Industries We Supply

K&R Plastics supplies print-grade and engineering plastics across five core industries. The same substrate behaves very differently depending on how it’s printed, formed, and used — so each section below maps the right materials to the processes and applications that define that field, with the gauges, finishes, and print-compatibility data you need to spec a job. Everything is stocked across six U.S. locations for next-business-day freight.

Printers and sign shops lean on our rigid PVC, styrene (HIPS), and PETG for signage and display work; fabricators specify polycarbonate and polyethylene where impact and chemical resistance matter; and packaging converters run APET/RPET for clear, recyclable formed parts. If you’re weighing options, the substrate selection guide and our comparison guides break down where each material wins.

Not sure where your project fits? Browse by application, request a sample to test print and forming behavior, or ask for a quote and a substrate specialist will recommend the right material and gauge.
