Metallocene VS EVA

In it’s day, ethylene vinyl acetate ( EVA / PEVA ) was a game changer.  It enhances physical properties and sealability.   When added to homopolymer polyethylene in small amounts (1 to 3%) it improves the clarity.  When added in higher percentages (4 to 6%) it further enhances sealabilty and improves cold stress crack resistance.  At the 4 to […]
