DK 2020 00077 U1 1 Guide foil with paper bag Area of manufacture The present article is made regarding a bag web which is configured to be passed through a filling station.
The bag web may comprise a constant passage of a guide material which is configured to be passed through the filling station.
The guide may be connected to one or more bags of a bag material and to a bag opening.
The bag material is a different material than the guide material.
Background of the production Effective filling of bags with contents or articles on an industrial scale is an important technical area.
Filling stations have been developed for years, which have been configured for efficient operation.
Bags often have a purpose in addition to arranging the division of content and articles for delivery.
Bags can also protect the content or articles and enhance or even make delivery or presentation of the content possible.
Such filling stations and bag tracks have been developed in parallel and mutually adapted for efficient use.
It has been shown that polymer, as a guide and an operational interface with a filling station, can provide both efficient handling and operation.
It has also been shown that polymers and the like are very useful as a guide on a bag track, as they are flexible, ie. durable and durable.
Webs or bag webs are therefore successfully produced in the same material.
However, it has been found that bags with a material which is optimized and e.g. with an automatic or semi-automatic process has a negative impact on the environment upon disposal.
Purpose of the production There is therefore a need to improve and provide alternative solutions.
There is a need to provide a durable bag which can be disposed of with a low environmental impact.
DK 2020 00077 U1 2 There is also a need to provide a bag that can be filled and e.g. adhere to automatic or semi-automatic industrial processes, to the provision of large quantities of environmentally friendly bags.
At the same time, there is a need to secure and maintain existing efficient production systems, ie. efficient filling stations, which are automatic or semi-automatic.
Description of the invention The present invention has been made using the prior art described above, and the object of the present invention relates to products and apparatus as follows.
In one aspect, there is a bag path which is configured to be passed through a filling station. The bag web may comprise a constant guidance of a guide material which is configured to be guided through the filling station. The guide may be connected to one or more bags of a bag material and to a bag opening. The bag material is a different material than the guide material.
This ensures that existing guide configurations and assemblies can be maintained and used at existing filling stations, while enabling bag materials with a reduced environmental impact to be provided.
Furthermore, bags made of more environmentally friendly materials than guide materials can be filled in an optimized way in an automatic or semi-automatic process, even on an industrial scale.
A further advantage is obtained by providing durability; i.e. a bag which is durable during the filling process and when used as a e.g. a bag, and a bag that can be disposed of with low environmental impact. The bag can be filled and through the filling process withstand an automatic or semi-automatic industrial process and thereby provide a large number of environmentally friendly bags.
An additional advantage is that highly efficient filling systems and machines can be used
DK 2020 00077 U1 3 and maintained, and thus existing production systems can be used, ie. efficient filling stations that are automatic or semi-automatic. The guide material can be flexible, ie. stretchable material that can be used in existing filling systems.
The bag material can be environmentally friendly, e.g. paper or aluminum. In one embodiment, the bag web bag material is of paper. The paper used may vary depending on the need. The paper may be coated with a protective layer.
The paper can have a density of 30 to 150 g / m or even to 250 g / m 2. The paper may be laminated or in a layered structure one of, for example, 25 g / m 2 and one of 50 g / m 2. The paper can be partially or fully coated paper. In the case of fully coated paper, the coating can be 18-22% by weight. The bag material of the bag web can also be aluminum or aluminum foil. In one embodiment, the guide material of the bag web is polymer or plastic.
Guide material may be a polymer such as polypropylene or polyethylene. One skilled in the art will appreciate the differences and be able to select configurations that provide the appropriate flexibility and durability for existing filling stations. Such polymers are available with different degrees of sealing and lukewarmness as well as qualities which are suitable for specific packaging and filling purposes. The polymers are available with different degrees of sealing ability, temperature resistance and have suitable mechanical properties with regard to sufficient abrasion resistance / perforation resistance and a balance between flexibility and stiffness.
