Dry Lam 27"x500' 2.25" Core School-Lam Laminating Film

Not All School Grade Laminating Films Are Created Equal.In the early days of making laminating film, gauge (or thickness) was the way laminating film was measured. A simple micrometer would tell you the thickness of the product. School grade films measured 1.5 mils in thickness (mils is a measurement in thousands of an inch, so 15/1000 of an inch).School grade laminating films are a petroleum-based product. There is a base film made of Polyester and a thermally activated adhesive made of Low Density Polyethylene (LDPE). The combination of the two materials creates the total thickness of the film. As petroleum-based materials have become more expensive, manufacturers have come up with ways to reduce the cost of making these school grade laminating films.
