LDPE 2004TX37, developed by Laleh Petrochemical Company, is a premium-grade low-density polyethylene (LDPE) specifically designed for blown thin film applications. It combines exceptional mechanical and optical properties, making it highly valued in industries requiring high clarity, gloss, and excellent processing performance. Below, we explore its properties, applications, additives, and other relevant details.
Key Features and Benefits
-
Exceptional Optical Properties:
- High Gloss (45°): 53%
- Low Haze: 9.5%
- Clarity: 23 mV (SABTEC Method)
These properties make LDPE 2004TX37 ideal for applications demanding high transparency and aesthetic film quality, such as protective films, food packaging, and general-purpose packaging (source).
-
Mechanical Strength:
The material provides an excellent balance between tensile strength, elasticity, and tear resistance, making it suitable for diverse thin film applications:- Impact Strength: 15 kJ/m
- Tear Strength TD (Transverse Direction): 30 kN/m
- Tensile Stress at Break (TD/MD): 15 MPa / 27 MPa
-
Additives for Enhanced Performance: The formulation includes:
- Anti-oxidants: To prevent polymer degradation.
- Slip Agent (900 ppm): Reduces surface friction for smoother handling.
- Anti-block Agent (800 ppm): Prevents film sheets from sticking together after processing.
These additives significantly improve post-production handling, storage, and user experience for packaging applications (source).
-
Processing and Safety Characteristics:
- Melt Flow Rate (MFR): 4.7 dg/min, ensuring versatile and smooth extrusion performance.
- Density: 921 kg/m³, offering balance between lightness and durability.
In addition, LDPE 2004TX37 is noted for its low gel content, low odor, and non-toxic formulation, making it suitable for both industrial and food-grade applications (source).
Primary Applications
-
General Packaging Films: The material is a popular choice for textile packaging due to its high optical clarity and mechanical properties.
-
Protective Films: Its tear strength and clarity make it ideal for surface protection films.
-
Food Packaging: With its low odor/taste profile and transparency, it’s suitable for hygienic, high-standard food applications.
