    摘要： A method for producing a continuous film with a flow film line includes the steps of actively heating an annular nozzle at an outlet via a first tempering component in reference to the inflowing plastic melt such that the exiting plastic melt is heated. While the melt channel system upstream is actively cooled via a second tempering component in referent to the inflowing plastic melt such that the plastic melt flowing along is cooled in the direction towards the annular nozzle. This leads to a stable film because the absolute temperature of the plastic melt is not rising to critical ranges. Simultaneously, melt fractures are avoided when the blow head is heated at its outlet from the annular nozzle.

    摘要： Composite layer having a length and width and comprising a first plurality of repeating, three-dimensional structures having peaks and valleys, comprising a first polymeric material and a second plurality of repeating, three-dimensional structures having peaks and valleys that is adjacent to, and the inverse of, the first plurality of repeating, three-dimensional structures, and comprising a second polymeric material. There is a distance between adjacent peaks comprising the first polymeric material. There is an average of said distances between adjacent peaks comprising the first polymeric material. Any of said distances between adjacent peaks comprising the first polymeric material is within 20 percent of said average distance between adjacent peaks comprising the first polymeric material.
