Milliken will display UltraClear PP for thermoformed food packaging at FachPack 2015 in Nurnberg, Germany, from September 29 – October 1.
The company will showcase applications demonstrating the full potential of UltraClear PP alongside ultra violet (UV) protection solutions for polyolefins and polyethylene terephthalate (PET) bottles.
Visitors can see how UltraClear PP clarified with Milliken’s Millad NX 8000 series, which is comparable to glass-clear materials.
Millad NX 8000 gives polypropylen (PP) a clarity boost that overcomes the traditional undesirable milky appearance of PP in thermoforming, thereby creating highly-attractive transparency similar to PET for sheet and thermoformed applications such as meat trays, clamshell containers and lids.
UltraClear 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.
At-booth samples will demonstrate its ability to offer a 17.8% weight saving compared to PET based food trays, with possibilities to produce 70 trays from 1 kg of PP compared with 57 trays from 1 kg of PET.
“As a mono-material solution UltraClear PP can be recycled easily, unlike multi-material or multi-layered PET alternatives,” says Sami T.K. Palanisami, marketing & sales manager plastic additives.
At the show, the company will also exhibit:
– ClearTint CUV, a transparent ultra voilet (UV) absorber for use in polyolefins, which can be used to inhibit UV light transmission in injection molding, thermoforming and blow molding, and
– ClearShield Colorless UV Absorbers as an UV protection performance standard for PET that extends the shelf life of packaged materials.
It is approved for food contact applications by the European Food Safety Authority.
ClearShield also overcomes the deficiencies of traditional technologies, including unwanted color, migration, bloom and plate-out.
