Description

  The present invention relates to a non-adhesive lid material used for articles containing moisture and sugar, and a sealed container comprising the lid material and a container.

  Conventionally, cup-shaped containers are widely used as packaging containers for foods such as yogurt, milk potion, pudding, jam, gum syrup, butter, ice cream, pharmaceuticals, and cosmetics. These cup-shaped containers are sealed with a lid material to be heat-sealed. Accordingly, such a lid member is desired to have heat sealability and non-adhesiveness of the contents, that is, to prevent the contents from adhering to the lid material surface on the inner surface side of the packaging container. If the contents adhere to the inner cover side of the packaging container, it may not look good, or the contents may be used up, resulting in waste of fingers, clothes, tables, etc. There is a problem that even if information or the like is printed on the side lid material surface, it cannot be visually recognized.

  Then, the following patent documents 1-6 have been made about the lid | cover material which provided the non-adhesiveness of the content to the lid | cover material surface of the inner surface side of a packaging container in such a lid | cover material of a cup-shaped container.

  In Patent Document 1, a cover material is formed by laminating a content adhesion preventing layer composed of a composition of a wax and a filler dispersed in the wax on a heat-sealing layer. Therefore, there is a concern that the heat-sealing property of the heat-sealing layer is affected and the sealing tends to become unstable. In Patent Documents 2 to 4, it is a laminate or a cover material in which a porous layer having a three-dimensional network structure is formed using hydrophobic oxide fine particles as an adhesion preventing layer on the outer surface of the heat sealing layer. The heat resistance of the layer is inferior, and the anti-adhesion effect may be significantly impaired. That is, in the formation process of the anti-adhesion layer, when the anti-adhesion layer is dried, if the heating temperature is too high or the drying time is long, the anti-adhesion effect is impaired, and thus process management and handling are difficult. . In patent document 5, although it is a lid | cover material which used the hydrophobic wet silica for the adhesion preventing layer, since the low melting point wax is used for the heat sealing layer, the wax melts at the time of heat sealing. There was a problem of inferiority. In Patent Document 6, the water-repellent layer is a lid body in which oxide fine particles are adhered to resin particles made of an olefin resin. It is. Further, these disclosed lid materials have a problem that, when the contents are touched for a long time, the non-adhesion layer deteriorates and the non-adhesion performance cannot be maintained.

  Hereinafter, embodiments for carrying out the present invention will be described in detail. The present embodiment is merely one form for carrying out the present invention, and the present invention is not limited by the present embodiment, and various modifications and embodiments are possible without departing from the gist of the present invention. Is possible.

  The non-adhesive lid material of the present invention (hereinafter also simply referred to as “lid material”) has a configuration in which a heat seal layer, an anchor coat layer, and a non-adhesive layer are laminated in this order on at least one surface of a base material layer. It is a non-adhesive lid material, and the non-adhesive layer is preferably a layer containing talc subjected to a hydrophobic treatment.

  The talc subjected to the hydrophobic treatment is preferably a talc subjected to a hydrophobic treatment (hereinafter also simply referred to as “treated talc”).

