Physical Properties

• Density: Measured by ExxonMobil method, the density is 0.921 g/cc (0.0333 lb/in³).
• Melt Flow: In accordance with ASTM D1238, at a temperature of 190 °C (374 °F) under a load of 2.16 kg (4.76 lb), the melt flow rate is 4.2 g/10 min.
• Neck In:
  
  • At 328 ft/min with constant output at 35 rpm (ExxonMobil Method), the neck in is 3.81 cm (1.50 in).
  • At 164 ft/min with constant output at 35 rpm (ExxonMobil Method), the neck in is 4.06 cm (1.60 in).
• Drawdown: At constant output at 35 rpm (ExxonMobil Method), the drawdown is 3.33 m/s (656 ft/min).

Polymer Properties:

• Base Material: Low-Density Polyethylene (LDPE)
• Key Features:
  
  • Precise neck-in/drawdown balance reduces edge trim waste by up to 20%.
  • High water vapor transmission rate (WVTR) barrier for dry food and pharmaceutical packaging.
  • Fast seal initiation for high-speed sachet and stick packaging lines.
  • Oxidation resistance for long-term shelf stability in packaged products.

Applications:

The versatile properties of LD 201.48 make it an ideal material for a range of demanding film applications.

• General Purpose Bags: Used to produce a variety of bags, including consumer bags, bread bags, fresh produce bags, and other general-purpose packaging.
• Food and Textile Packaging: Its balanced strength and optical properties are well-suited for films used in both food packaging and textile wrapping, offering product protection and visibility.
• Co-extrusion Films: The consistent processability and film properties make it a suitable component in multi-layer co-extrusion films where layers with different properties are required.
• Shrink Films: Its good mechanical properties and processability also make it a viable option for certain shrink film applications.
