The Universal Selection Source: Plastics & Elastomers

Milliken
A new generation of Clear PP is available for transparent applications: it provides a cost-competitive, sustainable solution and delivers higher performance and easier processing versus other transparent materials.

Other Performance

Not only does clear polypropylene have the potential to be a less-expensive plastic packaging solution versus PET, due to a combination of raw material cost and lower density. Clear PP may also deliver excellent clarity plus the added benefits of a good stiffness / impact balance and improved moisture/ vapor barrier performance.

Good stiffness / impact balance:
Figure 1 illustrates the optimized balance of relative stiffness vs. impact strength for clear PP in comparison with other transparent materials.

Good moisture / vapor barrier:
Twice better moisture barrier performance: PP has a distinct advantage for barrier performance over PET and many other transparent materials as illustrated in Table 1.

Improved protection against moisture permeation helps protect contents and extend shelf life.

In addition, PP clarified with Millad® NX8000 does not impart taste or odor into products.

As a result, Clear PP provides a viable substitution for higher cost clear materials such as glass and clear plastics which have been traditionally used in injection molded or blow molded applications. These include water bottles, medical devices, appliances, and cosmetic and personal care packaging.
