Definitions
- the invention relates to a flat packaging element for use in the manufacture of a packaging, wherein at least a first surface of the packaging element, a tendency tendency reducing structure is arranged, and a method for
- the invention relates to a packaging with a packaging element and a method for producing a packaging.
- Processing machine to be supplied wherein the processing machine must separate the blanks before use. This is the case, for example, with adjacent sealable film closure lids for containers, commonly referred to as sinkers. When singling it can be a so-called
- Glass effect come, in which two adjacent blanks adhere to each other and thus two or more blanks are fed simultaneously to the processing machine, which leads to the production of rejects and can also
- the subject invention has the object to provide a novel packaging material, with which these and other disadvantages are overcome.
- this object is achieved by a packaging element of the type mentioned, in which the structure consists of a removable in a procedural removal measure material, the removal measure is applicable to the finished and possibly filled with a product packaging.
- packaging elements can be produced in which the advantages of the structure in production can be utilized. After that, the structure can be removed by applying the removal measure so that it no longer exists from the customer
- each sequence of process steps which is executable on the packaging, and without significantly affecting the product and / or the packaging to a distance
- the removal measure may in particular comprise dissolving the structure with a solvent, in particular with water (hot or cold) and / or water vapor, but the term is not limited thereto.
- the structure is adapted to the respective product and the respective production method, wherein the removal measure advantageously during the
- an inner surface facing the product, or an outer surface facing away from the product may be referred to as a "first surface” depending on where the structure is applied.
- both inner and outer surfaces may be provided with the structure be.
- the structure may consist of a removable by the removal measure, in particular dissolvable, softenable and / or degradable material.
- the structure can be dissolvable in the product.
- the quantity and type of material of the structure are adapted to the product so that the product quality is not affected. If necessary, the
- the structure can be printed by means of a printing process on the first
- the structure may be, for example, a generate defined roughness on the surface, which reduces a tendency to stick
- the pattern such as a regular arrangement of slightly raised structural points, act as a spacer, which prevents a glass pane effect and thereby reduces the adhesion tendency.
- the pattern may have, for example, a regular or irregular arrangement of dots, geometric figures and / or logos. Matching the pattern to an underlying print image is generally not required because the pattern is removed before the customer sees it.
- Areas such as the seal areas can not or should not be removed, so that it is still recognizable there for the customer.
- the material of the structure may be food safe, which allows the use of the invention in the food and animal food sector.
- the structure may advantageously comprise one or more materials selected from a gumming, for example in the form of a water-soluble polymer, starch, in particular potato starch, wheat starch, rice starch or corn starch, gelatin, sugar, salt, in particular table salt, polyvinyl alcohol (PVOH ), Wax, in particular beeswax or Kanauberwachs, or mixtures of these
- a gumming for example in the form of a water-soluble polymer, starch, in particular potato starch, wheat starch, rice starch or corn starch, gelatin, sugar, salt, in particular table salt, polyvinyl alcohol (PVOH ), Wax, in particular beeswax or Kanauberwachs, or mixtures of these
- the materials may be processed for purposes of application in a liquid state and then dried, with appropriate solvents,
- the structure of one of these materials can be at least one
- the term "at least for the most part" in the context of the present disclosure encompasses substances which contain the respective material in a volume and / or weight proportion which exceeds the volume or weight fraction of any other material in the substance.
- fillers may be added to the material of the structure.
- the fillers are added, for example, to another material called a binder, wherein the (weight) proportion of the fillers optionally the proportion of
- Binders can also exceed, provided that the function of removability is maintained.
- materials may be used which are among those for
