Film moves through a vacuum metallizer at high speed, and every meter of that travel generates static charge. In roll-to-roll processing, plastic webs build thousands of volts of static as they unwind, pass over rollers, and rewind. Most of the time this charge causes no visible problem — until it…

Adhesion failure ranks among the top reasons converters reject metallized film. The metal layer looks perfect on the rewind roll, yet printing smears, lamination bubbles, or heat sealing peels the coating right off. Each rejected roll costs material, downtime, and customer trust. Metallized film adhesion testing catches these problems before they…

Walk into any party store, and metallic balloons dominate the display: silver stars, gold hearts, rainbow numbers. These shiny foil balloons do not get their luster from paint or ink. They start as plain, transparent polymer film and pass through a vacuum metallizer, where an ultra-thin aluminum layer transforms them…
