PP Homopolymer for Bi-axially oriented film

PP 521P is a non formulated grade, specially developed for bi-axially oriented PP (BOPP) film extrusion with a very specific molecular structure providing ultimate properties required for the stenter film process.
Films produced using PP 521P will exhibit:
  • Consistent processability
  • Excellent optical properties
  • High tensile properties
  • Low residual ash
  • Film produced can be metalized

Typical Applications
PP 521P can be used as core layer in co-extruded film and/or as base material for plain films used for stationary, dry food bags, synthetic paper and heat sealable packaging films.
