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).
