Abstract
The tubular water quenched (TWQ) process is commonly used to convert polypropylene (PP) into unoriented films in Asian, Mideast and other markets. The key requirements for TWQ films are (1) good optics (e.g. low haze) and (2) good openability. This study reports the effects of antiblock and slip additives in UNIPOL® PP homopolymer on these key film properties.
