FOAMABLE BRANCHED POLYPROPYLENE COMPOSITIONS AND FOAMED PRODUCTS PRODUCED THEREFROM

Foamable compositions having a branched polypropylene copolymer having a g.sub.vis value of about 0.93 or less, and a foaming agent blended with the branched polypropylene copolymer. The branched polypropylene copolymer comprises a polymerized reaction product of propylene and an ,-diene having five or more carbon atoms. Foamed products may comprise the foamable compositions converted to a foamed form. The g.sub.vis value of the branched polypropylene copolymer may be about 0.8 or less in some cases.

The present invention relates to a method of forming at least one compressed region in a solid cellulose foam, said method comprising the step of: a) Providing a solid cellulose foam; b) Providing at least one cutting line of a predetermined depth of cut into at least one surface of said solid cellulose foam, whereby the at last one cutting line defining at least one pattern on said at least one surface; and c) Pressing at least one pressing tool into said at leas one pattern of said at least one surface of said cellulose foam thereby forming at le st one compressed region. The invention further relates to a solid cellulose foam product formed by the method.
