Bynel® 4140

BYNEL® Series 4100 resins are anhydride-modified, linear low-density polyethylene (LLDPE) resins. All 4100 series resins are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resin.

BYNEL 4140 is a grade with a higher level of anhydride modification, and is mainly intended for use as a component in a blend with other polyolefin resins. It is not intended for extrusion in its pure form in typical extrusions or coextrusions.

BYNEL 4100 series resins adhere to a variety of materials. They are most often used to adhere to EVOH, polyamide, PE and ethylene copolymers.
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

LLDPE resins are known for their temperature resistance, clarity and toughness.
These physical properties make the 4100 series 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.
