Abstract: A method of constructing a package having printed indicia of acceptable quality includes providing at least one layer of foamed thin film wherein the layer of foamed thin film has a caliper of between 10 and 250 microns and comprises between 5% to 50% density reduction as compared to a non-foamed thin film of substantially the same caliper and composition. A first surface of the at least one layer of foamed thin film is the printed surface of the package. The indicia is printed on the printed surface by applying ink to a printer surface and contacting the printed surface with the inked printer surface to coat the printed surface with ink. The printer surface includes a plurality of dots configured to contact the printed surface to imprint the indicia on the printed surface. The surfaces of the dots have a dot percentage of no more than about 70%.

Abstract: Bag comprising a material having a 2% secant tensile modulus of at least 100 MPa as measured according to ASTM D882 and a thickness of at least 30 microns and containing a composition comprising: thin, shaped particles having a main length, a, of at least 1.5 mm, base granules having an average geometric mean particle diameter, of at most 0.8*a mm, or even at most 0.6*a mm, or even 0.4*a mm.

Abstract: The present invention relates to a process for making a laminate comprising paperboard and plastic film, and a non-aqueous adhesive layer between the paperboard and the plastic film, the process comprising the steps of: (a) surface oxidation treatment of at least one side of the plastic film; and (b) extrusion laminating the plastic film to the paperboard; wherein the non-aqueous adhesive layer is applied by extrusion between the plastic film and the paperboard to form the laminate, and wherein the process further comprises the step of printing inks onto the surface oxidation treated surface of the plastic film either before or after the extrusion lamination step; and to a process for making a carton, whereby the carton is erected from a blank which is formed from the laminate.

Abstract: The invention relates to bag (10) comprising a line of weakness (28) for ease of opening, and a reclosing means (32), wherein the bag (10) comprises a front panel (12), back panel (14) and opposing side panels (16, 18), the panels being sealed together to provide a top section (24) and a bottom section (26), and wherein the line of weakness (28) extends around all of the front (12), back (14) and side (16, 18) panels so that the top section (24) is completely removable from the rest of the bag, and wherein the reclosing means (32) is attached to the front (12), back (14) and side (16, 18) panels adjacent to the line of weakness (28).

Abstract: A process of applying a polymeric film sleeve to a product by a stretch sleeving process is provided. In one aspect the product has a tapered cuboidal shape having four converging sides with which the polymeric film sleeve maintains contact. In another aspect two polymeric film sleeves are applied perpendicular to one another.

Abstract: The present invention relates to a container (10) containing a liquid product. The container enables the venting of the liquid product by a venting means. The venting means allows the passage of gases between the interior and the exterior of the container when the pressure inside the container differs from the ambient pressure. The venting means is permeable to gases, but impermeable to the liquid product. The liquid product comprises particulate solids selected from the group consisting of carbonate, percarbonate, perborate and mixtures thereof. The size of the particulate solids is not greater than 400 &mgr;m.

Abstract: A cell system has one or multiple burstable enclosures or closed cells which contain an active composition, such as a fluid or solid (including powdered) product, preferably a liquid product, which is released therefrom when the enclosures or closed cells are ruptured. Each enclosure or cell is provided with a flow control which controls the direction and flow of the composition outwardly of the enclosure or cell when the enclosure or cell is ruptured. The flow control is formed by a film covering one side of an enclosure or cell with the film having a cut-out portion forming a flow control window. The composition can be a face cleaning lotion or cream, a disinfectant, a household cleaning composition, a perfume, a polish or a medicament.

Abstract: The present invention relates to a process for producing a four sided seal sachet (10) filled with a pre-set volume of flowable material, the sachet being made from a flexible film comprising a metallocene catalysed resin, the sachet having a length L (11) between transverse seals (71) and a width W (12) between longitudinal seals (70), whereby the pre-set volume of flowable material is of more than 0.525×W2×L/&pgr;, so that leak-free seals are provided.

Abstract: The present invention relates to a container, or a cap for a container for viscous liquid products. The container or the cap comprises a venting element. The venting element allows passage of gases between the interior and the exterior of the container when the pressure inside the container differs from the external ambient pressure. The container or cap further includes a control feature which controls the phase separation of the product splashed onto the membrane.

Abstract: The present invention is a venting cap (1) with a hole (4) and a semi-permeable membrane (7). The membrane is fitted in a housing (6) of particular dimensions which is in turn fitted in a protrusion (5) corresponding to the hole in the cap.
