Its design speed is 600 pieces per minute (ppm), and the machine on-site showing speed is 560 ppm maximum. According to the company, the machine efficiency ＞90%; product qualification rate ＞98%; the single piece weight of this product is 18 g; the proportion of SAP in core is 38%; deviation ±5%; and products fully meet design requirements.

The design speed of the NBZ-50 baby diaper packaging machine is 50 bags per minute. Products get into prefabricated bags in single row or double rows. The company claims this machine is the highest speed automatic packaging machine with domestic independent research and development, filling the domestic void of packaging machines in this field.

The company has also launched its WBZ-70 sanitary napkin automatic packaging machine. The stable working speed of this machine is 70 bags per minute; 8 to 20 pieces per bag.
