DOW LDPE™ PG 7004 Polyethylene Resin is typically used in extrusion coating applications. DOW LDPE PG 7004 Polyethylene Resin is designed for processing on conventional LDPE extrusion coating hardware at melt temperatures of 270 to 335°C, preferably less than 290°C, for best sensory performance. DOW LDPE PG 7004 Polyethylene Resin provides low volatile organic carbon (VOC) emissions in extrusion, contributing to low factory emissions and optimal sensory performance.

When processed on suitable hardware, DOW LDPE PG 7004 polyethylene resin exhibits:

Excellent draw down.

Good edge stability.

Low neck-in.

Complies with:

U.S. FDA-DMF

U.S. FDA 21 CFR 177.1520(c)2.2

EU, No 10/2011

Canadian HPFB No Objection

Consult the regulations for complete details.

Applications:

Paper board

Foil coatings for packaging food and non-food
