Description
What is HDPE EX5 and Why Is It an Ideal Choice for Polyethylene Film Manufacturers?
Producer: Jam Petrochemical Company
HDPE EX5, also known by the industrial code HM9450F (EX5), is one of the best-selling and highest-quality high-density polyethylene grades used for blown film production. This grade is produced through ethylene slurry polymerization with 1-butene comonomer, and its bimodal molecular structure provides a unique combination of strength, excellent processability, and high mechanical resistance.
Key Features
1. High Viscosity and Strength (High Molar Mass)
HDPE EX5 is a high-molecular-weight film grade, which increases tensile strength and tear resistance. This makes it highly suitable for industrial and heavy-duty packaging applications.
2. Excellent Stiffness and Drawability
Thanks to its bimodal polymer structure and density of 0.947–0.951 g/cm³, this grade offers high stiffness and good formability—ideal for producing paper-like film with enhanced rigidity.
3. Outstanding Processability in Blown Film Production
Due to its optimized MFR and FRR ratios
(MFR 8 g/10 min at 190°C/21.6 kg and 0.28 g/10 min at 190°C/5 kg),
HDPE EX5 performs exceptionally well in film extrusion lines.
Its superior processability results in:
- Uniform film thickness
- Minimized fish eyes (less than 3)
- Clean, high-quality film surfaces
4. Stabilizing Additives
The product contains antioxidants, process stabilizers, and lubricants, which improve durability and performance during extrusion.

Prominent Characteristics
1. High Mechanical Strength and Stiffness
Its high molecular weight enhances strength, tensile resistance, and film stability—crucial for applications like shopping bags and industrial packaging.
2. Excellent Surface Quality & Low Fish-Eye Count
With fewer than 3 fish eyes, HDPE EX5 enables the production of extremely uniform films with a clean, professional appearance.
3. Superior Processability
Thanks to its balanced MFR range, this grade offers optimal performance in blown-film extruders, enabling:
- Better thickness control
- More stable film bubbles
- Higher production speeds
4. Presence of Stabilizing Additives
HDPE EX5 contains:
- Antioxidants
- Process stabilizers
- Processing aids (lubricants)
- Acid scavengers
These additives ensure smoother production and improved final film quality.
Applications of HDPE EX5
HDPE EX5 is an excellent choice for manufacturers of polymeric films and is used for:
- Shopping bags (carrier bags)
- Freezer and sandwich bags
- General-purpose packaging films
- Paper-like films
- Garbage bags and industrial packaging
Due to its high strength and exceptional surface quality, this grade is one of the most popular choices for both light and heavy-duty packaging industries.
Why Choose HDPE EX5?
Choose this grade if you need a product that offers:
- Trouble-free blown-film processing
- High stiffness and excellent mechanical strength
- Superior surface appearance
- Versatility for both light and heavy packaging applications
HDPE EX5 produced by Jam Petrochemical Company is exactly the grade you need.
