Surface Fracture Prevention in Paperboard Press Forming with Advanced Force Control

Press forming is a three-dimensional forming process used for industrial converting of large quantities of fibre-based composite materials such as barrier coated paperboard. The technology enables the production of plate and tray packages of such high quality that it is possible to lid seal them to create a gas-tight package. The method is primarily based on the controlled folding and compression of materials using high forming forces and elevated tool temperatures.
