwave, then permanent discolouration may result. In order to avoid overheating, the temperature of the food should not exceed 100 °C.
If the keeeper product is labelled with the appropriate symbol, you are welcome to put it into the dishwasher. This symbol can generally be found on the bottom of the product. We recommend that you place our products on the upper shelf of the dishwasher.
keeeper products do not generally take on odours. In exceptional cases, slight odours may persist after use. In such cases, we recommend that you leave the keeeper jar open for several hours in a freezer compartment. Caution: Do not drop the keeeper jar when frozen as it may break!
