Paper Cups for Hot & Cold Drinks

Traditionally beverage cups are produced on a single or double-sided PE coated paper. After printing and potentially varnishing, the rolls are either converted in single cups or a reel of single cups. This is driven by the type of cup making machines that are being used (sheet-fed or roll-fed). The single coated paper is used for hot drinks and the double side coated for cold drinks (after serving, condense could arise on the outside surface affecting the structural strength of the cup when there would be no outside coating). The PE coats allows for the cup to be formed and sealed in the required shape. Conventionally these are mainly printed with web-fed flexo.

Kotkamills has created a plastic-free material for cups, ISLA® Duo cupstock. This plastic-free and easily recyclable cupstock is based on water-based dispersion barrier. Barrier prevents the liquids from immerging into the board or leaking and it is applicated with on-line coating technology. Being plastic free, ISLA® Duo can be recycled with normal paper and board waste. This way the recycling process is made as easy as possible, enabling easy accessibility for both the consumer and the retailer to promote the fibre re-usage for other fibre based products. ISLA® Duo is digitally printable on Xeikon 3500 range using dry toner technology with excellent printability, productivity and toner adhesion.
