  • Patent number: 11279524
    Abstract: The invention relates to a production method of a material, a material and packaging intended mainly for food products. The design of the material used in the packaging machines allows for providing handles in the final packaging without the need for secondary operations. The handles are obtained through either placing a secondary narrower web onto the primary material, wherein the handle constitutes said web, or adjacent holes are cut in the primary material, wherein the handle is formed by the holes separating the primary material. A combination of these two methods or materials is also conceivable. In the area of holes, the primary material is joined with the secondary material, which is either a film or a membrane, wherein the secondary material is larger than the holes and it forms an overlap around them. The materials are joined in the overlap area around the inner circumference of the secondary material.
