...verage annual per capita ice cream consumption in Western Europe is about 10kg. Differentiation among the premium brands via packaging is increasingly becoming a key to success. Custom products such as Borpact SG930MO (Borealis) or Clyrell EC140R (Basell) captivate via their outstanding transparency, very good impact strength under deep-freeze conditions and exceptional processability (Fig. 3). Borpact SG321MO is softer, and thus well-suited for use, for instance, in covers under deep-freeze tem...

... needed. Until recently, the polyolefins industry was often confronted with the dilemma to opt either for impact performance giving up transparency or to focus on the aesthetic aspects of the final item sacrificing toughness. With the launch of the Clyrell product family, Basell has added a new dimension of performance to the polyolefins market. The material's unique combination of outstanding impact performance with excellent transparency is expanding the technological frontiers into severa...

...nce and surface quality. The further expansion of the PP properties window can be achieved by various technical means, from catalysts and built-in co-monomers through to modification and processing [6]. One example is Basell’s Clyrell product family, whose particular focus in combining transparency, sealing capacity and low-temperature performance can be tailored quite differently depending on the specific application. Borealis offers the same versatility in its Borpact products. Borpact SE920MO...

...stack (Fig. 2), a calendering belt (Fig. 3) and a water bath (Fig. 4) are compared with each other. Three different polypropylene (PP) grades were processed to this end (homopolymers Moplen HP 540J and Moplen Adstif HA 748 C and the random copolymer Clyrell 7173 XCP, manufacturer: Basell), and material specimens were assessed in respect of their thermal, mechanical and optical properties. The cooling processes for the polishing stack and calendering belt technology were also compared with each o...

... low-temperature stability (down to -40°C). It is dishwasher-safe and withstands microwave temperatures. The opaque material will find its first application for packaging of ice cream in the USA. The transparent polypropylenes Clyrell RC 514L, Stretchene RP 1685 and Stretchene RP 1903 from Basell possess a unique combination of optical and mechanical properties such as transparency, gloss and stiffness. Moreover, compared to PET, packaging made from these materials can be hot-filled, pasteurized...

...higher temperature resistance compared with PET, which permits the largely germ-free filling of hot liquids. PET grades with a comparable temperature resistance are more expensive. One example of a current innovation in this field is Clyrell RC 514 L from Basell: a polypropylene offering not only exceptional transparency but also good stiffness and ease of processing (Fig. 3). This material can thus also be used for the form-fill-seal process which has so far been the preserve of PS and (with li...

...or customers who need to differentiate themselves in their markets, we offer highly innovative specialty products. These products are particularly valuable in key emerging markets. For example, our innovative PP Stretchene (Fig. 3) and Clyrell resins can be used instead of conventional materials such as PET and glass. Our Purell resins product portfolio (Fig. 4) is aimed at medical and pharmaceutical customers in particular. And for the fast-growing markets for drinking water pipes, we have deve...

...P random copolymers, such as Moplen RP340N or RP348R (manufacturer: LyondellBasell); both have excellent transparency and provide good organoleptic properties and good flowability. In applications requiring special low-temperature toughness, Clyrell EC340R has a proven track record. This is a specially developed transparent PP copolymer that also has low stress whitening and high surface quality. This property combination is now used for developing new closure types that could not be rea...
