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
1. Bottles and Containers: HDPE Extrusions is commonly used to produce milk jugs, detergent bottles, and other containers for liquids.
2. Pipes and Fittings: HHDPE Extrusions are used for water supply, sewage, gas distribution, and industrial applications due to their durability and resistance to corrosion.
3. Irrigation Systems: HDPE Extrusions and tubing are used in irrigation systems for their flexibility and resistance to chemicals.
4. Toys: Many children's toys are made from HDPE due to its safety and durability.
5. Household Items: Products like cutting boards, storage bins, and laundry baskets are often made from HDPE.
6. Furniture: Outdoor furniture, such as chairs and tables, are made from HDPE Extrusions for their weather resistance.
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.

LDPE Extrusion Die Head Film blowing LDPE die heads are often used to produce high-quality films. The polyethylene blown film extrusion head is mainly composed of feed port, flow channel, film head and positioning components, and adopts the principle of fluid mechanics under high temperature and high pressure to form a high-speed rotating flow field in the die head, so as to achieve transverse film blowing. The polyethylene film extrusion head is characterized by excellent film blowing quality, high transparency, high strength and high toughness, suitable for blowing some high-quality, high transparency requirements of the film, such as food film, medical film, industrial packaging film and so on. Key Considerations For lDPE Die Head 1. Material Compatibility Material of Construction: The die head should be made from materials that are compatible with LDPE, typically high-grade tool steels or stainless steels that can withstand the processing temperatures and pressures. Corrosion and Wear Resistance: The material should also be resistant to corrosion and wear to ensure a long service life. 2. Temperature Control Heating Zones: Proper temperature control is crucial for maintaining the viscosity of LDPE. The die head should have multiple heating zones to ensure uniform temperature distribution. Thermal Insulation: Good thermal insulation helps in maintaining the desired temperature and reduces energy consumption. 3. Pressure Management Pressure Drop: The design should minimize pressure drop across the die to ensure consistent flow and reduce the risk of defects. Pressure Sensors: Incorporate pressure sensors to monitor and control the pressure within the die head. Design and Function of lDPE Die Head The die head of the film blowing machine is composed of a die body (die core, die cylinder, die ring) and a heater (heating ring). The first material selection is to select the corresponding material. LDPE application: Suitable for food, pharmaceutical, fiber product, daily chemical supplies packaging. Due to the poor mechanical properties of single-layer PE film, it is also used as the inner layer of composite packaging bags, that is, multi-layer composite film heat sealing substrate.
