Abstract: Thermoplastic rubber containing minor amounts of amorphous polypropylene is extruded into films. The films retain characteristic elastomeric properties of pure rubber, but are significantly more processable owing to the presence of the amorphous polypropylene.

Abstract: A moisturizing mat, and process for making it, are disclosed. The moisturizing mat is suitable for use as a base to promote trickle watering of plants in greenhouses. The mat comprises a wood pulp/fabric layer having an impervious plastic film backing layer. The moisturizing mat is produced by a process including the steps of (a) depositing wood pulp on a first fibrous layer, (b) placing a second fibrous layer on top of the wood pulp, (c) bonding the product of step (b), and (d) bonding an impervious plastic film to one face of the product of step (c).
