Chevron Phillips Marlex 5428 is a low-density polyethylene (LDPE) produced by Chevron Phillips Chemical.
Physical Properties
Density: The base density, measured per ASTM D1505, is 0.930 g/cc (0.0336 lb/in³), serving as a foundational parameter for material design and selection.
Water Vapor Transmission: Measured by ASTM F1249, the water vapor transmission rate is 14.0 g/m²/day (0.902 g/100 in²/day).
Oxygen Transmission Rate: Determined via ASTM D3985, the oxygen transmission rate is 3600 cc/m²/day (232 cc/100 in²/day).
Antiblock Level: At 10,000 ppm, the additive concentration prevents film sticking during processing or storage, enhancing manufacturing efficiency.
Slip Level: Set at 1000 ppm, it ensures low surface friction for smooth handling and processing, ideal for high-speed packaging operations.
Polymer Properties:
Base Material: Low Density Polyethylene (LDPE)
Modification Features:
Optimized for cast film applications with a focus on superior openability for easy film separation.
Incorporates high antiblock and slip levels to prevent sticking during production and storage.
Ideal for food wraps and industrial liners requiring non-stick properties.
Applications:
Cast Film Packaging: Produces food wraps, bakery bags, and frozen food liners that require non-stick properties and easy opening for consumer convenience.
Industrial Liners: Creates durable liners for bulk material storage (e.g., chemicals, grains) and agricultural covers that resist tearing and sticking during handling.
Laminated Films: Acts as a release layer in laminated labels, pouches, and flexible packaging to ensure smooth unwinding on high-speed lines.
