发明名称 SEALABLE PACKAGE AND PRODUCTION THEREOF
摘要 There is provided a method of producing a package (403, 503) adapted to be sealed, comprising: a) arranging a sheet (400, 500) of stretchable paper on a cavity (401, 501) having a circumferential rim such that the sheet contacts the rim of the cavity; b) applying a pressure to the sheet such that a nip (404, 504) is obtained at the rim of the cavity; c) applying a force to the sheet, wherein the pressure of b) and the force of c) are selected such that the sheet partly slides into the cavity and partly extends within the cavity to form a package having a body portion and a rim portion formed at the nip; and d) coating a surface of the rim portion to form a surface for gas-tight sealing. A package as well as a use thereof are also provided.
