摘要:
A method is proposed for manufacturing a cup intended for containing a food beverage. The method includes cutting out at least one sheet of coated paperboard to form a side wall and a bottom and joining the sheets thus cut out by heat-sealing to form the cup. The at least one paperboard sheet is coated on at least the interior side of the cup with a biodegradable varnish according to a coating/spreading technique. In this way, the cup is easy to manufacture, and complies with environmental standards in being easy to recycle and compost, even at home. Thus, the biodegradable varnish does not disturb or pollute the operation of the pulper used in the paper industry.
