CV77518 resin is a polyethylene plastomer designed for blown and cast film extrusion that contains no slip and no antiblock additives. Films produced with this resin exhibit a very low seal initiation temperature with a broad hot tack window. Other features of this resin include higher stiffness, high melting point, and ease of processing for narrow die gaps.

Application/Uses:
Blown film
Cast film
