paper microperforating unit / for plastic films
paper, for plastic films
Materials like film, foils, foams, paper and laminates are often used for packaging material where ventilation holes are necessary. Microperforation is applied with needle- and micro-perforating cylinders, hot or cold, depending on the material. A perforating density of 100 holes/cm2 can be achieved. In addition to the packaging industry needle units can be used for applications in the hygiene and filter industry as well as for synthetic leather in the automotive and furniture industry.
