The scientists found that the addition of one or more discrete layers of amorphous COC to LLDPE-based blown film significantly reduced total haze, including its internal and especially surface-haze components.

The Topas team studied glass transition temperature, COC modification and blow-up ratio to quantify how COC influences the performance of several key blown film properties in three-layer (90-micron thick) and five-layer (152-micron thick) structures. “We found that by splitting COC into at least two layers in five-layer structures, further significant property enhancements are possible without changing COC content,” explained Paul Tatarka, Market Development Manager for Topas Advanced Polymers at this year’s ANTEC. Using design of experiment (DOE) methods, Topas researchers demonstrated that COC provides greater than expected toughness, strength, stiffness and appearance in multi-layer packaging structures made of LLDPE.

A study conducted by Topas Advanced Polymers (Florence, KY) revealed that discrete layers of cyclic olefin copolymer (COC) provide significant performance enhancements in three- and five-layer packaging film structures made of linear low-density polyethylene (LLDPE).
