Abstract

Low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) belong to polyethylene group of thermo-plastics. LDPE is generally the softest and least crystalline of all the polyethylene. LDPE has a unique combination of properties namely toughness, high impact strength, low-brittleness temperature, flexibility, processibility, film transparency, chemical resistance and having a density of 0.91 – 0.94. LDPE applications are mostly film based. The most common application areas are in general food packaging, milk pouches, industrial products, textiles, frozen foods, agriculture and horticulture section etc. LLDPE has all the advantages of LDPE together with the added benefit of low energy output which leads to a saving of over 20% in the manufacturing cost. The use of LLDPE has been predominantly in blends with LDPE as far as film extrusion is concerned. LLDPE and LDPE blended film are used for milk packaging, nursery bags, heavy duty sacks and general purpose bags.
