Definitions

  • the present invention relates to a paper, in particular for the preparation of foods by heating, comprising a proportion of cellulose fibers and a proportion of thermoplastic, suitable for food contact synthesis staple fibers, and a bag, a shaped body and a use of the paper.
  • the DE 203 06 078 discloses a filter material based on a long fiber paper comprising a blend of fibers of cellulose and polymer fibers.
  • polymer fibers in particular polypropylene is used.
  • Such a filter material is usually only up to temperatures of about 100 ° C to 150 ° C resistant because the polymer fibers would melt at higher temperatures. Therefore, the filter material can be used for infusion drinks, a use at higher temperatures is not provided.
  • baking pad known, for example, consists of baking paper.
  • Such baking papers can also be provided with a silicone coating so that they do not adhere to food.
  • the use of baking papers for the preparation of food is known and has the disadvantage, however, that they are only available in leaf form, even if a certain profiling can be obtained via embossing. Such baking papers are therefore used only as a pad or insert.
  • Foil bags are also known for storing food ( DE 20 2009 002 030 ), which may also consist of a laminate of a plastic film and paper (EP 2 676 898 ).
  • the use of plastic film is not very popular for the food sector because of the typical plastic appearance, especially if a preparation in the oven is to take place. Then there are concerns that the plastic content of the packaging contaminates the food, even if it is heat resistant even at temperatures of more than 200 ° C.
  • a paper for the preparation of foods by heating which comprises a proportion of cellulose fibers and a proportion of thermoplastic, suitable for food contact synthesis staple fibers, wherein the synthetic fibers are made of a material whose melting point is at least 200 ° C.
  • the paper can be shaped, welded and / or sealed.
  • the paper can be used to prepare food in the oven, since the synthetic fibers correspondingly have a high melting point of at least 200 ° C, in particular at least 220 ° C.
  • a paper in the sense of the present application can consist of a mixture of cellulose fibers and thermoplastic synthetic staple fibers, the term "paper” also being used if, according to the definition of EDANA, a nonwoven fabric is present due to the proportion of the thermoplastic synthesis staple fibers. For the present application, a differentiation between paper and nonwoven fabric is not necessary, so that a paper is present even if only a small proportion of cellulose fibers is provided.
  • the paper is thermoplastically sealable and / or weldable.
  • the paper can be further processed in a simple manner, for example for the production of bags or other objects. At the joints then the paper can be stacked and sealed or welded.
  • the proportion of cellulose fibers is greater than 30 wt .-% based on the total weight, in particular greater than 50%.
  • the proportion of synthetic fibers may be greater than 15 wt .-%, in particular greater than 25 wt .-%, based on the total weight of the paper.
  • the paper consists essentially only of cellulose fibers and synthetic fibers.
  • the paper can preferably be made wet laid.
  • the elongation at break of the paper according to the invention is more than 1%, in particular more than 1.5%, according to DIN EN ISO 527. This ensures a safe packaging of food.
  • the cellulose fibers can also be ground particularly finely for papermaking, for example with a length of less than 1 mm, so that due to the choice of the degree of grinding, the paper produced is translucent.
  • synthetic fibers plastics with a high melting point of over 200 ° C, in particular more than 220 or 240 ° C, are used, wherein the synthetic fibers of materials from the group PTE (polytetrafluoroethylene), PET (polyethylene terephthalate), PSU (polysulfone), PEEK (Polyetheretherketone) PA6 (polyamide 6), PA66 (polyamide 66) or mixtures thereof.
  • PTE polytetrafluoroethylene
  • PET polyethylene terephthalate
  • PSU polysulfone
  • PEEK Polyetheretherketone
  • PA6 polyamide 6
  • PA66 polyamide 66
  • the basis weight of the paper is preferably between 35 to 150 g / m 2 , in particular 50 to 120 g / m 2 .
  • the paper has a sealed seam, wherein the seal seam strength according to DIN 55529 more than 4 N, in particular more than 5 N, is.
  • a pouch for storing or preparing foodstuffs can be provided with the paper according to the invention.
  • a shaped article can be produced by the paper, for example by a stamping or drawing process, for example to produce a baking mold.
  • the paper according to the invention can be used in particular for the preparation of foods, in particular by heating.
  • FIG. 1 a bag 1 or a container is shown, which is formed from a bag body of two superimposed layers, which are connected to each other at opposite longitudinal sides by a strip-shaped sealing layer 5. At a front edge a bottom fold 4 is provided, which connects the two layers together. At the opposite side of the bottom fold 4 a bag opening 3 is formed for filling the bag 1.
  • bag 1 ' is provided instead of the bottom fold 4, a further sealing edge layer 4' in the bottom region, so that the two layers on three sides via strip-shaped edge sealing layers 4 'and 5 are fixed to each other.
  • FIG. 3 a plurality of mutually adjoining bags 1 "are shown, which are each formed from a bag body 2, which connects via sealing layers 5 on the longitudinal sides and a sealing edge 4" in the bottom area two layers with each other, which are designed to be open on a bag opening 3.
  • Two adjacent bag bodies 2 are held together in the region of a longitudinal sealing layer 5 via a perforation and can be detached by severing the perforation 6.
  • the bags 1 can be coiled up on a roll and then torn off by the user.
  • the bags 1,1 'and 1 are made of paper containing a proportion of cellulose fibers and a proportion of thermoplastic, suitable for food contact synthetic fibers, these synthetic fibers are made of a material whose melting point is at least 200 ° C.
  • cellulose fibers In particular, vegetable fibers, wood, pulp or other cellulosic substances are used.
  • the synthetic fibers are preferably synthetic staple fibers with a length of between 1 mm and 20 mm, preferably 4 mm to 8 cm. If necessary, the synthetic fibers can also be ground smaller than 1 mm.
  • the material of the synthetic fibers is selected from the group consisting of PTFE, PET, PSU, PEEK, PA6 and / or PA66, the synthetic fibers being mixed with the cellulose fibers to ensure continuous material properties.
  • the paper according to the invention can be sealed or welded by the proportion of thermoplastic synthesis staple fibers, so that the sealing layer 5 manages without adhesive.
  • the cellulosic fibers and synthetic staple fibers may have substantially the same thickness and length, for example in a tolerance range of +/- 20%.
  • the synthetic fibers preferably have a temperature resistance of -20 ° C to over 200 ° C, so that in the entire area a storage or preparation of food is possible.
  • the paper has a basis weight between 35 to 150 g / m 2 and can be coated uncoated if necessary or one or both sides, for example with silicone.
  • the elongation at break of the paper is greater than 1.5% according to DIN EN ISO 527 and the tear strength of the paper is greater than 15 N / mm 2 .
  • the strip-shaped sealing layer 5 may have a seal seam strength of greater than 5 N.
  • FIGS. 4A and 4B a modified embodiment for the use of the paper according to the invention is shown.
  • a sheet-shaped paper 10 is inserted into a pressing device with a die 11 and a male part 12 and then reformed by pressure, optionally with the application of heat.
  • a molded body 10 ' is then produced which is cup-shaped in FIG. 4B and has a height of, for example, more than 2 cm.
  • Such a three-dimensional molded body can be used for storing or preparing food, for example in the oven.
