Drytac coated a low-tack, water-based acrylic removable adhesive on a white BOPP film and supplied the material in self-wound format by adding a thin PET release on the face of the BOPP.
The Challenge
Drytac, the leading international manufacturer of self-adhesive materials for the large-format print and signage markets, recently worked with one of its converter partners on a project to create a complex, multi-step medical device die cut.
The customer had been seeking a sturdy film coated with low-tack adhesive to support the transport of a die cut product through several stages of converting in their own facility.
The primary challenge for Drytac on this project was to ensure the adhesive was strong enough to hold the die cut through the converting process, while also having an easy release when removed from the assembly aid without leaving any residue on the surface.
The Solution
In response, Drytac coated one of its low-tack, water-based acrylic removable adhesives on a white biaxially oriented polypropylene (BOPP) film and supplied the material in self-wound format by adding a thin PET release on the face of the BOPP.
To support the customer with this process, Drytac also provided a number of sample sheets for the initial evaluation stage, allowing them to identify the correct coat weight to achieve the right balance of adhesion and release from the part.
In addition, the flexible coating weights of the solution ensured any other medical products that they engineer with different substrates will be able to use the same face materials and adhesive, but custom coated for each specific part.
