Milliken demonstrated why NX™ UltraClear PP is the optimal, cost- effective option to help brand owners address the growing packaging trends for both resource efficiency and attention-grabbing appeal. “NX UltraClear PP, which is polypropyle- ne clarified with Milliken’s Millad ® NX™ 8000, is the ideal material to bring ex- ceptional clarity, aesthetics, light- weighting and increased sustainability to a variety of commercial packaging appli- cations,” according to Sami T.K. Palani- sami, Milliken Commercial Manager – EMEA. “It offers the clarity of materials such as PET, while delivering specific be- nefits for different processes”. Brand owners benefit from thermo- formed NX UltraClear PP : When it comes to thermoformed and foldable packaging, NX UltraClear PP delivers a vast range of property and performance benefits to converters and brand owners, allowing the resin to offer an all- round packaging solution. These include: • Glass-like transparency : For thermo- forming and sheet packaging, NX Ultra- Clear PP rivals the glass-like clarity of com- monly used resins such as A-PET and poly- styrene, while also offering a glossier ap- pearance than that normally associated with standard, nucleated polypropylene. • Lighter weight – NX UltraClear PP has a significantly lower density than other plastic material options, reducing the weight of a thermoformed part. PP’s density of 0,9kg/m³ compared to PET’s density of 1,37kg/m³ allows converters to produce significantly more trays per kilo of material. Using less material also can help to reduce eco-tax contributions. • Stiffness & impact strength – For NX UltraClear PP to achieve the same stiffness as A-PET, the PP sheet typically is 15 to 20% thicker compared to the vir- gin A-PET sheet. But opting for a ribbed or improved design often can obviate the need for those thicker walls. NX Ultra- Clear PP’s lower density yields products that weigh much less than correspond- ing PET applications yet with equal stiff- ness. • Sealing effectiveness – Polypropyle- ne is known to be very robust and easy to seal. Standard PP sealant films still seal well even when residue is left on tray ed- ges and exteriors during filling. A mono- material PP tray & PP film solution offers the advantage of a 100% recyclable sys- tem that does not require the use of an adhesive. • Hot filling, retort & microwave ability – NX UltraClear PP is a great choice for any thermoformed cup or tray application where higher temperatures are concerned. Its excellent heat resis- tance and good cold-temperature per- formance combine to make it suitable for hot fill and microwaveable applicati- ons, while also enabling the “fridge to microwave” concept. • Recycling & sustainability – Poly- propylene offers a compelling circular- economy story in that a strong market exists for recycled PP in a variety of end products. As a material, PP consumes the least amount of energy during producti- on and produces the fewest carbon di- oxide emissions. Its lower density means that adopting the resin also reduces the absolute amount of waste. Thermofor- med NX UltraClear PP applications also are straightforward to recycle because their mono-material concept. Enabling complex, easy-empty blow molded bottles : NX UltraClear PP al- lows brand owners to develop light- weight bottles with integrated handles and complex, eye-catching designs. These extrusion blow molded (EBM) bottles are also easier and faster to emp- ty than other options. Polypropylene ma- de using Milliken’s Millad NX 8000E ad- ditive offers the lowest density and lower weight compared to glass and all alter- native EBM plastics. For example, clear handleware bottles made using NX UltraClear PP have a density of 0.9 g/cc compared to PET’s 1.35 g/cc, yet deliver the same clarity level. At interpack, visi- tors can experience first-hand the easy- empty feature of such bottles, which re- duces product waste. Package your products in PET with confidence with ClearShield UV ab- sorber : Milliken’s advances are not limi- ted to polypropylene. The company also brings real value to PET packaging via its ClearShield ® UV absorber. This technolo- gy effectively protects UV-sensitive packed contents from degradation while maintaining the clarity and transparency of PET. This is vital, since brand owners are res- ponding to consumer demands by using more natural ingredients in everything from solid or liquid food and vitamins, to home- and personal-care products. But exposure to UV light can degrade such ingredients, and negatively impact the consistency of such packages’ contents – be it in appearance, fragrance, color, fla- vor or nutrient value. ClearShield offers an alternative, simpler way to provide UV protection. By incor- porating the UV absorber into the PET packaging itself, this technology allows brand owners to remove the often high loadings of UV additives that until now they have had to include in the formula- tions of the packaged contents them- selves. This can reduce cost by simplify- ing the formulation process and reduc- ing the amount of UV additive needed. ClearShield-modified PET enables the use of more environmentally friendly contents, and serves to extend the shelf life of packaged materials, which in turn helps to reduce waste and protect brand image.
