Paper forming


Huhtamaki S.A uses a wide range of paperboard forming technologies to manufacture innovative hot and cold beverage cups, paper buckets and food containers to meet customer and consumer requirements around the world. Materials used for paperboard packaging are always of high quality to fulfill the requirements of the foodservice customers. Most of our paperboard is currently based on wood fiber from the Programme for the Endorsement of Forest Certification (PEFC) or Forest Stewardship Council (FSC) certified sustainably managed sources.


Paper cups use Solid Bleached Sulphate (SBS) paperboard. Considered as a premium grade for packaging when purity, good appearance and runnability of the packaging material are required. The board is coated with thin layers of polymer compounds, on one side or on both sides, depending on the use. Standard paper cups have PE coating either on inside (hot cups) or on both sides (cold cups). The key feature of PE-coating is humidity protection. It is typically used in drinking cups, frozen food, ice cream and yoghurt containers. Paperboard is typically printed with either state of art flexo or offset printing lines and can feature customer name, logo or promotional message. Custom printing is an excellent method of communicating to customers and enhancing the brand awareness.  

 
Plastic forming


Huhtamaki utilizes predominantly thermoforming process in plastic production. The thermoforming process forms products out of extruded sheet. Through the in-line thermoforming process the sheet is extruded directly before feeding into the thermoformer. Any waste is grinded directly in a downstream granulator and fed back as re-grind material. Thermoformed plastic cups can be printed with dry offset printing. Thermoformed plastic packaging is manufactured from polymers such as Polypropylene (PP) and recycled or virgin Polystyrene (PS).
