Definitions

• the present invention relates to a mineral wool product package, wherein mineral wool is rolled up to its desired size and wrapped in a packaging material which, at least in the package's end face regions, has been made at least partially sealed.
• rolled-up mineral wool products e.g. mineral wool mats
• a plastic packaging material such that the packaging plastic is interposed between the end of a rolled-up mineral wool product's outermost layer and an underlying layer of mineral wool in such a way that, in the rolled-up product, the packaging plastic extends over an appropriate distance, e.g. over 15 cm, from a lengthwise-of-the package running edge of the roll product's outermost layer in between said layers, and thereafter the packaging plastic is wrapped around the rolled-up product in at least a single layer.
• the packaging plastic has been thereafter melted, during the manufacturing process, to the ends of a product roll, which is why the packages have been difficult to open at the time of use.
• the use of a knife or a similar tool has been necessary for opening the packages, but the opening process has still been difficult.
• plastic as a material is combustible, i.e. increasing the fire load.
• the delivery of plastic to its ultimate worksite increases a fire hazard at the worksite.
• An example of worksites, at which a fire hazard is constituted by plastic is e.g. shipbuilding and in paper and pulp industry it is caused by plastic ending up in a digester along with chips.
• packaging plastic can be ignited by a welding spark during an installation process.
• a package according to the invention is characterized in that the packaging material consists of a plastic which, in order to hold the package together, is made in the package's end face regions at least partially sealed by melting it at each opposite end face of the package, and that the packaging material has been formed with at least one perforation in a circumferential direction of the package.
• the at least one perforation is placed in the vicinity of at least one end face of the package. Still more preferably, there are two perforations and those are placed in the vicinity of either end face of the package.
• the packaging material which preferably consists of a plastic, has its outermost layer in the vicinity of its edge extending in a longitudinal direction of the package, at least over its section present between the perforations, at least in spots, or even continuously over its entire breadth, i.e. lengthwise of the package, bonded firmly to an underlying layer of packaging material.
• the mineral wool product can be e.g. a roll-up mineral wool mat provided with a mesh or glass fabric.
• a mineral-wool containing package of the invention is opened by tearing at least one perforation at least substantially apart, after which the product can be removed from the package.
• the packaging plastic in the package end face regions is made at least partially sealed by melting it at each opposite end face of the package or, preferably, when additionally the packaging material has its outermost layer in the vicinity of its edge extending in a longitudinal direction of the package, at least over its section present between the perforations, at least in spots, or even continuously over its entire breadth, i.e.
• the product package is opened by tearing the section of packaging plastic existing between the perforations in a circumferential direction along the perforations apart and away from the product, after which the plastic caps left on the product's end faces are removed at once or later, e.g. at a worksite.
• fig. 1 shows a completed package for a product of mineral wool, in a side view
• fig. 2 shows in a perspective view a process of opening the package along a central section b of the packaging material
• fig. 3 shows in a side view a process of opening the package from its ends.
• the breadth of a product/product roll is 900 mm (a+b+a in fig. 1) and that of a packaging material is 1300 mm.
• the product 1 is in this example a rolled-up rock wool mat, one side of which is reinforced with a metal mesh, and the packaging material 2 consists of a plastic. Such a product is presented in fig. 1.
• the packaging plastic is perforated at a distance of 250 mm from either face, with a 4 mm hole and a 2 mm web, in a longitudinal direction of the packaging plastic.
• the perforation process is carried out on-line.
• the mineral wool product 1 is rolled up (on-line) and the perforated packaging plastic 2 is interposed between the end of an outermost mineral wool layer of the rolled-up mineral wool product 1 and an underlying mineral wool layer, such that the plastic extends advisably over a distance of about 150 mm from a lengthwise-of-the package running edge of the rolled product's outermost layer in between said layers.
• the packaging plastic 2 is cut in a lateral direction of the plastic.
• This cut-off end of the plastic is here referred to as "a trailing end" of the plastic (while the plastic's end, which is interposed between the end of an outermost mineral wool layer of the rolled-up mineral wool product 1 and the underlying product layer, can be referred to as "a leading end” of the plastic). Because the trailing end of the packaging plastic 2, i.e.
• the one of the two ends of the plastic which is the last of these two to be wrapped around the product in other words the end which after the wrapping process is the outermost one of these two ends, has at this point an adhesive applied to its inside, it can be bonded, for rounding up the wrapping process, firmly to the underlying, second outermost plastic layer.
• the furthest marginal area of the packaging plastic's trailing end does not have adhesive applied thereto in order to make the package easier to open by pulling on this adhesive-free skirt available for gripping.
• the plastic sections surpassing the rolled-up product's 1 end faces are fused for establishing package end faces 5 sealed at least to such a degree that the product is certainly able to retain its coherence within the plastic package.
• the package end faces 5 may include e.g. one or even several holes.
• the purpose is to block the access of dirt or moisture to the product, it will be advisable to melt the plastic to a totally sealed condition at the end faces 5.
• the circumferentially directed perforations 4, 4' are located at a distance (a) of about 50 mm from the package's 3 end faces.
• Fig. 1 depicts a perforated package 3 as described above.
• the package 3 can be opened by removing the melted end face plastic of the package or, in other words, by removing the above-mentioned end caps 5 along the perforations 4, 4' from both ends without tools, while the prior art method requires the use of a knife.
• Such a novel way of opening is illustrated in fig. 3.
• the package 3 can be opened as shown in fig. 2, prior to the delivery to a final worksite, by pulling on the above-mentioned adhesive-free ready-to-grip skirt of an 800 mm broad plastic section b, which remains between the packaging plastic's 2 two co-directional perforations 4, 4', the packaging plastic off in the direction of an arrow v, such that the end face plastics 5 are left in place for holding the product roll together for the duration of a final transport.
• the harmful delivery of plastic to a final worksite for example, a fire hazard in shipbuilding
• the ending up of plastic in a digester along with chips can be reduced.
