Method and data detection device for providing, retrieving and using a data element in a process for producing plastic sheet material

Method for improving a quality of a process, in particular a production process, a logistics process or a management process, within the value creation chain of plastic sheet material, in particular within the value creation chain of a spunbond nonwoven, a meltblown nonwoven, a composite nonwoven, a blown film, a flat film, a plastic plate or a plastic panel, for producing a final product,

• wherein a data element retrieved and used by means of a communication protocol and a data carrier for stage crossing exchange of a variety of different data elements,
• characterized in that
• a quality of the process is described depending on information of the data element, and thus, this quality of the process is described as a function of the data element,
• the data element is used to improve the quality of the process,
• and by improving the quality of the process, the process is changed, so that a desired property, in particular a substance property, a product property, a process property or a market property, is strengthened in its manifestation/dimension and/or an undesirable property, in particular a substance property, a product property, a process property or a market property, is reduced in its manifestation/dimension.
