Film Tubes


For business machines such as printers that offer ever higher speed, ever smaller dimensions, and ever higher image quality based on pico-liter ink control, Junkosha's advanced polymer molding technologies provide tube products with controlled thicknesses on the order of several tens of microns.
The products offer hydrophilic properties through sodium etching, plasma, and corona discharge treatments for processing adhesion.


  • The product line consists of thin-wall tubes and heat-shrinkable tubes with thicknesses of several tens of micrometers and inner diameters ranging from several millimeters to 100 millimeters.
  • Products with added functions available for specific applications, including heat-shrinkable tubes with controllable shrinkage direction, tubes with inner adhesion, tubes with controlled conductivity, and ultrathin tubes
