Dow Bynel® 4157 Adhesive Resin
Categories: Polymer; Thermoplastic; Ethylene Vinyl Acetate

Material Notes: Bynel® Series 4100 resins are anhydride-modified linear low-density polyethylene (LLDPE) resins. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins.

Applications:Bynel® Series 4100 resins adhere to a variety of materials. They are most often used to adhere to EVOH, polyamide, PE, ionomers, and ethylene copolymers.

Bynel® Series 4100 resins can be used in coextrusion processes including:

  • blown film
  • cast film/sheet
  • blow molding melt and solid phase thermoforming
  • sheet and tubing
  • Bynel® 4157 can also be used in coextrusion coating. LLDPE resins are known for their temperature resistance, clarity and toughness. These physical properties make the Bynel® Series 4100 resins work well in applications such as:

  • boil-in-bag structures
  • blow molded containers in which drop strength is important
  • bag-in-box films
  • film where LLDPE is the heat seal layer
