The Process of Making Paper Sticky
Sticky notes are like Roman gladiators. Gusts of wind, big movements, and greasy fingers aren't powerful enough to make them fall. They stick around through thick and thin, making them a must-have everywhere from home to the office.
The real question is: why are they so sticky? It all comes down to the fascinating way they're made!
How Is a Sticky Note Made?
First things first, it's important to understand that sticky note and Post-it® are not synonymous. Sticky notes could be considered off-brand versions of Post-its®, and each manufacturer has their own process for creating them.
Generally speaking, the process for making sticky notes includes:
Step One: The manufacturer's specific formula for the adhesive is mixed together.
This isn't done in the way you'd mix together flour, eggs, and chocolate chips to make cookies. Rather, most companies have machines that automate the process so it's done quickly and efficiently.
Step Two: Paper is fitted with the adhesive on the top as it passes through rollers.
During this step, the paper is also cut into larger sizes as the sticky glue is added to the top of each individual piece.
Step Three: The paper goes through a giant oven to ensure the adhesive is dry.
This isn't an oven like the one in your kitchen, but is instead specially designed to dry the adhesive on sticky notes while at the same time keeping it nice and sticky.
Step Four: Another device stacks the sheets of paper on top of each other to form large pads.
Once the glue is dry, the larger pieces of paper are all stacked on top of each other. The number of sheets is determined by the number of sticky notes that are in the set.
Step Five: The stack of paper is pressed down by a machine to create a firm grip.
At this stage, the paper is placed between giant presses that squeeze it all together. This helps ensure the sticky note is super strong.
Step Six: The paper is cut into the intended shape for the sticky notes, which is usually 3 X 3 squares.
A machine automatically cuts the sticky notes into their desired size and shape, which is typically 3 x 3 squares. Die cuts can be used at this point as well if the sticky notes are in a shape other than squares like hearts, stars, or awareness ribbons.
Step Seven: Each sticky note sheet is screen printed or digitally printed with some kind of design.
Some sticky notes are blank, but others are branded with a company logo. A screen or digital printer will add this design to each individual sheet.
Step Eight: The sticky note pads are packaged and shipped to stores or online wholesalers.
The glue and ink are dry and the sticky notes are ready to go! They're individually packaged, shipped in bulk to retailers or online stores, and bought by consumers like you.
