In deep-drawing packaging, two types of flat sheets, a lid and a bottom material, are used, the bottom material is molded into a container shape according to the mold, food is put into this molded part, and then the molded container is opened. The basic principle is that the cover is covered with a cover material, vacuumed or replaced with gas, and heat sealed.
That is, the feature of deep drawing packaging is that the bottom material is processed into a container shape by deep drawing, but when a transfer sheet coated with a transfer agent layer such as seasoning and flavoring agent is applied to this deep drawing packaging, In this deep drawing process, a stretching load is applied to the molding part of the sheet, so the transfer agent layer applied to the sheet cannot follow the stretching load and peels off or cracks, so that the seasoning etc. can be transferred reliably to the food surface. There was a problem that transfer failure occurred.

In order to prevent this, for example, a pigment layer is provided via an edible plasticizer layer capable of absorbing stress, such as the packaging material of Patent Document 2 on the premise of stress in the shearing process. A countermeasure is required.
Further, in the transfer type food packaging material, when the base sheet is a synthetic resin, in order to apply the pigment, as shown in Patent Document 1, a fiber material layer having water absorbency such as paper and nonwoven fabric is used. If it is not provided on the synthetic resin layer, there is a problem that it is not easy to sufficiently retain the dye component.

  The present invention is a technology for applying a transfer packaging material comprising a heat-sealable synthetic resin base material to deep-drawing packaging, and without transferring or cracking the transfer agent layer and transferring the food additive to the food surface satisfactorily. As an objective.

  As a result of earnest research centering on the binder used in the transfer agent layer of the above-mentioned Patent Documents 1 to 7 in applying the transfer-type food packaging material to deep drawing packaging, the present inventors have found that cellulose derivatives, Rather than using a specific component such as silicon or dietary fiber alone, it can be combined and used as a binder, so that even when an external load is applied to the packaging material in the deep drawing process, the transfer agent at the molding site The present invention was completed by finding out that peeling and cracking of the layer from the base material can be suppressed, and that the food additive containing the pigment can be applied to the base material of the synthetic resin without any trouble by using the binder of the specific component. did.

  That is, the present invention 1 is obtained by coating a transfer agent layer on a heat-sealable synthetic resin base material for deep-drawing packaging, and the transfer agent layer contains a food additive and a binder, and the binder described above. Is a transfer sheet for deep-drawing packaging, which is a mixture of at least two selected from the group consisting of cellulose derivatives, silicon dioxide, dietary fiber, and calcium carbonate.

  The present invention 2 is characterized in that, in the present invention 1, the binder is a mixture of a cellulose derivative and calcium carbonate, a mixture of a cellulose derivative and dietary fiber, or a mixture of a cellulose derivative, dietary fiber and silicon dioxide. It is a transfer sheet for drawing packaging.

  Invention 3 is characterized in that, in the Invention 1 or 2, the food additive is at least one selected from a flavoring agent, a seasoning, a pigment, a liquid, an antibacterial agent, a preservative, and an antioxidant. This is a transfer sheet for deep drawing packaging.

  The present invention 4 relates to any one of the present inventions 1 to 3, wherein the weight ratio of the food additive and the binder in the transfer agent layer is such that when the food additive is a flavoring agent, a seasoning, a coloring matter, or a liquid smoke, It is a transfer sheet for deep-drawing packaging, characterized in that additive: binder = 1: 0.01 to 1: 5.

  Invention 5 is characterized in that, in any one of Inventions 1 to 4, the base material is an unstretched synthetic resin sheet, and the tensile elastic modulus is 600 MPa or more at room temperature and 150 MPa or more at 80 ° C. This is a transfer sheet for deep drawing packaging.

  In the present invention 6, a cover material and a bottom material are constituted by the transfer sheet according to any one of the above-mentioned present inventions 1 to 5, the bottom material is formed into a deep-drawn container shape by a deep-drawing packaging machine, and food is placed in the deep-drawn container. It is housed and heat-sealing the opening of the deep-drawn container with a lid, and transferring the transfer agent layer applied to at least the bottom material of the transfer sheet to the surface of the food by heating or moisture action This is a deep drawing packaging type food transfer method.

