Spanish energy and petrochemicals company Repsol (Madrid; www.repsol.com) has announced an expansion of its UltraClean range of polyolefins for single-material, 100% recyclable flexible packaging.

New grades include HDPE UltraClean 110, HDPE UltraClean 120, mLLDPE UltraClean 210, mLLDPE UltraClean 220, and EBA (ethylene butyl acrylate) UltraClean 310, the company said. 

The polymers are said to boost the performance of final products versus alternative materials in the market with improved processability and higher stretch ratios of up to 40%, with the latter suiting the materials for applications with maximum orientation and differentiated mechanical properties, Repsol said. 

According to the supplier, the polymers are designed to promote sustainable eco-design, in that they replace multi-material structures that cannot fully be recovered due to the difficulty in separating different materials. The range is available in circular, bio, and bio-circular versions, according to the supplier.
