Key Features and Advantages of PPH‑FCP80

  • Film-Optimized: Designed for use as a core or middle layer in multilayer cast films, offering strength without compromising transparency.
  • High Tensile Strength & Elongation: ≥ 150% elongation at break ensures excellent stretchability and processing performance.
  • High Isotacticity: ≥ 95.5% isotactic index improves crystallinity, enhancing rigidity, strength, and thermal stability.
  • Low Haze (≤ 6%): Ensures clear, high-clarity films.
  • Moderate Melt Flow (~MI7): Balances good processability with structural integrity during extrusion.

Main Applications

  1. Core or middle layer in multilayer films, especially in cast film processes for packaging, laminated, or functional films.
  2. Provides load-bearing capacity and crack resistance in co-extruded multilayer films.
  3. Common applications include food packaging films, industrial packaging films, agricultural films, and laminated films requiring high strength and clarity.

Comparison with Other PP Film Materials

Compared with general injection-molding PP, SK PPH‑FCP80 offers optimized melt flow and higher elongation for film applications.

Compared with ethylene-propylene copolymer PP films, PP homopolymer delivers superior rigidity, strength, and heat resistance, but slightly lower flexibility and heat-sealing performance.

For high sealability or special functionalities (antistatic properties, optical clarity), it is recommended to combine with copolymer or modified PP layers.

Processing Guidelines

  • Maintain a proper temperature range during cast film extrusion to ensure uniform melt and moderate shear for high-quality film.
  • Ideal for multilayer films (e.g., A/B/A or A/B/C structures), serving as the core layer to improve mechanical strength and resistance to tearing or cracking.
  • Cooling rate, stretch ratio, and extrusion/blown film speed strongly influence final film properties such as transparency, strength, and surface clarity.
