LLDPE resin, the full name is linear low density polyethylene , is non-toxic, tasteless, and odorless milky white particles with a density of 0.918~0.935g/cm3. Compared with LDPE, LLDPE resin has the advantages of high strength, good toughness, strong rigidity, heat resistance, cold resistance, etc., and also has good environmental stress cracking resistance, impact strength, tear resistance, etc. solvent etc. Therefore, LLDPE resin can be widely used in fields such as industry, agriculture, medicine, hygiene and daily necessities.
LLDPE is a copolymer of ethylene and a small amount of higher α-olefins polymerized under high pressure or low pressure under the action of a catalyst. The main chain structure of Linear low-density polyethylene (LLDPE) is linear, because its processing performance and gloss are superior to high density polyethylene ( HDPE), and its puncture resistance, tear resistance and environmental stress cracking resistance are superior to ordinary low density polyethylene ( LDPE), so LLDPE resin granules have great advantages in the field of film products, and are widely used in agricultural films, packaging bags and heavy-duty packaging films, etc. As a leading supplier, Fengbai can provide various brands of LLDPE resin for you, such as Sabic, Marlex, Qapco, ExxonMobil, Dow, Borouge, Lyondellbasell,etc.

What Is LLDPE Resin Used For?
The main application fields of LLDPE resin are agricultural film, packaging film, molding, pipe and wire and cable, coating products, etc. And its latest application can be used as a mulch film for the lining of waste residue landfill and waste liquid pool to prevent leakage or pollution the surrounding area.
LLDPE granules has excellent rheology or melt fluidity. LLDPE is less shear sensitive because of its narrow molecular weight distribution and short chain branches. During the shearing process, LLDPE maintains a greater viscosity and is therefore more difficult to process than LDPE with the same melt index. In extrusion, the lower shear sensitivity of LLDPE allows for faster stress relaxation of the polymer molecular chains, and thus the physical properties are less sensitive to changes in blow-up ratio. In melt extension, LLDPE generally has a lower viscosity at various strain rates. That is to say, it will not strain harden when stretched like LDPE.
