Weed Suppression System and Method

摘要

A bag constructed of a weed suppression material for packaging a ground cover material. When the bag is in a closed configuration, the bag serves as a container for shipping, handling, and storage of the ground cover material. When the bag is opened and unfolded, and the ground cover material within the bag is spread over the opened and unfolded bag, the bag serves as a layer of weed suppression material on top of underlying soil and beneath the ground cover. The weed suppression material is a porous, water permeable, biodegradable film made from mixtures of a polybutylene succinate (PBS) resin, a polyhydroxy alkanoate (PHA) resin, a polylactic acid (PLA) resin, a polybutylene adipate terephthalate (PBAT) resin, a polybutylene adipate succinate (PBAS) resin, or a thermoplastic starch (TPS).

主权项

1. A weed suppression system for a planting bed having soil, the system comprising:
a. a bag comprising:
i. a front panel formed from a sheet of weed suppression material and having a front panel area;ii. a back panel formed from a sheet of weed suppression material and having a back panel area, wherein the front panel and the back panel are joined at their end edges and their side edges to form a completely enclosed bag, wherein at least one end edge or one side edge constitutes a fold line, and wherein the bag has a bag area comprising the front panel area and the back panel area; andiii. indicia along which the bag is opened so that the bag unfolds along the fold line into a single flat sheet of weed suppression material including the entire bag area; andiv. wherein the weed suppression material is in contact with existing soil and comprises a porous, water permeable, biodegradable film formed from a polybutylene succinate (PBS) resin; and b. a sufficient amount of ground cover contained within the bag to cover the bag area when the bag is unfolded and laid flat on the soil.
