The multi-layer blow molding machine for pesticide bottles is a specialized equipment that excels in manufacturing multi-layered (1-6 layers) and high-barrier pesticide bottles, chemical containers, and plastic drums. By utilizing advanced multi-layer co-extrusion technology, it incorporates high-barrier materials (such as EVOH) within the layers of the plastic bottles, significantly enhancing their barrier properties against gas, liquid, and odor permeation, ensuring the stability and safety of the packaged contents.
