This film is used as backing during embroidery to prevent puckering and slipping of fabric,as this film is 100% removble during garment washing.
When heavy tear away backing is used (in heavy embroidery) the embroidered part stands out with stiff feeling and the strands are visible after wash and causes irritation to skin but PVA film ensures that the finished garment has absolutely no sign of embroidered backing.This film also allows the embroidery to be clear visible and ensures that there is no thread breaking, puckering or damage to emboridary machine.
