▎ 摘　　要

NOVELTY - A packaging material (100) comprises one or more layers of a heat sealable material (106) laminated to a core layer (104), and at least one carbon-based layer (112) provided to form a workpiece (60) of an associated sealing system. USE - Packaging material for forming individual liquid food packaging containers (claimed). ADVANTAGE - The carbon-based layer effectively assist in protecting the content of the packaging container made of the packaging material from outside environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the material (100), which involves laminating one or more layers of the material (106) to the layer (104), and applying at least one layer (112) to the material (100); (2) packing container, which comprises a main body formed by the material (100), and having at least one heat seal (transversal seal) arranged at a sealing area, where the material comprises a layer (112) arranged at the sealing area; and (3) manufacture of packing container, which involves heat sealing the material (100) by activating an electromagnetic device such that heat is generated in the workpiece. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the packaging material.
