Multi-Layer Co-Extrusion

Agri-Industrial Plastics Company was the first industrial blow molder in North America to invest in continuous co-extrusion (COEX) multi-layer blow molding technology to produce non-automotive fuel tanks. In 2005, we installed a new Kautex (COEX) multi-layer blow molding machine. This multi-layer blow molding technology that was originally developed for the auto industry is used to create a six-layer structure with a separate barrier layer to reduce fuel vapor permeation. Each layer is extruded individually through separate extruders that converge into a single extrusion head. Six-layer continuous co-extrusion blow molding technology is considered the gold standard in fuel vapor emissions control in the market today. The new Kautex machine offers proven technology and is capable of producing tanks ranging in size from 3 to 50 gallons, depending upon tank geometry.

In November 2008 we announced our planned capacity expansion of our multi-layer co-extrusion offering as we placed an order for the construction of a second machine. This additional machine will be production-ready by the first quarter of 2010, ahead of EPA deadlines for compliance with emissions standards affecting the marine, lawn & garden and agricultural industries. This most recent investment in multi-layer continuous co-extrusion technology will position Agri-Industrial Plastics Company to serve customers impacted by the new EPA fuel vapor emissions standards for agricultural equipment, ATVs, snowmobiles, personal watercraft, marine, motorcycles and lawn and garden equipment.
