Description
Comprehensive Introduction to POLIRAN LH-0075 LDPE | High-Strength and High-Stability Film Grade
Low-Density Polyethylene LDPE LH 0075, also known as POLIRAN LH-0075, is a high–molecular weight film-grade resin produced by Bandar Imam Petrochemical Company under license from TOSOH CORP. This grade is specifically engineered for blown film applications, and due to its unique combination of mechanical and processing properties, it is widely used in packaging industries, industrial films, and flexible products.
Key Features of LH-0075
This grade is formulated to ensure excellent processability at high production speeds while guaranteeing the quality of the final film.
⭐ 1. Outstanding Mechanical Strength
Films produced with LDPE LH 0075 exhibit:
- High tensile strength in both MD and TD
- Excellent impact resistance (Dart Impact ≥ 120 g)
- Suitable stiffness for industrial packaging
These characteristics ensure superior performance against pressure, puncture, and tearing.
⭐ 2. Easy and Stable Processability
This grade is fully compatible with all types of film extrusion lines and offers:
- Uniform and stable extrusion behavior
- Excellent dimensional stability in the film
- Suitability for fully automatic machinery
Optimal performance is achieved at a melt temperature of 180–210°C.
