The present invention relates a method for the production of an adhesive wherein said method comprise the following steps: providing a suspension comprising starch, swelling the starch by alkali or temperature treatment or by cooking the starch suspension to form a starch suspension, providing a suspension comprising microfibrillated cellulose which suspension has a solid content above 10%-by weight, adding the suspension comprising microfibrillated cellulose to the suspension comprising starch either before or during the swelling or the cooking of the starch or to the formed starch suspension to produce the adhesive. The invention further relates to a corrugated board and an adhesive.

An egg carton and method and apparatus for forming an egg carton. A main body of the egg carton may be made of a single sheet of material and folded or otherwise bent to form the majority of the carton's interior space. Partition walls may be engaged with slots formed in the main body to define separate storage areas of the interior space as well as help hold the main body in the desired configuration. Hooks on the sides of the partition walls may engage with openings in the main body to secure the main body to the partition walls.
