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 pe- ripheral portion of a membrane to the container so as to suspend the mem- brane above the dairy product substance, and dosing a solid substance onto a top surface of the membrane so that the membrane holds the solid sub- stance 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 mem- brane for use in the method and in the packaged dairy product.
Abstract:
A method for producing a high aspect ratio micro- or nanostructured thermoplastic polymer foil, or a nanostructured thermoplastic polymer coating on a carrier foil, comprising at least one high aspect ratio nanostructured surface area, is disclosed. The method comprises applying a high aspect ratio nanostructured surface on an extrusion coating roller and maintaining the temperature of the roller below the solidification temperature of the thermoplastic material. A thermoplastic foil and a thermoplastic coating made by the method is also disclosed.
Abstract:
A laminate for use in packages comprising a base layer (3), a welding layer (1), and an adhesive layer (2) sandwiched there between. The adhesive layer (2) is a hot melt or a pressure sensitive adhesive (PSA) having a shear rate of 10-150 minutes at 40 °C using a load of 1000 g at 40 °C in a test area of 12.5 mm x 25 mm. The welding layer (1) comprises a layer of a polyethylene (PE) copolymer, and optionally an additional layer of PET, PE, such as low density polyethylene (LDPE) and/or PP. By the method of making a laminate, it is possible to apply to a base layer (3), an adhesive layer (2) of hot melt/PSA and subsequently a welding layer (1) in one and the same working process in order to form a reclosable laminate (9). This laminate (9) may serve as a reclosable lid on e.g. a package tray (4, 5). The laminate exhibits a reduced risk of formation of cracks or so-called piping in the laminate. Use of the laminate is also disclosed.
Abstract:
A packaging sheet comprising: a paper base sheet having a first surface and a second surface, the second surface being positioned oppositely to the first surface; a first coating on the first surface of the paper base sheet; and a second coating on the second surface of the paper base sheet; wherein the first and second coatings can be selected from a range of options.
Abstract:
A packaging sheet for packaging of butterable products, such as butter, the packaging sheet comprising: an inner surface and an outer surface, the inner surface being configured for facing the butterable product, a paper base sheet with a first surface and a second surface, the paper base sheet comprising a paper layer and a light barrier layer or light barrier coating on the paper layer, the barrier layer or barrier coating forming the first or the second surface of the paper base sheet and forming a barrier against light for light protection of the butterable products, an inner polymer contact layer comprising a polyolefin and/or a polyester, a surface of the contact layer establishing said inner surface of the packaging sheet, and one or more polymer tie layers positioned between the paper base sheet and the contact layer, a first surface of the one or more tie layers facing the paper base sheet, a second surface of the one or more tie layers facing the contact layer, wherein the one or more tie layers and the contact layer are co-extrusion coated on the second surface of the paper base sheet, and wherein the paper base sheet has a grammage of above 50 g/m2, the one or more tie layers have a total grammage of 1 to 10 g/m2, and a total grammage of the coextrusion coated one or more tie layers and contact layer is 5-20 g/m2.
Abstract:
A sheet laminate for being used as a puncturable top web for a blister package, comprising: an aluminium base sheet layer;at least one tie layer being of, comprising, essentially consisting of or based on polyolefin; a welding layer being of, comprising, essentially consisting of or based on polyester or polypropylene; wherein the welding layer and the tie layer are coextrusion coated on the base sheet layer so that the at least one tie layer is disposed between the base sheet layer and the welding layer, whereby the welding layer is attached to the base sheet layer by means of the at least one tie layer. A blister package, wherein the sheet laminate is attached to a bottom web with product cavities. A method of manufacture of the sheet laminate and of the blister package, wherein the coextrusion coating step of the manufacture of the blister package is carried out simulataneously with extrusion lamination of a paper layer.
Abstract:
An applicator tool (10) for attaching a membrane (5) to an inner surface of a side wall (51) of a container (52) for a packaged dairy product, comprises a bottom part (1) with a bottom surface (11) for abutment against the membrane (5), said bottom surface (11) defining a bottom level, the bottom part (1) having a circumferential surface (13) adjacent to the bottom surface (11), the bottom surface (11) and the circumferential surface (13) together defining a convex surface (12a) circumscribed about the bottom surface (11) and the circumfer- ential surface (13); and a plurality of activating protrusions (34) respectively movable relative to the bottom part (1) between an active position in which the activating protru- sions (34) protrude relative to the convex surface (12a) and an inactive position in which the activating protrusions (34) are retracted from their active positions.
Abstract:
A method for manufacture of a foil for enclosing or wrapping a product to be heated in an oven, comprising the steps of: providing an aluminium layer comprising aluminium, applying a first ink material at a surface of the aluminium layer to form a first ink layer, and applying a second ink material at a surface of the first ink layer to form a second ink layer, the first ink layer thereby being positioned between the aluminium layer and the second ink layer, the first ink layer being adapted for absorbing radiant energy, the second ink layer being adapted for allowing radiant energy to pass through it so as to reach the first ink layer, wherein a binder system of the first and/or second ink material is based on PVB (polyvinyl butyral).