  The hydrophobic treatment is not particularly limited as long as a hydrophobic group can be introduced into talc, but silane coupling treatment, silicone treatment, and silazane treatment are preferable from the viewpoint of water repellency, cost, and safety. A known silane coupling agent is used for the silane coupling treatment, and the treatment to the inorganic filler such as talc is preferably a dry method or a wet method. In general, a silane coupling agent is a silane compound having two different functional groups of an organic functional group and an alkoxy group in one molecule, such as aminopropylmethoxysilane, aminopropyltriethoxysilane, ureidopropyltriethoxysilane, N- Aminosilane coupling agents such as phenylaminopropyltrimethoxysilane, N-2 (aminoethyl) aminopropyltrimethoxysilane, glycidoxypropyltrimethoxysilane, glycidoxypropyltriethoxysilane, glycidoxypropylmethyldiethoxy Epoxysilane coupling agents such as silane, glycidylbutyltrimethoxysilane, (3,4-epoxycyclohexyl) ethyltrimethoxysilane, mercaptopropyltrimethoxysilane, mercaptopropyltrie Mercaptosilane-based coupling agents such as toxisilane, silane-based coupling agents such as methyltrimethoxysilane, octadecyltrimethoxysilane, phenyltrimethoxysilane, methacroxypropyltrimethoxysilane, imidazolesilane, and triazinesilane are used. For example, a dry method is known in which an inorganic filler is stirred at a high speed with a stirrer, and a stock solution of a silane compound is uniformly dispersed therein and treated. A wet method is obtained by immersing an inorganic filler in a dilute solution of silane. Methods for processing are known. A silicone oil that is liquid at room temperature is used for the silicone treatment. The silicone oil is not particularly limited as long as it has a polysiloxane structure, but dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane and the like are more preferable. It is preferable to process with respect to talc using 1-5 mass% of silicone oil. For silazane treatment, organosilazanes such as hexamethyldisilazane (HMDS), hexaphenyldisilazane, dimethylaminotrimethylsilane, trisilazane, cyclotrisilazane, 1,1,3,3,5,5-hexamethylcyclotrisilazane, etc. A compound is preferably used, and hexamethyldisilazane is more preferably used. For example, a method of spraying hexamethyldisilazane with talc flowing, or adding talc in an organic solvent such as alcohol or toluene, adding hexamethyldisilazane and water, and then adding water and organic solvent Can be prepared by a method of evaporating and drying with an evaporator. More specifically, HMDS-treated talc can be produced by putting talc into a Henschel mixer, spraying water and HMDS while stirring in a nitrogen atmosphere, heating, cooling, and crushing with a ball mill.

  Talc is a mineral made of magnesium hydroxide and silicate, a kind of clay mineral. Although talc itself has a certain degree of hydrophobicity even when it is not treated, it is not sufficient for the water repellency and non-adhesiveness which are the subject of the present invention, and it needs to be subjected to a hydrophobic treatment. The hydrophobizing treatment may be a general one, and silica treatment, silicone treatment (siloxane treatment), silazane treatment, resin treatment, fatty acid treatment, silane coupling treatment, titanate treatment, or a combination treatment thereof may be performed. Any may be used. The treatment amount is preferably 0.01 to 50% by mass and more preferably 0.05 to 30% by mass with respect to talc. If it is less than 0.01% by mass, the hydrophobicity is not sufficient, and if it is more than 50% by mass, it does not contribute to the treatment of talc, but it becomes an impurity and inhibits water repellency. For example, the treated talc can be obtained by spraying a 10% methylene chloride solution of silicone oil on the talc so that the silicone oil is 1 to 5% by mass, and baking treatment at 100 ° C. for 2 hours.

  The non-adhesion layer containing the treated talc has an effect of improving heat sealability.

  The non-adhering layer may contain inorganic particles such as silica, sericite, mica, and kaolin. By using the inorganic particles in combination, the stability of the coating liquid for the non-adhesion layer is improved, and the coating suitability is improved. Furthermore, the inorganic particles are preferably subjected to a hydrophobic treatment. The hydrophobic treatment of the inorganic particles can be performed by the same method as the hydrophobic treatment of talc.

Is more preferable. If it contains 0.001 μm or less, water repellency is hardly expressed, and if it is larger than 50 μm, the friction resistance is poor. An average particle diameter here is a measured value by the laser method (made by MICROTRAC 9320 * 100 Honeywell).

In the case of treated talc, the thickness is preferably 20 μm or less, and more preferably 10 μm or less.

Is more preferable. When the treatment talc is less than 1, the effect of improving the heat sealability is hardly exhibited. As the content of treated talc increases, the non-adhesion layer becomes whitish. Therefore, if you want to ensure transparency, it is effective to adjust the weight ratio of treated talc and inorganic particles to the extent that heat sealability is not impaired. It is. In addition, when the coating liquid is used, the processing talc in the coating liquid may become unstable depending on its composition, viscosity, dilution, etc. It is effective to adjust the ratio.

