Closure, houseware grades offer productivity, property enhancements

Borouge chose the recent Chinaplas show in Shanghai to debut two new grades for the packaging industry: a random polypropylene (PP) which provides absolute clarity in houseware applications and a high-throughput, high-density polyethylene (HDPE) grade for closure applications

Random polymerization technology delivers ‘absolute clarity’ in RG568MO for houseware.

Grade RG568MO for houseware is said to provides absolute clarity through deployment of leverage Borouge’s in-house random technology and Borouge Nucleation Technology (BNT) that accelerate the melt-to-solidication rate. “Houseware molded from the grade has a desirable bluish tinge to it versus the yellowish tone of the previous grade,” says Michael Alan Pell, Vice President, Innovation at Borouge.

Borpure Grade MB7581 for closures, meanwhile, is a grade with an MFR of four that processes like a material with MFR of 10 according to Pell, who also noted the migration towards HDPE, particularly the bimodal type, for lightweight closures on account of its superior stress crack properties. “We’ve seen a weight reduction from 2. 4 g to 1.95 g over the past ten years, which represents a 20% saving. And for carbonated soft drinks you can go as far as 1.8 g.”

The material was running at Chinaplas on a compression molding machine operating at the stand of Italian machinery supplier Sacmi.
