BACKGROUND TO RESEARCH PROBLEM
The ZZZ group of companies, with its head office based in RRRRR, GGGGG, develops, manufactures and markets a wide range of high performance biaxially orientated polypropylene films for a wide variety of applications in the food, packaging, label and tobacco industries.