  The amount of the treatment talc or the treatment talc and the inorganic particles in the coating solution is preferably 0.1 to 50% by mass, more preferably 1 to 40% by mass, More preferably, it is 30 mass%. If the amount is less than 0.1% by mass, the water repellency of the non-adhesive layer coated with the coating liquid is difficult to be expressed. If the amount is more than 50% by mass, the fluidity as the coating solution is poor, and coating by the gravure printing method Not suitable for.

  Furthermore, the film thickness of the non-adhesion layer formed by applying the coating liquid is preferably 0.01 to 50 μm, and more preferably 0.01 to 30 μm.

It is preferable that 0.1 g / m ² ≦ UC ≦ 1 g / m ² is more preferable. When the amount is less than 0.02 g / ^{m 2,} the water repellency is hardly expressed, when more than 1.5 g / ^{m 2,} abrasion resistance of the non-adherent layer is poor.

  The anchor coat layer preferably contains a resin having a glass transition point (hereinafter also simply referred to as “Tg”) of 0 ° C. or more and less than 100 ° C., more preferably 10 ° C. or more and 90 ° C. or less, and more preferably 20 ° C. or more. 80 degrees C or less is still more preferable. When Tg is lower than 0 ° C., stickiness is likely to occur, the stability of the non-adhesion layer is lowered, and the non-adhesion property is lowered. When it is 100 ° C. or higher, the heat seal strength becomes weak. In particular, when Tg is within the above range, the non-adhesion layer is stabilized, and the non-adhesion performance as a lid material is maintained for a long time without deterioration.

  The heat sealant preferably has a solid content in the composition of 0.1 to 90% by mass in coating suitability, more preferably 2 to 70% by mass, and 3 to 50% by mass. More preferably. When it is less than 0.1% by mass, the heat seal layer becomes thin and the strength is inferior. If it is more than 90% by mass, it will be difficult to dissolve or disperse, making it difficult to produce the heat sealant itself, increasing the viscosity, and causing problems in coating properties.

  The film thickness of the heat seal layer formed by applying the heat sealant is preferably 0.01 to 30 μm. Those having a film thickness of less than 0.01 μm are less likely to exhibit water repellency, and those having a film thickness of more than 30 μm are difficult to produce by coating.

The heat seal layer formed by applying the heat-sealing material, the total coating amount of heat-sealing material (HC) is a layer of ^{0.3g / m 2 ≦ HC ≦ 10g} / m 2 on a solids It is preferable that 0.6 g / m ² ≦ HC ≦ 8 g / m ² . When the total of HC is smaller than 0.3 g / m ² , the heat seal strength is weakened, and when it exceeds 10 g / m ² , blocking becomes easy and cost effectiveness is lost.

  The heat seal layer formed by applying the heat sealant containing the heat sealable resin, the filler and the like becomes uneven in the cross section. By being uneven, good water repellency and non-adhesiveness can be obtained.

  The heat seal layer formed by applying the heat sealant may be one layer as long as the total coating amount (HC) of the heat sealant is within the above range. It can also be provided as described above, and it becomes easy to control the heat seal strength. When two or more layers are provided, a heat sealant having the same resin composition may be applied, but a heat sealant having a different resin composition may be used and can be appropriately selected.

  One or more printing ink layers (hereinafter also simply referred to as “printing ink”) can be applied to the base material layer, and a printing ink layer can be provided between the opposite surface of the non-adhesion layer or between the base material layer and the non-adhesion layer. It can also be provided. By applying a printing ink layer to the base material layer, for example, company name, product name, contents, component display, scale, scale line, notification of application method and campaign, how to eat and use, date, Information such as place of origin and winning lottery can be given. An OP varnish layer can also be applied on the printing ink layer.

  Moreover, it is not necessary that the space between the base material layer and the heat seal layer is solid, and one or more printing ink layers can be applied to the base material layer.

  As the printing ink layer, a normal gravure ink can be used, and can be appropriately selected according to the base material layer. From the viewpoints of printability and versatility, gravure inks such as urethane resin, vinyl chloride-vinyl acetate copolymer resin, nitrified cotton, polyamide resin, (meth) acrylic resin, and chlorinated polypropylene resin are preferable. It may be a gravure ink of a type or a combination of two or more types. Moreover, when using the gravure ink of 2 or more colors, it is not necessary to be the same resin-type ink, and another resin-type ink can also be used suitably.

