Check product flow
Very fine, sticky, oily or hygroscopic powders may behave differently in a filling system.
Choose fill weight with the serving in mind
A 10 g sachet only makes sense if 10 g is an appropriate usage quantity.
Confirm the film
Printed film dimensions, sealing layer, roll direction and machine compatibility need to match the equipment.
Plan a trial run
A small test run can reveal fill consistency, sealing issues or material problems before a larger run.