When the transfer-type packaging material is applied to deep-drawn packaging, conventionally, when the bottom material is deep-drawn, the food additive causes partial peeling or cracking from the base material due to external force during molding. The transfer to the surface did not occur reliably, causing a transfer failure.
On the other hand, in the transfer sheet of the present invention, the transfer agent layer can be flexibly held on the substrate by selecting a composite combination of specific components such as cellulose derivatives, silicon dioxide, and dietary fibers as a binder. Even if the stretching action is applied to the base material during deep drawing, the transfer agent layer smoothly follows the base material to be stretched. Can be suppressed.
Further, when a synthetic resin sheet that is not stretched and has a tensile elastic modulus (room temperature and high temperature of 80 ° C.) having a specific value or more is selected as the base material, the effect of suppressing partial peeling and cracking of the deep-drawn part can be further improved.
Furthermore, since the food additive containing a pigment | dye can also be apply | coated to a synthetic resin base material without trouble by using the binder of the said specific component, the fiber with a water absorption like paper, a nonwoven fabric, etc. like the said patent document 1 There is no need to interpose a material layer on the synthetic resin layer, and productivity is high.
For this reason, when the transfer sheet of the present invention is applied to deep-drawing packaging, food such as ham, cheese, kamaboko, etc. is put into a portion where the bottom material is deep-drawn into a container shape, and the opening of the deep-drawn container is covered with a lid. When sealed with vacuum and heat sealing, food additives such as flavors, seasonings and pigments can be reliably and satisfactorily transferred to the food surface by heating and moisture action.

In the dye transfer packaging material of Patent Document 4, the binder contained in the colored layer discloses at least one selected from calcium carbonate, starches, silicon dioxide, eggshell calcium, shell calcium, and titanium oxide. , Paragraph 17), focusing on the binders of specific Examples 1 to 8 for producing packaging materials, Example 1 is calcium carbonate, Example 2 is starch, Example 3 is silicon dioxide, and Example 4 is a shell. Calcium, Example 5 is starch, Example 6 is calcium carbonate, Example 7 is starch, and Example 8 is calcium carbonate. All of these ingredients are used alone. Absent.
In Examples 5 to 8, shellac as a binding reinforcing agent is supplemented to the binder (paragraph 18).

  In the present invention, first, a transfer agent layer containing a food additive and a binder is applied to a base material of a heat-sealable synthetic resin for deep-drawing packaging, and the specific components combined in combination are combined. Transfer sheet for deep drawing packaging selected as the agent, and secondly, the transfer sheet is applied to deep drawing packaging, and the flat bottom material and lid used for deep drawing packaging are the above transfer sheet. The bottom material is deep-drawn into a container shape, the food is put into the opening of the deep-drawn container, heat sealed with a lid material, and the food additive is transferred to the food surface by heating or moisture action This is a deep drawing packaging type transfer method.