In one embodiment, the guide material is a polymer and the bag material is paper. This specific combination of polymer, such as polypropylene or polyethylene, and paper provides efficient production, on an industrial scale, of environmentally friendly bags
DK 2020 00077 U1 4 with content which bags can be disposed of or recycled. For example, a bag of paper with a density of 60-70 g / m produced and as few additives as possible, such as less than 5% by weight.
In one embodiment, at least one or more of the bags may be attached to the guide by means of a splice. The bag material may be prepared with an imprint defining a splice path and where the bag and guide may be connected along at least a portion of the splice path.
A splice can be a way to connect the guide and the bag material. The splice can be made by welding, including heat welding, or by gluing with glue or other means of gluing. Other ways can be by sewing.
In one embodiment, the imprint on the bag of the bag web may be made of lacquer or glue.
In one embodiment, the guide may be connected to the one or more bags on the inside of the one or more bags. The connection may be located substantially along the bag opening of one or more bags of the bag web.
It is understood that a bag has an inside and an outside. Attaching or connecting the guide material to the inside of the bag reduces the risk of tearing or damaging a bag or bag path during the filling process.
In one embodiment, the paper is pure paper which does not comprise more than a certain% by weight of additives, such as e.g. less than or equal to 5% by weight, 20% by weight or 50% by weight.
By clean paper is meant a pure pulp part. The pulp can be a so-called virgin pulp or recycled pulp.
The additives may be additives mixed into the paper or provided as fully or partially coated paper.

DK 2020 00077 U1 6 Detailed description of the production Fig. 1 illustrates a known system with a filling station 80 for filling a bag web 10. The filling station 80 may be a manual filling station 80, or a semi-automatic filling station 80, or an automatic filling station 80.
The system is designed to fill bags 30 from a roll of bag web, the bag web being made of a plastic material. The person skilled in the art knows which plastic materials are used. The characteristics of the plastic materials used are well known, and filling station systems are designed to work with these plastic materials. However, there is a growing need for systems and bag lanes to fill paper bags. The problem is that the current systems are designed for polymer or plastic materials, and the characteristics of paper differ markedly from the plastic materials or polymers used. Paper abrasion resistance is lower than currently used plastic materials. Furthermore, paper cannot undergo the same elastic or plastic deformation as the polymer or plastic. Those skilled in the art know that polypropylene (PP) or polyethylene (PE) is used as the material in the bag web.
If a plastic bag web 10 is replaced with a paper bag web 30, the system would tear or destroy too many of the bags for it to be viable. Thus, a new system must be designed that takes into account the characteristics of the paper, ie. paper restrictions in relation to the currently used plastic materials.
Problems described above are the same when trying to use aluminum, as the system is not designed to handle aluminum. FIG. 2 illustrates the bag web 10 without (2A) and with perforations (2B).
The described bag web 30 can be used in filling systems as shown in fig. 1, even if the bag is made of a non-plastic material, such as paper or aluminum. The final bag 30, which is filled with contents, is a paper bag 30, which is filled on a system designed for plastic bags.
The described bag web 10 comprises a bag web 20 of a guide material which is configured to be passed through a filling station 80, such as but not limited to the filling systems in fig. 1 and 2. The guide 22 is connected to one or more bags 30, which are made of bag material. The one or more bags 30 have a bag opening 34 for receiving contents.
The guide material may advantageously be well-known plastic or polymeric materials currently used in bag webs 30, such as polypropylene (PP) or polyethylene (PE), as the systems are designed with said materials in mind.
In the present embodiment, the one or more bags 30 and the guide 20 are connected to each other along a splice path 38. The connection may be made by heat welding or pressure welding or by any other process capable of to connect the guide material to the bag material.
The individual bags 30 are separated by means of a dividing line, thereby enabling individual movement of the bags. The separation line 40 has a T-shape in the guide 20 to allow some movement.
