Description

  INDUSTRIAL APPLICABILITY The present invention is suitably used as a sealant film for a laminated film having a barrier property such as oxygen and water vapor, and forms a vapor deposition layer such as a metal thin film such as aluminum or a metal oxide thin film such as aluminum oxide. The present invention relates to a multilayer sealant film for vapor deposition.

  As a sealant film constituting a laminated barrier film for packaging having a barrier property against oxygen or water vapor, a vapor-deposited CPP film in which an aluminum thin film or the like is vapor-deposited on one surface of a CPP film (cast polypropylene film) that is an unstretched polypropylene resin ( VMCPP film) is known. A base film such as a biaxially stretched polypropylene film (OPP film) or a biaxially stretched PET film is further laminated on the vapor deposition surface side to constitute a laminated barrier film for packaging. However, the barrier property of the deposited CPP film is not sufficient, and a higher barrier property is required.

  On the other hand, polyethylene-based resins have poorer barrier properties than VMCP from the viewpoint of smoothness and polarity, and have been made unsuitable as a sealant film for vapor deposition. However, as described in Patent Document 1, a cyclic olefin-based resin is used. The resin is excellent in vapor deposition suitability.

JP-A-9-123351

  Taking advantage of the vapor deposition suitability of this cyclic olefin resin, the cyclic olefin resin layer / sealant layer is multi-layered, and attempts have been made to achieve both the vapor deposition suitability (barrier property) and heat sealability of the sealant film. . However, compared with amorphous cyclic olefin resin, crystalline polyethylene resin and polypropylene resin have a high shrinkage rate. For this reason, when a multilayer is formed with a cyclic olefin resin layer / sealant layer, the raw material for vapor deposition is obtained. A large curl occurs. In the post-deposition process, the roll-to-roll process needs to be performed at high speed in a vacuum chamber, so the original film for vapor deposition that causes curling lift during vapor deposition can be a fatal defect. Cannot be used for

  These cyclic olefin components may be used singly or in combination of two or more. Among these, it is preferable to use bicyclo [2.2.1] hept-2-ene (common name: norbornene) alone. In particular, if a copolymer of norbornene and ethylene is used as the cyclic olefin-based resin, it is preferable because the problem of crushed back hardly occurs.

  [1] The polymerization method of the α-olefin component having 2 to 20 carbon atoms and the cyclic olefin component represented by [2] general formula (I) and the hydrogenation method of the obtained polymer are particularly limited.

  It is preferable that the glass transition point of cyclic olefin resin is 30 degreeC or more and 140 degrees C or less. If the glass transition point of the cyclic olefin-based resin is 30 ° C. or higher, it is preferable because the surface state after the pretreatment is maintained at room temperature even after the pre-deposition treatment such as corona treatment. If the glass transition point of cyclic olefin resin is 140 degrees C or less, since it is near the processing temperature with polyethylene and a polypropylene, it is preferable because the blending and lamination | stacking of resin are easy. Moreover, if the glass transition point of cyclic olefin resin is 140 degrees C or less, since adhesiveness with various polyolefin is favorable, an adhesive layer is unnecessary when producing a laminated film. The glass transition point of the cyclic olefin resin can be adjusted by adjusting the content of the cyclic olefin skeleton of the main chain. Moreover, the glass transition point (Tg) employ | adopts the value measured on temperature rising rate 10 degree-C / min conditions by DSC method (method of JISK7121 description).

  Content of cyclic olefin resin contained in a vapor deposition base material layer is 60 mass% or more and 100 mass% or less, Preferably it is 70 mass% or more. If it is less than 60% by mass, vapor deposition suitability such as barrier properties and film adhesion strength is lowered, which is not preferable. Since the vapor deposition substrate layer in the film of the present invention contains a cyclic olefin-based resin, when the film is subjected to a surface treatment (such as corona discharge treatment), the film surface is easily activated, and the film surface is hydrophilic. Is maintained for a long time. As a result, the adhesion strength between the film of the present invention and the metal film is improved.

  Other resins contained in the vapor deposition substrate layer are not particularly limited, but polyethylene resins (linear low density polyethylene, linear low density polyethylene, high density polyethylene, modified polyethylene, etc.), polypropylene, polyethylene elastomer, etc. Is mentioned. The above resins may be used alone or in combination. When the above resins are used in combination, the ratio can be appropriately adjusted according to the processability of the film to be obtained. Of the above resins, it is preferable to combine linear low-density polyethylene and / or linear low-density polyethylene and high-density polyethylene in that the processability of the resulting film is excellent.

[Sealant layer]
The sealant layer is composed of a sealant resin and a cyclic olefin resin of 10% by mass to 40% by mass.

  Since the same thing as what is used in a vapor deposition base material layer can be used for cyclic olefin system resin in a sealant layer, it omits about details. When the cyclic olefin-based resin is included in the sealant layer, the degree of thermal shrinkage of the vapor deposition base material layer and the sealant layer is reduced, so that the shrinkage of the entire film is suppressed and a film with less curling can be obtained.