The base material constituting the transfer sheet of the present invention is a heat-sealable synthetic resin sheet used for deep-drawing packaging, and specifically can be used as a flat bottom material and a lid material for deep-drawing packaging, respectively. .
The heat-sealable synthetic resin sheet is a sheet having at least one synthetic resin layer having heat-sealability, and may be either a single-layer sheet or a laminated sheet. In the laminated sheet, one outer layer is a heat-sealable synthetic resin. Layers are placed.
Examples of the synthetic resin having heat sealability include polyolefins such as various polyethylene (PE), polypropylene (PP), ethylene / vinyl acetate copolymer (EVA), and ionomer. Also, by mixing two types of incompatible polyolefin resins, easy opening that can be easily opened by hand can be imparted to the packaging material, for example, a system in which polypropylene is mixed with polyethylene, a system in which polybutene is mixed with polyethylene, etc. Is mentioned.
In the heat-sealable synthetic resin sheet, a sheet in which another kind of synthetic resin layer is laminated on the heat-sealable synthetic resin layer is preferable. Examples of the resin laminated on the heat-sealable synthetic resin layer include various polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA) (for example, nylon (Ny) for the purpose of imparting rigidity and strength to the sheet. )), Polypropylene (PP), polyvinyl chloride (PVC), thermoplastic elastomer, etc. In addition, for the purpose of imparting gas barrier properties, ethylene / vinyl alcohol copolymer (EVOH), metaxylenediamine nylon (MXNy) ), Polyvinylidene chloride (PVDC), cyclic polyolefin (COP), and the like. In the lamination, the adhesiveness between the layers can be kept good by appropriately arranging an adhesive resin layer between the respective layers.
Examples of the layer structure in the laminated sheet include a PA (Ny) / polyolefin (PE, PP) two-layer sheet, a polyolefin / PA / polyolefin three-layer sheet, and a polyester / EVOH / PA / PE four-layer sheet.
In particular, a layer composed mainly of PE in one outer layer from the point of heat sealability, a PA layer in the intermediate layer from the point of deep drawing, and an EVOH layer in the intermediate layer from the point of gas barrier property are formed by coextrusion method. The film-laminated laminated sheet is suitable as the deep-drawn packaging material for food of the present invention. In addition, when using a deep-drawing packaging machine, a roll-wrapped transfer sheet is drawn out and used. Therefore, when a PP layer is disposed on the other outer layer opposite to the heat-sealable synthetic resin layer, It is possible to prevent “back-off” in which the transfer agent applied on the heat-sealable synthetic resin layer side adheres to the reverse side of the sheet, and to improve the rigidity of the entire sheet. Furthermore, when the packaging container filled with food is not subjected to the boil treatment, if the glycol-modified polyester (PETG) layer is disposed on the other outer layer, the transfer sheet can be imparted with good elasticity and transparent appearance without curling.
The base material is a synthetic resin sheet applied to deep drawing packaging, and the transfer process includes moisture transfer and heat transfer at room temperature. Non-stretching is preferred, and the tensile modulus (room temperature, 80 ° C. during heating) is preferably an appropriate value or more.
When the tensile modulus is designed to be 600 MPa or more at room temperature and 150 MPa or more at 80 ° C. (when heated), partial peeling and cracking of the deep-drawn part can be further suppressed, and the transfer pitch in the heating process Can be stabilized. A more preferable tensile modulus is 700 MPa or more at room temperature, more preferably 800 MPa or more, and at 80 ° C., 200 MPa or more, more preferably 250 MPa or more.
However, the tensile elastic modulus of the synthetic resin sheet of the present invention was measured under the conditions of sheet width 5 mm, distance between chucks 300 mm, and tensile speed 5 mm / min using Shimadzu Autograph AGS-X. It is a numerical value obtained from the average value of the measured values in the horizontal direction.
Further, when the inner surface of the synthetic resin sheet on which the transfer agent layer is applied is roughened by corona discharge or the like, the adhesion of the transfer agent layer can be improved.
The transfer sheet of the present invention can be used for both the bottom material and the lid material of deep-drawing packaging. However, when combining a deep-drawn bottom material and a flat lid material, the side of the lid material is deep drawn. Since such stress is not loaded, the laminated body using a stretched film can be selected. As a laminate using a stretched film, for example, a stretched film such as a biaxially stretched polypropylene film, a biaxially stretched nylon film, and an inorganic vapor-deposited biaxially stretched polyester film, and a polyolefin-based film such as a low-density polyethylene having heat sealability And the like laminated. The surface of the polyolefin film may be subjected to corona treatment. When a transfer agent layer is applied to the lid, a transfer agent layer such as a seasoning and flavoring agent can be formed on a heat-sealable polyolefin film, and pigments and dyes for product explanation and advertising on stretched films. Printing can also be performed.

