Abstract
Plural recesses are formed on the surface of a sheet of a chemically crosslinked foam of a polyolefinic resin containing an inorganic calcium compound, the articles of food to be packaged are placed in the recesses and then the sheet is covered with a physically foamed sheet of a polyolefinic resin containing an inorganic calcium compound. Alternatively, the physically foamed sheet can be shaped to define a recessed support for the food articles and a sheet of foamed polyolefinic resin used as the covering. The polyolefinic resin has 30-60% by weight of an inorganic calcium compound incorporated therein.
