Metallocene Polyethylene KN | Japan Polyethylene Corporation

Features

m-PE KN has excellent flexibility and strength.
It is used for various application and fields, from food packaging to everyday items.

01High Flexibility

KN is an ethylene/alpha-olefin copolymer produced by high-pressure manufacturing technology using a metallocene catalyst. KN is a plastomer with uniform composition which has both the properties of plastic and elastomeric. It exhibits excellent flexibility and strength.

02Low Melting Point

Compared to conventional high-pressure low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), it melts easily under heat, which means it can be sealed in a lower temperature (e.g., heat seal ability).

03High Strength

Compared to conventional high-pressure low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), KN has excellent strength. Therefore, by blending KN with polyethylene or polypropylene, you can strengthen your products.

04Low Odor

Low odor is one of KNs specifications; this is because it does not have much volatile, which generally causes resin specific odors.

Application

KN is used in products which its specific features; high flexibility, low melting point, and high strength are needed.
