Definitions

  • the present invention relates to a tubular film Plastic, especially for the production of packaging bags.
  • WO 97/03899 proposes not to use standardized garbage bags, but rather the waste in portions in foil containers to pack, each in the desired Size can be made from a tubular film.
  • Such Tubular films are usually used in a gathered form Provided and can by means of film bubble extrusion or be produced in the slot silo process. Decide in the process the film thickness and the base material essentially about the film properties accordingly essentially only by changing these two parameters can be changed.
  • the object of the invention is therefore a tubular film of the type mentioned at the beginning, which makes it possible the properties such as the static load capacity to be more flexible.
  • Double-walled tubular film with two film tubes in Hose in hose arrangement is made.
  • the two Foil tubes can be made of different Consist of materials and have different wall thicknesses, so that the properties of the tubular film through Changing these parameters optimally to the existing ones Needs can be adjusted.
  • it is possible to have a high static load capacity Tubular films while maintaining relatively small wall thicknesses ensure where in usual use of a conventional film tube requires large wall thicknesses that would be the manageability of the tubular film would affect.
  • the two film tubes can connect with each other locally.
  • the film tubes on at least one to connect the axial end region to one another, in particular to make a bag this way. They can also Foil tubes over their length in several places in particular be connected to one another at certain points.
  • FIG. 1 shows an embodiment of a tubular film according to the present invention.
  • This Tubular film is double-walled and exists of an inner film tube 1 and an outer film tube 2, in hose in hose arrangement are provided, the outer film tube 2 a slightly larger diameter than the inner film tube 1 owns.
  • the two film tubes 1, 2 consist of different plastic materials, in particular biodegradable plastics are used, and have different wall thicknesses. Like in the Drawing is clearly visible, the film tubes 1, 2 connected to one another at several points 3.
  • tubular film offers the advantage that by selecting appropriate Wall thicknesses and materials properties, in particular the static load capacity of the tubular film, optimal be adapted to the existing needs can.
  • the tubular film can be conventional Made by extrusion or in the slot silver his.
