1000L Five-Layer Co-Extrusion Blow Molding Machine

The 1000L five-layer co-extrusion blow molding machine is a classic high-end multi-layer barrier molding device, adopting five-extruder precise co-extrusion technology. It forms a standard HDPE/Adhesive/Barrier/Adhesive/Regrind five-layer composite structure, which is the mainstream equipment for high-standard anti-corrosion and barrier container production in the industry. Targeting high-end scenarios such as high-purity food materials, strong corrosive chemicals and pharmaceutical intermediates, this equipment achieves ultra-high barrier performance while realizing efficient cost reduction through layered material matching.​

The five-layer structural design realizes functional partitioning and cost optimization to the greatest extent. The outer HDPE layer provides mechanical strength and weather resistance; the double adhesive layers ensure firm lamination between layers and prevent peeling; the middle core barrier layer uses high-performance EVOH or PA material to block oxygen, moisture and chemical solvent penetration; the innermost regrind recycling layer adopts qualified recycled materials, which can reduce raw material cost by 15%-20% without affecting product safety and barrier performance. Compared with three and four-layer equipment, its barrier precision is higher, material utilization rate is better, and product comprehensive performance reaches industrial high standards.​

The equipment is equipped with a professional five-layer stacked die head and independent closed-loop servo control system, with ultra-high layer thickness control accuracy and stable layer ratio. The specially designed barrier screw ensures sufficient plasticization of high-performance barrier resins and avoids material aging and deterioration. The full-automatic intelligent production system realizes one-key molding, with low defective rate and excellent batch consistency.​
​
This five-layer equipment is widely used in food-grade storage tanks, high-corrosion chemical ton barrels and pharmaceutical packaging containers. It has become the benchmark model in the high-end multi-layer blow molding industry due to its excellent barrier performance, reasonable cost control and stable product quality, and is favored by high-standard manufacturing enterprises at home and abroad.
