South Plastic Industry, a leading Asian manufacturer of thermoformed plastic food packaging, has been striving for years to develop a clear, anti-fogging polypropylene (PP) lid for its microwaveable food packaging.<\/p>\n
The aim has been to replace oriented polystyrene (OPS) in this key application, but it wasn\u2019t easy to find a way to get the highly recyclable PP to meet all the necessary performance requirements while also retaining the clarity and non-yellowing aesthetics that are vital to appealing to consumers on the grocery store shelves. Until now.
\nBased in New Taipei City, Taiwan, South Plastic Industry (or SPI) has leveraged its close, five-year working relationship with additives supplier Milliken & Company to finally achieve its goals. Using Milliken\u2019s Millad\u00ae NX\u00ae 8000 clarifier, the two parties have produced an UltraClear\u2122 PP resin that delivers on all the performance promises for ready-meal packaging, while also offering additional processing benefits. SPI also recently began using Milliken\u2019s Hyperform\u00ae HPN\u00ae performance additives in its PP formulations, as well. \u201cBy using Milliken\u2019s additives, we are able to thermoform our products at a lower processing temperature, which allows us to reduce our energy use,\u201d said Mr. Tosho Wang, President of SPI. \u201cAt the same time,\u201d he said, \u201cthese additives allow SPI to produce a thinner PP lid without affecting rigidity, which in turn helps to reduce plastic usage while increasing output.\u201d Saving energy during processing is a major plus for SPI, which runs dozens of thermoforming machines in its Taiwan plant. \u201cMilliken\u2019s additives produce an UltraClear PP that prevents yellowing, reduces oxidation reaction, and extends the shelf life of packaged product,\u201d added Kua Cheng Huat, Milliken Sales Manager for Taiwan.<\/p>\n
