Laminate tubes are made from webs that comprise at least five different layers including the barrier layer. The two longitudinal edges of the laminate are welded together to form the tube body, which is then joined to the tube shoulder with its closure to give a reliable and impermeable seal.
Depending on the product and contents, laminate tubes can have a barrier layer of aluminium, plastic or ceramic and – in the case of transparent laminates – a barrier of polyester. The so-called Polyfoil tube is a specific type of laminate tube in which a plastic layer is extruded on top of the laminate.
Plain white laminate tubes combine the beneficial properties of the different materials: excellent barrier effect to protect the contents.
