Milliken's Ultra Clear PP packaging at RosUpack 2015
Visitors can experience the low weight advantage and all-round benefits of Ultra Clear PP clarified with Milliken's pioneering Millad NX 8000 series for packaging. They can also look in-depth at opportunities to enhance Ultra Clear PP with ClearTint Colorants offering superior deep rich shades not yet available with traditional pigment colors.
For thermoforming and sheet packaging, Ultra Clear PP clarified Millad NX 8000 sets a new clarity standard for PP that is comparable to glass-clear materials. It gives PP a clarity boost that overcomes the traditional undesirable milky appearance to create highly-attractive transparency similar to PET for applications such as meat trays, clamshell containers and lids. Ultra Clear PP also offers important performance benefits such as mono-material packaging, easy seal, chemical resistance, impact resistance and heat resistance. The material’s excellent heat resistance further extends application opportunities by enabling microwaveability and hot fill capability.
Proven statistics support Ultra Clear PP's productivity improvements, energy savings, low carbon footprint and cost-efficiency compared to alternative plastics. It offers a 17.8% weight saving compared to PET based food trays, with possibilities to produce 70 trays from 1kg of PP compared with 57 trays from 1kg of PET.
Injection molders can also take advantage of the exceptional aesthetics, productivity gains and energy-saving benefits of Ultra Clear PP clarified with Millad NX 8000. For example, to produce thin wall packaging containers. Use of the additive allows conversion temperatures to be lowered, particularly in injection molding, leading to less energy use and accompanying CO₂ emission reductions. Numerous industrial test data indicate that use of Millad NX 8000 can lower required processing temperatures from 235°C to 190°C, resulting in cycle time reductions of up to 10%, energy savings between 8 and 12%, and associated CO₂ emissions reductions.
Using Milliken's ClearTint innovations, converters and designers can offer the deep rich shades currently popular with consumers and meet the trend toward packaging that extends shelf life. ClearTint colors offer the clearest and brightest colors for transparent polyolefin while maintaining the glass clarity look of Millad NX 8000 clarified PP. In addition, Milliken's ClearTint CUV is a transparent UV absorber specifically designed for use in PP. This additive can be used to inhibit UV light transmission in injection molding, thermoforming and blow molding.
"Ultra Clear PP offers a host of value adding benefits to the packaging industry and we are looking forward to bringing these to the forefront at RosUpack 2015. The use of ClearTint in PP clarified with the Millad NX 8000 series gives an unprecedented boost to color possibilities and product protection in one, taking these advantages a step further," comments Dariusz Lukaszewski, Regional Manager CEE, Milliken.
