ExxonMobil®LDPE

LD 362 series (Low Density Polyethylene for blow film applications)

Key features

Recommended processing conditions and resin handling

LD 362 series are EVA LDPE grades, good mechanical and sealing properties.Several additive combinations are available according to the required surface properties.They are typically used in freezer packaging for its low temperature  resistance and in lamination/extrusion film.

Melt temperature : 160 °C
Blow-up ratio : 2 : 1 (or higher)
Film thickness range : 25 -80 µm
