Abstract:
A method for extrusion coating or extrusion casting, a polymer sheet (4, 5) produced thereby, a roller (2) for use in extrusion coating or extrusion casting, and an apparatus comprising said roller (2), in which micro- and/or nanostructures provided on the surface of the roller (2) are transferred to the polymer sheet (4, 5), and which is applicable to the extrusion coating or extrusion casting of all types of thermoplastic polymer.
Abstract:
The present invention relates to improved laminates whereby a tie layer and a contact layer are coextruded with a base layer, such as a metal foil, as well as uses of the films and laminates to wrap APIs such as nicotine, fentanyl, lidocaine and rivastigmine and in which a specific ratio of tie to contact layer provides good mechanical properties and improved sealing properties.
Abstract:
A method for the manufacture of a packaged dairy product, specifically white cheese, comprises the steps of: introducing a dairy product substance into a container through an opening of the container, subsequently attaching a peripheral portion of a membrane to the container so as to suspend the membrane above the dairy product substance, and dosing a solid substance onto a top surface of the membrane so that the membrane holds the solid substance at a distance from the dairy product substance in the container. A packaged dairy product, specifically packaged white cheese, comprises a container with an opening, a detachable lid covering and sealing the opening, a dairy product packaged inside the container, and a membrane positioned inside the container, a peripheral portion of the membrane being attached to the container so that the membrane is suspended above the dairy product. A method for the manufacture of a weldable membrane and a weldable membrane for use in the method and in the packaged dairy product.
Abstract:
A sheet (2) is made by the method of the invention, in particular for use for the punching of lids for packages, in that a PE layer (5a) and an additional layer PP (5b) are applied to a sheet layer (4) of polyester (PET) by coextrusion to form the finished sheet laminate (2). This ensures that the sheet (2) is transparent throughout, just as it provides the possibility of controlled delamination by separation of the PE layer (5a) from the PP layer (5b), when the sheet (2) is pulled off a package (1).
