Label Construction Issues

Q: How should converters select a cost-effective polypropylene label construction?

A: Converters must avoid over-engineering or under-engineering a polypropylene label construction so that material cost is balanced with performance. During the selection process, converters must consider gauge, opacity, flexibility, expected UV durability, and top coating needs for receptivity to the print process to be used. Thicker gauge, higher opacity and higher UV resistance all add cost.
