| 摘要 |
A mulch film for enhancing agricultural growth is disclosed. A layer of aluminum is vacuum metallized on a surface of a polymeric film substrate. The substrate is preferably black or white. The substrate is preferably a monolayer or a coextruded layer. In one embodiment, the polymeric film substrate is formed by coextrusion of a high density and a low density polyurethane. The substrate preferably has a thickness of at least 1.0 mil. There are also disclosed embodiments of the invention where stripes or portions of the substrate are intentionally shielded from having a layer of aluminum deposited thereon in various configurations. In yet another embodiment, substantially all of the surface of the substrate is vacuum metallized with a layer of aluminum. In yet another embodiment, the substrate is a transparent polymeric film having a color. Additionally, there is disclosed a method of forming the embodiments of the invention as described above.
