Carmel Olefins Ipethene® 670 Low Density Polyethylene
Categories: Polymer; Thermoplastic; Polyethylene (PE); Low Density (LDPE); Low Density Polyethylene (LDPE), Extrusion Grade

Material Notes: IPETHENE® 670 is a low density polyethylene extrusion coating and lamination grade. This grade can be processed at high coating temperatures and coating speeds. It exhibits low neck-in and stable web edge, good adhesion to many substrates, excellent heat sealing properties, and low gel level.

APPLICATIONS

IPETHENE® 670 is mainly used for intermediate and light-weight high speed extrusion coating. It can be applied to various substrates such as paper, cardboard, aluminum foil, and flexible films like nylon, cellulose and polyester. The coated substrates can be used for packaging of foods, liquids and powders, medical devices, agricultural materials, chemicals and other industrial products.
