The Leybold Optics PAK series roll-to-roll metalizing system provides high-quality aluminum or transparent aluminum oxide coatings for packaging materials. Use for cost-effective optical, protective and barrier properties on polymer and paper substrates.
Our powerful plasma pre-treatment can be combined with our AdhesionPlus gas-injection module. This brings you cleaning, ablation, cross-linking and surface modifications, optimizing the process conditions to improve layer adhesion and reduce permeability.
Thanks to the powerful plasma-activated deposition of transparent aluminum oxide layers, innovative high-rate evaporator, wire feeding technology, gas distribution and fully automatic layer cross control, high product quality in terms of uniformity, transparency, barrier performance and long-term stability can be achieved. An additional plasma treatment allows in-situ aging of the layer.
The special surface of the roll guarantees an excellent grip without foil slippage even when using a small wrapping angle. Beside the outstanding winding performance, the thin layer of the surface refinement still provides efficient cooling performance. Even temperature-sensitive materials can be processed with no limitations in speed.
Leybold Optics PAK
Bühler’s Leybold Optics PAK system offers versatile performance for a wide range of aluminum or copper coatings in 1300 mm to 2500 mm coating width options. These include: very thin coatings, such as those used for interlayers between architectural glass panels; medium thicknesses, as used in food packaging; thick coatings, typically used in the packaging of highly photosensitive electronics.
Leybold Optics PAK+
The Leybold Optics PAK+ is specifically designed for margin-sensitive high-volume packaging applications, giving you up to 40% faster processing speeds than conventional systems, whilst maintaining a high product quality. The Leybold Optics PAK+ is available in 2500 mm to 3700 mm coating width options for aluminum or copper coatings.
Leybold Optics PAK T+
Employing plasma-reactive deposition, our Leybold Optics PAK T+ is designed to apply transparent aluminum oxide layers onto flexible plastic substrates such as PET and (B)OPP, enhancing barrier performance and long-term stability with striking visible results. The Leybold Optics PAK T+ is available in 2500 mm to 3700 mm coating width options for aluminum oxide, pure aluminum or copper coatings.
