Abstract
A package for foods is disclosed and comprises a container having a peripheral flange at its mouth. The container is made of or lined with a plastics material so as to provide a plastics surface at the flange. The container is covered by a lid which is heat-sealed to the flange. In order to be able to open the package easily, especially when it is hot, a tear-strip of material extends across at least the flange and is secured to the lid by a heat seal. The tear-strip presents a tab for engagement by the fingers of a user, and, in order to ensure that the lid can be torn effectively by the tear-strip, the bond between the tear-strip and the lid is chosen to be at least as strong as the bond between the lid and the flange.
