Thermoplastic Extrusion


Through innovation and acquisition, Sinclair & Rush has grown to be one of the largest extruders of clear plastic tubing for packaging applications in the world. Our expertise in clear materials has helped us earn this position, but it is our extensive product line of both tubes and closures along with our secondary processing capabilities that truly makes us unique.

What is Thermoplastic Extrusion?

Thermoplastic extrusion is a relatively standard process used to manufacture all types of plastic tubing. In its most basic form, the process involves heating plastic resin, pushing it through an extrusion die, curing it, cooling it, and cutting it to length. Sinclair & Rush takes the process to the next level by using innovative designs, materials and technologies developed specifically for the packaging industry.

Business Units Supported

As a worldwide leader in visible packaging, VisiPak is the primary business unit supported by our thermoplastic extrusion operations. While the process can be used to manufacture other products, it is our intense focus on developing clear plastic packaging solutions that truly differentiates Sinclair & Rush from other plastic extruders.


To effectively serve our clients and support our global business, thermoplastic extrusion operations are strategically located throughout the world.


Marketed by the VisiPak business unit, our thermoplastic extrusion operations throughout the world produce an unmatched selection of stock, standard, and customized clear packaging tubes. The line extends well beyond round, square, rectangle, oval, and triangle plastic tubes, to include our innovative sealed bottom containers and hang tubes. By complementing our extruded products with our line of injection molded and dip molded caps and closures, Sinclair & Rush’s capability to design complete packaging solutions is virtually unmatched.
