About Us – Company Overview

Our Core Values

Since its founding in 1998, ISO Poly Films has remained faithful to its commitment to deliver high-performance films backed by unmatched quality, service, integrity and innovation.

Our team of film industry experts, led by company founder Jon McClure, has built a second-to-none facility in Gray Court, S.C. and established a partnership with Sigma Plastics Group to propel the company and enable us to accelerate our customers’ success. This dedication and know-how has led to ISO Poly’s tremendous success over the years.

It all started in 1995 as an idea and a vision to build a company that paved a new way of doing things in the film industry. With his idea, $1,200 cash and $10,000 of available credit, Jon McClure set out to make a difference.  In late 1997, he secured $600,000 of capital and built ISO Poly Films…and he hasn’t looked back since. By bringing together time-tested and straight-forward business approaches and the top people in the industry, ISO Poly Films has experienced significant growth, including two major expansions and nearly $50 million invested in facility development and advanced manufacturing equipment.
