What is LLDPE ?

LLDPE, a thermoplastic in the polyethylene family, features a distinctive structure with linear and branched ethylene monomer chains. It is prized for its flexibility, toughness and resilience, with high tensile strength and resistance to impacts, extreme temperatures, UV radiation and chemicals. LLDPE finds common use in film and packaging production due to its puncture resistance, serving applications like stretch films, plastic bags and liners. Additionally, it’s employed in manufacturing consumer goods like toys, containers and automotive components.

LLDPE’s affordability and ease of processing, including blow molding, injection molding and extrusion, contribute to its extensive usage across various industries.


There are several different MFI levels available in LLDPE grade, including:

  • Low MFI (Melt Flow Index): LLDPE with a low MFI, often less than 1 g/10 min, is suitable for applications where precise control over flow and processing is necessary. It is commonly used for manufacturing thicker-walled parts and intricate products, offering enhanced flow control and stability during molding.

  • High MFI (Melt Flow Index): LLDPE with a high MFI, often exceeding 10 g/10 min, is preferred for applications where rapid processing and high production rates are essential. It excels in providing excellent flowability and is commonly used for thin-walled products and situations requiring fast manufacturing.

  • Medium MFI (Melt Flow Index): LLDPE with a medium MFI, typically ranging from 1 to 10 g/10 min, is versatile and well-suited for a broad spectrum of molding applications. It strikes a balance between flowability and processability, making it suitable for various part geometries and sizes.

Some of the application usage of LLDPE are :

LLDPE is a versatile material extensively used in multiple industries. One key application is in packaging films, where its flexibility, toughness and puncture resistance excel. These films are utilized in food packaging, industrial packaging, agricultural films and consumer product packaging, safeguarding contents from moisture, oxygen and contaminants.

LLDPE is also a preferred choice for rotomolding, a process that crafts hollow, three-dimensional products such as containers, tanks and playground equipment. Its durability and ease of processing, along with excellent impact resistance, make it ideal for this method.

Furthermore, LLDPE finds its way into injection molding, producing a variety of goods like toys, containers, automotive parts and more, thanks to its ease of flow, toughness and impact resistance.


Metallocene Linear Low-Density Polyethylene (mLLDPE) is an advanced form of LLDPE that is produced using metallocene catalysts. These catalysts are highly precise and allow for greater control over the polymer’s structure, resulting in enhanced material properties. Metallocene LLDPE offers improved performance characteristics, such as a narrower molecular weight distribution and superior melt strength compared to conventional LLDPE.

One of the key advantages of metallocene LLDPE is its exceptional film processing capabilities. It can produce thinner, stronger and more consistent films for packaging applications. This makes it particularly valuable for applications where downgauging (reducing film thickness while maintaining performance) is desired, as it can lead to material and cost savings.

Metallocene LLDPE is also known for its excellent sealing properties, making it ideal for applications where a reliable and hermetic seal is crucial, such as in food packaging. It provides enhanced puncture resistance, tear strength and seal integrity, resulting in high-quality packaging materials that protect and preserve the contents effectively.

In rotomoulding, LLDPE is used to create a wide variety of hollow, three-dimensional products, including tanks, playground equipment, kayaks and more. It is well-suited for these applications thanks to its excellent impact resistance, UV stability and resistance to chemicals and environmental factors.

Variety: LLDPE for rotomoulding comes in various grades, each tailored to specific needs. Natural LLDPE is translucent and commonly used for applications where visibility or translucency is desired. Colored LLDPE grades offer a wide array of vibrant colors for products requiring aesthetics. Additionally, specialty LLDPE grades are designed for applications with unique requirements, such as enhanced UV resistance or fire retardancy.

Grades: Rotomoulding LLDPE grades are typically categorized by their melt flow index (MFI), which determines their flow characteristics during the molding process. Low MFI LLDPE is ideal for complex and thicker-walled parts that require precise flow control. Medium MFI LLDPE is versatile and suitable for a broad range of rotomolded products, offering a balance between flowability and processability. High MFI LLDPE is used for faster production, particularly for thin-walled parts and when rapid molding is required. The choice of LLDPE grade depends on the specific design and performance requirements of the rotomolded product.
