Material Notes:
Elvaloy® 1820 AC is intended for film coextrusion, compounding and injection molding. Due to its high melt flow rate, it also can be used in extrusion coating/lamination. Elvaloy® 1820 AC has good adhesion to carious substrates (OPA, OPP, paperboard, etc.), gives excellent sealing properties and has high filler acceptance.Elvaloy® 1820 AC is easily processed on standard equipment used for low density polyethylene.Information provided by DuPont.
