Stiffness PVC

PVC films surpass polyolefine films in strength, resistance to oils and impermeability to gases and aromatic substances. Stiff PVC films display mold-ability. Their drawbacks are low thermal-, light- and frost-resistance, poor heat-sealing and propensity to agglutination. Soft PVC films are produced from a plasticized polymer. Introduction of a plasticizer into the polymer base adds elasticity, transparency and glitter, improves frost resistance and...
