Abstract:
A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.
Abstract:
A laminate structure (20) is provided for forming a package (10), where the laminate structure (20) allows for access openings (50) to be provided upon peeling of the layers (22, 24). The access openings (50) may allow air to be introduced to the contents, such as to cause an exothermic reaction for heating items, or may allow product to be dispensed from the package (10). The laminate structure (20) includes a first layer (22) laminated to a second layer (24) via an adhesive (26), and score lines (30) are formed in the second layer (24) to define plug areas (40) and non-plug areas (45). The plug areas (40) are configured to result in a peel interface line that occurs across a constant ratio of plug areas (40) to non-plug areas (45) along a predefined distance of a peel area of the laminate structure (20). Thus, when the first layer (22) is peeled away from the second layer (24), the peel force needed remains relatively uniform across the predefined distance.
Abstract:
The present invention concerns a method and an apparatus for making mineral fibre products by splitting an incoming primary web, said apparatus comprising a feeding conveyor for providing an incoming primary web of air-laid mineral wool, said feeding conveyor having a first direction of travel; a station for shifting the direction of travel of the primary web by receiving the primary web on a turning table and then transferring the primary web onto a receiving conveyor, where said receiving conveyor has a second direction of travel different to the first direction of travel; wherein a web splitter is provided at the downstream end of said receiving conveyor for dividing the incoming primary web into a first primary web and second primary web and wherein the turning table is shiftable in the first direction of travel.
Abstract:
Die Erfindung betrifft einen Kunststoffgewebeverbund für einen Kunststoffgewebeverbundbeutel mit einem Bändchengewebe (6), einer Außenfolie (7), einer zwischen der Außenfolie (7) und dem Bändchengewebe (6) angeordneten Zwischenschicht (8) aus Kunststoff und einer Schwächungslinie in Form einer Stanzlinie (1, 1'). Erfindungsgemäß ist das Bändchengewebe (6) entlang der Stanzlinie (1, 1') vollständig durchtrennt, wobei die Stanzlinie (1, 1') in der Zwischenschicht (8) endet und die Außenfolie (7) an der Stanzlinie (1, 1') unversehrt ist. Gegenstand der Erfindung sind auch ein Verpackungsbeutel aus dem Kunststoffgewebeverbund sowie ein Verfahren zur Herstellung eines Verpackungsbeutels.
Abstract:
There is described a method of creating a transparent polymer window (W) with a field of lenses (L) in a security paper substrate (1), the method comprising the steps of (i) providing a security paper substrate (1), (ii) forming an opening (10) into the security paper substrate (1), (iii) laminating a transparent film (5; 5*) onto a first side (I) of the security paper substrate (1) in such a way as to close the opening (10) at one end, and (iv) filling the opening (10) with transparent polymer material (2). In one embodiment, the transparent film (5) comprises a field of lenses (L) and is laminated onto the first side (I) of the security paper substrate (1) in such a way as to form lenses (L) on the first side (I) of the security paper substrate (1) in register with the opening (10). In another embodiment, the field of lenses (L) is replicated into the transparent polymer material (2) applied in the opening (10) in such a way as to form lenses (L) on a second side (II) of the security paper substrate (1), opposite to the first side (I), in register with the opening (10). Also described is a device designed to fill the opening (10) formed into the security paper substrate (1) with the transparent polymer material (2) and a processing machine comprising the same.
Abstract:
Methods, plate elements and heat/enthalpy exchangers. a) perforating an unformed plate element with defined outer dimensions in any desired area and in any desired dimension; b) covering at least one side of the unformed plate element with a thin polymer film with latent energy exchange characteristics and; c) forming the plate element into a desired shape and a pattern of corrugations and/or embossing. The operations b) and c) may be performed in a different order. For instance, when the plate element is made out of plastic, b) may be performed before c) whereas, when the plate element is made out of aluminum (or plastic), c) may be performed before b). Operations a) and/or b) and/or c) may also, in certain embodiments, be combined.
Abstract:
A break seal is provided which comprises a foam sheet and a film layer. The foam sheet comprises a center hole. The film layer is partially scored through the thickness.
Abstract:
There is provided a polyimide layered product with a support which has a smooth surface to enable a sophisticated device to be formed thereon and in which the layered polyimide does not peel off even in a high-temperature process on device formation, and furthermore, the polyimide layered product can be peeled off easily from the support after the device is formed on the polyimide layered product. By preparing a polyimide film with a face at the support side and subjected to a surface treatment; subjecting at least one of a face of the support and the face of the polyimide film which are opposite to each other to a patterning treatment using a coupling agent to form a satisfactorily bondable part and an easily releasable part which differ in adhesion/peel strength; subsequently, superposing the support and the polyimide film to be subjected to a pressurizing/heating treatment and to be bonded to each other; subjecting the surface of the polyimide film to an organic alkali treatment; and then, applying a polyamic acid solution free from a slip agent ingredient, drying the coating film and imidizing the film, a layered product having a structure of at least three layers in which at least one layer contains a slip agent material and both surface layers have no slip agent material is produced.
