The invention relates to the field of cups, bowls and containers, particularly beverage cups, and to the production of cups, bowls and containers. According to the invention, the cups, bowls and containers comprise, in a first variant, a first layer (5) made of cellulose hydrate, also known as cellophane, or cellulose hydrate which is coated with a primer material (4). In addition, the cups, bowls and containers can comprise a second layer (3), made of paperboard or fibre/cellulose-starch mix, for example. In a second variant, the cups, bowls and containers according to the invention comprise a first layer made of natural rubber or plant-based wax and a second layer made of cellulose hydrate, paperboard or fibre/cellulose-starch mix. By using exclusively biodegradable materials, the present invention can provide completely biodegradable/compostable cups, bowls and containers. The invention also relates to a method for producing such cups, bowls and containers. In addition, the present invention also comprises the production of lids made of the aforementioned materials and the provision of cups, bowls and containers having such lids.
