摘要： A coated paper-based substrate for manufacturing a container and a method for preparing the same. The coated paper-based substrate comprises a cellulosic fiber-based substrate coated on a first surface with a coating A and coated on a second surface with a coating B. The coating A comprises at least one layer of an extruded or laminated polymeric film or of a laminated foil. The coating B comprises at least one layer obtained by applying an aqueous dispersion of at least one polymer or copolymer capable of providing a water and/or moisture barrier to the second surface of the paper-based substrate once coated. The extruded or laminated polymeric film and the polymer or copolymer of the aqueous dispersion are different. The coating A and the coating B are heat sealable to each other.

摘要： A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 2 m N/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 m N/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.

摘要： A foldable paper-based substrate coated with primer coat and top coat. Primer coat includes a wax-free aqueous dispersion wherein a dry film thereof has a flexibility of at least 1100% for a film thickness from about 1.0 to about 2.5 mm. Top coat is blocking resistant and includes an aqueous dispersion of a polymer providing water resistance, grease or oil resistance, heat resistance, odor barrier, moisture barrier and/or heat sealability to the paper-based product. The top coat aqueous dispersion is characterized in that a dry film thereof has a flexibility of at least 570% for a film thickness from about 1.5 to about 2.5 mm. A process for preparing the coated foldable paper-based substrate includes applying the primer coat to the surface of the paper-based substrate, applying the top coat and drying the coats. The primer coat may be dried before application of the top coat.

The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 25 mN/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 mN/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described.
