LDPE & LLDPE
Low density and linear low density polyethylene, supplied to a declared melt flow index and density.
LDPE and LLDPE — what actually differs
| LDPE | LLDPE | |
|---|---|---|
| Structure | Long-chain branching | Short-chain branching, linear backbone |
| Processing | Easier bubble stability, lower motor load | Higher melt viscosity, needs more power |
| Film properties | Better clarity and gloss | Higher puncture and tear strength |
| Common practice | Blended — LLDPE for strength, LDPE for processability and optics | |
Grade families
| Family | Typical use |
|---|---|
| Film grade | Packaging film, agricultural film, shrink and stretch film |
| Extrusion coating | Paper and board lamination |
| Injection grade | Closures, flexible housewares |
| Cable grade | Insulation and jacketing |
