Abstract: A thermally-sealable multilayer film, for packages which may be resealed after opening, includes an outer layer and a support layer, with a thermally-sealable layer on the side facing the packaged material. A self-adhesive layer made from pressure sensitive adhesive is provided between the support layer and the outer layer. The support layer has weakening lines, which define an opening for the removal of packaged material. For resealing a container, by using the thermally-sealable multilayer film, the user may simply open the defined opening for removal of the contents of the container, by application of an opening force and then reseal the container, by pressing the opened outer layer on to the self-adhesive layer. The above process may be repeated several times, until all the contents of the container are used, whereby the above are protected from possible contamination.
