SAO PAULO (ICIS)--Milliken Chemical has developed a polypropylene (PP) resin in partnership with Braskem that offers an option to polyethylene terephthalate (PET) extrusion blowmoulders, Milliken’s market development manager said on Wednesday.
The technology, using a fourth-generation Milliken additive, results in a product with higher transparency and gloss than previous PP formulations, allowing the resin to better compete with PET in cosmetic packaging applications, Milliken's Claudia Kaari Sevo said on the sidelines of the Brasilplast trade fair and conference
With the Milliken additive, production costs can be controlled by thin gauging of the PP container to reduce its weight. The resin also allows for a shorter production cycle in the manufacture of containers, further contributing to cost savings, according to Kaari Sevo.
The clarified PP can be used in packaging for direct contact with food, and presents a good balance between rigidity and impact resistance. The resin also has good chemical resistance and thermal properties, and is recyclable, according to Milliken.
Brasilplast, which runs 9-13 May, is a major event for the plastics industry in ?xml:namespace>
