Definitions
- the invention relates to a packaging material made of aluminum and a lid for closing containers, which can be produced from this packaging material.
- packaging material made of aluminum in particular for food or other sensitive packaging material, such as pharmaceuticals.
- the advantage of aluminum as a packaging material is its versatility in processing, as well as the appropriate means of closing, its stability against external influences. For example, foods that are packaged in aluminum packaging material are protected against atmospheric moisture and against the ingress of contaminants.
- the aluminum which is mainly stored in rolls, is further processed by rolling to the desired material thickness. Due to the contact pressure during the rolling process, very thin layers of material are sometimes produced, the separation of which can lead to difficulties.
- lids for closing containers which are usually provided by punching out the roll goods mentioned above. After punching, the aluminum lids are stored in a stack. Before they can be used again, such as packaging food, the lids must be unstacked quickly, with high cycle times required for packaging, particularly in the case of highly sensitive packaged goods, such as dairy products, in order to prevent any contamination from penetrating into the packaged goods.
- the lids due to the relatively low layer thickness of these lids, they adhere strongly to one another, so that the required cycle times during unstacking cannot be maintained.
- the invention seeks to remedy this.
- a packaging material made of aluminum which is characterized in that the tensile strength of aluminum is in a range from 90 to 180 N / mm 2 .
- the invention further relates to a lid for closing containers with a sealing layer attached to the side facing the packaged goods, according to the invention this lid made of a packaging material made of aluminum of the aforementioned type, namely with a tensile strength of 90 to 180 N / mm 2 , preferably 100 to 160 N / mm 2 .
- a tensile strength of 90 to 180 N / mm 2 preferably 100 to 160 N / mm 2 .
- This sketch shows a possible embodiment of the lid 1 according to the invention with a surface-rough coating 2 for closing containers.
- the packaging material according to the invention is, as usual, as a roll would be stored and then brought to the appropriate material thickness, for example to a thickness of 20 to 60 ⁇ m by rolling.
- the aluminum is then annealed.
- This annealing process can be carried out, for example, by means of strip annealing, the aluminum being supplied to the annealing channel in the form of a strip.
- the removal rate and thus the length of time that the aluminum strip stays in the annealing duct are also decisive for the tensile strength generated.
- the annealing process can be carried out, for example, by "coil annealing", the aluminum being introduced into the annealing furnace in the form of the entire roll.
- the aluminum is annealed for a period of 42 hours at 150 ° C and constant temperature.
- the aluminum treated in this way is then cooled in a roll, the cooling process taking place over a period of about 36 hours to about 20 ° C. at room temperature.
- the recrystallization (recrystallization) is only partially effected in the case of semi-hard aluminum, whereas the recrystallization is completely completed in the case of soft aluminum.
- Hard aluminum shows no tendency towards recrystallization.
- the range of semi-hard aluminum is in a range for the tensile strength of 90 to 180 N / mm 2 , with soft aluminum with a scattering range of ⁇ 10 N / mm 2 being below 70 N / mm 2 .
- the tensile strength values of hard aluminum are above a limit of ⁇ 10 N / mm 2 starting at around 190 N / mm 2 .
- the aluminum packaging material produced according to the invention which has a tensile strength in the range from 90 to 180 N / mm 2 , is then further processed, for example, to produce lids for closing containers.
- the roller would be coated at least on one side with a sealing wax.
- the rolled goods are coated on one or both sides with a surface-rough coating.
- this rough surface coating 2 consists, for example, of a point varnish which has been applied to the packaging material 3 according to the invention.
- the rough surface coating can either be provided by printing, ie using appropriately prepared pressure rollers, or by extrusion.
- the surface roughness within the cross section of the lid width in the area of the sealed seam for closing the container is lower than in comparison of the remaining surface area.
- the packaging material can then be punched out in the form of roll goods, as usual, to form cover elements or provided with a predetermined breaking point, as shown as weakening line 5 according to the figure.
- cover elements provided with the weakening lines 5 can be used to close containers, for example for liquid foods, such as drinking yoghurt.
- the adhesive force within the sealing seam is overcome by applying a scribing force, preferably by means of the grip tab 4, so that a pouring opening corresponding to the line of weakness, ie the predetermined breaking point 5, is created. If the lines of weakness are in the form of notches, the partial opening of the cover element takes place in such a way that the cover element is peeled off along the predetermined breaking point 5 during the opening process.
- the opening mechanism can also be initiated by pressing in the lid, so that the partial opening of the container and thus the removal of the food, such as a drinking yoghurt, is also made possible in this way.
- the lid is adequately sealed in the unopened state.
- This is an essential criterion, in particular when transporting containers which are closed with cover elements which have the predetermined breaking point 5.
- the containers are often exposed to vibrations, the lid element having to have sufficient tightness so that the packing material, such as yogurt, does not run out.
- the predetermined breaking point is designed in the form of a perforation in such a way that the packaging material is punched out at a relatively high material depth and therefore no longer withstands shocks, such as during transport, so that the cover element can tear.
- the packaging material is already fragments 5 exposed to high mechanical loads, so that due to the high material hardness cracks can occur when punching or making the notches.
- the packaging material according to the invention made of aluminum, which has a tensile strength in a range from 90 to 180 N / mm 2 , can be used, inter alia, to produce cover elements for food containers, which can be easily converted into one after their manufacture and storage Unstack the stack.
- This ability to unstack can also be increased by providing a surface-rough coating or a surface-rough imprint, so that the cycle times during packaging are further increased.
- a cover element additionally has a predetermined breaking point for the formation of a pouring opening while a food container is being opened, this predetermined breaking point is, despite a line of weakness in the material, impervious to the ingress of moisture, dirt or bacterial contamination, which is particularly necessary when transporting the containers filled with food Criterion is.
