Key Features of HDPE HFI 5110
According to the official datasheet, this grade offers a set of superior characteristics that make it ideal for producing durable films and heavy-duty bags:
• Excellent tear resistance
• High melt strength
• Very good printability and lamination quality
• Suitable for thin films of 15 to 50 microns
• Good processability in blown-film extrusion
Applications and Uses
HDPE HFI 5110 is specifically recommended for producing:
• Blown films
• Single-layer and multi-layer packaging
• Shopping bags and high-strength carrier bags
• High-quality printable films
Due to its mechanical strength and stability, this grade is one of the main choices for manufacturers of shopping bags and industrial films.
Physical and Mechanical Properties (Typical Values)
The values below are extracted from the official datasheet and are important for understanding the performance of the product:
| Property | Value | Unit | Standard |
|---|---|---|---|
| HLMI (190°C/21.6 kg) | 10 | g/10 min | ISO 1133 |
| Density | 0.951 | g/cm³ | ISO 1183 |
| Tensile modulus | 1050 | MPa | ISO 527 |
| Tensile strength (MD/TD) | 55 | MPa | ISO 527 |
| Elongation at break (MD/TD) | 580/620 | % | ISO 527 |
| Elmendorf tear strength (MD/TD) | 250/800 | mN | ISO 6383-2 |
| Melting point | 132 | °C | ISO 3146 |
| Vicat A/10N | 127 | °C | ISO 306 |
These values show that HDPE HFI 5110 is a grade with remarkable strength and excellent tensile performance.
Additives Included in the Formulation
This grade contains essential additives for processing stability:
• Antioxidant: Yes
• Zinc stearate: Yes
• Anti-block: No
• Slip agent: No
The absence of slip and anti-block additives improves printing and lamination quality.
Recommended Processing Conditions
For the best performance in blown-film extrusion, the following melting and processing conditions are recommended:
• Extruder temperature profile: 200 to 235°C
• Blow-up ratio (BUR): 3 to 5
• Film thickness: 15 to 50 microns
This temperature range increases bubble stability and enhances the mechanical properties of the final film.
Safety and Handling
• For food or medical applications, separate compliance certificates must be checked.
• Molten polymer may degrade when exposed to air and produce an unpleasant odor.
• Proper ventilation is required during extrusion.
• Keep away from flame and heat sources.
Storage Conditions
• Avoid direct sunlight
• Store in a cool, dry place below 50°C
• Best used within 6 months after receipt
Improper storage may lead to discoloration, unpleasant odor, or reduced product quality.
Conclusion
HDPE HFI 5110 is a powerful and specialized grade for producing strong thin films. Its high tear strength, excellent printability, high modulus, and melt stability make it a reliable choice for manufacturers of shopping bags, multilayer packaging films, and industrial applications.
For anyone involved in polyethylene film production, HFI 5110 is definitely a grade worth having in the production line.
