Abstract: A composite material made of a plastic base material with particles or fibres of renewable raw materials such as wood fibres, abaca, cellulose fibres, regenerated cellulose fibres, hemp fibres or flax fibres embedded therein and optionally a bonding agent, also contains a wetting agent selected from a polyethylene glycol with an average molecular weight of 90 to 40,000 and/or a polyvalent alcohol.

Abstract: A bag, consisting of a single-layer or multi-layer bag wall, which is bonded to form a tube (1) and, at least at one end, has a bottom (4) which is suitable for filling with charge through a filler of a bag-filling machine, is folded and bonded and is realized with a valve opening (13), and said bag wall being designed to dissolve in a moist environment thereby releasing the charge, makes complete dissolving of the bag wall (2) possible even in the region of the bottom (4) which is provided with the valve opening (13), characterized in that the bonding of the bottom (4) is effected using a dextrin adhesive.

Abstract: A foil made of two plastic films and an adhesive layer laminating the two films together, wherein the first plastic film has a first side and a second side and comprises punctures therebetween. The foil is of a dual peel-seal type such that the first plastic film realizes a first peel-able seal within the foil at its first side in the form of an adhesion peel seal in an open state and/or in the form of a cohesion peel seal in a sealed state, and wherein the adhesive layer leaves open the punctures such that gas can penetrate through the punctures in-between the two films towards the first peel-able seal.

Abstract: In a reclosable bag (20) a zipper (Z) is provided on the inner surfaces (50) of the plastic film and the two parts of the zipper (Z) are fixed on the opposite inner surfaces (50) of the bag (20), wherein the zipper (Z) is connected to the inner surface (50) of the plastic film in such a manner that between the welded regions (12, 14) between the zipper (Z) and the inner surface (50) of the plastic film, recesses (15, 13) are left free in the longitudinal direction of the zipper (Z) to form a seal-free longitudinal channel and in the transverse direction of the zipper (Z) to produce free air or steam passage openings at defined distances between the zipper (Z) and the inner surface (50), through which openings a passage of steam is possible, wherein ends of the openings facing the interior (60) of the bag (20) are larger than ends of the openings facing the exterior (70) of the bag (20).

Abstract: In a method of manufacture for a packaging film, a pour-hole film strip is supplied to a film web and with its film strip sealing layer is attached to that side of the film web which, when the packaging film is used as prescribed, forms a film inner side of the packaging so that a tensile force can be transmitted via a pull tab in the packaging film to a separating region in the film strip sealing layer and said separating region and an adjoining region of an adhesive layer form a reclosure cooperating with the pull tab.

Abstract: In a method for surface-treating paper, in particular paper printable by ink-jet printing, in which an aqueous solution containing at least one water-soluble salt of a bivalent metal and optionally one or several substances selected from a binder, a pigment, a surface sizing agent and/or a cationic polymer is applied to a base paper containing cellulose fibers and optionally fillers, an optical brightener, retention aids or dyes or pigments, an unsized base paper is formed from a pulp comprising cellulose as a main component, between 0 and 50% by weight, in particular 10 and 30% by weight, of CaCO3 as a filler, and optionally an optical brightener or a retention aid, and the base paper is coated with a liquid surface treatment medium comprising between 1 and 20 kg/t paper of MgSO4 and the paper is optionally subjected to a post-treatment step.

Abstract: A bag, consisting of a single-layer or multi-layer bag wall, which is bonded to form a tube (1) and, at least at one end, has a bottom (4) which is suitable for filling with charge through a filler of a bag-filling machine, is folded and bonded and is realized with a valve opening (13), and said bag wall being designed to dissolve in a moist environment thereby releasing the charge, makes complete dissolving of the bag wall (2) possible even in the region of the bottom (4) which is provided with the valve opening (13), characterized in that the bonding of the bottom (4) is effected using a dextrin adhesive.

Abstract: To empty a bag which has at least one cross bottom (4) which is covered with a bottom cover sheet (18) and which has an essentially rectangular shape and is glued together out of corner tucks (11) angled from narrow sidewalls via folding lines and out of bottom flaps (12) angled from wide sidewalls via folding lines (13, 14), there is provision, according to the invention, whereby the bottom cover sheet (18) is drawn off, starting from a narrow sidewall, from the respective corner tuck (11) and from part of the adjoining bottom flaps (12), whereby the bottom flaps (12) are torn on the far side of the corner tuck, transversely with respect to their free edges, as far as the adjoining wide sidewall, in order to separate a part (12?) of the bottom flaps (12), and whereby the separated parts (12?) of the bottom flaps (12), together with the corner tuck (11), are bent, by being folded up about the folding lines (13, 14, 23), into a pour-out channel (24), via which the emptying of the bag contents takes place.

Abstract: A multilayer bag includes at least one outer paper layer and at least one inner paper layer and a synthetic layer located between the outer and an inner paper layer. On the longitudinal side of the paper bag, an overlap of the outer paper web and a partial overlap of the synthetic web is provided, and the outer paper web is partially adhered to itself in the region of overlap.
