White PET Leader Tape Width and Perforation Options
For precision-punched white PET leader tape, the relationship between tape width, aperture size, hole pitch and edge distance determines whether the material can work with your existing feeding mechanism. Width alone is not sufficient to confirm equipment compatibility.
| Configuration | Available Specification | Selection Guidance |
|---|---|---|
| 35 mm White PET Leader Tape | 35 mm width; 1.42 mm published aperture | Suitable for equipment requiring a 35 mm leader tape format. Confirm aperture shape, pitch and hole position against the existing tape. |
| 48 mm White PET Leader Tape | 48 mm width; standard or custom perforation | Select according to the equipment's tape path and feeding mechanism. Aperture position and width tolerance should match your drawing. |
| 70 mm White PET Leader Tape | 70 mm width; standard or custom perforation | Confirm the required tape width, hole arrangement, reel dimensions and transport conditions. |
| 35SW / 48SW Configurations | Alternative perforation configurations within the corresponding width families | Provide the exact hole pattern or reference drawing. The SW designation should not be used alone to determine aperture dimensions. |
| Alternative Aperture | 1.98 mm aperture option | Confirm hole shape and dimensions before replacing an existing leader tape. |
| Custom Perforation | Custom hole size, shape, pitch and position | Recommended for proprietary feeding mechanisms or replacement products requiring a specific hole pattern. |
Aperture Definition: A 1.42 mm or 1.98 mm specification does not automatically indicate a circular hole diameter. Square apertures may be specified by their side dimensions. Please confirm the aperture geometry and center-to-center pitch using your existing drawing or sample.
