Product type
Linear Low Density Polyethylene (LLDPE) granules are a type of thermoplastic made from the polymerization of ethylene and other alpha-olefins. This material is characterized by its flexibility, toughness, and resistance to impact and stress cracking. LLDPE granules are typically used in the production of films, sheets, and various molded products due to their excellent processing characteristics and adaptability to different manufacturing techniques.
| Density | 0.910 to 0.925 g/cm³ |
| Melt Flow Index | 0.5 to 20 g/10 min |
| Tensile Strength | 10 to 30 MPa |
| Elongation at Break | 300% to 700% |
| Processing Temperature | 160 to 220 °C |
When selecting LLDPE granules, consider the specific application requirements such as density, melt flow index, and tensile strength. It is essential to specify any necessary certifications or grades based on industry standards, especially for food packaging or medical applications. Additionally, provide information on the desired quantities and any specific processing conditions to ensure compatibility with your manufacturing processes.

LLDPE has a linear structure with short branches, providing greater strength and flexibility compared to the more branched structure of LDPE.
Yes, LLDPE is recyclable, and many facilities accept it for recycling.
Common uses include plastic bags, agricultural films, and containers.
Yes, LLDPE is often used in food packaging due to its safety and barrier properties.
LLDPE typically performs well in temperatures ranging from -50 °C to 80 °C.
LLDPE is more flexible and has better impact resistance than HDPE, which is more rigid and has higher tensile strength.