The transfer agent layer applied to the synthetic resin sheet serving as the base material contains a food additive and a binder.
The food additive is selected from a seasoning, a flavoring agent, a pigment, a liquid, an antibacterial agent, a preservative, and an antioxidant, and these can be used alone or in combination.
The above-mentioned seasonings include spice extract, soy sauce, Worcester sauce, miso, grilled meat sauce, garlic, powdered paste, powdered sesame, pepper (black pepper etc.), ginger, chili, nutmeg, paprika, caraway, hatsuka, wasabi, yeast Examples include natural seasonings such as extracts, meat extracts, crab extracts, bonito extracts, sodium glutamate, sodium inosinate, salt, sugar, potato crystals, roasted flour, powdered cheese, butter, margarine, teas, and the like.
Examples of the flavoring agent include smoked flavors, fruit flavors such as bananas, strawberries, oranges and melons, beef flavors, pork flavors, chicken flavors, cut-off flavors, and ume flavors.
Examples of the pigment include natural pigments such as Anato, Kouliang, Sheanut, Turmeric, Monascus, Cacao, Safflower, Gardenia, Cochineal, Chlorella, Spirulina, Caramel, Perilla, Onion, Akane, Edible Red No. 2, No. 3, No. 102, Synthetic pigments such as No. 106, No. 4, No. 5, No. 5, and No. 1 of Blue.
The above-mentioned liquid is a liquid or powdery product that mainly gives a smoked odor and preservability to foods. Zesty smoke (made by Kelly), Chardex, Enbiro (the above two products are red arrow) Etc.).
Examples of the preservative include sorbic acids, dehydroacetic acid, benzoic acid, or salts thereof, protamine and the like.
The antibacterial agent is a so-called freshness-preserving agent, which is less functional than preservatives, such as mustard, wasabi, extracts thereof, antibacterial calcium, polylysine, chitosan, grapefruit seed extract, but is a short-term antibacterial agent. It has a function.
Examples of the antioxidant include polyphenols such as tocopherol and propyl gallate, guaiac fat, L-ascorbic acid, and various flavonoids.

The binder is for carrying the food additive on the inner surface of the packaging material, and is a composite combination of components selected from the group consisting of cellulose derivatives, silicon dioxide, dietary fiber, and calcium carbonate, and at least 2 It consists of a mixture of seeds and more. In this respect, it differs from Patent Document 4 in which Examples 1 to 8 in which similar components are used alone are disclosed.
Suitable combinations of the binder include a mixture of cellulose derivative and calcium carbonate, a cellulose derivative and dietary fiber, a mixture of cellulose derivative and dietary fiber and silicon dioxide, and more preferably a mixture of cellulose derivative and calcium carbonate, cellulose derivative. And a mixture of dietary fiber and silicon dioxide.
Examples of the cellulose derivative include carboxymethylcellulose (CMC), hydroxypropylcellulose (HPC), hydroxypropylmethylcellulose (HPMC), and hydroxyethylcellulose (HEC).
The calcium carbonate is a concept that includes eggshell calcium, shell calcium, and the like.
The dietary fiber is a concept including pectin, glucomannan, alginate, carrageenan, agarose, indigestible dextrin, natural cellulose that is not a derivative, etc., and natural indigestible dextrin is preferable.
As the silicon dioxide, fine silicon dioxide is preferable.

The weight ratio of the food additive to the binder in the transfer agent layer is such that when the food additive is a flavoring agent, a seasoning, a pigment, or a liquid, the preferred weight ratio is food additive: binding agent = 1: 0.01. ˜1: 5, more preferably 1: 0.1 to 1: 2, and the weight ratio varies depending on the food additive selected.
For example, when the food additive is a smoke solution, the preferred weight ratio is: smoke solution: binder = 1: 0.14, and more preferably, the solution liquid: binder = 1: 0.17.
If the binder is less than the proper ratio for food additives, partial peeling or cracking of the transfer agent layer tends to occur during deep-drawing packaging, and if the binder is more than the proper ratio, the ratio of food additives decreases and the flavor is reduced. Etc., and the viscosity at the time of coating the transfer agent layer is increased, and there is a problem that printability (coating suitability) is impaired.
Note that a binding reinforcing agent such as shellac may be supplemented to the binder, but it is preferable to suppress the ratio of the reinforcing agent in order to maintain the temporal stability of the transfer agent.

