Selection of cleaning methods for coextrusion dies

摘要

Expensive and delicate polymer coextrusion blown film dies deserve to be cleaned non-destructively. This paper will help plant operators and maintenance staff select from the variety of available cleaning techniques and apparatus. The best cleaning methods for a given operation may be swayed by factors fixed by the polymer process being run, or factors of finance or plant location. In the long run, the "best" cleaning strategy is the one which supports the most production with the lowest total investment over time.
