Plastomer-mVLDPE Blends for High Performance Heat Sealing Applications, 2003 PLACE Conference & GLOBAL HOT MELT Symposium
Metallocene-catalyzed plastomers are well known for providing superior toughness and excellent heat sealing in
many high performance flexible-packaging films. In these applications plastomers provide a unique combination of
low seal initiation temperatures and high hot-tack strengths. A new family of metallocene-catalyzed polyethylenes
called mVLDPEs also exhibits outstanding toughness and excellent hot-tack performance at somewhat higher SITs
than plastomers. The results of recent blown film studies have demonstrated that performance of
plastomer/mVLDPE blends can approach, and in certain cases surpass, the performance of pure plastomer films.
Selected data from these studies is used to compare the properties of these plastomer/mVLDPE blends to pure
plastomer, mVLDPE, mLLDPE, and EVA films.
