Abstract

A polymeric composition to be used in producing foam.
The polymeric composition comprises a linear low density polyethylene and a resiliency modifier resin. The linear low density polyethylene is in the amount of from about 1 to about 90 weight percent of the polymeric composition.
The linear low density polyethylene has a z-average molecular weight, Mz, greater than about 700,000. The resiliency modifier resin is in the amount of from 10 to about 99 weight percent of the polymeric composition. The resiliency modifier resin can be made of a low density polyethylene. Reclaimed material may comprise a portion of the linear low density polyethylene.
