A child-resistant package, such as a blister pack or a strip pack, comprising a number of packaged products, a top web sealed to a bottom web, two weakened tear lines dividing the package into four sections, the two tear lines intersecting each other in a peel area, so that tearing along the two tear lines allows access to a peel tab positioned in a corner of at least one of the sections, pockets being provided in sections, wherein at least one of the tear lines, where it is closest to a peripheral circumferential rim of the package, is provided at a distance from the circumferential rim of at least 2 mm, and/or the or each tear line extends less than 99 % of the associated distance between said two points.
Abstract:
A heat-sealable packaging sheet comprising a base sheet of paper, a heat- sealable ethylene layer, a polyamide layer, and a polymer coextrusion coating tie layer, wherein the tie layer, the polyamide layer, and the ethylene layer have been co-extrusion coated together on a second surface of the base sheet, wherein the base sheet constitutes at least 73 wt% of a total grammage of the packaging sheet, and the coextrusion coating constitutes no more than 27 wt% of a total grammage of the packaging sheet, wherein the base sheet has a grammage of 60 to 150 g/m2, and the coextrusion coating has a grammage of 5 to 32 g/m2, wherein the tie layer has a grammage of 1 to 30 g/m2, wherein the polyamide layer has a grammage of 1 to 30 g/m2, wherein the ethylene layer has a grammage of 1 to 30 g/m2, and wherein the ethylene layer essentially consists of a coextrusion coatable copolymer of ethylene and at least one acid comonomer, wherein the at least one comonomer constitutes 5 to 20 wt% of the ethylene layer.
Abstract:
A heat-sealable packaging film, comprising a base film mainly comprising polyethylene terephthalate, the base film forming a layer of the packaging film; and a heat seal layer mainly comprising an IPA-modified copolyester; wherein the heat seal layer has been extrusion coated on the base film so that the heat seal layer material forms an exterior, amorphous, and heat- sealable heat seal layer.
Abstract:
Aspects of the disclosure relate to methods for making large areas of high aspect ratio micro or nanostructured foil using existing extrusion coating equipment. A method is disclosed 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. 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:
The present present disclosure relates to a laminate film including a water resistant or oxygen resistant base layer, and co-extrusion layer. The coextrusion layer may include a tie layer and a contact layer, and the contact layer may include a polymer such as cyclic olefin copolymer, a polyamide, or an ethylene vinyl alcohol. A total loading of the tie layer may be in the range of 3-9 g/m2 and wherein a loading of the contact layer is: loadingcontact=x*loadingtie, wherein loadingcontact is the loading of the contact layer, loadingtie is the total loading of the tie layer, and x is in the range of 0.8 to 3.
Abstract:
The present invention relates to a blister package (1) consisting of a lower web in which a row of cavities (3) is provided, and an upper web (12) which is welded to the provided lower web, and wherein perforation lines (7) are provided between adjoining cavities, and wherein there is an area (6) in connection with each cavity where the upper web is not welded to the lower web, such that a snip is created, said upper web being welded to the lower web by a first inner weld (4) which surrounds the cavity completely, as well as a second outer weld (5) which surrounds the cavity around the first weld and adjoins the area where the upper web is not welded to the lower web. The invention also relates to a method of making the blister package.

Abstract:
A solid nano- or micro-structured thermoplastic foil including a nano- or micro-structured surface area is produced by providing an extrusion casting roller for an industrial polymer extrusion casting process using a thermoplastic material, applying a nano- or micro-structured surface on the extrusion casting roller, maintaining a temperature of the casting roller below a solidification temperature of the thermoplastic material while the casting roller and the counter roller are rotating, and continuously applying a melt of the thermoplastic material between a counter roller and the casting roller while the casting roller and the counter roller are rotating. A rotational velocity of the casting roller may be 10 meters/minute. The melt of the thermoplastic material is moved between the casting roller and the counter roller while the rollers are rolling, and the melt of the thermoplastic material is solidified upon contact with the casting roller to form the thermoplastic foil.
