PRIMACOR 1430
PRIMACOR™ 1430 Copolymer is an ethylene acrylic acid copolymer that provides good sealability, hot tack and excellent adhesion to polar (foil, ylon, etc.) materials. It also provides excellent toughness, clarity and tear resistance.
Introduction
PRIMACOR™ 1430 Copolymer is an ethylene acrylic acid copolymer that provides good sealability, hot tack and excellent adhesion to polar (foil, ylon, etc.) materials. It also provides excellent toughness, clarity and tear resistance.
PRIMACOR™ 1430 Copolymer exhibits:
· Adhesive layer of sealant layer in flexible packaging structures
· For blown or cast film extrusion
· Used where adhesion to nylon or foil is desired

Extrusion Notes
Equipment used to process this resin should be constructed of corrosion resistant materials. Dies and adapters are
recommended to be stainless and/or duplex chrome or nickel plated.
Notes
These are typical values and are not be construed as specifications. The physical properties are highly dependent on the
manufacturing conditions. So customers should confirm performances by their own tests.