  Examples of commercially available products include LG-NT, TPH, VESTA, LRC-NT, KCNT, SYNA-S, and LAMREK (all of which are manufactured by Tokyo Ink Co., Ltd.).

  The anchor coat layer and the non-adhesion layer are formed by applying the anchor coat agent or the coating liquid to the base material layer by a known method such as printing, coating, spraying, or dipping. Examples of the coating method include a silk screen printing method, a gravure printing method, an offset printing method, a flexographic printing method, a roller coater method, a brush coating method, a spray method, and a knife jet coater method. Of these, the gravure printing method, flexographic printing method or silk screen printing method is preferably used because of high quality and productivity, and the gravure printing method using a multicolor gravure printing machine is particularly preferable. Moreover, a heat seal agent can also form a heat seal layer with the said application | coating method. Thus, the cover material has a configuration in which a heat seal layer, an anchor coat layer, and a non-adhesion layer are laminated in this order on the base material layer. More specifically, after the base material layer laminated by the laminating method described above is created, the heat seal layer, the anchor coat layer, and the non-adhesion layer are formed in this order by the gravure printing method, or the base material serving as a base An anchor coat layer and a non-adhesion layer may be formed on one side of the layer by a gravure printing method, and another base material layer may be formed on the other side different from this by the laminating method described above. Alternatively, after forming a heat seal layer by bonding a sealant film to the base material layer, resin coating by extrusion lamination, etc., an anchor coat layer and a non-adhesion layer are formed on the surface of the heat seal layer by gravure printing. It may be formed. The anchor coat layer and the non-adhesion layer may be provided on both surfaces of the base material layer.

The formation of the heat seal layer by the anchor coat layer, the non-adhesion layer and the heat sealant is preferably performed by a gravure printing method using one unit or more of a multicolor gravure printing machine. This makes it possible to continuously form a printing ink layer, heat seal layer, anchor coat layer, and non-adhesive layer on the base material layer in-line, and reduce the non-adhesive lid material in a series of flows (one pass). It can be easily manufactured at a low cost. In addition, the adhesion and non-adhesion control of the non-adhesion layer and the heat seal strength can be easily controlled. Of course, there may be cases where the gravure printing machine cannot be continuously formed inline due to restrictions such as the specifications of the gravure printing machine, the printing environment, and the equipment. The anchor coat layer is preferably applied only to the portion where the non-adhesion layer is provided.
The adhesiveness of the non-adhesive layer means whether or not the surface having the non-adhesive layer and the partial surface or the entire surface of the article are likely to stick to each other. The non-adhesive control means that it is possible to control the difficulty of sticking the surface having the non-adhesive layer and a part of the food or the entire surface of the food. In the present specification, the non-adhesive layer means to be interpreted as a surface having a non-adhesive layer.

  Furthermore, when a non-adhesion layer is formed by gravure printing, the 100% halftone dot area ratio may be reduced by the area ratio if the non-adhesion property is too high, or depending on the degree of non-adhesiveness to food. By adjusting the depth or adjusting the dilution rate, the adhesion between the non-adhesive lid and the article can be easily controlled. In addition to adjusting the halftone dot area ratio and plate depth, characters (for example, manufacturer name, brand name, product name, symbol, etc.) and patterns (for example, marks, marks, designed designs, etc.) can be removed. By forming the film (forming a part having no non-adhesion layer), the “extracted” part adheres to the article and maintains an appropriate adhesion, and also has the effect that characters and patterns stand out.

  Each composition such as the anchor coating agent, non-adhesive layer coating liquid, printing ink, heat seal agent, hydrophobic resin, unevenness imparting agent, pigment, treatment talc, inorganic particles, heat seal resin, various additives, etc. Can be produced by a known method by uniformly dissolving or dispersing in a solvent. Dissolver or disperser is various agitators or dispersers such as dissolver, roll mill, ball mill, bead mill, sand mill, attritor, paint shaker, agitator, Henschel mixer, colloid mill, pearl mill, ultrasonic homogenizer, wet jet mill, kneader, homomixer, etc. You can use the machine. These devices may be used alone or in combination of two or more. When air bubbles and coarse particles are contained in each composition, it is preferable to remove them using a known filter or centrifuge in order to reduce printability and print quality.

