Corrugated polypropylene for packaging such as for example, interlayers, boxes, trays and interior fitments. Wellplast® is the trademark for our high quality corrugated plastic material. It is produced in sheets by extrusion from 100% PP-plastic (virgin or regenerated). It is produced in many thicknesses between 2 and 10mm. It is very light weight and very durable, why it is specifically suitable for return systems. White is our standard colour, but it can be produced in other colours. Additives can be added to achieve other characteristics (see in table below). Except from corrugated plastic common names are twin wall sheets and fluted plastic sheets.
