A clear base film that stays flat on plastic panels
Made for polycarbonate and acrylic, not for ordinary glass.
NorthGuard installs Madico Blister-Free as a clear base layer for polycarbonate and acrylic glazing in Toronto and the GTA. A solar control, decorative or safety film then goes on top, so other films can sit on plastic without blistering.

The specific job Blister-Free 200 is built for
Madico Blister-Free 200 is a special-purpose film for glazing with one specific job to do. Plastic glazing absorbs moisture on humid days and lets it go on dry days. That swing breaks down the adhesive on a standard window film, and the film lifts into blisters. Skylights, sunrooms, shelters and partitions glazed in plastic are where it shows up.
What Blister-Free 200 does, in Madico's figures
Blister-Free 200 is a 0.0025 in clear polyester base film with a silicone pressure-sensitive adhesive that Madico says is unaffected by that moisture movement. A solar control, decorative or safety film then goes on top of it. Madico lists 89% visible light transmitted for the base layer, so it stays close to clear.
Where Blister-Free 200 fits best
NorthGuard suggests Madico Blister-Free 200 for jobs like these.
- Polycarbonate (Lexan) skylights that need solar control film on top
- Acrylic (Plexiglas) sunroom and canopy panels
- Transit shelters and interior partitions glazed in plastic
- School, hospital and treatment facility panels where a safety film goes over the base layer
What Blister-Free 200 will not do
Madico Blister-Free 200 has limits that NorthGuard states before any quote.
- Alone, the film is not a tint, a privacy film or a security film: it is the layer underneath one.
- Blister-Free 200 is made for uncoated polycarbonate and acrylic, and Madico measures its optical numbers on glass, so results on plastic can differ.
- Madico's pages do not name the mounting side, and the top film chosen has to suit the panel.

Blister-Free 200 questions and answers
NorthGuard answers these questions about Madico Blister-Free 200 with Madico's published data.
What is Madico Blister-Free 200?
Madico Blister-Free 200 is a clear 2.5 mil polyester base film for uncoated polycarbonate and acrylic. Its silicone adhesive is designed to ride through moisture changes in the plastic. The visible film goes on over it.
Why do films blister on plastic glazing?
Madico explains that plastic takes in moisture when humidity is high and gives it up when the air is dry. Ordinary film adhesive reacts to that cycle and lifts. Blister-Free's adhesive is not affected by it.
Can other films go over Blister-Free 200?
Madico positions Blister-Free 200 under solar control and decorative films, and under safety film to add fragment retention. Whether a given top film suits a given plastic panel should be confirmed before work.
How does Blister-Free 200 handle cleaners and stains?
Madico's data sheet lists resistance to alcohol, aldehydes, hydrocarbons, chlorinated solvents and diluted acids and alkalines. It also lists stain resistance to most food, chemical and medicinal agents. The materials meet RoHS and REACH.
