Resilience in Cartonboard
Usually this type of product is packed in plastic cups with a plastic lid. The challenge was to develop a paper cup that could be hot filled (80 °C), be stored chilled, provide 42 days shelf-life – and be microwaveable! These requirements were fulfilled through a customised coating, a flat rim with wide sealing area (for the membrane) and a strip to protect the inner side-seam. The paper-content is still 88%. The sealing membrane is protected by a paper-lid.
