Sabic Linear Low-Density Polyethylene (LLDPE) Product Details
Product Description
Linear Low-Density Polyethylene (LLDPE) is a versatile thermoplastic polymer derived from ethylene. It is known for its high tensile strength, excellent impact resistance, and superior flexibility compared to conventional LDPE. Due to its enhanced mechanical properties and processability, LLDPE is widely used in packaging films, molded products, and industrial applications.
Key Features:
- High tensile strength and puncture resistance
- Excellent flexibility and elongation properties
- Superior impact resistance at low temperatures
- High transparency and glossy surface
- Outstanding chemical and moisture resistance
- Good processability for film extrusion, molding, and rotational molding
Production Process
LLDPE is manufactured through a low-pressure polymerization process using ethylene and α-olefins such as butene, hexene, or octene as comonomers. The production involves the following steps:
- Raw Material Preparation – Ethylene and comonomers are purified and fed into the reactor.
- Polymerization – The polymerization occurs using a catalyst system in gas-phase or solution-phase reactors.
- Separation & Purification – Unreacted monomers are separated and recycled, while the polymer is purified.
- Extrusion & Pelletizing – The molten polymer is extruded into strands, cooled, and cut into uniform granules.
- Quality Control & Packaging – The final product undergoes stringent quality testing before being packed for distribution.

Frequently Asked Questions (FAQ)
Q1: What is the difference between LLDPE Injection, Blow Molding, and Film grades?
A: LLDPE Injection grade is optimized for producing molded plastic parts that require high flexibility and impact resistance. Blow Molding grade is used for manufacturing lightweight yet durable containers, such as squeeze bottles and industrial packaging. Film grade is primarily designed for stretchable plastic films, widely used in food packaging, agricultural films, and industrial wrapping applications due to its excellent puncture and tear resistance.
Q2: What is the minimum order quantity (MOQ)?
A: Our MOQ is 1 ton, with bulk pricing available for larger orders.
Q3: Can I request a sample before ordering?
A: Yes! We provide free samples, and you only need to cover shipping costs.
Q4: How do you ensure product quality?
A: We follow strict quality control procedures, including raw material inspection, in-process monitoring, and final testing.
Q5: What are the payment terms?
A: We accept T/T, L/C, and Western Union, with negotiable terms for bulk orders.
