Ampacet Corp. has debuted a high-efficiency antioxidant masterbatch that protects reprocessed and recycled polyolefins from degradation during processing.
The new masterbatch allows blown and cast film producers to use more recycled content without adversely affecting aesthetic and physical properties, the company said. It is especially useful in clear packaging films where cost savings are driving the use of more recycled resin, but where gels are not tolerated.
The product is also useful in repelletizing operations where it restores thermo-oxidative stability, allowing recycled resins to perform more like virgin resin, according to the company. It is approved for food-contact uses.
Let-down ratios of 0.5 percent to 1 percent are typical for the masterbatch, said Tarrytown, N.Y.-based Ampacet. With blown film, a 0.5 percent level reduces gels and allows the use of up to 10 percent scrap. In one case, a 1 percent level gave a cast film processor the ability to boost the use of repelletized material from less than 5 percent to greater than 15 percent in a critical application, according to Ampacet.
