ENVASE PLEGADO Y METODO DE FABRICACION DE DICHO ENVASE

Método para fabricar un envase, preferentemente para productos alimenticios y no alimenticios, incluyendo comestibles y bebidas o similares, comprendiendo dicho envase como mínimo un fondo (4) y como mínimo un lateral (14), estando formado dicho envase por al menos una hoja, caracterizado porque la hoja comprende como mínimo una capa (3) de una sustancia plástica a la que se ha añadido una determinada cantidad de material inorgánico pulverizado, y porque la fabricación del envase comprende al menos una combinación de como mínimo los siguiente procesos: a) troquelar al menos parcialmente la hoja en piezas troqueladas (10) a partir de una alimentación por rollo o por hoja. b) plegar al menos un fondo (4) y al menos un lateral (14) c) soldar al menos un fondo (4) y al menos un lateral (14) d) formar al menos un collar (22) adecuado para recibir medios para cerrar del envase. The invention relates to a folded package and a method of making a package preferably for nutritious and non-nutritious products, including foods and beverages or the like. An object of the inventon is to provide a package, where the package may be provided with a print before the package is formed, and where the forming may take place substantially by cold forming so that the print is not affected, and where the package is suitable for receiving a tight-fitting closing means. The novel and characteristic aspect of the method of making a package is that it comprises a sheet comprising at least a layer of plastics to which an amount of inorganic powder material has been added, and that the making of the package comprises at least a combination of punching of the sheet in blanks (10), folding of at least a bottom (4) and at least a side (14), welding and forming of at least a collar (22). Owing to the inorganic powder material and owing to the poor heat effect, minimum shrinkage and very high reproducibility are achieved.