  The viscosity of each composition is not particularly limited as long as it does not interfere with printing. Considering the production suitability and handling of each composition, it is preferably 10 to 1,000 mPa · s at 25 ° C.

  The viscosity can be measured using a commercially available viscometer such as a Brookfield viscometer.

  Each of the above compositions can be applied as it is, but depending on the coating conditions and the coating effect, the desired viscosity can be obtained by diluting with a diluting solvent in Zahn Cup # 3 (manufactured by Kogaisha Co., Ltd.). It can be used after adjusting. The viscosity in this case is preferably 10 to 40 seconds at 25 ° C.

  The dilution solvent may be any one as long as it can be used after adjusting the viscosity of each composition, and examples thereof include organic solvents and water, and commercially available ones can also be used. Commercially available products include WA735 (alcohol solvent), TA52 (alcohol solvent), PU515 (non-toluene solvent), SL9155 (non-toluene solvent) (all of which are manufactured by Tokyo Ink Co., Ltd.). .

  The method for producing a non-adhesive lid material of the present invention includes a step in which a heat seal layer, an anchor coat layer, and a non-adhesion layer are laminated in this order on at least one surface of a base material layer, and the anchor coat layer is formed. And a step of forming a non-adhesion layer by applying a coating solution containing talc that has been subjected to hydrophobic treatment.

  The step of forming the anchor coat layer and the non-adhesion layer is preferably a step of forming the substrate layer by known printing or coating, spraying, dipping, etc., and more preferably a coating step. Examples of the coating process include silk screen printing, gravure printing, offset printing, flexographic printing, roller coating, brush coating, spraying, knife jet coating, and the like. Especially, the application process by gravure printing, flexographic printing, or silk screen printing is used preferably from the height of quality and productivity, and it is especially preferable that it is the application process by gravure printing using a multicolor gravure printing machine. By these forming steps, a non-adhesive lid member having a configuration in which a heat seal layer, an anchor coat layer, and a non-adhesive layer are laminated in this order on at least one surface of the base material layer is obtained. More specifically, after the step of creating the base material layer laminated by the formation step described above, the step of forming the anchor coat layer and the non-adhesion layer in this order by gravure printing is performed, and the non-adhesive lid material is manufactured. However, after the step of forming the anchor coat layer and the non-adhesion layer by gravure printing on one surface of the base material layer that becomes the base, another base material is formed by the above-described forming step on the other surface. You may manufacture a non-adhesive cover material by the process of laminating | stacking a layer further. Moreover, you may manufacture a non-adhesive cover material by the process in which a non-adhesion layer can be formed on both surfaces of a base material layer.

  By these steps, since the anchor coat layer and the non-adhesion layer can be formed in multiple layers, the adhesion and non-adhesion of the non-adhesion layer can be easily controlled. That is, the non-adhesive lid material using the conventional embossing or plasma chemical vapor deposition method is inefficient because the production of the non-adhesive layer is a separate process and is inefficient. Is a formation process by gravure printing using a multi-color gravure printing machine, so it is possible to form a printing ink layer, an anchor coat layer, and a non-adhesion layer on the base material layer continuously in-line. The non-adhesive lid material can be easily produced at a low cost in one pass). Of course, there may be cases where the gravure printing machine cannot be continuously formed inline due to restrictions such as the specifications of the gravure printing machine, the printing environment, and the equipment. In this case, formation in an offline (outline) is also possible. The anchor coat layer is preferably applied only to the portion where the non-adhesion layer is provided.

  The non-adhesive lid material can be cut by cutting, dividing, die-cutting, etc. into a size and dimension that suits the purpose, depending on the type, shape and size of the article, the container to be sealed, etc. . The mounting position of the non-adhesive lid material is preferably a portion where the article should not adhere to the lid material, and any of the lower surface (as a laying material), the upper surface or the side surface (may be provided around) It may be.

