One of the two new additives, called Grindsted PGE 909, is designed to provide high cold fog performance in cast and bioriented polypropylene (BOPP) film at 1.5-2.0% letdown ratios. The second new additive, Grindsted PS 426, can be used at low (0.7-1.5%) loading levels for hot fog prevention in both film and thermoforming applications.
Both additives are now available globally and have food approval.
The supplier also offers an anti-fog additive, Grindsted PGE 308, for thin films extruded from metallocene polyethylene or for multi-layer films. Metallocene PE has top-notch heat sealing properties but the as heat seal layer is often only a few microns thick, imparting good anti-fog properties to it can be a tough challenge. Danisco says its additive helps processors do just that.
