Flexible packaging combines product dosing with film or pouch handling and controlled heat, pressure, dwell and cooling.
- Film or pouch dimensions
- Opening and presentation
- Dose timing and product drop
- Seal cleanliness, heat, pressure and dwell
- Pack support through discharge and cooling
Information that makes a recommendation more accurate
- Production film or pouches
- Material and seal-layer data
- Minimum and maximum pack size
- Product sample and target dose
- Seal acceptance test
- Required output and coding
