M21E730

M21E730 is a low density polyethylene (LDPE) ionomer. It is produced by the neutralization of an ethylene methacrylic acid (MAA) copolymer. Exhibits very high impact strength, very good drawdown, good optical properties and very low resistance to tear propagation in both machine & transverse directions. Is suitable for processing by coextrusion & blown film extrusion. It can be blended or coextruded with other types of polyethylene to tailor performance. Recommended for easy tear film applications such as collation shrink film, envelopes, overwrap and bags. It complies with the EU Regulation (EC) No 1935/2004, Commission Regulation (EU) No 10/2011, and Commission Regulation (EC) No 2023/2006. Meets the relevant requirements of regulations including RoHS-2011/65/EU, WEEE-2002/96/EC, EoL-2000/53/EC, Regulation (EC) 1907/2006, and REACH-Regulation No. 1907/2006.
