BYNEL 41E871 is a grade with a medium-high level of anhydride modification, and is mainly intended for use as a component in a blend with other polyolefin resins.

Physical properties of BYNEL Series 4100 resins are typical of linear low-density polyethylene resins with similar density and melt index values. Use of these adhesive resins in coextruded PE/barrier structures offers improved thermal resistance over that of ethylene vinyl acetate-based adhesive resins.

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, which 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.

BYNEL 41E871 resin conforms with the Code of Federal Regulations, Title 21, Paragraph 175.105, covering the use of adhesive interlayers in composite packages for food use. This regulation describes adhesives that may be safely used as components of articles intended for use in packaging, transporting or holding food. This regulation requires that either (1) the adhesive is separated from the food by a functional barrier, or (2) the quantity of adhesive which contacts fatty or aqueous foods does not exceed the trace amounts at the seams or edges. Customers should satisfy themselves that the food contact material is serving as a functional barrier to the adhesive.
