Scope

Scope: This document specifies the evaluation principles and methods, evaluation requirements, and preparation methods for life cycle assessment reports of fully biodegradable green design products for agricultural mulch films. This document applies to agricultural mulch films made from fully biodegradable materials, such as aliphatic polyesters, aliphatic-aromatic copolyesters, carbon dioxide-epoxy compound copolymers, and other biodegradable polymers, with one or more resins as the main components. It allows the addition of appropriate proportions of biodegradable natural polymers such as starch, cellulose, hemicellulose, and lignin, as well as other environmentally harmless inorganic fillers and functional additives in the formulation, and is produced by processes such as blow molding or cast film extrusion. This document does not apply to plastic agricultural mulch films containing non-biodegradable polymer materials such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), and polyethylene terephthalate (PET).
