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 …
