"Polytama's current priority is to ensure that every product not only performs exceptionally but also provides added value to customers—particularly in energy efficiency and sustainability," said Ferry Tanumihardja, Director of PT Polytama Propindo. "Polytama continues to deliver relevant solutions for the industry by adopting the latest technologies, allowing our products to achieve higher quality and processing efficiency."

Masplene® MAS9475 is ideal for applications such as food containers and housewares, where clarity, gloss, and mechanical performance are essential. The resin complies with major food safety and packaging regulations and Halal certification standards, supporting safe use in food contact applications.

"Quality and innovation are inseparable in Polytama's journey as a leading polypropylene resin producer in Indonesia," said Ferry. "Improving product quality is not merely about physical performance, but also about helping customers reduce operational costs, conserve energy, and support the transition toward improved industry practices."

The UL ECV is a third-party testing program provided by UL Solutions, a global leader in applied sciences. A UL ECV label affirms that a product's claims have been independently verified by UL, which can help increase consumer confidence and overall brand credibility. Brand owners using PP resins enhanced with Milliken Hyperform® HPN technology can display a UL ECV label on their injection-molded parts.

"Milliken is proud to collaborate with Polytama to bring Masplene® MAS9475 to the Indonesian market," said Daniel Tanzil, country manager for Milliken's plastic additives business. "This launch demonstrates our shared commitment to delivering innovative solutions that help customers achieve greater efficiency, product quality, and confidence in their manufacturing processes."
