Their high mechanical resistance and special surface properties (including significantly decreased friction) enable automated processing to be performed optimally at the customer's premises.

Our multi-layer flexible laminates PUCARO Press-span, PUCARO Triflexil®, and PUCARO Ecoflexil®, made from pressboard, polyester and polyamide films, polyester non-woven material or aramide papers, fulfill the requirements of automated processing.
