Definitions

  • the invention relates to a method for producing a bowl, a can, a beaker or other open-topped container with a circumferential flange and a barrier film.

If necessary, they also have only one grease-proof or grease-repellent barrier layer. In this case, the container is often closed by a sealing film, a lid or some other cover that is attached to the flange in a liquid-tight and / or gas-tight manner.
