Are known. As one of the methods, there is a method in which a polymer has a functional group having an ion exchange ability or a complex forming ability, and a metal ion is retained in the functional group. However, in this method, the interaction between the functional group and the polymer is performed. Accordingly, the polymer is liable to undergo remarkable change in physical properties, and the type of the polymer and the type and the amount of the functional group that can be used must be extremely limited.

There is a method of imparting this to a polymer (Japanese Unexamined Patent Publication No.
186804), the antibacterial activity may vary due to aggregation or uneven distribution of solid particles, and the physical properties of the polymer such as flexibility and transparency may be impaired. Usually, a large amount (2 to 3% or more) of kneading is required for embedding or the like. In addition, especially for food packaging film, it has good antibacterial properties, good appearance, high commercial value, anti-fogging properties to prevent water droplets that easily become a culture medium for bacteria, and antistatic to prevent dust from adhering. Therefore, there has been a long-awaited demand for the appearance of a food packaging sheet or film having antibacterial properties as well as antifogging properties and antistatic properties.

g, an average particle diameter of 6 μm or less is desirable. Oil absorption is 1
If it is less than 20 ml / 100 g, a long-term antibacterial antifogging property cannot be sufficiently exhibited, and if it exceeds 280 ml / 100 g, a large amount of fatty acid monoglyceride is included, and the efficiency of the effective fatty acid monoglyceride is small, resulting in poor efficiency. If the average particle size is larger than the upper limit, the haze of the film increases,
It is not good because the contents of the package are difficult to see. The mixing ratio of the porous silica and the fatty acid monoglyceride was 0.1% by weight.
~ 1.0: 1 is desirable. More preferably, 0.2 to
0.4: 1. If it is below the lower limit, the fatty acid monoglyceride not supported on the porous silica is too large and there is no long-term release effect, and if it is above the upper limit, the fatty acid monoglyceride is almost completely supported on the porous silica and released to the film surface. Monoglycerides are too low, and antibacterial and antifogging properties are lost.

To 3% by weight, particularly preferably 0.3 to 2% by weight.
Below the lower limit, both the antibacterial and antifogging effects are insufficient.
It is not preferable to add more than the upper limit, for example, the stickiness which is unnecessary as a practical antibacterial effect is increased, and the physical properties of the sheet and the film are greatly changed.

ことが分る。In the low temperature test, place water in a cup and place at 18 ° C. ± 1 ° C.
And the film of Example 1 was covered and sealed.
The area without cloudiness for each elapsed time when left in a refrigerator at ° C. is shown in percentage. Table 3-1 shows the results.
It is shown in Table-3-2. C 8, C 10 by mixing the C 12 C 8, C 10, C 12 it can be seen that each anti-fogging than alone improved.
