Westlake EC850AA Low Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE)
Material Notes:	WESTLAKE low-density polyethylene EC850 is a resin designed for applications where high coating speeds and good drawdown are required. The combination of high melt index and low density provides good heat seals at high packing or sealing rates. It also demonstrates good adhesion to paper, provides a good moisture barrier, and is heat-sealable at low temperatures. Application/Uses Coatings for paper/paperboard Food contact applications FDA: This material complies with FDA regulations in 21 CFR, section 177.1520. Kosher Compliant.
