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.
A method for manufacturing a packaging material, wherein the material comprises at least one primary web wound on a roll, and wherein holes are cut in the web onto which fragments of a secondary material are arranged, the method comprising cutting at least two holes in the primary material and the pieces of the secondary material with a surface and shape greater than a sum of such adjacent holes and the primary material separating them are arranged onto the hole area so that an overlap is formed around them and the primary material separating them, after which the materials are joined in the overlap area only along the inner circumference of the piece of the secondary material.
A packaging material comprising having at least one substrate of a primary material wherein said primary material can receive fragments of a secondary material.
A method for manufacturing a packaging material, wherein the material is at least one primary web wound on a roll, comprising joining onto at least one web of the primary material wound off a roll, at least one secondary web with a width smaller than the width of the primary web, which secondary web ultimately constitutes a handle of the finished packaging, after which both webs are joined in the joint areas of the handles of finished packagings with the primary material.
