The invention discloses an environment-friendly plastic metalizing decoration process and belongs to the field of plastic decoration. The method comprises the following steps: a, cleaning a molded plastic part; b, coating primer, wherein the plastic part is coated with acrylate UV (ultraviolet) primer and then cured so that the uneven surface of a base material is flattened with the primer; c, coating a film in vacuum, wherein the plastic part is put into a vacuum film coating cavity of vacuum film coating equipment, the vacuum degree of the vacuum film coating cavity is controlled to be between 10<-2> and 10<-3>Pa, and performing vacuum continuous film coating after plasma dust collection; d, coating protective paint, wherein the plastic part is coated with the acrylate UV protective paint which is matched with the UV primer and then cured to form a paint film with a certain hardness; and e, pasting a film on the plastic part, and packaging the plastic part. The environment-friendly plastic metalizing decora
