The ABA three-layer co-extrusion blown film unit utilizes a dual extruder paired with a three-layer co-extrusion die to produce an A-B-A sandwich structure film in a single step, representing an upgraded replacement for single-layer blown film equipment. The equipment is compatible with high and low-pressure PE raw materials and can produce various plastic films, including packaging bag films, industrial inner lining films, and daily-use packaging films. Core differentiating advantages: The inner and outer layers of the film use brand-new raw materials, ensuring excellent gloss, tensile strength, printing, and heat-sealing effects; the middle core layer can be supplemented with recycled materials and fillers, effectively reducing raw material input without affecting finished product quality. The three-layer structure results in more uniform film thickness, stronger toughness, and lower film breakage losses during production. The equipment supports switching to AAA homogenization production mode, flexibly responding to different order requirements. Widely applicable to various packaging processing plants, it can meet the production needs of daily-use packaging, product liners, and plastic packaging bags, helping film companies balance product quality, continuously reduce production costs, and enhance market competitiveness.
