Abstract (en)

[origin: EP1416087A1] Production of a coated substrate involves contacting a multilayer free flowing curtain with a continuous web substrate. Production of a coated substrate involves contacting a multilayer free flowing curtain with a continuous web substrate. The multilayer free flowing curtain comprises at least two layers imparting at least two different barrier functionalities selected from oil and/or grease barrier, water vapor barrier, water resistance or oxygen barrier functionality. The coated substrate has a kit value of at least 5 (preferably at least 8, especially at least 11) in the flat-test when an oil and/or grease barrier layer is present; has a water vapor transmission rate of less than 50 (preferably less than 40, especially less than 30) g/(m 2>/day) (50% relative humidity, 23[deg]C) when a water vapor barrier layer is present; has a 10 minute Cobb value of less than 20 (preferably less than 12, especially 1.5) g/m 2> when water resistance layer is present; and has an oxygen transmission rate of less than 200 (preferably less than 150, especially less than 100) cm 2>/(m 2>/24 hour/bar) (1 atm, 23[deg]C, 90% relative humidity) when an oxygen barrier layer is present.
