Paper cores are tubes produced from coreboard by spiral or parallel winding processes, normally used as the base around which various products (e.g. paper, film, adhesive tape, fabric, and yarn) are wound. There are clear limitations to demand-side substitutability, although some cores may be suitable for several applications. The market investigation confirmed that especially for the production of high-value products, such as high-end paper mill cores (PMC) and yarn carriers, specific know-how and machinery are needed. Supply-side substitutability exists to a sufficient degree between the less sophisticated cores. However, the coating of cores requires some additional investments.