The one or more bags may have an imprint 36 to enable the connection between the guide 20 and the one or more bags 30. The imprint 36 thereby defines the splice path 38. The imprint 38 may be varnish or glue. It will be necessary to add an imprint 36 if the one or more bags 30 are made of paper with equal to or less than 15% by weight of additives, or equal to or less than 10% by weight of additives, or, preferably , equal to or less than 5% by weight of additives. The need for a pressure 36 increases as the number of additives decreases because the splice strength between the bag 30 and the guide 20 decreases along with the number of additives; the pressure compensates for the weakening of the splice.
A bag material made of paper with a weight% of additives equal to or less than 5% is preferred, as most of the EU has a limit on the amount of additives a recyclable material may contain.
DK 2020 00077 U1 8 The guide 20 may comprise two plastic flaps with one on each side of the bag opening 34 to enable the system to guide the bag web 10. The two plastic flaps can each be folded to form two channels for receiving guide means. The guide 20 may have perforations as shown in FIG. 3B to insert a spigot. The guide 20 may have other means of enabling the guide through a system with a filling station. FIG. 3 illustrates a bag 30 which is disconnected from a bag web 10. The bag 30 will, after being filled with contents, be disconnected from the bag web 10.
The guide 20 is made of guide material. The guide material may be a polymer or plastic, such as polypropylene (PP) or polyethylene (PE). The guide material is not desirable and must be removed. The guide 20 is removed by cutting along a cutting line 42, and the bag 30 is spliced along the backfill splice web 39 below the cutting line 42 to avoid spillage from the now closed bag opening 34. FIG. 4 illustrates the steps to be performed on the bag 30. Those skilled in the art know that the refill splicing can be done before the bag 30 is disconnected from the bag web 10 and / or along the cutting web.
The final bag 30 can thus be made of a material which otherwise cannot be used in current systems for filling bag webs 10, as they are designed to fill bag webs 30 which are made of plastic materials or the like. Since the guide 20 is completely removed from the final bag 30, the purity of the final bag 30 is increased, and thus it is easier to reuse the bag 30. This makes it possible to produce the final bag 30 of sheets of paper weighing 30-65. g / m 2, while having additives equal to or less than 5% by weight. This enables the bags 30 to be recyclable, at least in the EU. FIG. 4 illustrates the splice path 38 seen from the outside (A) and seen from the inside (B) a bag, and seen from above (C) an open bag 30.
DK 2020 00077 U1 9 The special embodiment of the bag web uses standard polymer as the guide and a paper bag made of 65 g / m paper with a thickness of approx. 100 um. The imprint is a polyolefin blend.
FIG. 4A shows the connection between a guide 20, which is made of plastic material, which may be polypropylene (PP) or polyethylene (PE), and a bag 30, which is made of paper material, seen from the outside. The splice path 38 is, in this embodiment, clearly shown as an indentation. FIG. 4B shows the connection between a guide 20, which is made of plastic material, and a bag 30, which is made of paper material, seen from the inside. The splice path 38 is most visible on the left side of FIG. 4B. The plastic material, i.e. guide 20 can be removed at a later time by cutting along a cutting line below guide 20.
FIG. Fig. 4 illustrates a view into the bag 30 through the bag opening 34. The guide 20 is connected to the bag 30 on both sides of the bag opening 34. FIG. 5 illustrates another embodiment of a bag web 10. The bag web 10 is configured to be passed through a filling station 80, in that the bag web 10 comprises a continuous guide 20 of a guide material 22, which is a plastic material. The guide 20 is configured to be passed through the filling station 80. The guide 20 is connected to one or more bags 30 of a bag material 32, which is paper. The one or more bags 30 have bag openings 34 for receiving contents.
The bag path 10 is shown with only two bags 30, but it can in reality be infinite. The person skilled in the art knows that the logo "Schur" is irrelevant to the creation, as the logo has no technical contribution.
