A method of preparing a multi-layer assembly, or of protecting a surface of a multi-layer substrate from damage and/or contamination and/or debris, said method comprising the steps of: (i) providing a composite film comprising a polymeric base layer having a first and second surface and disposed on the first surface thereof a polymeric protective layer having a first surface and a second surface such that the first surface of the said base layer is in contact with the first surface of the polymeric protective layer, wherein said polymeric protective layer comprises an ethylene-based copolymer, and preferably wherein the polymeric base layer comprises a polyester derived from one or more diol(s) and one or more dicarboxylic acid(s); (ii) removing said polymeric protective layer from the first surface of said base layer; (iii) disposing on the exposed first surface of said base layer one or more functional layers to provide a multi-layer substrate, wherein the, or at least the uppermost, functional layer comprises zinc and/or tin in an amount of from about 5 to about 80 wt % of said functional layer; and (iv) disposing a polymeric protective layer comprising an ethylene-based copolymer onto the exposed surface of the, or at least the uppermost, functional layer comprising zinc and/or tin to provide a multi-layer assembly.

Multi-layer functional film and production method thereof

Methods and apparatuses for coating a flexible substrate are provided. The flexible substrate is guided over a process roller. The flexible substrate has a first protective film, which is removed from the flexible substrate before the flexible substrate reaches a coating zone of a coating device located opposite the process roller. The first protective film is removed from the flexible substrate after the flexible substrate has formed a mechanical contact with the surface of the process roller. A second protective film is applied to the coated side of the flexible substrate after the flexible substrate has left the coating zone of the coating device and before the mechanical contact between the process roller and the flexible substrate is ended.

Method for coating a flexible substrate provided with a protective film

A plastic substrate having a porous layer is disclosed. In an embodiment, the porous layer is formed at least partially from a material of the plastic substrate and has pores. The proportion by volume of pores is greater in a first region of the porous layer than in a second region of the porous layer. The second region follows the first region, as seen proceeding from the plastic substrate. The porous layer can be produced by a plasma process that simultaneously effects structuring of the plastic substrate by ion bombardment and coating of the plastic substrate.

Methods are provided for modifying a transparent and electrically conductive metal-oxide coating deposited on a plastic substrate. At least one surface region of the metal oxide coating is impinged by a pulse-driven electron beam. The impingement of the surface region of the metal oxide coating by the pulse-driven electron beam occurs inside a vacuum chamber into which hydrogen, argon, nitrogen, or oxygen, or a gas mixture of at least two of the above-mentioned gasses has been introduced.

A plastic substrate has a porous layer on a surface. The porous layer is formed at least partially from a material of the plastic substrate and has pores. The proportion by volume of pores is greater in a first region of the porous layer than in a second region of the porous layer. The second region follows the first region, as seen proceeding from the plastic substrate. The porous layer can be produced by a plasma process that simultaneously effects structuring of the plastic substrate by ion bombardment and coating of the plastic substrate.

The invention relates to a method for vapor-depositing strip-shaped substrates with a transparent barrier layer made of aluminum oxide by reactively vaporizing aluminum and admitting reactive gas in a strip vapor-deposition installation. The invention provides that, before coating with aluminum oxide, a partially enclosed layer made of a metal or of a metal oxide is applied to the substrate by magnetron sputtering.

Process for monitoring an alternating-voltage discharge between the electrodes of a double electrode and an apparatus. The process includes measuring values of at least one of a discharge current and a discharge voltage for each half-wave within an alternating-voltage discharge period, determining a difference between the measured values of a second half-wave and the measured values of the first half-wave, and comparing the determined differences to specific tolerance values. When the specific tolerance values are exceeded by the determined differences, a power supply is reduced, whereby the discharge is at least briefly suppressed. The apparatus includes a double magnetron including first and second targets arranged to form a double electrode, and a power supply coupled to supply power to the first and second targets. The power supply includes a measurement unit for measuring values of at least one of discharge current and discharge voltage, such that at least one of a discharge current and a discharge voltage for each half-wave within an alternating-voltage discharge period is measured. A device for determining a difference between the measured values of a second half-wave and the measured values of the first half-wave is provided, as well as a device for comparing the determined differences to specific tolerance values, and a device for at least briefly suppressing the discharge when the specific tolerance values are exceeded by the determined differences.
