The Italian company, S.T. Soffiaggio Tecnica Srl's machines are designed to create six-layer fuel tanks, ranging in size from 5-25 liters, on a single line. The equipment features five separate extruders – a 75 mm extruder for the outside and inside high density polyethylene layers, a 90 mm extruder for an inner regrind or recycled layer, a 30 mm extruder for an inner EVOH barrier layer and two 25 mm extruders for the adhesive layers.
Coextrusion is an inexpensive way to manufacture containers that meet increasingly-stringent environmental regulations, said Ernie Hollo, president of Hollo Plastics Equipment, S.T.'s sales representative. The multilayer barrier containers help manufacturers meet regulations aimed at eliminating the permeation of hydrocarbons and other VOCs through the walls of portable fuel containers. Multi-layer systems have allowed Scepter to stay in business and continue making fuel containers. Many companies shut-down or stopped making Jerry cans because they could not afford to meet the new environmental standards, said Deo Bansavatar, maintenance manager at Scepter, in a recent phone interview with the publication Plastics News.
