Key Characteristics and Main End Uses
Northstar BioHot is a sustainable choice; it is produced from renewable paper from well-managed forests and coated with biopolymer. This product is 100% compostable in industrial composting and can be collected together with food waste in most collecting schemes. Northstar BioHot is food-safe, taint and odour neutral and suitable for hot food and beverages. It is also very cost-effective due to its good runability during conversion, minimising breakages and disruptions in production. The board’s stiffness entails a light yet functional cup, making it an economical choice
Technical Specifications
For optimal printing results, the moisture proof wrapping should not be removed until the board has reached the temperature of the press room.

The product properties, according to the specifications, are guaranteed for 12 months after the production date. In order to ensure product safety, the product must be well wrapped and stored indoors, sheltered from rain and snow. The recommended storage conditions are 50-55% relative humidity and 20-23° C.
Printing and Finishing Techniques
The product can be used for different printing techniques such as offset, flexo and digital printing. It is important to check possible limitations of the printing and converting equipment and ensure that the basis weight of the board fits the tooling to be used. Since a wide variety of digital printing equipment is available in the market, it is important that a new commercial digital print job is always preceded by a trial run, including all required printing and converting process phases.
