Paper backing is highly absorbent and transports water to show indications
	
Acrylic adhesive allows for a very high bond strength to most surfaces including low surface energy plastics such as polypropylene and powder coatings
	
Total construction is rotary die cuttable with no film top layer
	
Tape is thinner to enable slim electronics device design
