摘要： A multi-layered packing material in the form of a web for use in constructing blanks to be erected into finished packaging containers comprises a relatively stiff base layer made of paper, cardboard or foamed plastic coated preferably on both sides with a layer of thermoplastic material, e.g. polyethylene. The laminated packing material may also include aluminum foil to establish a gas-proof barrier. At least one of the edges of the laminated packing material is provided with a narrow edge zone of a heat-activatable bonding agent of the same thickness as the web such as a mixture of solid hydrocarbons which is mechanically stable but elastic at normal temperature and has a relatively low melting temperature range. The edge zone consisting of the heat-activatable bonding agent is utilized in establishing a butt type joint between it and an adjacent panel or other planar part of the container when erected.
