Aisle ways, Tape type?

[csp1106]

I am putting in place aisle ways into a facility which machines graphite. There is no time for painting due to the downtime involved waiting for the paint to dry. It has been decided that tape will be used, but I am unsure of which is best. The floors are washed very often and I need a tape that will withstand moisture and dirt. I am unsure if a cheaper vinyl tape will work or if I have to go with a more expensive type. Are there any suggestions? Has anyone had this issue before? If there are any suggestions on how to get a perfectly straight line, those would be of help also

We have used this tape in our shop. It seems to hold up pretty well. They also sell an applicator for straight lines.
