- a magnesium alloy of five or more elements may be used. Magnesium is harmless to the human body and is rather an essential element for the metabolism of the human body.
- the present inventors have also found that when the purity of magnesium is increased, corrosion hardly occurs. Therefore, it is extremely useful to use a multi-layer sheet with a magnesium film as a bag for food packaging, a packaging material for pharmaceuticals, and a packaging material for medical devices such as syringes.
- a magnesium film is formed on a resin film serving as a base film by a vapor deposition method.
- vapor deposition is a method in which a material to be formed into a film is heated and evaporated in a container evacuated to a high vacuum, and the film is deposited on an opposing substrate surface to deposit the film.
- the melting point of magnesium is 65 ° C. when the container is evacuated to about 10 to 3 mmHg using a vacuum pump such as a rotary pump.
- magnesium is instantaneously gasified, thereby strengthening the film and obtaining high adhesion to the base film.
- magnesium is preferentially gasified, and it was found that the material formed had extremely high purity of magnesium. Therefore, it was found that film formation by the vapor deposition method was effective when the original properties of magnesium were expected.
- a magnesium alloy When a magnesium alloy is used as a film forming material in the vapor deposition method, the melting point of the alloy can be reduced. Accordingly, by appropriately setting the degree of vacuum in the container, magnesium can be gasified even at a temperature lower than the above-mentioned heating temperature (300 ° C.). Therefore, if necessary, a desired magnesium alloy may be selected in consideration of, for example, the melting point of the resin film as the material to be deposited.
- the range of vacuum of the container several mm H g to 1 0 one 8 mm H g and extensive Over time, it is possible to deposit magnesium or a magnesium alloy, thereby increasing the degree of freedom in film forming conditions.
- a sputtering method ion plating method
- plasma is generated between a pair of electrodes
- a target magnetium material placed on the cathode is repelled by ions in the plasma
- a film is deposited on the resin film, which is a substrate placed on the opposite anode.
- Argon is generally used as the discharge gas.
- magnesium does not preferentially adhere to the resin film, and the target raw material adheres to the resin film as it is. Therefore, when the composition of the magnesium alloy is directly used as the film material, it is preferable to employ the sputtering method. Further, the sputtering method is advantageous in that the peel strength to the resin film as the substrate is higher than that of the above-described vapor deposition method.
- Magnesium or magnesium alloy film is formed by electron beam method. It is a method to make it. According to the electron beam method, it is possible to form a film even on a magnesium alloy that is difficult to become. In addition, there is an advantage that the evaporation rate is improved and the film forming strength can be increased.
- the base film was a polyester film having a thickness of 12 im, and the composition of the alloy used was as follows.
- the above alloy as a coating material, about 40 OA on the base film under the following deposition conditions was formed. It was found that most of the surface metal of the obtained coating was Mg. Under the same conditions, aluminum oxide and silicon oxide were deposited. Note that the following conditions are also the conditions for vapor deposition of the aluminum film, so the temperature is slightly higher and the degree of vacuum is slightly lower.
- the resulting multilayer sheet was evaluated for paria property.
- MOCON method the water vapor permeability at an ambient temperature of 40 ° (: relative humidity 90 ° / .RH)
- the multilayer sheet according to the present embodiment has extremely excellent water vapor transmission rate and oxygen transmission rate as compared with the multilayer sheet formed by vapor deposition of aluminum oxide or silicon oxide. It turned out that it had.
- the packaging material constituted by the multilayer sheet and the multilayer sheet according to the present invention is not limited to the embodiment described above, and various modifications and improvements are possible within the scope described in the claims.
- a film such as a resin film or paper may be further laminated on one surface side of the above-described multilayer sheet to form a sheet having a multilayer structure of three or more layers.
- the substrate layer is not limited to a resin film, but may be paper or the like.
- an evaporation method of sublimating magnesium or a magnesium alloy from a solid may be used.
- pure magnesium has the property that the shock absorption is extremely high. Therefore, when the material to be packaged is extremely delicate and is resistant to external impacts, the packaging sheet according to the present invention is extremely effective if the packaging material has an appropriate thickness.
- the multilayer sheet provided with the magnesium film according to the present invention is extremely useful as a bag for food packaging, a packaging material for pharmaceuticals, and a packaging material for medical devices such as a syringe.
- the packaging sheet according to the present invention is extremely effective.
