Polyethylene runs on the same metallizers as PET and BOPP, and yet it exposes three limits at once. LDPE melts between 105 °C and 115 °C, its untreated surface energy sits near 31 dyn/cm, and a thin, low-modulus web folds under tension that other films simply ignore. Handle those three limits, and…

At 121 °C, a metallized CPP lidding structure leaves the comfortable world of ambient laminates. Four things change: the seal layer resin, the lamination adhesive system, the barrier number you can promise, and the migration test you must pass. A structure that seals flawlessly at room temperature will creep, delaminate or lose…

You can run polyester film on the same metallizer you use for BOPP — but you cannot run it on the same recipe. Metallizing PET film demands four changes: a moisture plan, a lower tension setpoint, a re-checked dyne level, and a grade-specific drum temperature. Skip those changes, and you get pinholes,…
