Quel est le Rendement Maximum qu’un VFFS Peut Atteindre?

Attention ! Le contenu de cette page est disponible en anglais.

On vertical packaging machines the final output is significantly affected by the number of lanes on the machine. There are of course other relevant factors affecting the productivity like the machine model, but still the number of lanes is key.

In fact despite the RPM value has a fundamental role in determining the production rate, the final output always equals to RPM multiplied by the number of lanes. This is a considerable advantage of VFFS, as there is no need to excessively stress mechanically the machine to achieve a greater output when you can work with more lanes.
The achievable RPM depends on many factors like the dosing system, bag type, bag size, type of product, type of laminating film, type of sealing and so on.

Let’s now assume the following rough estimation of working time: an 8-hour shift per day, 21 days per month, 260 days a year.

RPM	Number of lanes	Bags per minute	Bags per hour	Bags per shift	Bags per month	Bags per year
60	2	120	7,200	57,600	1,209,600	14,976,000
60	4	240	14,400	115,200	2,419,200	29,952,000
60	8	480	28,800	230,400	4,838,400	59,904,000
60	16	960	57,600	460,800	9,676,800	119,808,000
120	2	240	14,400	115,200	2,419,200	29,952,000
120	4	480	28,800	230,400	4,838,400	59,904,000
120	8	960	57,600	460,800	9,676,800	119,808,000
120	16	1,920	115,200	921,600	19,353,600	239,616,000

Universal Pack machines are designed and built to work 24/7, with downtime only for maintenance and cleaning operations. Just assume that having two 8-hour shifts per day would double the output in the table.
