Apparatus comprising a first sealing member and a second sealing member movable relative to said first member, the sealing members (2) serving to seal a container sealing fin (20) therebetween, the first sealing member (2) including an inductor device (6), the inductor device being embedded in a magnetic field concentrator. Also disclosed is a method comprising providing a laminate comprised of a paperboard layer, an electrically conductive layer and a thermoplastics layer, shaping the laminate into a partially formed gable-top container having a top sealing fin region so as to bring a multiplicity of layers of the thermoplastics layer into a face- to-face relationship with each other in said region, and sealing the multiplicity of layers face-to-face with each other using the first and second sealing members, wherein the sealing of the multiplicity of layers is performed in a single induction sealing operation. |
