Extrusion: Single-layer die heads benefit from design

This equipment maker says that thanks to the positive results obtained with its multilayer blown-film heads in the EXPH series, it has applied the same construction concept to the company’s monolayer film lines in the MOEX series. The technology allows a cut-off of the dimensions with the result of a better and easier line control and management, it says. The side feeding involves a cut-off of the inside volumes with the subsequent reduction of the melt residence time. The special geometry permits the possibility of having larger air channels and therefore a stronger internal bubble cooling efficiency. The four models in the CF series feature the company’s standard single-layer stationary head with central feeding and spiral distribution. The die range is from 300-2600 mm. This largest size can be used for agricultural film processing. The CFR family is an oscillating version of the CF series. Luigi Bandera SpA, Busto Arsizio, Italy; +39 0331 389111; www.lbandera.com
