PMV - in-shell lining machine for aluminum closures
Automatic lining machines designed to extrude pellet-form material (e.g. PVCfree, PE, EVA), cut it into single doses, insert them into aluminum screw closures and mould the liner according to a clearly defined profile.
Machine productivity is strongly influenced by the material type and the weight and profile of the liner.
By using PVC FREE raw materials the machine is suitable for moulding liners directly inside the shell of the cap.
Resins allow manufacturers to go beyond the limits of PVC (such as toxicity, smell emissions) offering in this way a new solution for the bottle closures market.
The in-shell technology allows to shape the liners in order to maximize closure perfomances and reduce the compound weight.
