Beverage Caps

Borealis AG offers Beverage Cap. This is designed to a unique polypropylene (PP) grade, RE450MO, to produce caps for bottled water. This solution supports the beverage industry"s ambitions to create ever more sophisticated and differentiated user-friendly closures. RE450MO retains the natural taste of the liquid inside while delivering design possibilities not previously available with existing polyethylene (PE) or PP caps. The strength, flexibility, easy integration of colouring and organoleptic properties of the new grade, provides differentiation and recognition for brand owners and attractive, safe, user-friendly packaging for consumers. The material does not contain additives that could taint the natural taste or odour of the bottled product. Retaining the natural taste and odour of a bottled liquid is a top priority. Until recently, the organoleptic properties of PE have made it the only option for unlined caps used for taste sensitive drinks such as water. RE450MO contains ultra-low levels of volatile organic compound (VOC), giving the material high purity. Tests have shown that it fully matches the excellent taste and odour properties of standard PE grades commonly used for beverage caps. From a design perspective, RE450MO offers good flow, low stress whitening and good hinge performance. Its flow flexibility allows versatile designs based on transparency, translucency or colouring. Hinges and closure fittings can withstand the stress of repeated use with minimal discolouration. Borealis worked closely with Seaquist Closures, a leading manufacturer of dispensing closures and systems, to introduce this pioneering development in the market.