  The non-adhesive lid material of the present invention is preferably a closed container by being in close contact with the container. The close contact with the container may be performed through human hand, but a machine such as an automatic sealing device may be used. These may be selected as appropriate depending on the type, form and size of the food, quantity, container to be sealed, equipment, environment, etc., and sticking or bonding with heat seal (hot pressure seal), face seal, adhesive, etc. It may be performed by a method using such as.

More preferably, the container is a bottomed cylindrical container. In this case, the non-adhesive lid material covers the opening of the bottomed cylindrical container and is preferably sealed, and more preferably sealed by hot pressure sealing. As the heat pressure sealing condition, a non-adhesive lid material is placed so as to cover the opening of the bottomed cylindrical container, and ranges from 120 to 250 ° C., ² to 10 kgf / cm ² , and 0.5 to ² sec. Therefore, the number of times of sealing 1 to 2 may be selected as appropriate.

  Examples of the resin used in the container include thermoplastic resins such as polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, polystyrene, and polyacrylonitrile. As described above, since the heat seal layer can be formed in multiple layers, for example, the adhesion between the lid made of a polyester base layer such as polyethylene terephthalate and the opening of the container made of polystyrene resin can be sufficiently enhanced. In this case, “PET (base material layer of cover material) / sealing layer having high affinity for PET (first heat sealing layer) / sealing layer having high affinity for polystyrene (second heat sealing layer) / A container such as “anchor coat layer / non-adhesion layer / polystyrene (resin layer of container)” can be easily produced.

  As the form of the sealed container, a two-side seal, a three-side seal, a four-side seal, a pillow seal, a standing pouch, an envelope sticker, a gusset, a fusing seal, a tube, a caramel packaging, an overhold, a fin seal, a manju packaging, a twist, a rocket, Any of well-known forms such as Tetra Pak, Gable Top, Brick, Shibori, and Cup may be used.

  The non-adhesive lid material of the present invention is a sealed container in which the non-adhesive layer and the article are always in contact with each other because the non-adhesive layer is stable and the non-adhesive performance is maintained for a long time without deterioration. Good. Further, it is not always necessary to be in contact with the article, and it may be a sealed container provided with a gap that does not contact the non-adhesive layer of the non-adhesive lid material with the article. As a result, even if a part or the entire surface of the article physically contacts the non-adhesive layer of the non-adhesive lid material during transportation, transportation, transportation, vibration, tilting, rollover, transposition, etc. of the closed container, There is an effect that adhesion of articles can be prevented or reduced.

  Examples of the non-adhesive lid material of the present invention will be described, but the present invention is not limited thereto.

  The non-adhesive lid materials of Examples 6 to 14, 20 to 25 and Comparative Examples 4 to 9 were evaluated for water repellency, non-adherent yogurt property, heat sealability, and durability, and are shown in Table 1.

<Water repellency>
The contact angle was measured for the non-adhesive layer of the non-adhesive lid. For the measurement, a portable contact angle meter PCA-1 (manufactured by Kyowa Interface Science Co., Ltd.) was used. The larger the measured value, the higher the water repellency and the better.
A: 130 ° or more, ○: less than 130 ° 110 ° or more, Δ: less than 110 ° 90 ° or more, and x: less than 90 °.

<Non-adhesive yogurt>
Place one drop of yogurt (Bhiidas Yogurt, manufactured by Morinaga Milk Industry Co., Ltd.) on the non-adhesive layer of the non-adhesive lid placed in a horizontal state, and slowly tilt one side of the non-adhesive lid. The angle at which the yogurt rolled down was observed. As the angle is smaller, yogurt is less likely to adhere and the yogurt non-adhesiveness is excellent.
A: 30 ° or less, ○: more than 30 ° to 60 ° or less, Δ: more than 60 ° to 90 ° or less, and x: more than 90 °.

