Multi-Layer Co-Extrusion

Multi-layer co-extrusion blow molding is a proven technology developed over 20 years ago for the automotive industry.

The process creates a six-layer tank wall structure with an EVOH layer to minimize fuel vapor permeation.  Multi-layer construction ensures barrier performance for the service life of your vehicle.

Our continued investment in multi-layer co-extrusion capacity has positioned Agri-Industrial as the leading supplier to OEM’s in the turf equipment, power sports and marine industries.

Today we operate six COEX machines producing tanks from 3 to 53 US gallon liquid fuel capacity.
