The making of the Pritt Glue Stick
Did you know that Henkel invented the very first Glue Stick in 1969? The funny thing is, the idea came by studying a tube of lipstick!
This type of applicator has proven to be an easy and convenient way to glue. This is the best gluing solution for children: Easy, clean and safe.
You see ... good ideas can come from anywhere!
Today, Henkel has lots of scientists…
... who think of new products and test their ideas in laboratories like this one.
Have you ever made a cake or cookies? We use the same idea for making glue sticks. A scientist created a glue "recipe" that we apply to produce the Pritt Stick.
The Pritt Stick "kitchen"
This is where production begins - the Henkel Pritt Stick "kitchen". The large tank in the background is where all the glue ingredients are mixed together and cooked following our special "glue recipe".
After the glue is mixed, it is pumped down to the floor below to the filling line.
Thirty years ago, …
... computers were not used to produce glue sticks. Today, our factory runs more efficiently and the entire process can be monitored closely by computer.
Still some steps have to be supervised by our scientists. Here you can see a Henkel technician ensuring that the temperature for heating and cooling water is correct.
Now we're down on the factory floor
The filling process begins as empty glue stick tubes are transported from a large holding bin up a moving ramp and onto the filling line conveyor.
Henkel produces three sizes of glue sticks: 11, 22 & 43 g. Although we have different filling lines for each size, they all run basically the same way in our factories all over the world.
The automatic machinery…
... helps the empty glue stick tubes line up neatly - and upright. They travel along the conveyor line on their way to their first stop, the filling station.
Here, our 11g glue stick tubes enter the filling station. Our lines are able to fill more than 200.000 sticks per day. At this stage, the glue must be in liquid form in order to fill the tubes, therefore it is very hot.
The tubes of hot, liquid glue must move to the cooling station before they can be capped and handled further.
The cooled tubes are ready to be capped
The automatic machine "hand" can cap much faster than human beings! After the glue sticks are capped, they are placed onto packing trays - automatically of course - and put through a second cooler to make sure that the warm glue turns into a stick ready for you to use!
The glue sticks are shipped to stores and are ready to help you with all your "sticky" projects at home, school or office - clean, quick and accurate.
