Flexible packaging can be produced in many variations and most of the time the finished package is what will be presented in the shops. But food and cosmetic companies also demands other types of delivery. This because these companies use many automated systems to fill the packages with their content.

For this many food and cosmetic packaging companies use the packaging on rolls. These rolls are implemented in their workflows so the machines can automatically fill the packages. To produce these packages the printing companies specialized in food packaging are investing a lot in new machines to produce those packages on the roll as effective as possible.

Especially because many of those packages must have an output of a tube with a glued part on the back. The process is a followed. First the printing machine is printing the design on the plastic. This can be one sided but also two sided. This printing process is done on root machines. It means the machine is not printing sheets but a complete roll. Just the same concept as newspapers are printed. The second step is to add this roll to a special folding and gluing machine. In fact this machine makes a very long tube from this printed roll and delivers it also on a roll. During this folding the backside will be heated and glued so the tube is complete.

The finished rolls simply are fitted in a machine at the food and cosmetic companies, the bottom side will be cut and glued, the content is added and the top can be closed. All done automatically by machines. More information can be read here.
