Abstract: A method of producing a packaging laminate (10) in which a web is provided with through-going holes (2) which are covered on one side with a first outer layer (3) on the one side of the web and with a second outer layer (4) on the other side of the web in such a manner that the first and second outer layers (3 and 4) are permanently sealed to one another within the regions of the opening contour of the through-going holes. In order to ensure the permanent seal between the two outer layers (3 and 4), the web is subjected, after application of the first outer layer but prior to application of the second outer layer, to so-called flame-treating whereby accessible parts of the first outer layer within the regions of the through-going holes (2) are activated or polarized by means of one or more gas flames directed at the other side of the web.

Abstract: A packaging laminate includes a core layer (or web) with through-holes covered on one side with a first outer layer, and on another side with a second outer layer, such that the first and second outer layers are sealed to each other within the through-holes. To provide a permanent seal between the outer layers, the web can be flame-treated to activate or polarize parts of the first outer layer within the through-holes.

Abstract: A low scalping laminate material for a container for food packaging includes a core layer of paper or paperboard, a polymeric coating applied to one side of the core layer and a combination of layers disposed on an opposing side of the core layer. The combination of layers includes a first barrier layer disposed adjacent the core layer, a first tie layer adjacent the first barrier layer, a second barrier layer adjacent the first tie layer, a second tie layer adjacent the second barrier layer and a second polymeric coating adjacent the second tie layer. The second polymeric coating is configured for a food contacting surface. The first and second barrier layers are formed from an admixture of an aromatic polyamide resin and polyamide 6, and the first and second tie layers are formed from one of a modified polyethylene and a polyolefin. A carton formed from the low scalping laminate is disclosed.

Abstract: Press roll (10) for a laminating machine for producing a packaging material which comprises a carcass layer (42) consisting of paper or carton, and which carcass layer exhibits crease lines, through holes, openings or slits (43), which carcass layer exhibits, on one of its sides, a barrier layer (23), a plastic lining (31) which is arranged outside the barrier layer, and film (25) of laminant thermoplast which is arranged between the carcass layer and the barrier layer, with the said press roll (10) exhibiting a circular-cylindrical jacket surface having a facing (40) consisting of an elastic material. According to the invention, the said facing (40) comprises sections (44, 44′) in the jacket surface, which sections exhibit local deformation ability in relation to the surrounding facing (40, 44). The invention also relates to a method for producing packaging material and to packaging material which has been produced using this method.

Abstract: A catering cart whose height is substantially greater than its width and its length, and particularly a catering cart for use in confined spaces, such as in the aisles of passenger aircraft and railway diners. The cart is supported on four wheels, at least two of which are castor wheels, and has an access opening on one side thereof. Two such carts can be mutually coupled with the sides opposite the access openings facing towards one another, with the aid of mutually identical coupling devices on each respective cart. Each of the coupling devices can be operated from that side of the cart which presents the access opening. The opposite side of the cart includes an overhang such that prior to coupling the carts together a gap is provided in the bottom region of the back-to-back cart combination in the vicinity of the coupling devices, this gap being brought to zero when the carts are coupled together, such that the carts will be supported in a sloping position solely by the outer pairs of wheels.

Abstract: A light transmitting plate member for illuminated signals, illuminated tas or similar illuminated flat items and intended for uniform diffusion of light from a light source positioned at a side edge of the light transmitter which has a flat side and an opposing side which has a gradual slope. The plate member has a reduced thickness in the direction away from said side edge, with the opposite sides being produced with optically smooth surfaces as the light transmitting plate member includes transparent and light transparent material with specific optical properties. The side with the gradual slope is provided with a number of angled divisions which are defined by transverse divisional lines which run parallel to the side edge and which are positioned with either uniform intervals or with graded intervals which are reduced in the direction receeding from the side edge.