  As the sealant resin, known resins usually used for films can be used. For example, polyethylene resin (linear low density polyethylene, linear low density polyethylene, ethylene / vinyl acetate copolymer, ionomer, acrylic copolymer, etc.), polypropylene resin (unstretched polypropylene resin, etc.), polyethylene elastomer , Etc. The above resins may be used alone or in combination. When the above resins are used in combination, the ratio can be appropriately adjusted according to the processability of the film to be obtained. Of the above resins, the use of a polyethylene resin and / or a polypropylene resin is preferable in that heat shrinkage of the obtained film can be particularly suppressed, and linear low density polyethylene (LLDPE) or polypropylene resin (PP) is preferable. Is particularly preferred. By using linear low density polyethylene as the sealant resin, it is possible to give a good heat sealability to the form. Moreover, it is preferable to use a polyethylene elastomer blended with a linear low density polyethylene because the shrinkage of the sealant layer can be suppressed.

[Middle layer]
Between the vapor deposition base material layer and the sealant layer, an intermediate layer containing the above sealant resin may be disposed. Since the sealant resin in the intermediate layer can be the same as that used in the sealant layer, the details are omitted. When the intermediate layer is provided on the film of the present invention, the processability of the film is improved.

<Multilayering method>
The method for producing each layer of the present invention is not particularly limited, and for example, it can be produced by a conventionally known extrusion molding method (such as a T-die multilayer coextrusion method) or inflation molding.

  The composition ratio of the thickness of the vapor deposition substrate layer, the sealant layer, and optionally the intermediate layer in the film of the present invention is not particularly limited, but the vapor deposition substrate layer containing a large amount of the cyclic olefin-based resin can be made thin. The difference in heat shrinkage between the front and back of the film (specifically, the difference in heat shrinkage between the vapor deposition substrate layer and the sealant layer) is reduced, and a film with less curling can be obtained. Specifically, the thickness of the vapor deposition base material layer is preferably 5% or more and less than 40% of the total layer thickness, and preferably 5% or more and less than 20% of the total layer thickness. As an example, a layer structure such that the thickness of the vapor deposition base layer: the thickness of the intermediate layer: the thickness of the sealant layer = 1: 3: 4 can be exemplified. The total layer thickness of the film of the present invention is not particularly limited, but is preferably 10 μm or more and 100 μm or less.

<Vapor deposition sealant film>
The film of the present invention is a so-called film for vapor deposition. In the subsequent vapor deposition process, the vapor deposition base material layer is provided on the other surface with respect to the surface on which a sealant layer described later is provided in order to improve barrier properties. In the subsequent vapor deposition step, a vapor deposition layer is provided to form a vapor deposition sealant film. The layer (deposition layer) deposited on the deposition base layer may be, for example, a metal (aluminum, copper, etc.) or an inorganic oxide (aluminum oxide, silicon oxide, ITO, or a mixture thereof). . The formation method of a vapor deposition layer is not specifically limited, A conventionally well-known physical vapor deposition method, a chemical vapor deposition method, etc. can be applied and it does not specifically limit.

  At this time, since the film of the present invention has less curling, no float or the like occurs in the vapor deposition apparatus, and the film becomes an original film for vapor deposition that has excellent handling properties and a high yield in the vapor deposition process. Moreover, since the film of this invention contains a highly rigid cyclic olefin resin, its elastic modulus is high, and even if tension is applied, wrinkles are unlikely to occur. Such an effect is extremely important in a batch type vapor deposition process that handles a raw material having a width of 1 m or more and a length of several thousand m or more.

  The vapor-deposited sealant film thus obtained has a high film adhesion strength because the vapor-deposited layer is formed on the surface of the vapor-deposited substrate layer containing a large amount of cyclic olefin resin, and as a result, the oxygen barrier property is high. In addition, the barrier property of the film in the present invention is indirectly determined by measuring the adhesion strength of the film to the base material by performing a tensile test in accordance with ISO527-2 / 1A after the film is bonded to the base material by lamination or the like. The barrier property was evaluated.

<Laminated barrier film for packaging>
Since said vapor deposition sealant film has few curls in a vapor deposition process, it can be used suitably as a sealant film of the laminated barrier film for packaging which has barrier | blocking properties, such as oxygen and water vapor | steam. Specifically, a base film such as OPP or biaxially stretched PET is laminated on the vapor deposition surface side of the vapor deposition sealant film via polyethylene or an adhesive, for example, stretched base film / adhesive layer / deposition. It becomes a laminated barrier film for packaging having a structure of layer / deposition base layer / sealant layer. For the multi-layering, a known laminating method such as an extrusion coating method, a hot lamination method, or a dry lamination method can be used. Such a laminated barrier film for packaging can be suitably used as various packaging materials that require oxygen barrier properties and water vapor barrier properties such as confectionery (potato chips, candy, chocolate, etc.).
