摘要

The cover comprises a film (102) including a polyolefin fabric (202), and an aisle (104) having a base (206) fixed to the film, where the base is made of polyolefin foam. A reinforcing membrane (208) is attached to the base. A passage strip is fixed to the reinforcing membrane. The film further comprises polyolefin foam attached to the polyolefin fabric. The reinforcing membrane is a grid. The foams are formed with closed cells.
