Description
🌟 HDPE 7000F Film Grade
The Ideal Choice for Thin, Strong & Food-Safe Films
🧪 Product Overview
HDPE 7000F is a high-density polyethylene (HDPE) film grade produced by Mehr Petrochemical Company using a bimodal process licensed by Mitsui Chemicals, Japan. Designed for superior film performance, this material is perfectly suited for applications that demand both thin film capability and mechanical strength.
✅ Key Features
🔹 High tensile strength with excellent impact resistance
🔹 Ultra-thin film capability (recommended thickness: 10–25 microns)
🔹 Excellent moisture barrier properties
🔹 Very low gel content for smooth and consistent film
🔹 Suitable for direct food contact
🔹 Outstanding UV resistance and performance at sub-zero temperatures (below -60°C)
🔹 High stiffness and good processability
🎯 Typical Applications
🛍️ Shopping and T-shirt bags
🗑️ Garbage and waste disposal bags
🍱 Food packaging films
📦 Liner bags and industrial packaging
🧴 Enhanced ultra-thin industrial films

⚖️ Comparison: HDPE 7000F vs. EX5
Choosing the Right Film Grade Based on Performance, Processability & Application
| Feature | HDPE 7000F | EX5 |
|---|---|---|
| Polymer Type | Bimodal HDPE | Unimodal HDPE |
| Technology Origin | Mitsui Chemicals – Japan | Typically Ziegler-Natta |
| Melt Flow Index (MFI) | Very low (0.03 – 0.05) ⇒ Ideal for strong thin films | Higher (> 0.07) ⇒ Easier to process, lower mechanical strength |
| Tensile Strength | Very high | Moderate to high |
| Impact Resistance | Excellent (Dart Impact: 139g) | Moderate |
| Gel Content | Very low | Higher than 7000F |
| Film Transparency | Matte (Haze: 85.5%) ⇒ Suitable for non-clear films | Varies – often clearer depending on the source |
| Food Contact Approval | ✅ Yes | Depends on grade and supplier |
| Thin Film Capability (10–25 microns) | Excellent | Usable, but with thickness limitations |
| Environmental Stress Crack Resistance (ESCR) | >1000 hours | Generally lower than 1000 hours |
| Cost | Higher, due to advanced technology and performance | More economical for general-purpose films |
📝 Conclusion
- HDPE 7000F is the ideal choice for premium applications requiring superior mechanical properties, food safety, and ultra-thin film production.
- EX5 is suitable for general-purpose packaging where cost-effectiveness and moderate performance are acceptable.
