To avoid electrostatic problems, maintain the relative humidity around machines at a minimum of 50%, and use equipment to remove electrostatic charges. |

YUPO® FGS95 is the most suitable grade for machine
folding. |
| (3) |
Run the final fold parallel with the grain. |
| (4) |
Be aware of the following for folding machines
and calibrations:
- Use the highest precision machines possible.
- Use rubber-steel combination rollers.
- It is critical to use non-abrasive rollers.
- Adjust the roll pressure to the maximum
setting.
- Set the feeder at a precise right angle
to the rolls.

Use equipment for ejecting paper in the delivery
area. Work is difficult with belt systems. |
| (6) |
We recommend 8-page folds. When performing 16-page folds, prior testing is recommended. (YUPO® up to 130 microns is suitable for folding.) |
| (7) |
Airtight pouch-type folds (e.g., 32-page folds)
are difficult using YUPO®. |
| (8) |
After the paper has been discharged at delivery, there will be a tendency for YUPO® products to unfold, but the folds will remain if pressure is applied for several hours using rubber bands, string or applying weight. |

ALPHAYUPO® can splits easily, so do not fold it at right-angles to the grain. Fold after carrying out line stamping by heat in the direction of the grain beforehand. |
