Comparison of EVA and Polyolefin Plastomer as a Blend Component in Various Films Applications, 1997 Polymers, Laminations & Coatings Conference Proceedings

EVAs at various %VA content and AFFINITY* polyolefin plastomers are evaluated as a blend component in various film applications rich in LDPE and LLDPE. High VA EVA resins are partially or completely immiscible with LDPE or LLDPE resins. The EVA resin miscibility with LDPE or LLDPE decreases as the VA content increases. AFFINITY resins are miscible with LDPE or LLDPE resins. The blown films of LDPE/AFFINITY blends gave lower heat seal initiation temperature, and higher hot-tack strength compared to LDPE/EVA blended films. This is due to immiscibility of Elvax 3165 (18% VA) and Elvax 3128 (9% VA) with the LDPE resin. Oriented films of LLDPE/l2% VA EVA blend exhibited higher haze compared to LLDPE/AFFINITY “ B” blended film. Again, this is due to partial immiscibility of 12% VA EVA with LLDPE resins.
