There are several specifications to consider when it comes to choosing the right packaging equipment for food, dairy and home & personal care (HPC) processors. In alignment with Hema
, Synerlink’s product offerings and the technical capabilities have grown in these markets. Today’s portfolio includes a variety of sequential linear and continuous rotary machines.
Which technology should you choose?
It all depends on your needs. Before making any decisions, you should consult with a trusted packaging solution provider. To give you an overview of the main differences between sequential linear and continuous rotary machines in Synerlink’s
portfolio, we’ve summarized the most important points below.
Both the sequential linear machines and the continuous rotary machines in Synerlink portfolio have been thought for different types of packaging styles. There are linear and rotary machines that deal with bottles, single cups, cans, and jars. Although
there are styles of packaging, like multi-cups, twin cups, mini-cups and trays that are more indicated for sequential linear machines. In the same way, mini-jars are more indicated for continuous rotary machines.
Besides filling pre-formed packaging, whether it is sequential linear machines or continuous rotary machines, the Synerlink portfolio also offer the possibility to add a bottle blowing module to produce your bottle packaging on site. In order to produce
your cup packaging on site from reel of plastic, our sequential linear machines also offer the possibility to thermoform packaging.
While sequential linear machines tend to develop in length, continuous rotary machines tend to be more compact at higher speeds for bottle, can and jar packaging. Although, both linear and rotary machines increase in size under certain circumstances.
For example, linear machines increase in width when speed increases or as ergonomics increase. While rotary machines increase in size with the increase in speed, packaging size or for specific filling needs.
On one linear machine, it is possible to have several dosing modules, placed one next to the other to satisfy specific filling needs of the products. On the same way, it is possible to place multiple dosing modules on rotary machines provided that
there is a turret for each.
Sequential linear machines are especially indicated for products that go from liquid to non-viscous. The products can either be pre-mixed or mixed directly at the filling stage of the packaging process on linear machines and they are also indicated
for multilayer products, for example with fruits or Chantilly cream on the bottom or at the top. On the contrary, continuous rotary machines are especially indicated for products that go from liquid to viscous products that are pre-mixed. Continuous
rotary machines are also indicated for products that contain pieces. Moreover, product filling from 5 to 90 degrees is also possible on rotary machines.
For both sequential linear and continuous rotary machines, the closure module(s) depend on the type and material of the packaging. There are several possibilities allowed, whether it is flat lid sealing, capping, lid placement or seaming. For both
sequential linear machines and continuous rotary machines screw capping technology is a possibility, where this technology is helped in rotary by the inertia of the motion of the machine.
Both sequential linear and continuous rotary machines are indicated for single portions. Moreover, sequential linear machines are also indicated for multipacks and multiflavour multipacks. On linear machines, when it is conceived, you can change the
format of your packaging without needing to change the slats. On continuous rotary machines, the change of format is also possible when compatible.
The sustainability benefits are the most interesting for bottle blowing machines, whether they are sequential linear or continuous rotary and for thermoforming, filling and sealing linear machines.
