DuPont™ Surlyn® E185SB Ionomer Resin

Surlyn® E185SB is an ionomer of an acid copolymer resin. It is designed for coextrusion with high-density polyethylene in peelable seals applications. It can be used in extrusion equipment designed to typically process polyethylene resins. Uses: Film Packaging Sealants Composition: Proprietary Formulation Surlyn® E185SB can be coextruded with HDPE to provide delamination-type peelable seals. The seal strength can be controlled by processing conditions and/or the thickness of Surlyn® E185SB layer. Thickness is typically in the range of 5 to 15 microns (0.20 to 0.60 mils). Other benefits of Surlyn® E185SB include: Very low seal initiation temperature· Broad sealing temperature range Contains “Slip” and “Antiblock” Surlyn® E185SB complies with the Food and Drug Administration regulation 21 CFR 175.300 – – ‘Resinous and polymeric coatings’. This regulation describes polymers that may be used as coatings on a metal substrate for packaging, transporting, or holding food, subject to meeting the extractive limitations in the regulation. SURLYN E185SB also complies with FDA regulation 21 CFR 175.320 – – ‘Resinous and polymeric coatings for polyolefin films’, subject to meeting the extractive limitations in the regulation. SURLYN E185SB contains 0.45 wt.% of a slip agent that complies with 21 CFR 175.300(b)(3)(xxv) – ‘Release agents’ and 21 CFR 175.320(b)(3). This slip agent cannot exceed 0.0085 milligram per square centimeter (0.055 milligram per square inch) in the finished food-contact article.