The present invention 6 is a transfer method in which the transfer sheet is applied to deep drawing packaging, and FIG. 1 is a schematic process diagram of the deep drawing packaging.
An outline of a deep drawing packaging method using a transfer sheet based on FIG. 1 is that a flat transfer sheet constitutes a cover material and a bottom material, and the bottom material drawn from a take-up roll of the deep drawing packaging machine is heated by vacuum forming. It is heated in a molding die in the area and molded into a deep-drawn container. In the filling area, food such as ham, sausage, and cheese is filled in the deep-drawn container and pulled out from another take-up roll in the sealing area. The covered lid material joins the deep-drawn container, the opening of the deep-drawn container and the lid material are heat-sealed by a sealing mold, and the package is cut by a horizontal and vertical cutting device.
As described above, when the lid material is heat sealed to the opening of the deep-drawn container, it is actually evacuated or replaced with gas, but when the transfer sheet is applied to deep-drawn packaging as in the present invention. Vacuum packaging is preferable.
For deep-drawn packaging, it is preferable to apply a transfer agent layer to both the lid and bottom sheets (in FIG. 1, apply to both materials), but apply the transfer agent layer only to the bottom material. However, since the food surface is in direct contact with or close to the inner wall of the deep-drawn container made of the bottom material in a large area, there is no problem in flavoring and flavoring of the food.

The transfer method to the food surface is divided into two methods: transfer by heating and transfer by moisture action. In the moisture transfer, the food additive is transferred from the transfer sheet to the food surface by the moisture of the food itself. The food additive is heated by a transfer heat device provided on the downstream side of the cutting area and is transferred from the transfer sheet to the food surface. Heating is performed by steaming, boiling in water (boil heating), or the like.
The target part to which the transfer agent layer is applied may be applied to either or both of the cover material and the bottom material. In order to impart seasoning and flavor to food from a practical standpoint, at least the bottom is required. It is enough to apply to the material.
Foods to be stored in deep-drawn containers include processed meat products such as ham, sausage, hamburger, meatballs and kamaboko, cheeses, boiled eggs, fried eggs, grilled fish, dried fish and shellfish, raw meat, and raw fish. Sashimi, etc.).

The preparation method of food suitable for storage in this deep-drawn container is briefly described. For example, in the above-mentioned dried fish, fish gills and internal organs such as saury, horse mackerel, and hockey are removed, and after being opened, immersed in salt water to reach the core. When the salt turns, it is prepared by washing out the surface salt, wiping off the moisture, and drying to dry the surface. Cheese, sausage, hamburger will be described in the examples below.
Of these, non-heated foods such as raw meat, raw hamburger, raw meatballs, raw fish, processed meat products, cheeses, dried fish, etc. are made from the transfer sheet that forms the deep-drawn container with the moisture contained in each food. The food additive is transferred to the surface.
On the other hand, for foods that are cooked and sold, such as processed meat products, hamburger, meatballs, grilled fish, boiled eggs, fried eggs, etc., if they are deep-drawn and packaged after cooking, they are transferred by secondary sterilization heating. In addition, when cooking is performed after deep-drawn packaging, it is transferred along with this heating.
In this deep-drawing packaging type transfer method, when a deep-drawn container containing food and a lid material are heat-sealed with a sealing mold, evacuation is simultaneously performed so that the surface of the food adheres to the inner surface of the container. The food additives such as seasonings and flavors are transferred to the food side, but on the other hand, heat sealing is performed without emptying, and the food additives are good even when the food surface and the container inner surface are not necessarily in close contact with each other. (Especially in the case of moisture transfer). For example, by putting food such as cheese, ham and sausage, dried fish and fish fillets in a deep-drawn container on a transfer sheet coated with a flavoring agent, etc. without sticking, the surface of these foods can be smoothly flavored. You can put it on.

Hereinafter, production examples of transfer sheets for deep drawing packaging according to the present invention, examples of deep drawing packaging methods using the transfer sheets obtained in the above production examples, and various transfer evaluation test examples using the transfer sheets will be sequentially described. .
In addition, this invention is not restrained by the following manufacture example, an Example, and a test example, Of course, arbitrary deformation | transformation can be made within the range of the technical idea of this invention.

