Abstract
A small amount of an absorber mixture comprising activated aluminum oxide and potassium permanganate deodorizes the space within closed, gastight packs, in particular the space within packs of the type in which objects or materials which comprise polyacetal or otherwise release formaldehyde are present. Deodorization here is the removal (i.e. elimination or absorption) of volatile constituents emerging from plastic moldings or from plastic materials, in particular cleavage products, such as formaldehyde. The process is particularly suitable for the packaging of moldings or of assemblies which are to be used in the medical sector, in the food and drink sector or in any other sector affecting health.
