  • Method of enhancing the quality of produce using an agricultural sheet material
    Patent number: 5295324
    Abstract: A method of enhancing the quality of fruits and vegetables grown on trees and/or on plants by covering a substantial portion of the soil surrounding the plant or tree with a spunbonded nonwoven film-fibril sheet material that has been produced by a flash-spinning process. Preferably, the sheet comprises a plexifilamentary film-fibril sheet fabricated from a polyolefin such as polyethylene or polypropylene. When the spunbonded nonwoven film-fibril sheet material is used in this manner, it unexpectedly enhances fruit quality by providing excellent water resistance, moisture vapor permeability and air permeability.