<Comprehensive evaluation of transfer test when transfer sheet is applied to deep drawing packaging>
As seen from the above table, since the cellulose derivative alone lacks its function as a binder, Comparative Example 3 supplemented shellac as a binder reinforcing agent, but even in Comparative Example 3, the stability of the transfer agent with time was poor. The subsequent evaluation test was not possible.
In Comparative Example 1 in which dietary fiber was used alone as a binder and Comparative Example 2 in which silicon dioxide was used alone, the transfer agent was set off when the transfer sheet was wound up, so that the printability was inferior.
Comparative Example 4 is the same as Comparative Example 3 in that shellac is added to the cellulose derivative as a binding reinforcing agent, but the stability with time is improved by increasing the content of the cellulose derivative. In the process, color transfer of the transfer agent was observed and the molding suitability was inferior. As a result, transfer defects were partially recognized.
In Comparative Example 5 in which dietary fiber was used in place of the cellulose derivative and shellac was supplemented, cracking of the transfer agent layer was observed in the deep drawing process and the molding suitability was poor. A transfer defect was observed.

On the other hand, in Examples 1 and 2 using a mixture of a cellulose derivative and calcium carbonate as a binder and Examples 3 to 5 using a mixture of silicon dioxide, dietary fiber, and a cellulose derivative, stability over time, printability In addition, the moldability was excellent, and as a result, the food additive was successfully transferred to the food surface.
In Example 6 using a synthetic resin sheet having a high tensile elastic modulus, the elongation of the sheet in the coating process was small, and the adjustment of the coating conditions was easier. On the contrary, in Example 9 using a synthetic resin sheet having a low tensile elastic modulus compared to Example 6, a slight shift in the pitch of the coating occurred, and a shift occurred in the deep drawing mold and the coating part. Transfer defects were found in some of the foods, but there was no problem as a product.
For this reason, when applying a transfer sheet in which a food additive is applied to a base sheet of synthetic resin to deep-drawing packaging, dietary fiber, silicon dioxide, or the like is used as a binder to ensure good transferability. The use of a binder selected from a specific combination such as a mixture of cellulose derivative and calcium carbonate, a mixture of silicon dioxide, dietary fiber and cellulose derivative is proved compared to the case of use.
In particular, in Comparative Examples 4 to 5 in which shellac is added to the cellulose derivative as an auxiliary, the stability over time and the printability are excellent, but there is a problem in the moldability, and as a result, transfer defects occur in part. Even in the case of using a binder as a binder, in order to achieve good transfer suitability as in the present invention, calcium carbonate or a composite of silicon dioxide and dietary fiber is used instead of a shell reinforcing agent such as shellac. It is important to select specific ingredients.
Also, if a sheet with a high tensile modulus is used as the base material sheet for the synthetic resin, the coating pitch will be stable, preventing the occurrence of misalignment between the mold and the coating part in deep drawing and Good transfer of food additives.

In Examples 1 to 5, food additives such as various seasonings and smoke liquids are transferred to various foods. However, when the transfer sheet of the present invention is applied to deep-drawing packaging, it can also be heated and heated. It can be seen that the food additive applied to the transfer sheet can be smoothly transferred to the food surface also by the action.
In particular, focusing on Example 3 in which heat was transferred to raw sausage dough and Example 4 in which moisture was transferred to heated sausage, even if the food on the side to be transferred was a raw material, it was a heated food. It can be seen that both have excellent transferability.
Therefore, foods that can be put into deep-drawn packaging containers can be raw foods or heat-processed products, and the transfer method can be either heat transfer or moisture transfer. The degree of freedom of operation is also good.
Moreover, in Patent Document 1 described above, a fiber layer having water absorption properties such as paper and nonwoven fabric is interposed on the synthetic resin layer. However, in the present invention, synthesis is performed by using a binder that combines specific components. Since a food additive containing a pigment or the like can be applied to the resin base material without hindrance, the base material sheet does not need to have a complicated structure, and productivity is high in both the preparation of the transfer sheet and the transfer operation.

It is a schematic process drawing of deep drawing packaging using a transfer sheet.
