NatureWorks 6202D Hot Sale PLA Resin

Physical Properties

• Specific Gravity: In accordance with ASTM D792, the specific gravity of NatureWorks 6202D is 1.24 g/cc, significant for staple – fiber manufacturing.
• Melt Density: Measured by ASTM D1238 at 230 °C, the melt density of 1.08 g/cc ensures proper fiber formation during extrusion.
• Viscosity Measurement: The CD Internal Viscotek Method gives a relative viscosity of 3.1, affecting the resin’s flowability in fiber – making.
• Melt Flow: According to ASTM D1238, at 210 °C and 2.16 kg load, the 15 – 30 g/10 min melt flow optimizes staple – fiber production.

Polymer Properties:

1. Base Material: PLA (Polylactide)
2. Key Features & Characteristics:
   
   • Excellent Flexibility and Toughness: Engineered to be much more pliable than typical PLA, with significantly higher elongation at break, making it ideal for films that require durability and resistance to tearing.
   • Good Transparency: Produces clear films and parts, which is essential for transparent packaging and retail applications.
   • Outstanding Printability: Its surface properties allow for excellent ink adhesion, making it easy to print on for branding and graphics.
   • Bio-based and Compostable: As with all Ingeo PLA resins, it is derived from renewable resources and is industrially compostable, providing a sustainable alternative to petroleum-based plastics.

Applications:

The unique combination of flexibility and toughness makes NatureWorks 6202D suitable for a variety of flexible packaging products that require a sustainable profile.

• Film Packaging: Ideal for producing clear films for food, retail, and industrial packaging where flexibility and tear resistance are important.
• Twist Films: Its flexibility makes it a strong candidate for producing twist-wrap films for candies and other products.
• Lamination Films: Used as a layer in multi-layer laminates to provide a clear, tough, and bio-based barrier.
• Overwrap Films: Suitable for overwrapping various products due to its clarity and ability to form a tight, protective seal.

Processing Guidelines

NatureWorks 6202D is optimized for blown film extrusion and other film-making processes. Proper drying is crucial to prevent hydrolysis and ensure optimal product quality.

• Recommended Processing Temperature: 170°C – 190°C
• Drying: The resin should be dried to a moisture content of <250 ppm before processing. Recommended drying conditions are 4 hours at 40°C.
