Abstract

A method for producing a shell lined with a film, in particular a shell for receiving food is provided, the method having the steps of: erecting an unfolded sheet of a paper fiber-based material in order to form a shell comprising a base, a lateral wall which has an upper edge and which consists of at least two lateral wall parts, wherein laterally adjacent lateral wall parts are designed to overlap with one another, and a collar which runs circumferentially on the upper edge and extends outwards therefrom and which defines an access opening, positioning the film above the access opening, heating the film, fixing the film on the collar, and supplying compressed air to the film side facing away from the shell in order to blow the film into the access opening in order to laminate the base and the lateral wall with the film.

Abstract

The invention relates to a method for producing a shell (4) lined with a film (24), in particular a shell (4) for receiving food, having the steps of: erecting an unfolded sheet of a paper fiber-based material in order to form a shell (4) comprising a base (10), a lateral wall (14) which has an upper edge (12) and which consists of at least two lateral wall parts (16a, 16b), wherein laterally adjacent lateral wall parts (16a, 16b) are designed to overlap with one another, and a collar (18) which runs circumferentially on the upper edge (12) and extends outwards therefrom and which defines an access opening (20), positioning the film (24) above the access opening (20), heating the film (24), fixing the film (24) on the collar (18), and supplying compressed air (6) to the film (24) side (34) facing away from the shell (4) in order to blow the film (24) into the access opening (20) in order to laminate the base (10) and the lateral wall (14) with the film (24).
