The HDPE extrusions(polyethylene extruder) die head is usually used in polyethylene film extrusion to produce thicker films or some packaging films with low requirements.
The HDPE Extruder Die Head can produce medium-thickness thin films and film bags. It is mainly through low speed flow and less heat energy to directional stretch forming, so as to obtain the polyethylene extruder die head. The HDPE die head is characterized by low cost and wide applicability in polyethylene blown film extrusion, and can produce some packaging films commonly used in daily life, such as shopping bags, garbage bags, storage bags, etc.

HDPE EXTRUSIONS APPLICATIONS
- Bottles and Containers: HDPE Extrusions is commonly used to produce milk jugs, detergent bottles, and other containers for liquids.
- Pipes and Fittings: HHDPE Extrusions are used for water supply, sewage, gas distribution, and industrial applications due to their durability and resistance to corrosion.
- Irrigation Systems: HDPE Extrusions and tubing are used in irrigation systems for their flexibility and resistance to chemicals.
- Toys: Many children's toys are made from HDPE due to its safety and durability.
- Household Items: Products like cutting boards, storage bins, and laundry baskets are often made from HDPE.
- Furniture: Outdoor furniture, such as chairs and tables, are made from HDPE Extrusions for their weather resistance.
HDPE EXTRUSIONS PROPERTIES
High Strength-to-Weight Ratio: HDPE extrusions are strong and durable, yet lightweight.
Excellent Chemical Resistance: HDPE Extrusions are resistant to a wide range of chemicals, including acids, alkalis, and solvents.
Good Impact Resistance: HDPE extrusions can withstand impacts and shocks without breaking.
Low Water Absorption: HDPE Extrusions have low water absorption properties, making them suitable for outdoor applications.
Good Processability: HDPE is easy to process through extrusion, making it a versatile material for various shapes and sizes.
Excellent Weldability: HDPE can be welded using various techniques, including heat fusion and butt fusion.
KEY CONSIDERATIONS FOR HDPE DIE HEAD
In the process of blowing film, it is very important to choose the right die head, we need to choose the die head from the following aspects:
The die head is selected by the material used.
The thickness of the blown film is different: the thinnest LDPE die head can blow a film of 0.003mm thick, while the thinnest HDPE die head can blow a film of 0.02mm thick.
Product quality is different: the transparency, strength and toughness of the film blown by the LDPE extrusion die head are better than the film blown by the HDPE die head.
Different production costs: The production cost of the film blown by the LDPE extrusion die head is higher, while the cost of the HDPE die head is relatively low.
WHAT IS A HDPE EXTRUSIONS DIE HEAD USED FOR?
Some packaging films commonly used in daily life such as shopping bags, garbage bags, storage bags, etc.
The production of thicker film or some less demanding packaging film.
WHAT IS THE DIFFERENCE BETWEEN PVC EXTRUDER AND POLYETHYLENE EXTRUDER?
PVC and polyethylene extruders differ primarily in the materials they process and their specific requirements. PVC extruders often use twin-screw designs to handle the material's higher viscosity and require lower processing temperatures (160-200°C) to avoid degradation. They also need more additives like stabilizers and plasticizers. Polyethylene extruders, typically single-screw, handle materials like HDPE and LDPE, which have lower viscosity and require higher processing temperatures (180-250°C). PE extruders generally need fewer additives and simpler cooling systems. Die designs and cooling/calibration methods also vary to accommodate the distinct flow characteristics and stability needs of each material.
