Dow DOWLEX™ 2045G LLDPE Resin

Physical Properties

• Density: Measured by ASTM D792, the density is 0.920 g/cc (0.0332 lb/in³). It provides a balance of stiffness and flexibility for packaging.
• Thickness: With a thickness of 50.8 microns (2.00 mil), it offers enhanced durability. It can resist punctures well, making it suitable for packaging items that need extra protection during handling.
• Melt Flow: According to ASTM D1238, the melt flow rate is 1.0 g/10 min. This rate ensures good processability during manufacturing, allowing for consistent shaping of the material into products.

Polymer Properties:

• Base Material: Ethylene – based copolymer (LLDPE)
• Modification Features:
  
  • Has a molecular structure friendly to conventional machinery, facilitating processing.
  • Incorporates tear – resistant additives, making it suitable for durable industrial films.
  • Boasts optimized optical properties, ideal for clear consumer packaging.
  • Is formulated for a variety of films, excluding silage stretch.

Applications:

DOWLEX™ 2045G is tailored for blown film extrusion and is widely used in the following applications:

1. Industrial Films:DOWLEX™ 2045G is extensively employed in industrial film applications due to its robust mechanical properties and processability. Specific uses include:
   
   • Geomembranes: Used in environmental applications like landfill liners, pond liners, and canal linings, where chemical stability and durability are critical to prevent leakage and withstand environmental stresses.
   • Industrial Liners: Suitable for drum and box liners in industries requiring protection from moisture, chemicals, or abrasion, ensuring product integrity during storage and transport.
   • Construction Films: Employed in vapor barriers, protective coverings, and temporary enclosures due to its tear resistance and ability to form thin, yet strong films.
2. Consumer Films:DOWLEX™ 2045G is also widely used in consumer-oriented applications, where its balance of flexibility, strength, and clarity provides significant advantages:
   • Food Packaging: Its compliance with FDA and EU regulations for food contact makes it suitable for flexible food packaging, such as frozen food bags, produce bags, and snack packaging. 
   • Shopping Bags: The resin’s toughness and tear resistance make it ideal for reusable and single-use shopping bags, capable of carrying heavy loads without breaking.
   • Trash Bags: Used in the production of high-strength trash bags for household and commercial use, offering resistance to punctures from sharp objects and durability under heavy loads.
3. Heavy-Duty Film Applications:The resin’s ability to produce thin films with robust profiles makes it a preferred choice for heavy-duty applications:
   • Agricultural Films: Used in greenhouse films and mulch films, where durability, tear resistance, and chemical stability are essential to withstand outdoor conditions and chemical exposure.
   • Pallet Wrap: Provides secure wrapping for industrial pallets, ensuring stability during transportation and storage.
   • Protective Packaging: Employed in bubble wrap or protective films for fragile items, offering cushioning and resistance to punctures.
