    摘要： 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.

    摘要： A molding material having superior buffering character, moldability and dimensional stability obtained by incorporating a copolymer composed predominantly of polyethylene or ethylene with an inorganic filler blend comprising sand with an average particle size of 100 to 500 microns and calcium sulfite, and foaming the resulting composition. A molded product having a lustrous and beautiful superficial coating can be obtained by pressing the aforementioned foamed body while it is still hot against a smooth cool solid surface and cooling the foamed body down to a temperature below its softening point. Further, the aforementioned molding material is useful for packings, mattresses and lightweight construction materials.
