BYNEL® Series 4200 resins are anhydride-modified, low-density polyethylene resins containing anhydride. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins.

BYNEL 4200 series resins are specifically designed to provide high interlayer adhesion between: EVOH, polyamide, PE, ethylene copolymers and ionomers.
Applications in which the use of these resins is advantageous include:
  • barrier bag-in-box films
  • large pouches for hospital, restaurant or institutional uses
  • rigid containers in which PE is the structural component.
In addition, with their high adhesion to ionomers, these resins are advantageous in multi-layer ionomer/barrier constructions designed to package oily products.