<Heat sealability>
A non-adhesive lid and a polystyrene sheet having a thickness of 0.15 mm are heat-pressure sealed (ring seal) in a ring shape at 220 ° C. for 1 second under a load of 3 kgf / cm ² , and then the ring seal portion is long. The sample piece was made into a strip shape with a width of 15 mm so as to be substantially perpendicular to the side. This sample piece was pulled with a universal tensile tester (RTE-1210, manufactured by Orientec Co., Ltd.) under the conditions of a peeling angle of 180 ° and a tensile speed of 300 mm / min. Measured as (g). The greater the seal strength, the better the heat sealability.
A: 400 g or more, ◯: less than 400 g, 350 g or more, Δ: less than 350 g, 300 g or more, and x: less than 300 g.

<Durability>
Place a drop of yogurt (trade name: Bihidas Yogurt, Morinaga Milk Industry Co., Ltd.) on the non-adhesive layer of the non-adhesive lid placed in a horizontal state, cover the yogurt to prevent it from drying, and leave it for 24 hours. It was left in the refrigerator. After that, remove the non-adhesive lid from the refrigerator, remove the cover, and then slowly lift up one side of the non-adhesive lid and tilt the yogurt from the non-adhesive layer of the non-adhesive lid The state was observed visually. The excellent durability means that even if the contents are in contact with the non-adhesive layer of the non-adhesive lid material for a long time, the non-adhesive performance is not deteriorated and persists. Therefore, the yogurt that rolls off from the non-adhesive layer of the non-adhesive lid material is considered to have excellent durability.
(Double-circle): Yogurt rolled down and there was no adhesion (durability is excellent), x: Yogurt did not roll down and adhered as it is (it is inferior in durability), and evaluated in two steps.

<Comprehensive evaluation>
Of the water repellency, non-adherent yogurt, heat sealability, and durability, the evaluation results are all “◎” as the overall evaluation, and the evaluation results are “◎” or “○” as the overall evaluation. An evaluation with “◯” or even one “Δ” was “△” as a comprehensive evaluation, and an evaluation with “×” was “×” as an overall evaluation.

  According to Table 1, the non-adhesive lid materials of Examples 6 to 14 and 20 to 25 are water repellent, non-adherent to yogurt, heat sealability, and durability as compared with the non-adhesive lid materials of Comparative Examples 4 to 9. It is clear that is superior. Comparative Example 4, which is an example using a non-adhesive layer coating solution containing talc that has not been hydrophobized (untreated talc), has poor water repellency and non-adhesiveness to yogurt, and yogurt adheres to the lid. . Comparative Example 5 and Comparative Example 6, which are examples using a non-adhesive layer coating solution containing no treated talc, have good water repellency, non-adherent yogurt properties and durability, but have poor heat sealability. Comparative Example 7, Comparative Example 8, which is an example in which a non-adhesion layer is not formed, and Comparative Example 9, which is an example in which a silicone resin as a conventional example is applied, have no effect on non-adhesion.

  According to the non-adhesive lid material of the present invention, since it has sufficient non-adhesiveness and can be easily manufactured at low cost, it can be effectively used as a non-adhesive lid material to which articles do not adhere. In addition, the degree of non-adhesive requirement may vary depending on the article, application, and form. In such a case, the non-adhesive lid material can be reduced by reducing the dot area ratio of the gravure plate or adjusting the plate depth. Adhesion between food and food can be easily controlled. Moreover, heat seal intensity | strength can be adjusted easily by changing the content rate of a process talc. Furthermore, because it is extremely excellent in durability, after filling a cup-shaped container with yogurt or the like, it is sealed with the non-adhesive lid of the present invention, and when it is distributed as a product, vibration or transposition during the process of transportation, transportation, etc. Even if yogurt or the like has been in contact with the cover material for a long time due to rollover, the yogurt or the like will not leave the cover material and will not continue to adhere to it when it is placed in place. There is a risk that the product will not look bad at the time of product display, etc., or that there will be no waste due to being able to use up the contents when the lid is opened, and the fingers, clothes, table, etc. may be damaged In addition, there is an excellent effect that the information can be used for displaying information for a customer such as a campaign, a method of using an article, a method of eating, etc. on the inner surface of the lid material. Furthermore, since it can be applied by a gravure printing method, it can be widely applied not only to food applications but also to various water-repellent lids for daily necessities, medical drugs and industrial materials, and packaging containers using the same.
