What is Reseal Technology?
Many products require functional resealable openings that can open and close numerous to keep the product fresher for longer.
In spring 2026, Multi-Color Corporation introduced ReseaLabel™ technology to its rapid prototyping center (RPC).
I was given the opportunity to create processes and templates from scratch for MCC’s prototyping.
Resealable packaging is defined by three major pieces during the creation process:
The heat sealed edges
The clear “resealable” adhesive film
The cut in the material that will open to reveal the product.
Cutting the materials by hand leaves room for mistakes and inconsistencies, so creating a machine oriented process is a must.
Template
lastly, the edges were seamed and trimmed.
The process began with creating an easy and precise way to add cut and registration marks without damaging the preprinted film material.
This was achieved by creating an overlay and matching cut file in Adobe Illustrator.
and created a cut file for the opening.
As the overlay printed onto the clear material, I cut the preprinted film with extra space for seam allowance, then placed onto a cutting mat.
Once opening was cut, the overlay was removed from the preprinted material. The film was not removed.
The sticky mat held everything flat and in place, making the application of the seal easier.
A pressure sensitive label was applied to the pre-printed film.
The size is fully customizable, with multiple adhesive and
tamper-evident options, and can be printed in up to 8 colors.
I took the official art and separated out the key elements, then printed these elements onto clear material using a Mimki UJF-6C42 MkII printer,
Once the overlay finished printing, the middle, where the opening will be die-cut, was cut out and removed.
After sticking the fully lined up overlay to the mat, all three items were placed in a Mimaki cutting plotter.
FineCut read the overlays’ registration and cut marks, then used the matching cut file to cut the opening into the film.
Lining up the key elements with the art ensures the registration marks and cut is in the exact same position every time.
Heat Seal
To finalize the packaging, the back and edges were heat sealed.
First, the back edge was seamed,
then, the plastic cookie tray was entered,
